Airbag Lid Cover Segmentation for Exterior Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airbag devices for vehicles face challenges in maintaining exterior design integrity and applicability across different models, as the module cover must be designed differently to accommodate various vehicle body exteriors, limiting their universal application and aesthetic integration.
Innovation Solution
The airbag device incorporates a lid cover that is designed to be released during deployment, allowing it to be formed from the same material as other exterior parts, ensuring seamless integration and flexibility in design, without hindering the opening movement of the lid, and can be adjusted to open without fail, enhancing the airbag's deployment and the motorcycle's external appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the module cover is designed to make up the vehicle body exterior, then the exterior design integrity is improved, but the applicability across different motorcycle models deteriorates due to the need for different designs for different models
Solution Approach 1:
The cover is divided into two separate parts: the lid (62) which is functionally related to airbag deployment and the lid cover (70) which serves as the exterior panel. This segmentation allows the lid cover to be designed purely for exterior aesthetics while the lid handles the deployment function, enabling the lid cover to be universally applied across different motorcycle models without compromising exterior design integrity.
Solution Approach 2:
The exterior design function is extracted from the functional deployment structure. The lid cover (70) is separated as an independent exterior panel that can be designed to match various motorcycle body styles, while the lid (62) retains the deployment functionality. This extraction allows the same lid cover design to be used across different models.
2Ease of operation
If the module cover is designed to open during deployment, then the airbag deployment function is improved, but the exterior design integrity deteriorates due to the difficulty of securing integration with other exterior parts
Solution Approach 1:
The cover structure is segmented into the lid (62) with tear line (68) for deployment opening and the lid cover (70) as a separate exterior panel. The lid cover is fixed to the vehicle body while the lid can open during deployment. This segmentation allows the exterior panel to maintain design integrity while the functional lid provides opening movement capability.
3Ease of operation
If the lid cover is made from the same material as other exterior parts, then the material integration is improved, but the manufacturing complexity increases due to the need to ensure both exterior quality and deployment functionality
Solution Approach 1:
The cover system is divided into the lid (62) made of functional material suitable for deployment with tear line, and the lid cover (70) made of exterior-grade material matching other vehicle panels. This segmentation allows each component to be manufactured with appropriate material properties without compromising the other, reducing overall manufacturing complexity while achieving both exterior quality and deployment functionality.
