Linearly Adjustable Clip Assembly for Vehicle Fit Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clip assemblies often fail to allow for linear adjustment between components, which is necessary for accommodating various vehicle styles and geometries during manufacturing, particularly in securing components like doors and tail lights to a vehicle frame.
Innovation Solution
A clip assembly is designed with a rail member that is linearly adjustable relative to an attachment member, featuring a rail beam with end walls, a ledge, and support ribs, and an attachment member with coupling brackets and ledge-engaging arms, enabling secure and adjustable connection between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed clip assembly is used to connect components, then the connection is stable and secure, but the components cannot be adjusted linearly relative to each other
Solution Approach 1:
The clip assembly transitions from a fixed structure to a dynamic adjustable structure. The rail member can slide linearly within the coupling brackets, allowing continuous adjustment of the distance between components while maintaining a secure connection. This dynamic capability enables adaptation to different vehicle styles and geometries without requiring multiple fixed clip designs.
Solution Approach 2:
The clip assembly is divided into separable components: a rail member and coupling brackets. The rail member can be independently adjusted within the coupling brackets, allowing linear adjustment while maintaining overall structural integrity. This segmentation enables the adjustment function without requiring complete redesign of the entire connection system.
2Adaptability or versatility
If customized fastening assemblies are designed for each vehicle style, then the connection is optimized for specific geometries, but the manufacturing process becomes complex and time-consuming
Solution Approach 1:
The clip assembly is designed as a universal fastening system that can accommodate multiple vehicle styles and geometries through linear adjustment. A single clip assembly design can be used across different vehicle models by adjusting the rail member position, eliminating the need for multiple customized fastening assemblies and significantly improving manufacturing productivity.
Solution Approach 2:
The distance between components can be adjusted by changing the position parameter of the rail member within the coupling brackets. This parameter adjustment allows the same clip assembly to fit different vehicle geometries without modifying the fundamental design, enabling rapid adaptation to various vehicle styles while maintaining consistent manufacturing processes.
3Manufacturing precision
If components are secured with a non-adjustable clip, then the connection is strong and stable, but linear variation tolerance is limited
Solution Approach 1:
The clip assembly incorporates a dynamic sliding mechanism that allows the rail member to move linearly within the coupling brackets. This dynamic feature provides high linear variation tolerance by accommodating positional adjustments during assembly while maintaining a strong and stable connection once positioned.
Solution Approach 2:
The rail member acts as an intermediary element between the coupling brackets and the components being joined. It provides a sliding interface that absorbs linear variations and misalignments, making the assembly process easier by accommodating tolerance ranges without requiring precise pre-positioning of components.
