My father loved to tell this story: One of his classmates while he attended the University of Pennsylvania School of Dental Medicine was named Robert Schattner. Several years after they graduated, he went on to invent the over-the-counter sore throat lozenge and spray called Chloraseptic. This remedy has been on the market for decades ever since then.

Schattner first devised this product entirely on his own after someone who had just had some teeth pulled asked him for an antiseptic to relieve the pain. He later sold the formula and the rights to a pharmaceutical company for $4M. (Given the rate of inflation since then, this sum today would have been magnitudes more and certainly nothing to sneeze or cough at.)

Thereafter he left the practice of dentistry and went on became a successful businessman and philanthropist. He also contributed for the construction of a new building for the U Penn dental school named the Robert Schattner Center. A brief summary of his invention and contributions can be found in an article entitled Capital Buzz: Chloraseptic Inventor Offers Remedy for School, by Thomas Heath, which appeared in The Washington Post on October 23, 2011.

Mapping the Inventive Process

This is a classic example of how inventors find their ideas and inspiration. There are many other circumstances, methodologies, environments, personality traits, events, technologies and chances occurrences that can also precipitate new inventions. All of them are expertly explained and explored in Inventology: How We Dream Up Things That Change the World (Eamon Dolan/Houghton Mifflin Harcourt, 2016), by Pagan Kennedy.

The book’s five sections distinctly map out the steps in the inception and realization of things so entirely new. In doing so, the author transports the reader to center of this creative process. She deftly uses highly engaging stories, exposition and analyses to illuminate the resourcefulness and persistence of inventors leading to their breakthroughs.

Some of these tales may be familiar but they are skillfully recounted and placed into new contexts. For example, in 1968, an engineer and inventor named Douglas Englebart demonstrated a working computer for the first time with a heretofore unseen “mouse” and “graphical user interface”. (This story has gone on to become a tech legend known as The Mother of All Demos.) Others are presented who are less well-known but brought to life in highly compelling narratives. Together they provide valuable new lessons on the incubation of inventions along a wide spectrum ranging from sippy cups and water toys to mobile phones and medical devices.

The author has seemingly devised a meta-invention of her own: A refreshingly new perspective on reporting the who, what, where and why of inventors, their creations and their wills to succeed. It is a richly detailed schematic of how a creative mind can conceive and execute an original idea for a new widget and, moreover, articulate the need for it and the problem it solves.

Among other methods, Ms. Pagan covers the practice of conducting thought experiments on new concepts that may or may not lend themselves to actual experimentation in the real world. This process was made well-known by Einstein’s efforts to visualize certain problems in physics that led him to his monumental achievements. I suggest trying a thought experiment here to imagine the range of the potential areas of applications for Inventology to evaluate, in an age of countless startups and rapid scientific and technological advancements, all of the populations, challenges and companies it might benefit. Indeed, this book could readily inspire nearly anyone so inclined to pick up a pencil or soldering iron in order to launch the realization of their own proverbial better mousetrap.

Resources for Inventors

Within all of the lively content packed into this book, the struggles and legacy of a previously little known and tragically persecuted figure who learned to harness and teach the inventive process, springs right off the pages. He was a fascinating figure named  Genrich Altshuller who worked as an engineer, writer and inventor in Russia. His most important contribution to the science of invention was the development of the Theory of Inventive Problem Solving (better known by its Russian acronym of “TRIZ”). This is a comprehensive system for analyzing and implementing inventive solutions to problems of nearly every imaginable type and scale. Altschuller was willing to share this and instruct anyone who was willing to participate in studying TRIZ. It is still widely used across the modern world. The author masterfully breaks down and clearly explains its essential components.

The true gem in the entire book is how Altshuller, while imprisoned in a brutal jail in Stalinist Russia, used only his mind to devise an ingenious solution to outwit his relentless interrogators. No spoilers here, but it is an emotional triumph that captures the heart and spirit of this remarkable man. Altshuller’s life and influence in generating thousands of inventions reads as though it might make for a dramatic biopic.

