The innovative project of Pavel Fatyanov and Yevgeny Zapesotsky, second year students of the Faculty of Radio Engineering and Electronics of Novosibirsk State Technical University of NETI, will allow them to respond promptly to danger in emergencies. The developers have introduced a pepper spray integrated into a mobile phone case. The container is built into the body of an ordinary case and has a dispenser with a sprayer.
"In the course "Project Activity Fundamentals", first of all, we are looking for an urgent problem that can be solved newly. Turning over the topics, we remembered one of them — self-defense in dangerous situations. At that moment, I was holding a phone with a case in my hands, the decor of which imitates a spilled liquid, and so the idea arose to modernize the case by embedding a pepper spray in it," Evgeny shared.
The prototype was tested in October 2023 and proved effective. During the experiment, it was found that with a canister capacity of 25 mL, the device allows up to 50 clicks. The spray distance is 1 m.
The advantage of the "pocket" security system is its efficiency and compactness. Thanks to the embedding of pepper spray in the case, the device easily fits into the smallest women's handbag, which provides quick and convenient access to the means of protection in any situation.
The inventors plan to improve the system by introducing a rotary protective mechanism for the spray gun and improving the ergonomics of the case. To finalize the prototype, the team needs financing in the amount of 50 thousand rubles.
According to the students, pepper spray in a mobile phone case is an innovative product that has no analogs in Russia or in the world.
At the competition of student projects of Novosibirsk State Technical University, the development took first place in the nomination "Design project".
