Dynamic Airbag Pressure Control for High-Fall Stunt Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety systems for high fall stunts primarily rely on determining the density of landing pads based solely on the performer's weight, which is done non-real-time and does not account for other factors like platform height, falling velocity, and wind speed, limiting the optimization of impact energy absorption.
Innovation Solution
An airbag system with a control system that adjusts air pressure in real-time using sensors to measure weight, distance, and environmental conditions to optimize energy absorption during the stunt, employing a scale, laser range finder, optical sensor, lidar sensor, radar sensor, and anemometer to determine and adjust air pressure based on performer weight, distance, and wind conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the landing pad density is set based solely on performer weight in advance, then the setup process is simple, but the safety optimization is insufficient due to not accounting for real-time factors like height, velocity, and wind conditions
Solution Approach 1:
The airbag system transitions from a static density configuration to a dynamic one where air pressure is continuously adjusted based on real-time measurements of performer weight, platform height, and environmental conditions. The control system modifies the airbag's physical state (pressure/density) dynamically to optimize safety for each specific stunt configuration.
Solution Approach 2:
The system implements feedback loops where sensors continuously measure performer weight, platform height, and wind conditions, and this information is fed back to the control system which adjusts the airbag pressure accordingly. This closed-loop control ensures the landing pad density is optimized based on actual stunt parameters rather than pre-set values.
2Use of energy by moving object
If the air pressure is adjusted in real-time based on multiple parameters, then the energy absorption is optimized, but the system complexity and measurement requirements increase
Solution Approach 1:
The control system serves multiple functions: it measures performer weight via scale data, calculates platform height using sensor inputs, monitors environmental conditions, and adjusts airbag pressure accordingly. By consolidating these diverse measurement and control functions into a single multi-functional system, the patent reduces overall system complexity despite the increased measurement requirements.
Solution Approach 2:
The system replaces manual density adjustment mechanisms with automated electronic control. Instead of physically adding or removing padding material based on performer weight, the system uses electronic sensors and a control algorithm to automatically adjust air pressure, eliminating the need for manual mechanical adjustment and reducing operational complexity.
3Adaptability or versatility
If the landing pad uses fixed density configuration, then the device complexity is low, but the adaptability to different stunt conditions is limited
Solution Approach 1:
The airbag system transitions from a static density configuration to a dynamic one where air pressure is continuously adjusted based on real-time measurements of performer weight, platform height, and environmental conditions. The control system modifies the airbag's physical state (pressure/density) dynamically to optimize safety for each specific stunt configuration.
Solution Approach 2:
The system changes the physical parameter of air pressure within the airbag to adapt to different stunt conditions. By varying the air pressure parameter based on measured conditions (weight, height, wind speed), the landing pad's density and energy absorption characteristics are adjusted to match the specific requirements of each stunt scenario.

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.
