Re: "Right Sized" Safety Solutions Affects Cost

Excellent point, Kenish. If the systems could be evaluated for risk reduction, false alarm occurrence and other operational performance, that would probably factor as the greatest cost indicator. That evaluation may be a tad difficult, though.

Buying the logic of safety

The concept of safety zones and limited area E-Stops would undoubtedly let production run more efficiently, but have you ever heard about an operator on one side of the line hitting an E-Stop when they saw an operator on the other side of the line get in trouble? It sounds a bit like the "It's not MY job" syndrom there. I can see the validity of having area stop buttons but for an emergency, unless the machine designer can predict exactly where and how accidents will happen, having a "MASTER Stop" makes a lot more sense.

Robotic Safety Zones

Robotic safety zones is an interesting technology area where there has been ongoing innovation. Robotic programmable safety systems are providing new technology that may enable reducing the footprint of robotic systems used in packaging applications, for example.  With that premium on floor space, this is a potentially key feature.  Plus, by implementing the safety solution within the framework of the robotic controller, these solutions are eliminating the need and cost of external safety devices such as light curtains, limit switches and other safety-related systems.

What you say, William, makes a lot of sense.  I would think that zone e-stops would only work if the work zones were obvious - say a particular machine that does not appear to be connected to the rest of the system would have its own stop.

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.
