esocid's Journal: Engineers and technicians

For anyone out that who has worked on...anything...has it ever run across your mind, while you are cursing the engineers into oblivion, why in the hell did they design it like this? My frustration has come mainly from working on cars. I own a 1985 Oldsmobile Cutlass Supreme that has not given me much in the way of headaches. It did always confuse me as to why 1/2 of the bolts on it are metric and the other half american. The worst things I ever had to replace were the engine mounts. My most recent tirade of swear words came when replacing the upper control arm on my 1997 Ford Explorer (I'll forgo explaining all the reasons I hate this car for now) and was the 2nd time within a year I've replaced the thing. There are two large bolts that mount it to the frame, one of which was no sweat. The other was buried underneath fuel lines, brake lines, and 4 inches away from the frame when the bolt itself is longer than that. I had to force the steel lines out of the way and manage to tilt the bolt up and out all while having my hand dangerously crammed in some tiny space. It took about 3 hours to replace the part, the majority of which was spent on removing one bolt. Another example: I had to replace the third brake light above the rear window. First of all, I'd like to know why someone decided it would be a great idea to put a neon cathode tube with a ballast-transformer as a brake light. Second, why was this thing enclosed with rivets? To replace it you must drill out the rivets, removed the light assembly, bake it in the oven and use something to dissolve the glue they used to seal the assembly. You could simply replace the assembly for a mere $300+ or make yourself an LED array like I, and many others, did for about $10. Is it that engineers never think of maintenance when designing products, or is it that managers pressure them to do it to the lowest common denominator - cost efficiency? I have come across this with electronics, but with less frequency, and mostly with printers, but why are mechanical devices designed so difficultly to repair?
