Multi-Tape Zipper Assembly with Segmented Sliders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional zipper assemblies require multiple zipper tapes for multiple openings, leading to cumbersome production and prone zipper pullers and sliders to detach from the tape ends after closing.
Innovation Solution
A zipper assembly utilizing at least three zipper tapes, where each tape is divided into halves with zipper teeth on both sides, allowing for a 'Y', 'T', or three-dimensional structure, with pullers and sliders slidably installed to maintain stability and prevent detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple zipper tapes are used for multiple openings, then multiple openings can be opened and closed, but production becomes cumbersome due to repeated sewing
Solution Approach 1:
The patent combines multiple zipper tapes into a single integrated zipper assembly where multiple zipper tapes share common ends that are fixed to the same fastening component. This merging approach allows multiple openings to be controlled by a single zipper puller system, significantly reducing the number of separate sewing operations required during production while maintaining the functionality of multiple independent openings.
2Reliability
If zipper puller and slider are located at the zipper tape end after closing, then the zipper is fully closed, but they are prone to coming off from the zipper tape end
Solution Approach 1:
The patent segments the zipper tape into multiple sections with distinct functional zones. The zipper puller and slider are positioned at specific locations along the zipper tape rather than always at the end, creating intermediate stopping positions that prevent the components from sliding off the tape end while still achieving complete closure of all openings.
3Ease of manufacture
If a single opening is designed in the product, then production is simplified, but the requirements of taking and putting items inside cannot be met
Solution Approach 1:
The patent designs a multi-functional zipper assembly where a single integrated zipper structure with multiple tapes provides multiple independent openings. This allows the zipper system to serve multiple purposes - enabling selective access to different compartments or openings while maintaining a unified, simplified production process. The single zipper assembly replaces what would traditionally require multiple separate zipper installations.

AI summary
The present invention relates to the field of zippers, and discloses a zipper assembly, including at least three zipper tapes. Zipper teeth are provided on the sides of the zipper tapes. Each zipper tape includes a first half of the zipper tape and a second half of the zipper tape. Among the at least three zipper tapes, the first half of one zipper tape and the second half of the one zipper tape are respectively arranged corresponding to the second half of another zipper tape adjacent to the one zipper tape and the first half of the rest one zipper tape adjacent to the one zipper tape. Zipper puller and slider are slidably installed on the opposite sides of the zipper teeth on the first half and the second half of each zipper tape. One zipper tape is divided into two halves, and the zipper teeth of two adjacent halves of the zipper tapes are meshed. The zipper pullers and sliders are located in the middle of the zipper tapes when reaching the end points where the zippers are closed. The zipper pullers and sliders do not easily detach from the zipper tapes, ensuring the practicality of the zipper assembly.
