InkJet "Human Eye" Design: Biomedical Possibilities?



Nozzles used in biological tissue printers could one day be modeled after
a design that ensures clog-free nozzles
We all have that moment after when we turn from the computer and stare at our printers, waiting for the countless things that could go wrong in the process of printing out a document.  Inkjet nozzles can especially be a culprit, as their
tendency to clog costs businesses and residents alike thousands of dollars a year in wasted ink, not to mention trips to the barber to fix spots of torn hair.

Jae Wan Kwon, associate professor at the College of Engineering at University of Missouri, has invented an inkjet nozzle with an ingenious method of staying unclogged while keeping solvent; mimicking the human eye. 

          The eye and an ink jet nozzle have a common problem: they must not be allowed to dry while, simultaneously, they must open. We used biomimicry, the imitation of nature, to solve human problems.

 A small drop of silicone covers the "eye" of the nozzle.  When the nozzle needs to work, instead of trying to create eyelids to blink away the thin silicone coating, Kwon used electric fields to move the droplet in and out of place.  It works on such a small scale yet is incredibly efficient.

The real potential for a design like this, however, could be the realm of medical technology, where the US's already innovative market could adopt a model like this for biomedical labs.  Kwon's already figured this out and inferred to redOrbit  that's the direction he'd like to take the device:

      
“For example, biological tissue printers, which may someday be capable of fabricating replacement organs, squirt out living cells to form biological      structures....Those cells are so expensive that researchers often find it cheaper to replace the nozzles rather than waste the cells. Clog-free nozzles would eliminate the costly replacements.”

It's fascinating how little changes in design for something as taken for granted as an inkjet could maybe lead to a major contribution to biotech, but that's the kind of semantic thinking that should be rewarded in the evolving landscape of American manufacturing. 

To see video of Kwon's design in action (you have to look closely to see the details at work) go here.

Automated Driving Getting Closer To a Reality

The EN-V electric self-driving pod car from GM

I'm not exactly a fan of utopian visions, and when leading engineers in the field of autonomous driving say it's feasible to create an environment where vehicles would spot each other and their surrounding objects accurately enough to drive around them, my first reaction, oddly, is to cringe.  Giving up control of my car? To "Hal"?  Iiiiii dunno.

But proponents of autonomous driving promise that the technology will not only give us less to worry about in our daily lives, but will save lives as well.  Charles J. Murray, Senior Technical Editor for Design News, recently covered the latest advancements in the effort to achieve such a reality.  He quotes developers who claim it is possible to save the 30 to 40,000 fatalities recorded each year due to vehicle accidents by achieving a zero-fatality expectation as we do for airliners.

Specifically, sensor manufacturers will play a key role in this. Existing GPS technology works well to plan out routes, but for vehicle systems to know more, the information is received too slow (y'know, cuz its coming from orbiting satellites?) to be able to update multiple changes to the environment going on all around it (traffic, pedestrians, etc).  This is where two kinds of sensors come into play: accelerometers and gyroscopes.  Changes in direction and speed are recorded by the sensors and paired with the GPS to give a wealth of information about driving conditions for the vehicle to navigate.

But on top of that, the data has to be sifted through and put together properly.  In addition to sensor tech, processors have to be fitted to compare the inertial data with the GPS and paint the picture for the vehicle to figure out how to self-navigate.  Gyroscopes, sensors, data processors; the automobile has all of a sudden become a playground for 21st century software companies, not to mention an opportunity to carve out a sector that can produce stable, longstanding jobs in the future.


Manufacturers, auto brands, government, everyone is going at a snail's pace to make sure these changes are gradually phased into existing infrastructure.   Nevertheless, the ball is already rolling.  General Motors recently introduced Chevy's En-V 2.0 prototype at Beijing's Auto Show this year, an electric self-driving vehicle clearly designed for urban settings.  Alex Padilla-D from Los Angeles  introduced a bill that would encourage Google, who already have multiple autonomous vehicles driving on their company property, as well as other companies to further develop the technology with the intent of introducing it to low-traffic urban settings in the near future.

Plastic-Like Glass Revolutionizes In How It’s Made


Corning's Willow Glass is light, felxible and
Made in the USA.
With all the new innovations and inventions happening out there today, it’s easy to overlook the comparatively underestimated but nonetheless crucial instances of making existing products or operations better.  Take plastic behemoth Corning Inc., whose announcement in early June of their new Willow Glass design drew praise not just for the invention, but for how the product will positively affect Corning’s bottom-line.  

 Looking more like a sheet of plastic than glass, the Willow Glass is extremely flexible, enabling it to wrap around a device or display rather than fit into a slot.  This feature alone already makes the product incredibly cost-efficient.  Willow Glass is 100 microns thick, about as thin as paper, and yet can still be used for hermetic sealing while still withstanding normal weathering.  Clearly Corning invested in this product with the intention of being used in future smartphone and similar products where touch-sensor technology comes into play. 

