Handlebar Airbag Bulge Posture Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airbag apparatus configurations struggle to stabilize the posture of airbags deployed in handlebars of saddle riding vehicles, as the technology adapted from body frame applications is not effectively applicable for posture control in this context.
Innovation Solution
A saddle riding vehicle design featuring a steering system with a handlebar, a meter positioned lower than the handlebar, and an airbag apparatus including an inflator, airbag, and retainer, where the airbag deploys with a bulge portion that bulges toward the meter to stabilize its posture during deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an airbag apparatus is disposed in the handlebar, then the airbag can be positioned closer to the occupant for better protection, but it becomes difficult to control the posture of the airbag during deployment
Solution Approach 1:
The airbag is designed with a specific local quality feature: a bulge portion that protrudes downward. This localized structural characteristic ensures that the airbag deploys in a controlled posture with the bulge portion facing the occupant, providing effective protection while maintaining stability during deployment in the handlebar position.
2Speed
If the airbag deploys without a specific posture control mechanism, then the deployment speed is fast, but the airbag posture becomes unstable during deployment
Solution Approach 1:
The airbag incorporates a bulge portion as a local structural feature that naturally guides the deployment posture. This design allows the airbag to maintain stability during rapid deployment without requiring additional complex control mechanisms, as the bulge portion inherently directs the airbag to face the occupant correctly.
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
This configuration allows for the easy stabilization of the airbag's posture during deployment, effectively reducing the impact on the occupant by ensuring the airbag is deployed in a suitable position and maintaining stability.
Implementation Method 1
an airbag that deploys with gas emitted by the inflator
