Looking for Invention Inspiration

[TieXiongJi]

Hi All!

I am an engineer and martial artist. I have a few ideas for self defense equipment for professional use, but I would love to hear the problems you see while working in security, bouncing, defending yourself...
Please describe the situation where you may need some additional equipment, but couldn't find the right piece.

I am a problem solver and would like to solve your professional problems with specially designed equipment for your profession.
