Vehicle Interior Cover Structure for Touch UI and Airbag Break-Apart
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle interior components lack an effective and aesthetically pleasing user interface system that integrates input and output devices seamlessly, while also considering the deployment of airbags.
Innovation Solution
A composite structure for a vehicle interior component featuring a cover base and a cover layer, where the cover layer is molded on the cover base and includes a projection to fit within a recess, facilitating the presentation of a user interface with an input device and an output device, such as a light display. The component is designed to break apart to facilitate airbag deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a composite structure with cover layer and cover base is used to create an integrated user interface, then the aesthetic appearance and functional integration are improved, but the structural complexity increases
Solution Approach 1:
The patent merges the cover layer and cover base into a single composite structure that provides both aesthetic coverage and structural support. The cover layer is molded onto the cover base to form an integrated user interface component, combining multiple functions (protection, aesthetics, input device housing) into one unified structure.
Solution Approach 2:
The composite cover structure serves multiple functions simultaneously: the cover layer provides aesthetic coverage and houses input devices, while the cover base provides structural support and mounting functionality. This multi-functional design reduces the need for separate components.
2Ease of manufacture
If the component is designed as a single integrated structure, then the manufacturing process is simplified, but the ability to facilitate airbag deployment is reduced
Solution Approach 1:
The patent segments the cover structure into a cover layer and cover base that can separate upon airbag deployment. The cover layer is molded onto the cover base but designed with separation capability, allowing the structure to remain integrated during manufacturing while enabling segmentation during emergency deployment.
Solution Approach 2:
The cover structure transitions from a static integrated form during manufacturing and normal operation to a dynamic separable form during airbag deployment. The structure adapts its configuration based on operational conditions, remaining unified during assembly but capable of separation when safety requirements demand.
3Ease of operation
If the cover layer is made softer than the cover base, then the user interface touch sensitivity is improved, but the structural strength is reduced
Solution Approach 1:
The patent applies different material hardnesses to different parts of the cover structure. The cover layer uses a softer material for enhanced touch sensitivity and user interaction, while the cover base uses a harder material for structural strength and support. Each layer's material property is optimized for its specific function.

AI summary
A component for a vehicle interior may comprise a composite structure comprising a cover structure comprising a cover base, a cover layer and a cover surface. The cover structure may provide a user interface comprising an input device. The cover layer may cover at least a portion of the cover base. The cover base may comprise a core and a perimeter. The cover layer may deform between the core and the perimeter. The core may provide the cover surface for the input device. The cover layer may be softer than the cover base. The cover layer may be molded on the cover base. The cover layer may comprise a projection fit within a recess in the cover base. The cover surface may comprise a surface of the core projecting above a surface of the cover layer. The cover structure may comprise a decorative layer on the cover layer.
