I agree Rob, I really like Flow-Rite's innovation and careful consideration of both environmental factors and seeking ways to error proof connections. The Texas sun is brutal as well - I am wondering how long one can expect the UV protection to hold up and what the specs are for that type of testing...we have UV protected furniture grade pvc pipe for some of our horse obstacles to protect against degradation but extended exposure will eventually have some effect. Of course horse obstacles aren't made to withstand acid so I am guessing these couplers are pretty tough in comparison.
I also really like their ease of use - it is so nice to be able to carry out a task without having to wrestle with the connectors first!
Probably so, Rob. The nice thing about our obstacles is that they are portable - they are easy to put up and break down in five minutes or less. If riders store them in their duffle bag out of the sun after using them - they should last for years. I think anything left baking in this heatwave will eventually have an effect. Same problem leaving them out in cold weather - pvc is known to get brittle.
Good point on the cold weather, Nancy. It could be that the repetitive swing from hot exposure to cold exposure breaks down the material. So UV resistance may not be enough. In my New Mexico backyard, plastics don't last long. While the temperature may only be 95, the sun beating on the plastic goes to a much higher temp.
I was just in Clovis a couple of weeks ago, Rob. It sure was nice - much cooler during the day and especially in the evenings than Texas at the same temperature. I think Texas humidity is a factor as well. Just goes to show that when you are designing for outdoor environments, there are all kinds of variables that need to be considered! Location, location, location!
Yes, Nancy, location is everything. a couple months ago there was a discussion about problems with a European car that was not holding up in the desert Southwest. While the car maker was happy to sell cars here, they were not testing their cars for our climate.
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.
