Whilst mopping the floors today I was struck by how brilliant the universal joint is in my mop - it gets the mop head into any horizontal or vertical angle seamlessly and with ease. Just makes the whole experience of floor cleaning so painless.
So I thought I'd start this thread to recognise other similarly simple, elegant pieces of physical (not digital) engineering that make life easier without any fuss.
No rules, just a bit of fun. Interested to see what others come up with
As an aside - this is what AI tells me about the universal joint :
The invention of the universal joint is usually credited to Gerolamo Cardano (1501–1576), an Italian mathematician, engineer, and polymath.
He described the idea in the 16th century as a way to transmit rotary motion between shafts that are not in a straight line. Because of this, the universal joint is also sometimes called the Cardan joint.
Later, Robert Hooke, a 17th-century English scientist and engineer, developed a practical and improved version of the design. For that reason, the mechanism is also sometimes called a Hooke joint in his honor.
