I find it very hard to believe: as soon as he mentioned removing small empty boxes the idea of a fan leapt to mind; I really can't imagine that none of the team already operating the factory thought of this solution.


The only problem IMO is it's not vary reliable without something to detect the fan is still working.


The alarms would start going off again when empty boxes reached the precision scales. Behold, an $8mil broken-fan detector.


Let's start making it more complicated again!

Wind meter on the other side of the conveyer belt and an air horn whenever it drops below a certain level...


Like someone said, two fans for live redundancy, little lengths of ribbon for visual failure indication.

I'd have thought a couple of fans checked once a day would provide less failures than are significant.

This doesn't seem like a reason not to propose the system, the alternate proposed solution would have similar failure modes too.


Two fans!
