Somewhere between the research insight and the design criteria, there often seems to be a gap.
Case in point: the icemaker in my (and likely your) freezer.
The consumer wish: ice drawer is never empty
The design specs: ice drawer is always full
Annoying reality: ice drawer is overflowing and jams up unless you shut the switch off.
But we're not supposed to need the switch, so it is hidden behind a secret panel that you have to contort to reach.
What can I say, the work continues!
