"I'm confused. Motorcycles have had helmet locks for ages, like this. Just hook the D-ring from the chin strap through the U-bolt and click it shut. Use a key to pop it back out again."

"I think that might play a role. I'd be willing to bet it's just as much a push from clever packaging techniques using magnets as hidden clasps. My own laptop has several rare earth magnets in it despite using a SSD. They are placed along the edges and allow it to snap shut when closed. I think the crafting/tinkering/DIY world is driving a good amount of demand for hidden closure mechanics as well."

"Found it! They were TFal pans."

"My parents had a set of pans with detachable handles like that when I was a kid. The locking mechanisms rusted, jammed up, lost their grip strength, popped open when not held by hand, scratched up the paint on the outside of the pan, and ultimately went in the garbage."

"This is the same idea as what I use to clean the inside of my car's windshield: https://windshieldwow.com/. I recommend getting the screw-in pole adapter."

"I don't think those studio shots are showing a more vibrant paint scheme. I think that's just a bright orange light shining on the beige hook. Look at the color on the interior of the hairpin-shaped piece."

"I really thought this was going to go another direction. The way I see it, the only reason this design is desirable is because of Jack Daniel's brand equity. If they had spoofed some other brand, it wouldn't be as funny or as profitable."

"Nice!"

"It's a cam-action door latch. Your clip shows a much prettier version of the same mechanism on the back of semi-trailers."

"Sorry, editing error: putting a screen on the outside negates the protection advantage as there is still a screen to protect, and it ignores the fact that a smaller phone that doesn't fold would achieve the same result without the risk of the hinge failures we've seen in the past."

"I think this design does a good job of solving a manufacturer's problem of not having a phone design that fully takes advantage of foldable screen technology, but I don't think it solves anything for consumers. Having a phone that folds gives you two advantages: 1. it makes the phone smaller, and 2. it protects the [interior] screen. Having a screen on the outside negates the first one. Putting a screen on the outside negates the second one, and ignores that there are already phones that don't require opening.I think this will sell quickly to early adopters looking to impress people, but never gain real popularity."

"You forgot the added bonus that if you don't strike true, there's a chance you could slip left or right and impale a portion of your hand!"