Also threaded and detailed throughout the book are the current bounty of easily accessible technological tools available to inventors. First, the web holds a virtual quantum of nearly limitless data that can be researched, processed, shared, crowdsourced (on sites such as InnoCentive) and crowdfunded (on sites such as Kickstarter and Indigogo), in search of medical advances, among many other fields.¹ Second, 3D printing² can be used to quickly and inexpensively fabricate and work on enhancing prototypes of inventions. As a result of this surfeit of resources, the lengthy timelines and prohibitive cost curves that previously discouraged and delayed inventors have now been significantly reduced.

Impossibility is Only Temporary

I live in a neighborhood where it is nearly impossible to park a car. An open parking space has a half-life on the street of about .000001 nano-seconds before it is taken. This situation often reminds me of a suggestion my father also made to me when I was very young. He told me that if I really wanted to solve an important problem when I grew up, I should try to invent a car that, at the press of a button, would fold up into the size and shape of a briefcase that could be easily carried away. At the time, I thought it was impossible and immediately put the, well, brakes on this idea.

Nonetheless, as Inventology expressly and persuasively makes its own brief case, true inventors see impossibility as merely a temporary condition that, with enough imagination and determination, can be overcome. For budding Edisons and creative problem solvers everywhere, this book adds a whole new meaning to the imperative that nothing is truly impossible if you try hard enough and long enough to solve it. This indefatigable spirit permeates all 223 pages of this wonderfully enjoyable, inspirational and informative book.

Inventing your own reason to read it should be easy.

For a dozen very timely examples of inventors and their inventions further typifying much of the content and spirit of Inventology, I highly recommend reading a new feature and viewing its accompanying video posted on on April 26, 2016, entitled These Top Twelve Inventions Could One Day Change the World, by Mike Murphy. It covers the finalists in the 2016 European Inventors Award competition currently being run by the European Patent Office.

1.  For example, last week’s Only Human podcast on NPR included a report on how a woman with Type 1 (T1) diabetes, along with the assistance of her husband, had hacked together an artificial pancreas (called a “closed loop” system), and then shared the technical specs online with other T1s in the Seattle area. I highly recommend listening to this podcast entitled The Robot Vacuum Ate My Pancreas in its entirety.

Does 3D Printing Pose a Challenge to the Patent System?

Whenever Captain Picard ordered up some of his favorite brew, “Earl Grey tea, hot”, from the Enterprise’s replicator, it materialized right there within seconds. What seemed like pure science fiction back when Star Trek: The Next Generation was first on the air (1987 – 1994), we know today to be a very real, innovative and thriving technology called 3D printing. So it seems that Jean-Luc literally and figuratively excelled at reading the tea leaves.

These five Subway Fold posts have recently covered just a small sampling of the multitude of applications this technology has found in both the arts and sciences. (See also #3dprinting for the very latest trends and developments.)

Let us then, well, “Engage!” a related legal issue about 3D printing: Does it violate US federal copyright law in certain circumstances? A fascinating analysis of this appeared in an article on posted January 6, 2016 on entitled How 3-D Printing Threatens Our Patent System by Timothy Holbrook. I highly recommend reading this in its entirety. I will summarize and annotate it, and then pose some of my own non-3D questions.

Easily Downloadable and Sharable Objects

Today, anyone using a range of relatively inexpensive consumer 3D printers and a Web connection can essentially “download a physical object”. All they need to do is access a computer-aided design (CAD) file online and run it on their computer connected to their 3D printer. The CAD file provides the highly detailed and technical instructions needed for the 3D printer to fabricate the item. As seen in the photo above, this technology has the versatility to produce some very complex and intricate designs, dimensions and textures.

Since the CAD files are digital, just like music and movie files, they can be freely shared online. This makes it likely that just as music and entertainment companies were threatened by file-sharing networks, so too is it possible that 3D printing will result in directly challenging the patent system. However, this current legal framework “is even more ill-equipped” to manage this threat. Consequently, 3D printing technology may well conflict with “a key component of our innovation system”.*

The US federal government (through the US Patent and Trademark office – USPTO), issues patents for inventions they determine are “nontrivial advances in state of the art”. These documents award their holders the exclusive right to commercialize, manufacture, use, sell or import the invention, while preventing other from doing so.

