Airbag Stabilizing Mechanism for Two-Wheeled Vehicle Ejection Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety airbag designs for two-wheeled vehicles inadequately protect riders from impacts coming from various directions and fail to prevent ejection, as they are primarily designed for front-end impacts and lack comprehensive coverage.
Innovation Solution
An airbag safety system with multiple modules, including front, rear, and side airbags, equipped with a stabilizing mechanism using fastening elements like VELCRO fasteners to maintain airbag orientation and a head capping structure for enhanced protection, ensuring the airbags form a stable, ergonomic space around the rider to prevent ejection and absorb impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple airbags are deployed to provide comprehensive protection from all directions, then protection coverage is improved, but device complexity increases
Solution Approach 1:
The protection system is divided into multiple independent airbag modules (front airbag, rear airbag, two side airbags) that can be selectively deployed based on impact direction. Each airbag module includes its own inflation module and sensing devices, allowing independent operation while collectively providing comprehensive 360-degree protection coverage.
Solution Approach 2:
The airbags are stored in a nested or folded configuration within the vehicle structure before deployment. The multiple airbag modules are arranged to fit within limited space, with each airbag containing or adjacent to its inflation module, creating a compact integrated assembly that expands into full protection coverage when activated.
2Speed
If airbags are inflated to rapidly protect the rider, then response speed is improved, but energy consumption increases
Solution Approach 1:
The airbags and inflation modules are pre-positioned and pre-charged within the vehicle structure before an accident occurs. The sensing devices continuously monitor for impact conditions, and upon detection, the pre-positioned inflation modules immediately activate to inflate the airbags, eliminating deployment lag while using stored energy rather than requiring continuous power input.
3Stability of the object's composition
If a stabilizing mechanism is added to maintain airbag orientation, then protection stability is improved, but device complexity increases
Solution Approach 1:
The airbags incorporate self-stabilizing features through their geometric design and inflation characteristics. The airbags naturally orient themselves in stable configurations upon inflation due to their shape and the forces involved, eliminating the need for complex active stabilization mechanisms while maintaining consistent protective orientation.
4Reliability
If head capping structure is added to prevent ejection, then rider safety is improved, but device complexity increases
Solution Approach 1:
The head capping function is integrated into the existing front airbag structure rather than being a separate component. The front airbag is designed with an extended or shaped configuration that naturally forms a cap over the rider's head when inflated, combining head protection and body protection into a single integrated airbag module, thereby preventing ejection without adding separate structural complexity.
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 cushions impacts from any direction, prevents rider ejection, and minimizes injuries by maintaining airbag orientation and providing comprehensive head and neck protection through the stabilizing mechanism and head capping structure.
Implementation Method 1
Each airbag module includes a gas generator configured to generate gas to inflate the airbag

AI summary
An airbag safety system is provided with two or more safety airbags which can be adjoined to protect the rider when a crash occurs. A stabilizing mechanism is used to cause the inflated airbags to adjoin each other so as to form a stable protection space between the vehicle and the adjoined airbags. The adjoined airbags are shaped to meet a rider's ergonomics, making sure the rider can be caped for head protection and can be protected within the space surrounded by the airbags from being thrown away off the vehicle and subject to serious injuries.
