Firstly you can have extra components (like the temperature sensors in this Anker supply) that monitor other components, and will shut down the power supply in case of an anomalous condition. Secondly for most circuits, most of the time, you can simply leave out components and the circuit will continue to work, at least on the happy path. For example take a typical PC motherboard, snip off some of the capacitors, and chances are that it'll still work. Big Clive has examples of very cost-reduced circuits where components are simply not mounted - there are even pads on the PCB for them, they appear in the reference design, but the manufacturer didn't include them, and the device will appear to work until it suddenly doesn't.

- mystified5016 1y agoYou clearly have no idea what kind of engineering goes into something like this. All of your arguments are pointless and uninformed. You have no idea at all what you're talking about.
- amelius 1y agoLet me just quote the guy from the video: "An interesting design, but bloody complex. With so many components the probability of some failing is adding up." And using less components so fewer things can break is actually a thing in engineering contexts.
- hnlmorg 1y agoThe GP literally provided you with examples of where additional components can provide resilience while still allowing the circuit to function should they fail. And yet you still reply with the reductive argument that there is some magical one-to-one correlation between component count and probability of failure.
- ashoeafoot 1y agoThen again the expensive equipments do not survive the error conditions (like gridspikes and blackouts either). You either guard at the gate or your fortress blows up with suboptimal results either way. Single point of failure filter design it is for economic reasons ?
