Here's a great example of reinventing an everyday object: Sweden-based Frii Designs' Conda strap.
It's flexible and rope-like, but when you flip a switch that's attached to it, a segmented section of it turns rigid. This means that in its intended camera strap application, it can do triple duty as both a selfie stick and an ad hoc tripod:
So how does it work? I suspect the thicker portion contains ball-and-socket joints, with each of the balls having a hole, and a cord running through all of them, and that flipping the switch pulls the balls into tension with the joint. But that's just a guess.
The Conda has been successfully Kickstarted, and at press time there was 30 days left to pledge. Buy-in starts at €82 (USD $98) and they expect to start shipping in March 2021.
