Sliding Fastener Stripe Pattern Weaving Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide fasteners do not enhance the aesthetic appearance of tape side edge portions at the outer side of end stops in the tape longitudinal direction.
Innovation Solution
A slide fastener with woven fastener tapes featuring stripe patterns along the longitudinal direction of the tape side edge portions at the outer side of end stops, created using thicker core strings and weft threads, which are woven to form a decorative texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multi-color strings are woven or knitted into the tape side edge portion to form a colorful decoration portion, then the aesthetic appearance of the fastener is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by varying the color parameters of weft threads along the longitudinal direction of the fastener tape to create stripe patterns. Instead of using multi-color core strings woven into the tape edge, the invention changes the color parameters of regularly arranged weft threads, thereby achieving aesthetic decoration through parameter variation rather than structural complexity.
Solution Approach 2:
The patent applies local quality by creating stripe patterns in specific regions of the tape side edge portions, particularly at outer sides of end stops. The weft threads are arranged to form decorative stripe patterns in these specific local areas, while other portions of the tape maintain their functional structure without unnecessary decorative complexity.
2Ease of manufacture
If stripe patterns are formed by weaving texture of weft threads and core strings, then the manufacturing cost is reduced, but the aesthetic appearance may be compromised
Solution Approach 1:
The patent resolves this contradiction by using parameter changes in the weaving process. Different color weft threads are woven in a regular pattern to create stripe patterns, which can be achieved through standard weaving process parameters without requiring additional coloring steps or complex multi-color materials, thus maintaining both aesthetic appearance and manufacturing ease.

AI summary
Provided is a sliding fastener that can increase the aesthetics of the portion that is outside in the tape length direction from stops that are at the tape side edges of a fastener tape. The present invention is provided with: a pair of fastener tapes (20) that formed by being woven; fastener element rows (30) having a plurality of fastener elements (31) and provided to each of the facing tape side edges (20a) of the pair of fastener tapes (20); a slider (40) that meshes/separates the pair of fastener element rows (30); and stops (11, 12) that are provided to the ends of the pair of the fastener element rows (30) and that stop the movement of the slider (40). A striped pattern (S) is formed along the lengthwise direction of the tape at the outer sections in the lengthwise direction of the fastener tapes (20) from the stops (11, 12) at the tape side edges (20a).