Infringements, Infringers and Economic Values

Nonetheless, if 3D printing enables parties other than the patent holder to “evade the patent”, its value and incentives are diminished. Once someone else employs a 3D printer to produce an object covered by a particular patent, they have infringed on the holder’s legal rights to their invention.

In order for the patent holder to bring a case against a possible infringer, they would need to have knowledge that someone else is actually doing this. Today this would be quite difficult because 3D printers are so readily available to consumers and businesses. Alternatively, the patent laws allow the patent holder to pursue an action against anyone facilitating the means to commit the infringement. This means that manufacturers, vendors and other suppliers of CAD and 3D technologies could be potential defendants.

US copyright laws likewise prohibit the “inducement of infringement”. For example, while Grokster did not actually produce the music on its file-sharing network, it did facilitate the easy exchange of pirated music files. The music industry sued them for this activity and their operations were eventually shut down. (See also this August 31, 2015 Subway Fold post entitled Book Review of “How Music Got Free” about a recent book covering the history and consequences of music file sharing.)

This approach could also possibly be applied to 3D printing but based instead upon the patent laws. However, a significant impediment of this requires “actual knowledge of the relevant patent”. While nearly everyone knows that music is copyrighted, everyone is not nearly as aware that devices are covered by patents. 3D printers alone are covered by numerous patents that infringers are highly unlikely to know about much less abide. Moreover, how could a potentially aggrieved patent holder know about all of the infringers and infringements, especially since files can be so easily distributed online?

The author of this piece, Timothy Holbrook, a law professor at Emory University School of Law, and Professor Lucas Osborn from Campbell University School of Law, believe that the courts should focus on the CAD files to stem this problem. They frame the issue such that if the infringing object can so easily be produced with 3D printing then “should the CAD files themselves be viewed as digital patent infringement, similar to copyright law?” Furthermore, the CAD files have their own value and, when they are sold and used to 3D print an item, then such seller is benefiting from the “economic value of the invention”. The professors also believe there is no infringement if a party merely possesses a CAD file and is not selling it.

Neither Congress nor the courts have indicated whether and how they might deal with these issues.

My Questions

  • Would blockchain technology’s online ledger system provide patent holders with adequate protection against infringement? Because of the economic value of CAD files, perhaps under such an arrangement could they be written to the blockchain and then have Bitcoin transferred to the patent holder every time the file is downloaded.  (See the August 21, 2015 Subway Fold post entitled Two Startups’ Note-Worthy Efforts to Adapt Blockchain Technology for the Music Industry which covered an innovative approach now being explored for copyrights and royalties in the music industry)
  • Would the digital watermarking of CAD files be a sufficient deterrent to protect against file-sharing and potentially infringing 3D printing?
  • What new opportunities might exist for entrepreneurs, developers and consultants to help inventors protect and monitor their patents with regard to 3D printing?
  • Might some inventors be willing to share the CAD files of their inventions on an open source basis online as an alternative that may improve their work while possibly avoiding any costly litigation?

If this ends up in litigation, the lawyers will add an entirely new meaning to their object-ions.

Printable, Temporary Tattoo-like Medical Sensors are Under Development

pulse-trace-163708_640There is a new high-energy action and suspense drama on NBC this year called Blindspot. The first episode began when a woman in left in a luggage bag in the middle of Times Square in New York with tattoos completely covering her and absolutely no memory of who she is or how she got there. She is taken in by the FBI who starts to analyze her tattoos and see if they can figure out who she was before her memory was intentionally destroyed. It turns out that the tattoos are puzzles that, once solved, start to lead a team of agents assigned to her to a series of dangerous criminal operations.

“Jane” as they call her, is quickly made a part of this FBI team because, without knowing why, she immediately exhibits professional level fighting and weapons skills. She is also highly motivated to find out her real identity and is starting to experience brief memory flashbacks. All sorts of subplots and machinations have begun to sprout up regarding her true identity and how she ended up in this dilemma.

