Integrated Sealing Fastener for Vehicle Component Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fasteners for connecting vehicle components often require secondary forming processes for sealing, which complicates manufacturing and may not provide a reliable seal between components.
Innovation Solution
A fastener with an integrally formed sealing portion that includes a side wall and extension portion, allowing for a sealing connection without additional processing, and features a connection portion with inclined surfaces and retention arms for secure clamping and rotation, facilitating easy assembly and sealing between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing fasteners use separate sealing components or secondary forming processes, then sealing function can be achieved, but manufacturing complexity increases and manufacturing time is extended
Solution Approach 1:
The patent combines the sealing function directly into the fastener body by integrating a sealing ring into the connection portion. This merging of functions eliminates the need for separate sealing components and secondary forming processes, thereby reducing manufacturing complexity while maintaining reliable sealing between vehicle components.
Solution Approach 2:
The sealing ring is pre-integrated into the fastener connection portion during manufacturing. This preliminary action ensures that the sealing function is already prepared and built-in before assembly, eliminating the need for additional sealing steps during the assembly process and reducing overall manufacturing time.
