Resin Cover Clip Squeezing Rib for Secure Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching a resin cover to a metallic frame using general-purpose metallic clips fail to securely fasten the cover when the hole dimensions in the frame are larger than the clips, leading to unreliable attachment due to easy clip dislodgment.
Innovation Solution
A resin cover with a clip squeezing portion featuring a flexure control rib is designed to restrict the deformation of the metallic clip's claw portion, ensuring secure attachment even when the clip does not conform to the original hole dimensions by setting the gap between the claw's extreme end and the flexure control rib smaller than the clip's protrusion, preventing easy pull-out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If general-purpose metallic clips are used to attach resin cover to metallic frame, then manufacturing cost and assembly time are reduced, but attachment reliability deteriorates when hole dimensions are larger than clip dimensions
Solution Approach 1:
The resin cover is designed with a localized clip squeezing portion that has a specific gap dimension. This local structural feature enables the clip to be reliably retained even when the hole dimension is larger than the clip dimension, resolving the contradiction between using general-purpose clips for productivity and maintaining attachment reliability.
Solution Approach 2:
The invention changes the parameter of the resin cover structure by introducing a clip squeezing portion with a controlled gap. This parameter change allows the system to accommodate dimensional variations between clips and holes while maintaining reliable attachment, thus preserving both productivity and reliability.
2Strength
If metallic clips are designed to fit smaller holes, then clip strength is improved, but adaptability to larger hole dimensions deteriorates
Solution Approach 1:
The clip squeezing portion of the resin cover acts as an intermediary structure between the metallic clip and the hole. It provides a localized retention mechanism that enables general-purpose clips (designed for smaller holes) to be reliably attached to larger holes, thus maintaining both clip strength and adaptability.
3Ease of operation
If hole dimensions in metallic frame are increased, then ease of assembly is improved, but clip retention reliability deteriorates
Solution Approach 1:
The resin cover is pre-formed with a clip squeezing portion that creates a retention mechanism before the clipping operation. This preliminary structural feature ensures that when the clip is inserted into a larger hole, it is automatically retained by the squeezing portion, thus maintaining both ease of assembly and clip retention reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables reliable fixation of the resin cover to metallic frames with larger hole dimensions using general-purpose clips, preventing easy dislodgment and ensuring stable attachment, thus addressing the issue of inconsistent hole dimensions and clip sizes.
Implementation Method 1
the flexure control rib restricts the deformation amount of a claw portion formed on the metallic clip to prevent the metallic clip from being pulled back from the hole portion formed in the structure
