The "Knowledge Forum" can make a difference in the contemporary world by encouraging design of machinery for maintenance at a level of modest competence.
The example I offer today is a dishwasher, which I was able to keep running for nearly eleven years, five years more than the manufacturer's warranty.
Today I am having to throw in the towel, because the failing component appears to be a relay on the control board, and I do not want to deal with it. I have designed a small circuit board, had it fabricated by an online service, and populated the boards with components, so I understand the process.
The request I am posting here is for designers of equipment to think about the customer who needs to keep a piece of equipment running when the convenience of the complex civilization we enjoy today is not readily available, for whatever reason.
While "The Knowledge" forum is populated by only a few people at present, it is never-the-less in a position to generate a new meme based upon the concept of "Design for the Apocalypse".
In the case of the dishwasher, if the relay controlling the heater element is a more vulnerable to failure than the rest of the board, then that component could be designed to fit in a socket able to maintain sufficient current flow. In the "good olden days" we built equipment with vacuum tubes that sat in sockets able to handle significant voltages and current flows.
I understand that the convenience of mass produced circuit board manufacturing lines is attractive to keep costs of equipment low. The design changes that would permit a longer service life would require a greater cost, so a related but IMPORTANT component of the meme change is to persuade customers to BUY equipment designed for the apocalypse.
May every member of The Knowledge forum grow financially, intellectually, socially and beyond.
