Its funny, I know you're right.  But I was educated within an engineering culture where quality, reliability, and robustness were PRIMARY.  Then, after the product had passed lots of accelerated life testing, the second generation of the same design was cost reduced to improve the profit margin.  Our principles were: Quality first, because it would get the market.  Cost reduction second, because it would grow company profits.  Old-School thoughts, I guess. But good, sound practice because too many products today are absolute crap, right out of the box.

My guess is that if there was any form of design review done it was soley concerned with cost reduction. That is the way a whole lot of products are designed. Not all companies believe in delivering any level of quality. And that is a problem sometimes.

Simple reading of all of these excellent comments make you wonder if the ODM ever held a design review-?

EW, the correct way to use a threadlocker on an electrical connection is to apply it after the connection is torqued correctly, so that the metal-to-metal connections are made without threadlocker present. Then the material is applied to lock the joint frpm the outside. That is so that it will not get in the way of a good connection. But if it is a self-tapping scrw run into plastic then don't wate your time on thread locking materials.

The suggestion of adhesive on the screw head is good.  Using thread locker is problimatical - it is an insulator.  On some (probably not all) units the screw will be tight, but there will be no electrical contact.  Experience speaks.

LOOSE SCREW

Excellent post Dan.  It seems to me the loose screw rests with the designer of the device and the company he or she works for.  I think your post is indicative of our "throwaway society".  It certainly makes me wonder if anything is tested anymore.  Several years ago I purchased a "Western Flyer" wagon for our two oldest boys. (This indicates to you how long ago that was.) Western Flyer, I thought, was an excellent brand one that would stand the test of time much less our two eight and ten year old sons.  Good thing I had a drill.  None of the assembly holes aligned properly.  Western sent only the correct number of nuts and bolts--no more.  I spend a couple of hours re-drilling and enlarging holes just to complete the assembly.

Nice point AnandY, It is a possiblity. Some manufacturers unfortunately might design there products in a way that they might become desposable soon, and force the consumers to spend more on it. I mean, how many of them would bother fixing the collar?

That is funny and true at the same time. The consideration of the user end is very important for a good engineering design. Probably it might be suitable for some other animal, but considering the extra hyper nature of a dog, It is definetly a poor design.

All the other design flaws aside, I can pick out two that should never have been made. First off, it is poor decision making to only use a single screw and then use it without any thread locking compound. Secondly, if they had done any significant durability testing, they would have known that the screw would cause problems within a short time. Or maybe they knew all these but simply didn't care because if they did you wouldn't be adding them more dollars.
