Complexity (Useability)

Thought-provoking article.  I've found that useability (and mis-use) is the area that also deserves special attention when designing certain types of devices.  Identifying the appropriate use cases for products tends to be straight-forward.  However, having the creativity to predict all of the mis-use cases that could possibly occur is challenging and takes an extra amount of time and mental imagination to really get it right up-front.

I think the statement, "Ironically, complexity is often added to a system to reduce common-mode failures" is true no matter what level of design you are at - from simple circuits to intricate systems - but at the system level the interactive nature of the subsystems can indeed cause some unexpected issues that are much more predictable in less complex designs. Interesting article with much food for thought...

Kevin, it makes perfect sense that complex systems require new forms of management as they become more complex -- especially in the realm of avoiding catostrophic failures. Nice review.

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.
