Airbag Pressure Control for High-Fall Impact Energy Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airbag safety systems for high fall stunts primarily rely on pre-performance adjustments based on performer weight, failing to account for real-time environmental and dynamic factors like platform height, falling velocity, and wind speed, which limits the optimization of impact energy absorption.
Innovation Solution
An airbag system with a control system that determines performer weight, measures distance and wind conditions, calculates theoretical and actual velocities, and adjusts air pressure in real-time to optimize energy absorption during the stunt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-performance air pressure adjustment is made based on performer weight only, then the system is simple to operate, but it fails to account for real-time environmental and dynamic factors like platform height, falling velocity, and wind speed
Solution Approach 1:
The airbag system transitions from static pre-performance adjustment to dynamic real-time adjustment. The control system continuously monitors platform height, falling velocity, and wind speed during the stunt, and adjusts air pressure accordingly. This dynamic adaptation allows the system to respond to changing conditions and optimize safety for each specific performance scenario.
Solution Approach 2:
The system incorporates real-time feedback mechanisms where sensors monitor actual falling parameters (velocity, distance, wind conditions) and feed this information back to the control system. The control system uses this feedback to calculate required air pressure adjustments and modulates the airbag accordingly, creating a closed-loop control system that adapts to actual performance conditions.
2Reliability
If air pressure is adjusted in real-time based on multiple factors, then impact energy absorption is optimized, but the device complexity increases
Solution Approach 1:
The control system is designed to handle multiple functions: monitoring platform height, measuring falling velocity, detecting wind speed, calculating impact energy, and adjusting air pressure. By consolidating these functions into a single integrated control system, the patent reduces overall system complexity while maintaining comprehensive safety optimization capabilities.
Solution Approach 2:
The system replaces manual mechanical adjustment methods with automated electronic control. Instead of physically adjusting air pressure based on pre-calculated values, the system uses electronic sensors and processors to continuously monitor conditions and automatically modulate airbag pressure, simplifying the operational complexity while improving reliability.
3Adaptability or versatility
If pre-performance density setting is used, then the setup process is simple, but it cannot account for changing conditions during the stunt
Solution Approach 1:
The system performs preliminary calculations of impact energy and required air pressure based on planned performance parameters before the stunt begins. This preliminary setup establishes baseline values and configuration settings, allowing the system to be ready for real-time adjustments without requiring extensive setup time during actual performance.
Solution Approach 2:
The airbag system performs self-adjustment during the stunt based on real-time sensor data. The control system automatically monitors falling velocity, platform height, and wind conditions, and autonomously modulates air pressure without requiring external intervention or manual adjustment, enabling real-time adaptation while minimizing setup time requirements.

AI summary
Aspects of the disclosure relate to methods, apparatus, and systems for optimizing an energy exerted on a performer falling from an elevated platform and impacting an airbag. A system is configured to determine a weight of the performer to fall from the elevated platform toward the airbag, measure a distance between the elevated platform and the airbag, and set an air pressure of the airbag based on the weight and the distance prior to the performer falling toward the airbag. The system is further configured to determine, while the performer falls toward the airbag, a velocity the performer will reach upon impact with the airbag, and adjust the air pressure of the airbag based on the velocity while the performer falls toward the airbag to optimize an energy exerted on the performer when the performer impacts the airbag.
