I don't know, Warren. If China is building to spec, the design flaw and lack of development test could be originating here. It seems to me that quality in design and development is being sacrificed in favor of a cheaper product. It seems we have lost the culture that used to exist when people stayed in their jobs for years and quality was highly valued despite cost. With the current economy and trends in manufacturing it seems to be getting harder to find a really well designed AND well tested product.
If we keep buying from China, et al, and we depend upon their good graces to insure all the safety mechanisms are in place (remember dog food and sheet rock?), we will all have to become engineers just to solve these problems. My wife would have panicked and not known what to do- as would 3/4ths of the men I know.
A world of engineers. Now that's the Thanksgiving table I want to be sitting around!
I have a lawn mower and a lawn vacuum, each with interlocks / safeties. The lawn mower has a safety bar that must be held or the engine will not start, or stops when released. The lawn vacuum has a similar safety bar for the drive = the drive engages with the bar, disengages when the bar is released. Were there similar safeties or interlocks on the Power Wagon ?
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