So far, the show is doing well in the ratings. Imho, after four episodes it’s off to a compelling and creative start. I plan to keep watching it. (The only minor thing I don’t like about it is the way the production team is using the shaky cam so much it’s making me feel a bit seasick at times.)

The lead actress, Jamie Alexander, who plays Jane, is actually wearing just temporary tattoos on the show. While these cryptic designs are the main device to propel the fictional plots forward in each episode, back in the non-fictional real world temporary tattoo-like devices are also currently being tested by researchers as medical sensors to gather patients’ biological data. This news adds a whole new meaning to the notion of medical application.

This advancement was reported in a most interesting article on, posted on October 8, 2015 entitled Tiny, Tattoo-Like Wearables Could Monitor Your Health, by Heather Hansman. I will summarize and annotate it in an effort to provide a, well, ink-ling about this story, and then pose some of my own questions.

Research and Development

This project, in a field called bio-integrated electronics, is being conducted at the University of Texas at Austin’s Cockrell School of Engineering. The research team is being led by Professor Nanshu Lu (who received her Ph.D. from Harvard).  Her team’s experimental patch is currently being applied to test heart rates and blood oxygen levels.

When Dr. Lu and her team were investigating the possibility of creating these “tattoo-like wearables”, their main concern was the manufacturing process, not the sensors themselves because there were many already available. Instead, they focused upon creating these devices to be both disposable and inexpensive. Prior attempts elsewhere had proven to be more “expensive and time-consuming”.

This led them to pursue the use of  3D printing . (These four Subway Fold posts cover other applications of this technology.) They devised a means to print out “patterns on a sheet of metal instead of forming the electronics in a mold”. They easily found the type of metal material for this purpose in a hardware store. Essentially, the patterns were cut into it rather than removed from it. Next, this electronic component was “transfer printed onto medical tape or tattoo adhesive”. Altogether, it is about the size of a credit card. (There is a picture of one at the top of the article on linked above.)

The entire printing process takes about 20 minutes and can be done without the use of a dedicated lab. Dr. Lu is working to get the cost of each patch down to around $1.

Current Objectives

The teams further objective is to “integrate multiple sensors and antenna” into the patches in order to capture vital signs and wirelessly transmit them to doctors’ and patient’s computing devices.  They can be used to measure a patient’s:

One of the remaining issues to mass producing the patches is making them wireless using Bluetooth or near field communication (NFC) technology. At this point, chip producers have not made any commitments to make such chips small enough. Nonetheless, Dr. Lu and her team are working on creating their own chip which they expect will be about the size of a coin.

My Questions

  • Could this sensor be adapted to measure blood glucose levels? (See a similar line of research and development covered in the June 27, 2015 Subway Fold post entitled Medical Researchers are Developing a “Smart Insulin Patch”.)
  • Could this sensor be adapted to improve upon the traditional patch test for allergies?
  • Could this sensor be adapted for usage in non-vital sign data for biofeedback therapies?
  • Would adding some artwork to these patches make them aesthetically more pleasing and thus perhaps more acceptable to patients?
  • Could this sensor be further developed to capture multiple types of medical data?
  • Are these sensors being secured in such a manner to protect the patients’ privacy and from any possible tampering?
  • Could the production team of Blindspot please take it easy already with the shaky cam?

Prints Charming: A New App Combines Music With 3D Printing

"Totem", Image by Brooke Novak

“Totem”, Image by Brooke Novak

What does a song actually look like in 3D? Everyone knows that music has always been evocative of all kinds of people, memories, emotions and sensations. In a Subway Fold post back on November 30, 2014, we first looked at Music Visualizations and Visualizations About Music. But can a representation of a tune now be taken further and transformed into a tangible object?

Yes, and it looks pretty darn cool. A fascinating article was posted on on July 15, 2015, entitled What Songs Look Like as 3-D Printed Sculptures by Liz Stinson, about a new Kickstarter campaign to raise funding for the NYC startup called Reify working on this. I will sum up, annotate and try to sculpt a few questions of my own.

