Red Point Measure Concept Device Has Pythagoras To Thank

By Andrew Liszewski

I usually try and avoid concept devices, but once in a while I come across a great idea that deserves some recognition. Such is the case with the Red Point Measure device, designed by Huang Qiaokun. It’s composed of two rotating arms with a laser on each end, and all you have to do is point the lasers towards the end points of whatever you’re trying to measure. Thanks to the Pythagorean theory, the distance between those two points can be easily calculated based on the angle of the device and how far away the object is. Since laser measuring devices already work in a similar fashion, I don’t think the Red Point Measure is that far off from being a feasible product.

    Would also need a built-in level so you can be sure the right laser is pointing to a spot the same height as the left.

    I'll try not to be a dorky math teacher, but it would use the law of cosines. The Pythagorean Theorem is a specific case of the law of cosines, and would only apply with a 90 degree angle.

  • Please feel free to be the dorky math teacher. It's the only way we'll all learn.
