๐Ÿ’Ž On the merits of borrowing a standard idea from another field and applying it to your own (baby buggies and fighter planes)

Inventor Owen Maclaren created the first collapsible baby buggy by utilizing the system designed for the folding undercarriages of Spitfire fighter planes from World War II, while James Dyson used the cyclone systems used to suck up sawdust in sawmills and applied it to the home vacuum (see also Fix Your Frustrations, page 96). Both revolutionized previously entrenched designs. A spiral ramp might be fairly standard in an inner-city car park, but it is highly remarkable as an interior walkway of a public art gallery. If you find a current system disappointing or inadequate, try borrowing one from another field.
