The need for self-defense prompted students to come up with a non-standard solution
In the event of a threat, a mobile phone turns… into pepper spray. An unexpected solution was proposed and implemented by students of the Novosibirsk State Technical University NETI.
As reported at NSTU, pepper spray integrated into a mobile phone case became an innovative project of second-year students of the Faculty of Radio Engineering and Electronics Pavel Fatyanov and Evgeniy Zapesotsky. They built a container with pepper filling into the body of a regular case. It has a dispenser with a sprayer.
It is curious that the idea of combining objects with such different purposes was suggested to Evgeniy by the decor of his mobile phone case, depicting a spilled liquid. “So the idea arose to modernize the case by integrating a pepper spray into it,” shared Zapesotsky.
The prototype was tested in October last year and proved its effectiveness. During the experiment, it was found that with a canister capacity of 25 milliliters, the device allows you to make up to 50 presses. Spraying distance is 1 meter.
This self-defense device easily fits into the smallest women's handbag.
The developers plan to modernize the system, that is, to introduce a protective rotary mechanism of the spray gun, eliminating accidental use of self-defense equipment, as well as improve the ergonomics of the case itself.
Students presented their invention to the university student project competition, where they took 1st place in the “Design Project” category.
