SignalBallon

The SignalBallon, examines the problem of the current climate crisis and its consequences. This product aids people trapped in a flood situation and helps those stuck at home unable to escape.

Concept/

Problem

Targeted searches are particularly important in flood disasters because rescue workers have to find trapped victims quickly before it is too late.

The SignalBalloon was developed to enable effective and visible signaling in emergency situations. Flood disasters are increasing every year due to the worsening climate crisis. In such situations, emergency services are often overloaded and cannot always help victims quickly enough.

SignalBallon allows survivors to clearly mark their position without relying on electricity and it allows rescue workers to reach people more quickly and effectively.

When not in use, the signal balloon is attached to the outside wall of a house or apartment.

Red balloon floating in a blue sky above a modern building with cantilevered balconies.

As soon as the balloon needs to be used, the person in need of help pulls on the rip cord and thus triggers the mechanism that causes the balloon to rise.

As soon as the rip cord is pulled, the piston is fired into the helium cartridge by the spring and cuts it open.

This causes the helium to flow into the balloon, which blows open the outer shell (similar to an airbag). The balloon rises.

How it works

The inner mechanism uses technology from Helite, which could be potential future cooperation partners.
