Almost any product which was manufactured according to ISO9001 uses this approach. It includes almost all known electronics manufacturers.
I am intimately familiar with ISO9001, having once been a Divisional Quality Manager and having brought an organisation up to ISO9001 compliance no less than four times. I have authored entire Quality Management Systems (QMSs).
There is literally nothing in ISO9001 that describes, or requires, the ridiculous antics that you claim are commonplace.
I already provided you with example of device with no microcontroller - electric stove which consists of electric heater, power regulator and mains cable... It is failed just after 5 months due to failed power regulator. It is even hard to imagine how to make so simple thing with so small lifespan. But they do that...
Are you serious? That is ONE example! And I've provided one example of a motherboard that is still working fine after 12 years. Both are of no value because we need quantities: failure rates and lifespans are statistical phenomena.
I suspect in the case of your stove, one or more components were operating significantly outside their specifications, hence an early failure. What it does NOT demonstrate is that some engineer sat down and said "OK, how can I design this such that it fails after 5 months?".
You made two claims:
1/ Electronic devices can be made to fail after one year, with an accuracy of weeks or even days.
2/ Most devices are designed to fail after a year or less.
In support of item 1/ you described a frankly extraordinary process which would need to last several years, and which relies on finding electronic components with an almost inconceivably short lifespan (or short MTBF). I would remind you that the reliability of electronic components is specified in "FITs" - failures per
billion hours.
In support of item 2/ you quote one example: a stove which failed after 5 months. But most people's experience of electronic products is that they last much, much longer. Almost indefinitely unless they contain a battery.
In my house there is only one electronic product less than a year old - a new laptop. There are many products in my possession that are between 1 and 13 years old, and a handful that are a few decades old: the tablet I'm typing on, two remote controls, a mobile phone, a TV, two TV set-top-boxes, several electronic watches (some going back to the 1970s), two novelty electronic toys, eight or nine quartz clocks, several smart-home light bulbs, three laptop PCs, a desktop PC, numerous pieces of test equipment in my workshop, including an oscilloscope, a signal generator, two bench PSUs (which were made in the 1980s), two electronically controlled soldering stations, an electronically controlled lathe, five multimeters (although one is not really electronic). Also around are another TV, a surround sound system that is 16 years old, I think, a DVD player, three Bluetooth headphones, numerous wall wart power supplies.....
I'm wracking my brains to remember the failures I've had. The 13-year-old Sony hybrid works fine except that the bottom fifth of the screen no longer responds to touch, so there is that. I also recall a wall wart failing, but I've no idea how old it was - several years, I think. Like most people I am literally surrounded by electronic products, in my case all but one being over a year old, and a good number are decades old. They are all still working apart from those two I mentioned. Oh, I've remembered another: an LED light bulb that failed after about a month.
This is the reason why I think your second assertion - that "most" electronic devices are designed to last "a year, often less" - is simply nonsense. It is blatantly, obviously not true, and I think that seriously undermines your first claim as well.
Anyway, this thread is surely exhausted by now. Please feel free to have the last word - I'm sure you will want it.
