in my former life I was a professional elctronics design engineer
mainly working in AC drives systems for robotic car assembly , so Ican comment on both the car design and the electronics!
(a) were professionals, you think we design anything some uneducated pleb can fix. hah think again
(b) we have $$$$ of diagnostics , special tools etc that allow us to get to the unservicable thingy, youre meant to buy them and then spend $$$$x2 on training, even then you;ll never fix it like my robots can.
(c) weve spent zillions on establishing a overpaid, poorly trained expensive dealer servicing and installation
network, you think we make it easy to install and fix ...pleaaaseeee,
(d) we know how to use the $$$$tooling to create good splices and what not, whadda need all the spaces between the connectors. see (c) as well.
(e) all the components fail about 1 month after the new model comes out, sure we could make the damm thing last forever, however that gets us fired
designs all spare parts
(g) since we wrote the software
we know all the funny
front panel button sequences that we dont document in the manual and that actually make the unit sit up and beg, what, we have to keep some mystery in it, see the bit about the risk of being fired. we like to be indespensible, hence unreadable manuals
, unexplained faults and wierd non-documented operation.
(h)our design work absolutly perfect in the design lab, after that all bets are off, anyway marketing
gets involved and everything they touch....
(i) since we test all our designs without any cases ( we call them enclosures). we have no idea how difficult it is to wire up with the final case installed, we have no problem wiring
to the PCB, anyway marketing designed the case, actually Jenny, 21 and just out of college designed it, shes completely clueless, but hey she brightens up the place.( and marketing keep putting her in the PR photo
shoots in a white coat and bs-ing about our new "advanced transderm reciprecating invertor technologytm").
(j) first level tech support ..hah, these guys couldnt tie there shoes properly, we train em..right see (g) above.
see folks all explained