 The real innovation, according to division VP and program director Dr. Dipak Chowdury is how Corning’s Willow Glass can be made.  As Chowdury tells it, “Currently manufacturing in a sheet-to-sheet process, we expect Corning Willow Glass to eventually allow customers to switch to high-throughput, efficient roll-to-roll processing, a long-awaited industry milestone.”  Roll-to-roll processing means the glass can be continuously rolled out like newspapers in a printing press, an adjustment to the production line that is sure to revolutionize the industry.

It’s not exactly a development that’ll beat the Election in media time, but it’s a great example of real changes in manufacturing that, when they start to pile up, amount to real savings in costs and time.  You can see a video of how Willow Glass is made here.

HYBRID MOTORCYCLE U.S. MADE

Two wheel vehicle resists flipping over in case of an accident
For those of us who never considered the motorcycle as a budget alternative due to its unique characteristic of not being very “accident-friendly,” the day may have come where we can enjoy an efficient, two-wheel vehicle while still feeling safe.

Lit Motors, located in the Bay Area, is billing their motorcycle-car hybrid- the C-1- as a “rolling smartphone”, not only because of its innovative navigation systems, but also because it has a built-in gyroscopic stabilizing system designed to prevent the C-1 from tipping over, even in some collisions.


 
In addition to gyroscopic sensors, the C-1 is also equipped with all the latest “smartphone” software now being integrated into automotive vehicles like GPS traffic updates, real-time weather tracking, as well as H2V, H2C, and V2V connectivity. V2V especially gives the C-1 the ability to predict if a road situation may lead to an accident, and how the driver can avoid it.  And those sweet glowing hubs?  Not just for show, they’re the vehicle’s power source; in-wheel electric motors.

Although finally making the jump from preliminary design to prototype, Lit Motors is keeping further details of the C-1 under wraps until it makes its showroom debut in 2014.  You can catch a sneak peak of the C-1 in action, however, on a released promo ad here.

ROTOR CLIP CHINA: WINDOW ON AN EMERGING ECONOMY


There has been a lot written about China’s emergence as a world economic power. But it is difficult to fathom in mere words the scope of what is actually taking place on the ground there.

 RotorClip recently opened a sales office, just west of Shanghai. We will be exporting our retaining rings, wave springs and hose clamps to the many manufacturing operations that have sprung up there. Our office is located on the 15th floor of a high rise building in JH Plaza on Huqingping road, a busy street in this part of town. There are two views from our office windows that really tell the story of growth in China.

The first is a view (above) looking out to the right of our office window from the 15th floor. It shows fields in the back that were once farmland; the two story structures in the foreground were small attached shops with living quarters on top. The government has bought out the owners of the land and the shops and relocated them to other areas (usually in high rise apartments). They are now in the process of tearing down the structures.

The second (above) is a view looking out to the left of our office window. It shows the kind of building that is taking place on these vacated properties. They are putting up structures like these that will serve as apartment buildings, office buildings and factories.

Not sure how long they can keep this up, but it is certainly happening just about everywhere you go in Shanghai. It’s a city full of energy and enthusiasm, and we are happy to be a part of it.

THE TIPPING POINT


The year 2015 will mark the beginning of a “tipping point” where bringing the supply
chain closer to home will outweigh the previous cost advantages of producing
in China.
Building on their previous work last year, Boston Consulting Group released its most recent report confirming outsourcing losing its cost advantage for American companies.  Last August, BCG gave its first release of findings that wages in China- the chief motivator of off-shoring- were increasing by 15 to 20 percent annually.  At that rate, the labor-deficit in cost would shrink to 39 percent of an advantage for China by 2015; not a number most companies would bite on as a savvy move:

Wage and benefit increases of 15 to 20 percent per year at the average Chinese factory will slash China’s labor-cost advantage over low-cost states in the U.S., from 55 percent today to 39 percent in 2015, when adjusted for the higher productivity of U.S. workers. Because labor accounts for a small portion of a product’s manufacturing costs, the savings gained from outsourcing to China will drop to single digits for many products.

The previous report in October added to this with a more specific analysis of exactly what types of industry would be relocating jobs and business back stateside:

“In addition to transportation goods, electrical equipment/appliances, and furniture, the sectors most likely to return are plastics and rubber products, machinery, fabricated metal products, and computers/electronics.  Together, these seven industry groups could add $100 billion in output to the U.S. economy and lower the U.S. non-oil trade deficit by 20 to 35 percent, according to BCG.”

A recent article in The Economist lists a study that confirms the rising wages of Chinese labor dating from even two years ago:


China has the world’s largest manufacturing workforce: more than 112m people at the end of 2006, according to Erin Lett, formerly of America’s Bureau of Labour Statistics, and Judith Banister of the Conference Board, who include enterprises in China’s towns and villages…But it is not as cheap as it was. Workers’ compensation rose by more than 9% a year in dollar terms from 2002 to 2006, according to Ms Lett and Ms Banister, and by over 11% in the cities. A new study by Dennis Tao Yang of the Chinese University of Hong Kong, Vivian Chen of the Conference Board and Ryan Monarch of the University of Michigan suggests that Chinese workers, in the cities at least, are now as expensive as their Thai or Filipino peers.” –The next China, The Economist, July 29th, 2010


The resulting numbers prompt BCG to predict that the year 2015 will mark the beginning of a “tipping point” where cost advantages doing business in China will slow to the point that American companies will begin to reel supply chains back closer to home.

