Retractable Enclosure Zipper Support Structure for Wrinkle-Free Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retractable enclosure zippers face manufacturing complexity and are prone to wrinkling due to lack of support, affecting their appearance and aesthetics.
Innovation Solution
A retractable enclosure zipper with a support structure comprising a supporting cloth and a support member, arranged on the inner side of the zipper cloth, which supports the zipper teeth and retractable cloth, ensuring a flat and wrinkle-free appearance, and can be made of lightweight materials like plastic, metal, wood, leather, or foam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a wire bracket structure is used to support the zipper, then the zipper maintains a flat appearance without wrinkles, but the manufacturing process becomes complicated and weight increases
Solution Approach 1:
The invention extracts and eliminates the complex wire bracket structure from the design. Instead of using a separate supporting frame, the patent integrates the support function directly into the zipper assembly by using the interlocking zipper teeth themselves as the support mechanism, thereby simplifying the manufacturing process while maintaining the flat appearance
Solution Approach 2:
The invention merges the support function with the zipper structure itself. The zipper teeth and interlocking mechanism are designed to provide structural support, eliminating the need for separate support components. This integration maintains the flat appearance without adding manufacturing complexity
2Shape
If a wire bracket structure is used to support the zipper, then the zipper maintains a flat appearance without wrinkles, but the weight of the zipper increases
Solution Approach 1:
The invention removes the heavy wire bracket structure and replaces it with a lightweight zipper design where the teeth and interlocking mechanism provide the necessary support. This extraction of the heavy supporting frame significantly reduces the overall weight while maintaining the flat appearance through the zipper's own structural integrity
3Ease of manufacture
If the zipper cloth is directly sewn to the retractable enclosure without support, then the manufacturing process is simple and weight is reduced, but the zipper becomes prone to wrinkles and loses aesthetic appeal
Solution Approach 1:
The invention applies the self-service principle by designing the zipper teeth and interlocking mechanism to automatically provide structural support without requiring external support components. The zipper structure serves its own support function, maintaining a wrinkle-free appearance while keeping the manufacturing process simple and direct sewing
