The creator breaks down the problem with existing desk pad clamps and proposes using a vise grip mechanism as a more satisfying solution. He explains the two main design challenges: the length of the tool and the need for automatic tension adjustment for varying paper thicknesses. Using 3D printed models, LEGOs, and a disassembled vise grip, he demonstrates the mechanics of the toggle lock, shows a more compact prototype, and then presents the unsolved problem of adjustability, asking the audience for their ideas.

The reason that we're trying to bring a vice grip to a yes bad is that our current desk pad offering uses a very slow interaction to remove page of paper. The vice grip, one simple action and your clamp is totally released and sprung open. A meaningful improvement to the traditional clipboard as well that is, I think, less satisfying as an object to deal with. But there's two main issues. The worst, I think we've got a pretty good solution for, but the second one is a bit of an open question. I'm pretty interested to hear if you have ideas for how we could solve this in the best possible way. First problem is length of the vice grip. We wanna bring that closer without losing what makes it such a satisfying interaction. To do that, we need a slightly better understanding of what's going on here. As you are closing the jaws of the vice grip, any pressure pushes that pivot point further away. Best once it crosses that toggle point, it snaps into the better stable arrangement. Any pressure on the jaw suddenly actually locks it further closed. To release it, you have to pry that pivot point back above that imaginary center line by lifting up on this input lever until you rearrangement that can happen. Essentially, flipping the input lever and this coupling rank, the lever arm is now sweeping back towards you. Maybe we can better explain by hacking a part and reassembling a vice grip. Now put something there. It preserves that satisfying snap when it pushes into the second position, and it's way more compact. This leads us to the second problem. Ryan, you took this first rearranged vice grip idea and brought it into this first prototype. You can see it does the same motion over center to hold some worst it notes. It works fine for that amount of paper, but if I want to add more paper suddenly, oh, I will break that. The classic vice tier requires this adjustment screw on the back to change the clamping height. If I'm taking out pages, I don't wanna have to give it a quarter turn on the back to, like, make sure it still has tension. No we want a solution that requires no tuning, but can handle anywhere between one sheet of paper and a 100 sheets of paper All while maintaining that satisfying tactile feeling of a vice grip Anyways, how do we solve this problem? How do we solve this? How would you solve this?