It’s probably wise to emphasize that this is what BCG projects could happen within the next few years.  The release is a cheery read and gives a good summary of not just the numbers but also to a general feeling that companies who have outsourced for the past couple decades now have a lengthy body of long-term data to review, and the overall profit margin for most of them isn’t as impressive as it was supposed to be.   There are two tracks of thought here: one is that cheap labor is worth spreading out your operations, the other is that immediacy of communication among the chain is paramount to your overall bottom line.  I suppose the former works when labor is so dirt cheap you can get people to build your product for a cot and a biscuit a day (I don’t know how your conscience holds up in that scenario, but that appears to be a moot point to everyone these days).  However, it’s my opinion that the latter has more sneaky value because of the overall cost efficiency of your whole business; geography counts for a whole lot when your entire mission is to assemble parts from various locations as well as possible.  That’s just an obvious bonus on every level of your business. 

You could also make a solid argument that the expense going overseas has always been there, and that it took the Recession for American manufacturing to really look at the actual numbers involved in how much a stretched supply chain actually costs.

All in all, the numbers could be heralded as good news to those who believe rising wages in China translate directly to a flood of jobs back to the States.  It is important to note, however, that off-shoring was a trend exacerbated from globalization and the global economy isn’t going away here.  China may have lost its luster from a labor perspective, but that does not at all in any way mean it is not a major player here to stay.  China’s heavy dependence on exports and sheer volume of available labor all but guarantees its position as a chief importer, to say nothing of the Chinese government’s manipulation of its currency.  Even if jobs do leave, they’re likely to end up in Mexico or Korea before coming back here.  The US is doing its best to stay competitive for the work, but if we want more domestic jobs, a strategy to create new work will be more realistically viable than trying to lure old ones back.

SME Education Foundation’s Excellent Example


SME provides "cool" manufacturing site for elementary students.

I’ve posted on here before lamenting the missed opportunities we’ve had the previous few decades to incorporate more incentives to educate a whole new generation of manufacturers.  There are certainly a lot of outside uncontrollable factors that went into the shifting global landscape.  Labor advantages, third-world modernization, take your pick; life does not happen in a vacuum, and that goes for the U.S. manufacturing industry as well.

 However, there are those of us who still believe that we wouldn’t be having the issues of unemployment and brain drain we have today (or at least as large a problem as they are today) had we not invested more in educating our youth the past twenty years. That’s why it’s rather refreshing for me to see the Science, Math, and Engineering Education Foundation, or SMEEF,  spread awareness to students at the elementary level about subjects relating to manufacturing, and doing it through their chief medium of communication nowadays:
 SME recently updated their website, Manufacturing Is Cool, a wonderfully interactive site targeting young students by featuring examples of science and engineering in their everyday life.  It’s broken down into categories like technology, food, entertainment and mechanics.  Each category not only explains how certain products are made, providing YouTube links to illustrate the factory process, but they also allow for students to explore the engineering process itself.

The language is a tad precious (the designers make the classic mistake of assuming hip kid lingo amounts to a lot of alliterations like “snacking solutions, distracting diversions, chatting contraptions”, etc.)  but the site’s concept is a brilliant example of how the internet should be used:  bridging areas of life and industry that on the surface look completely unrelated.  Students can learn how cell phone technology works, then jump with one click to a press release about NASA’s next Mars probe.

There’s a feature on Xerox’s history, as well as how Xerox’s digital printing process translates into successful mass publishing; a genius way to lure more literature-minded students to manufacturing (if this site had been around when I was in elementary school, my career choices might have turned out differently.  Of course the internet wasn’t a “thing” back then, so I probably would’ve just gone back into the living room and watched TV.  Ah, the ambitions of a suburban pre-teen in the 90’s…).  Additionally, the site features social media links, scholarship information, and sponsor links as well.

The site’s subtitle: “Be An Original Thinker!”  summarizes the forward-thinking approach of its designers.  Nowhere here are students lectured on what jobs they should do, or what careers they should be preparing for, or even that they should necessarily be preparing right now anyway.  Instead, SME’s site just tries to reveal the hidden connections in the everyday world, get students to see beyond the colorful shell of a smartphone and be aware of the different kinds of jobs and sectors that converge in order to make that smartphone function.  This way, students are introduced to knowledge concepts through the world around them, and as someone whose taught students before, trust me when I say this kind of approach is phenomenally more successful in results than pushing information on them in the form of traditional subjects, like “study this math lesson or you won’t pass this test we use to say whether you’re smart or not.”

So as the kids say, “Big Ups” to the SME Foundation for meeting students on their playing field with an original and clever educational site.  I encourage  everyone reading to hop onto the link provided (here it is again, in case you missed it, and you just don’t feel like going two paragraphs all the way back, poor thing) and lend them your attention.  You’ll be helping out a terrific educational effort.
