Cap Structure Breach Holes for Zipper Head Elastic Piece Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional zipper head assembly structures face challenges in efficiently retaining an elastic piece, which affects production efficiency and robustness, due to the lack of effective breach hole features in the cap structure.
Innovation Solution
The cap structure incorporates multiple breach hole features, including first retaining blocks and through holes, which are formed using a die casting process and punching machine, allowing for enhanced retention of an elastic piece within the cap body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cap structure without breach hole features is used, then the structure is simple, but the retention of elastic piece is insufficient
Solution Approach 1:
The cap structure is segmented by introducing multiple breach holes (first through holes and second through holes) that divide the cap body into distinct regions. These breach holes are strategically positioned to allow the elastic piece to pass through and be retained by retaining blocks, thereby improving retention reliability while maintaining a relatively simple overall structure.
Solution Approach 2:
The cap structure incorporates local quality variations by adding retaining blocks at specific locations within the breach holes. These retaining blocks are positioned to contact and retain the elastic piece locally, providing enhanced retention only where needed rather than requiring a complete structural redesign of the entire cap.
2Productivity
If conventional assembly procedure is used, then the assembly process is straightforward, but production efficiency is low
Solution Approach 1:
The cap structure is designed with pre-formed breach holes and retaining blocks that are integrated into the cap body during manufacturing. This preliminary preparation allows the elastic piece to be quickly installed by simply passing it through the pre-configured breach holes and engaging it with the retaining blocks, significantly improving assembly speed and production efficiency without requiring complex additional assembly steps.

AI summary
A cap structure includes a cap body and an elastic piece. The cap body has at least two first inner concave grooves corresponding to each other, at least two first retaining blocks corresponding to each other and respectively extended outwardly from the at least two first inner concave grooves, and at least two first through holes corresponding to each other and respectively adjacent to the at least two first retaining blocks. The at least two first inner concave grooves are disposed on the inner surface of the cap body, and the at least two first through holes pass through the cap body to form two breach holes between the inner and the outer surfaces of the cap body. The elastic piece is disposed on the inner surface of the cap body, and the at least two first retaining blocks contact the elastic piece for retaining the elastic piece.
