Smartphones need cases, coffee mugs need coasters, hunting knives need sheathes. It's weird to think about how many products are not designed with their own base or carrying case, and as it turns out, that's an opportunity for sharp-eyed product designers. Designing an object whose sole purpose is to protect or augment another object is something we never covered in design school, but apparently it's lucrative.
The latest case in point: The Staybowlizer silicone thingamajig you see above. Your standard mixing bowl is made out of stainless steel or glass, which has a tendency to slide on your standard commercial kitchen prep surface of stainless steel or wood.
The Staybowlizer provides a little "nest" to keep the bowl stable.
Set it with the wide side up and you can have it hold the bowl at an angle, making it easier for you to pitch in whatever you're chopping up...
...or turn the ring upside down and it turns into a huge suction cup, keeping your bowl firmly fixed in place so you can mix one-handed.
I know it might seem silly to a consumer, but having worked in restaurant kitchens I can see the value of this thing. And I like the suction cup action—I'm thinking about getting some for my two dogs' bowls, to stop them from sliding them all around the kitchen while they scarf down their chow.
