The maintenance story reminds me of an episode of the cartoon Animaniacs in which two of the characters are trapped in an elevator.  They try to contact the maintenance department over the intercom, and overhear the supervisor telling one of his employees: "Hit it with the hammer, Big Ed.  No, the hammer... that's a wrench, that long thingy's a hammer..."

Later, after being trapped in the elevator for ten hours, the characters try to contact the maintenance department again.

"Are you still in there?" the maintenance supervisor replies. "It was our indication that you got out."

"Really?" the character says. "What gave you that indication?"

"That's just an indication we had," says the supervisor.

Airlines seem to have put their seating R&D dollars into improving the business and first-class sections on international flights, where seats transform into beds of a sort. Econmony class seat design does seem to have been static for some time. There has been, however, some improvement in leg room for a price to the customer. With the increasing prominence of narrow-body regional jets, it seems unlikely that economy-class seats will get wider. There seem to be simply too many constraints from available space and revenue to allow for much improvement.

Thanks Henry. Yes, I understand the economics of space for the back of the plane. And the space has grown smaller over my decades flying. The basic design of tray tables, arm rests, seatbelts, etc. has also been static for decades. I would guess the airlines are simply satisfied with these design elements.

The airlines may be satisfied with the design of the interior elements of their planes, but of course that does not mean that there is not room for improvement. The main selling point for economy air travel seems to be ticket price. Passengers seem to give that much greater priority than amenities relating to seat comfort. My feeling is that until passengers in large numbers let it be known that they are not satisfied with what the flying experience is like, the airlines will not redesign it beyond changes that bring in more revenue, such as more leg room, etc.

Yes, Henry, I agree that ticket price is paramount for air travel consumers -- including myself. And I can't imagine travelers choosing on airline over another based on anything but price. So I guess that says it all. No reason to improve comfort.

Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
