I was looking for more examples to support my earlier post on Edge Case Design and walking out of the car park this evening this occurred to me:
How do you design a door handle that works equally well for a child or a basketball player?
The typical horizontal bar that works for the average height person doesn’t work for either of those extremes particularly well (and actually is awkward for a lot of sort-of-average height folks), but imagine if you were to rotate the bar so it was mounted vertically and you can easily cater for the edge cases… and in doing so have a great solution that fits all of the 80% median part of the curve as well. No matter how tall you are simply push against the part of the bar that falls most comfortably to hand to open the door.
I am starting to think that there’s something in this Edge Case Design philosophy… can you think of other examples?