Reify’s technology uses sound waves in conjunction with 3D printing¹ to shape a physical “totem” or object of it. (The Wired article and the Reify website contain pictures of samples.) Then an augmented reality² app in a mobile device will provide an on-screen visual experience accompanying the song when the camera is pointed towards it. This page on their website contains a video of a demo of their system.

The firm is led by Allison Wood and Kei Gowda. Ms. Wood founded it in order to study “digital synesthesia”. (Synthesia is a rare condition where people can use multiple senses in unusual combinations to, for example, “hear” colors, and was previously covered in the Subway Fold post about music visualization linked to above.) She began to explore how to “translate music’s ephemeral nature” into a genuine object and came up with the concept of using a totem.

Designing each totem is an individualized process. It starts with analyzing a song’s “structure, rhythm, amplitude, and more” by playing it through the Echo Nest API.³ In turn, the results generated correspond to measurements including “height, weight and mass”. The tempo and genre of a song also have a direct influence on the shaping of the totem. As well, the musical artists themselves have significant input into the final form.

The mobile app comes into play when it is used to “read” the totem and interpret its form “like a stylus on a record player or a laser on a CD”. The result is, while the music playing, the augmented reality component of the app captures and then generates an animated visualization incorporating the totem on-screen.  The process is vividly shown in the demo video linked above.

Reify’s work can also be likened to a form of information design in the form of data visualization4. According to Ms. Wood, the process involves “translating data from one form into another”.

My questions are as follows:

  • Is Reify working with, or considering working with, Microsoft on its pending HoloLens augmented reality system and/or companies such as Oculus, Samsung and Google on their virtual reality platforms as covered in the posts linked to in Footnote 2 below?
  • How might Reify’s system be integrated into the marketing strategies of musicians? For example, perhaps printing up a number of totems for a band and then distributing them at concerts.
  • Would long-established musicians and performers possibly use Reify to create totems of some their classics? For instance, what might a totem and augmented reality visualization for Springsteen’s anthem, Born to Run, look like?

Medical Researchers are Developing a “Smart Insulin Patch”

“Spinning Top”, Image by Creativity103

In an innovative joint project at the University of North Carolina and at North Carolina State University, medical researchers are currently developing a “smart insulin patch” that can both measure blood glucose levels and then administer insulin to regulate it as needed for people with Type 1 diabetes. This is yet another approach at the core of much academic and commercial research and development at creating a “closed loop” system that senses and responds to changes in blood sugar.

Other ongoing research in this field is attempting to integrate continuous glucose sensors with insulin pumps, both of which are available on the market but not yet working together in a viable product with regulatory approval. Both of these approaches are efforts to create a biomedical system that can act as a fully functioning artificial pancreas for people with Type 1 diabetes.

The ongoing work on the smart insulin patch was covered in a fascinating article in the June 22, 2015 edition of The Washington Post entitled The ‘Smart’ Insulin Patch That Might One Day Replace Injections for Diabetic Patients by Brady Dennis. I will summarize, annotate and add a few questions of my own. (Two other recent Subway Fold posts on  October 3, 2014 and June 16, 2015, clickable here and here, respectively, have covered one project to upload glucose monitoring data to the mobile devices of friends and relatives, and another by a medical device manufacturer using social media to reach out to people using insulin pumps.)

This new smart insulin patch is a square shape as small as a penny and is word on the skin. One side of it contains numerous tiny “microneedles” that the face the skin and contain “both insulin and a glucose-sensing enzyme”. Thus, when an increase in blood glucose is detected, the patch can release insulin into the patient’s system “quickly and painlessly”. As a result, the necessity for the delivering insulin by traditional means of a syringe or insulin pump is eliminated.

To date, the development team has only tested the patch on mice. Early test results, published here in The Proceedings of the National Academy of Science (subscription required), showed that the patch worked on the test animals starting within 30 minutes of its application and then lasting for up to nine hours.

