Vehicle Interior Lens Mounting for Easier Light Guide Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of vehicle door lining components, specifically the lens between the door lining main body and the switch panel, is complex due to the need for precise positioning, making it difficult to connect the light guide member to the interior member main body.
Innovation Solution
A vehicle interior member design featuring a resiliently deformable lens with engaging portions that can be easily connected to the interior member main body, allowing for easy alignment and secure mounting of the light guide member, which includes a groove and projecting walls for engagement with the interior member main body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lens is clamped between the door lining main body and the switch panel with precise positioning, then the light guide member can be securely connected, but the assembly work becomes complex and time-consuming
Solution Approach 1:
The lens is divided into multiple functional segments: a groove for receiving the light guide member, first and second engaging portions for connection, and a resiliently deformable body. This segmentation allows each part to perform its specific function independently, simplifying the overall assembly process while maintaining secure connection.
Solution Approach 2:
The lens body is designed to be resiliently deformable, allowing it to dynamically adjust during assembly. The deformability enables the engaging portions to flexibly engage with the door lining main body without requiring precise positioning, reducing assembly complexity while ensuring reliable connection.
2Manufacturing precision
If the lens is made rigid for stable positioning, then the positioning accuracy improves, but the ease of connection to the interior member main body decreases
Solution Approach 1:
The lens body is designed with resilient deformability, allowing it to flex during the connection process and then maintain a stable position once engaged. This dynamic property enables easy connection without compromising positioning precision after assembly.
Solution Approach 2:
The lens material properties are selected to provide controlled deformability within a specific range. This allows the lens to be flexible enough for easy assembly but rigid enough to maintain precise positioning once connected, effectively changing the physical state parameter of rigidity/flexibility as needed.
