Building-Integrated Rescue Boom for High-Rise Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Evacuating people from high or great heights, such as wind turbines and high-rise buildings, poses challenges due to the limitations of traditional rescue methods like helicopters in fire situations, where they are either too slow or too risky.
Innovation Solution
A personal rescue system featuring a structure-mounted bracket with a self-extending boom and a rescue basket that can be extended horizontally, allowing for autonomous operation without external power, providing a safe and reliable means to transport individuals away from danger zones, and can be reused with minimal costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If helicopter rescue is used to evacuate people from high structures, then rescue coverage is improved, but response time increases and safety deteriorates in fire situations
Solution Approach 1:
The rescue system is pre-installed on the structure with the boom in a retracted position. All components are prepared in advance including the self-extending mechanism, rescue cage, and structural mounting, so that evacuation can begin immediately without waiting for external rescue resources to arrive.
Solution Approach 2:
The boom is designed to be self-extending using stored potential energy from a pre-tensioned spring or pre-positioned weight, eliminating the need for external power supply or manual operation during the emergency evacuation process.
2Adaptability or versatility
If helicopter rescue is used to evacuate people from high structures, then rescue coverage is improved, but safety deteriorates due to operating near fire
Solution Approach 1:
The self-extending boom acts as an intermediary mechanical system that transports persons directly from the structure to a safe position without requiring helicopter proximity to the fire zone. The rescue cage serves as a protected intermediary environment during transport.
3Ease of operation
If a traditional rescue system with external power supply is used, then functionality is improved, but reliability deteriorates when power supply is compromised
Solution Approach 1:
The boom utilizes a self-extending mechanism with a pre-tensioned spring or pre-positioned weight that stores potential energy, eliminating dependence on external power supplies. The system automatically extends when activated, ensuring operation remains reliable even when electrical power is compromised.
4Speed
If vertical evacuation is used to move people away from danger, then evacuation speed is improved, but safety deteriorates due to falling debris
Solution Approach 1:
The system transitions from purely vertical evacuation to horizontal evacuation by extending the boom outward from the structure. This dimensional change moves persons laterally away from the building envelope where falling debris is most likely to occur, while maintaining rapid evacuation capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively moves people to a safe horizontal distance from the danger area, reducing risks from falling debris and allowing for helicopter rescue, enabling simultaneous rescues from multiple heights and ensuring safety in various environments, including water surfaces.
Implementation Method 1
the boom includes, for example, a spring or a similar pre-tensioning device that is pre-tensioned when the boom is retracted
Implementation Method 2
It is also intended that the required energy be stored as potential energy, for example, using a weight
