What are the characteristics or a good design and a bad design?
Integral said:One bullet item missed in that link.
Design for maintainability. If a design has any moving parts it is going to break, unless the item is a consumable it will need to be repaired. Ease and cost of maintenance is something that is frequently overlooked by engineers working under a deadline.
Nothing like a high failure part that requires major disassembly to access. This type of engineering mistake causes increased down time and repair costs. If the design is part of a manufacturing process you will hear about it.
Having replaced the water pump in a Ford Probe (V6) last summer, I have first hand experience with that.BobG said:Someone should teach that to Ford. They seem to start with the engine component most likely to fail, then hang the rest of the engine from the part you're most likely to replace. And if it's not feasible to hang the entire engine from that part, weld a fuel line or other almost impossible to remove component to it.