Dr. John Buse, one of the co-authors and the director of the UNC Diabetes Center, finds this “exciting”, but he also believes it will take years to determine if this will work in humans. A very informative and detailed news release with photos of the patch and the microneedles, entitled Smart Insulin Patch Could Replace Painful Injections for Diabetes, has recently posted on the UNC Diabetes Center website.

Using current technology requires people with Type 1 diabetes to check their blood glucose levels a number of times each day and then corresponding regulate their insulin to balance the effects of these up and down readings. Other researchers have endeavored to “closed the loop” between insulin pumps and continuous glucose monitors, but these systems still require close attention and adjustments by the patient

The smart insulin patch, if proven safe and viable, could one day dramatically change protocols for the care of Type 1 diabetes. It is an attempt to more directly emulate the human body’s own insulin regulatory system. As well, the microneedles in the patch are designed to be far less invasive and nearly painless than today’s use of injections, pumps and sensors, all of which require larger needles to pierce the skin. It is designed to directly “tap into the blood flowing through the capillaries” in order to become activated.

The researcher team has also found that they could “fine tune the patch” to attain blood glucose levels within an acceptable range. As a result, they are hopeful that, in the future, the patch could be adjusted to each individual patient’s system (including, among other things, weight and insulin sensitivity), and the duration of the patch’s effectiveness could be extended to several days.

My questions are as follows:

  • How exactly will the patch be personalized to meet the biological needs of each user? How will patients manage and regulate this from patch to patch? Is the goal to calibrate a single patch for the user or a series of patches as the user’s needs and environment changes?
  • Can the patches be customized and fabricated using today’s commercial 3D printing technology?
  • Will blood glucose levels still need to be checked regularly using current methods in order to assess and align the patch’s effectiveness and accuracy?
  • Can the patch’s data on blood glucose levels and insulin dosages be uploaded onto mobile devices in order to be monitored by the patient’s health professionals and family members?
  • Might the patch be used in conjunction with or even integrated into the Apple Watch as a medical app?
  • Can other medications that a person with diabetes is taking also be administered, monitored and regulated with the patch, perhaps making it even “smarter”?

Hyve-3D: A New 3D Immersive and Collaborative Design System

Collaborative tools have certainly come a long way since drawing on restaurant napkins and the backs of envelopes. Sure, these methods are still used today, but for a quantum leap into the future of idea sharing I highly recommend a article that appeared on an August 10, 2014 entitled Spectacular 3-D Sketching System Revolutionizes Design Interaction and Collaboration. This report covers an extraordinary new system called Hyve -3D that was developed at the University of Montreal. On the day this story was published, this system was presented at the SIGGRAPH 2014 Conference.

As described in this report, Hyve-3D (an acronym for “Hybrid virtual Environment 3D”), is a full immersive space where collaborators can create, shape and test new designs for products such as cars and many others. Through a series of input tools such as tablets, designs can be manipulated in a multitude of ways from this highly in-depth environment.

The U of Montreal is current pursuing ways to commercialize this technology, promoting its cost-effectiveness and relative simplicty in comparison to other systems like this currently on the market.

The eye-popping (albeit 2D), accompanying photos show how this works in car design. Many other field are anticipated such as, among others, architecture, medicine and game design. The Hyve-3D website contains more photos of the system in action. Many other field are anticipated such as, among others, architecture, medicine and game design.

This looks to me like the Holodeck some to life where the possibilities can barely be imagined yet. As I recall from Star Trek: Next Gen, there were several episodes where Geordi use the Holodeck to design and configure technological solutions to problems confronting The Enterprise.

I suspect that 3D design collaboration will find many unanticipated uses. Moreover, when combined with other leading edge technologies and materials science, designers will only be limited by their imaginations. For instance, if a 3D printing system were added to Hyve-3D, medical devices could be customized for individual patients needs. The current state of research in this nascent area was covered in a remarkable story also posted on on August 21, 2014 entitled Researchers Use 3D Printers to Create Custom Medical Implants.
