Coiled Gasket Clip Fastener for Damage-Free Woven Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clip fasteners for attaching tubular gaskets to oven doors are prone to pricking operators' hands and damaging fiberglass, and either require labor-intensive embedding or are difficult to extract without damaging the gasket, leading to inefficiencies and sealing issues.
Innovation Solution
A clip fastener with a resilient metal wire design featuring a mounting surface engagement head, neck, and a coiled base with protrusions that allows easy rotation and embedding into woven gaskets, along with an equipment for automatic and rapid mounting using a rotatable nose and motor-driven mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional clip fastener with up-wrapped tail is used, then the gasket can be attached to the mounting surface, but the tail pricks operators' hands and damages fiberglass during manual embedding
Solution Approach 1:
The harmful up-wrapped tail is completely removed from the clip fastener design. The base is reformulated as a coiled structure with ends that lie flat against the mounting surface, eliminating the protruding tail that causes pricking during manual embedding operations.
Solution Approach 2:
Instead of having the tail wrap upward as in traditional designs, the base coils downward with ends that lie flat against the surface. This inversion of the wrapping direction eliminates the harmful protruding tail while maintaining the anchoring function.
2Stability of the object's composition
If a multi-coil base is used to improve embedding stability, then the clip can be firmly attached, but the multi-coil structure causes silk-spinning of fiberglass and affects sealing
Solution Approach 1:
The base uses a uniform single-coil structure with consistent radius throughout, rather than variable or multi-coil designs. This uniform local quality prevents the silk-spinning effect on fiberglass while maintaining adequate embedding stability through the coiled configuration.
3Ease of operation
If a loom-type weaving clip fastener is used to avoid labor-intensive rotation, then embedding becomes automated, but the clip cannot be extracted without forced extraction that destroys the woven structure
Solution Approach 1:
The coiled base structure provides dynamic flexibility that allows the clip to be easily inserted and rotated into the woven gasket during installation, while also enabling easy extraction by simply pulling the head, without forcing or damaging the woven fiberglass structure.
4Ease of manufacture
If manual operation and simple changes to existing equipment are used for mounting clip fasteners, then the process can be performed with existing tools, but the mounting efficiency remains low
Solution Approach 1:
The coiled base structure with protrusions is designed to be self-aligning and self-embedding during the mounting process. The protrusions guide the base into the woven gasket automatically during rotation, reducing the need for complex positioning mechanisms and enabling faster manual or automated installation.
