Motorcycle Airbag Garment Sensor Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycle riders are more susceptible to accidents and injuries due to the lack of onboard safety devices, as existing protective systems for motorcycle riders are not integrated into the vehicle and often require manual activation, which may not deploy promptly or effectively in high-speed collisions.
Innovation Solution
An airbag-equipped garment system with an electronic deployment system that includes sensors to detect motorcycle speed, separation, tilt, and collision, ensuring rapid and automatic inflation of airbags when predetermined conditions are met, providing comprehensive upper body protection without obstructing the rider's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing protective systems are used for motorcycle riders, then some level of protection is provided, but the systems require manual activation and are not integrated into the vehicle, resulting in delayed or ineffective deployment in high-speed collisions
Solution Approach 1:
The system automatically detects collision conditions through sensors and triggers airbag deployment without requiring manual intervention from the rider. The electronic control unit monitors sensor inputs and autonomously activates the deployment mechanism, making the system self-activating and eliminating the need for manual operation during critical moments
Solution Approach 2:
The protective system is integrated directly into the motorcycle garment and vehicle, combining the airbag mechanism, sensors, and control systems into a unified automated deployment system that works in conjunction with the motorcycle's existing safety infrastructure
2Reliability
If airbag-equipped garment system with multiple sensors is implemented, then comprehensive protection and rapid automatic deployment are achieved, but the device complexity and cost increase
Solution Approach 1:
The protective system is divided into separate functional modules: collision sensors, speed sensors, tilt sensors, an electronic control unit, and airbag deployment mechanisms. Each component performs a specific function and can be independently optimized, maintained, or replaced, reducing overall system complexity while maintaining comprehensive protection capabilities
Solution Approach 2:
The electronic control unit serves multiple functions by processing inputs from various sensors (collision, speed, tilt) and coordinating the deployment of airbags based on different accident scenarios. This multi-functional approach consolidates control logic into a single unit, reducing the need for multiple separate control systems
3Ease of operation
If the garment is designed to be relatively unobtrusive prior to inflation, then rider acceptance increases, but the protective enclosure volume is reduced when needed
Solution Approach 1:
The garment transitions from a compact, low-profile state during normal riding to an expanded protective enclosure state during deployment. The airbag mechanism inflates the garment rapidly, creating a rigid protective structure that adapts to the rider's body shape while providing comprehensive protection against impact forces

Function Achieved in This Case
The system effectively minimizes impact injuries by providing rapid and automatic airbag deployment in accident scenarios, enhancing rider safety without compromising the motorcycle's design or requiring manual intervention, thus reducing the risk of severe bodily harm.
Implementation Method 1
a sensor for sensing the speed of the motorcycle and activating the inflatable means only when the speed of the motorcycle exceeds a predetermined amount
Implementation Method 2
first sensing means for sensing the separation of the motorcycle rider from the motorcycle and for rapidly deploying gas from the source of gas into the inflatable member
Implementation Method 3
second sensing means for sensing the tilt of a motorcycle from vertical and for rapidly deploying gas from the source of gas into the inflatable member when the tilt of the motorcycle exceeds a preselected angle
Implementation Method 4
means independent of the activating means for sensing a collision involving the motorcycle and for rapidly deploying gas into the member in response to the collision
Implementation Method 5
means for rapidly deploying said gas into said inflatable member
Implementation Method 6

AI summary
An airbag equipped garment and deployment system for a motorcycle rider includes an inflatable garment shaped member for encompassing an upper body of a motorcycle rider and a mass of compressed gas. The system includes a first sensor for detecting the separation of the rider from the motorcycle and a second sensor for detecting the tilt of the cycle and deploying the gas when the rider separates from the motorcycle or the tilt exceeds a pre-selected value. A separate sensor senses a collision for deployment of gas in the event of a collision while a separate sensor deactivates the system until the speed of the motorcycle has reached a predetermined speed.
