Fuel Tank Buffer Mounting via Interlocking Convex-Concave Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buffer member mounting structures between a fuel tank and a vehicle body face issues with adhesive degradation, poor cushioning, and high installation complexity, leading to unstable connections and increased worker burden.
Innovation Solution
A mounting structure featuring a buffer member with convex and concave portions that engage with a recess on the fuel tank, combined with a clip system, providing enhanced cushioning and preventing adhesive degradation, allowing for easy and stable installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive or double-faced tape is used to mount the buffer member, then the buffer member can be attached to the fuel tank, but the adhesive strength degrades over time due to plasticizer migration
Solution Approach 1:
The invention extracts the adhesive layer from the mounting structure, eliminating the plasticizer migration problem entirely. The buffer member is mounted directly to the fuel tank surface through mechanical engagement of protrusions with recesses, without any adhesive intermediary, thus preventing adhesive strength degradation over time
Solution Approach 2:
The invention introduces engagement protrusions and recesses as a mechanical intermediary connection mechanism between the buffer member and fuel tank. This mechanical engagement system replaces the chemical adhesive bond, providing a stable connection that does not suffer from plasticizer migration and adhesive aging
2Reliability
If adhesive is used to mount the buffer member, then the buffer member can be attached to the fuel tank, but high assembly accuracy is required and worker burden increases
Solution Approach 1:
The engagement protrusions on the buffer member are designed to automatically align with and engage into the recesses on the fuel tank surface during assembly. This self-aligning mechanism eliminates the need for precise manual positioning and high assembly accuracy, allowing workers to simply press the buffer member onto the fuel tank for secure mounting
Solution Approach 2:
The mounting interface is segmented into discrete engagement protrusions and corresponding recesses, creating distinct alignment features that guide the buffer member into proper position during assembly. This segmentation provides natural alignment points that simplify the assembly process and reduce worker burden
3Device complexity
If a tabular buffer member is used, then the structure is simple, but the cushion feature is poor
Solution Approach 1:
The buffer member incorporates engagement protrusions at specific locations on its surface, creating localized structural features that enhance both mounting capability and cushioning performance. These protrusions concentrate force distribution at key points, improving cushion effectiveness without requiring a completely complex overall structure
