Solution Overview
Problem
Existing rescue systems for high-rise buildings during fires lack comprehensive protection and control, leading to increased risks of injury or death due to exposure to toxic gases, high temperatures, and improper descent mechanisms.
Innovation Solution
An intelligent life-saving system that includes a fire-proof coverall with oxygen supply, a high-temperature resistant sling, and an electromechanical device for intelligent fast descent. The system provides voice guidance, automatic detection of the rescuee's location, and intelligent control of descent speed to ensure safe landing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple escape backpack with rope is used, then the device is simple and easy to operate, but the rescuee lacks comprehensive protection against fire hazards and toxic gases
Solution Approach 1:
The patent implements a nested protective system where the coverall is worn underneath the helmet, and the oxygen supply device is integrated into the helmet structure. The coverall itself contains multiple functional layers including fire-resistant material, cushioning layer, and temperature insulation layer, creating a nested protective structure that addresses multiple protection requirements simultaneously.
Solution Approach 2:
The escape device is designed as a multi-functional integrated system where the helmet provides both oxygen supply and fire protection, the coverall provides both thermal insulation and cushioning, and the descent device incorporates both braking and signaling functions. This multi-functionality resolves the contradiction by combining multiple protective functions into a single operational system.
2Ease of operation
If a traditional rope is used for descent, then the rope is simple and easy to handle, but the rope is short (less than 80m) and can be burned to break when passing through flame
Solution Approach 1:
The patent changes the material parameter of the descent rope from traditional natural fiber to fire-resistant synthetic material that maintains its structural integrity when exposed to fire. The rope is designed with specific physical parameters including increased length (greater than 80m), modified tensile strength, and fire resistance properties that prevent burning and breaking in hazardous environments.
3Speed
If fast descent is implemented to quickly leave the fire site, then the escape speed is improved, but the rescuee may be injured during landing due to lack of cushioning
Solution Approach 1:
The patent incorporates a cushioning layer within the coverall structure that is positioned to absorb impact forces during landing. This beforehand cushioning is integrated into the coverall design, providing protective padding that reduces the harmful effects of impact while allowing for controlled fast descent, thus resolving the contradiction between speed and injury prevention.
4Object-affected harmful factors
If complete life-saving devices with comprehensive protection are used, then the protection against fire hazards is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple protective functions into integrated components: the helmet combines oxygen supply with fire protection, the coverall integrates thermal insulation with cushioning, and the descent device combines braking with signaling. This merging approach reduces the number of separate components and simplifies the overall system while maintaining comprehensive protection against toxic gases and fire hazards.
