Quick-Release Slide Fastener With Pulling Member And Positioners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick-release slide fasteners on textiles are inefficient for easy removal due to the need to directly pull the textile, which can be difficult and dirty, and the teeth may separate easily during normal use.
Innovation Solution
A pulling member is integrated beside the tooth easy-release region of the slide fastener, with quick positioners providing mutual positioning to stabilize and facilitate easy operation, preventing unnecessary separation of the teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the textile itself is used as the pulling portion for the quick-release slide fastener, then the structure remains simple, but the release operation becomes difficult and the textile may become dirty easily
Solution Approach 1:
A pulling member is introduced as an intermediary component between the user's hand and the slide fastener. This pulling member, which can be a strip of cloth or small hardware with a certain width, is provided on the slide fastener cloth strap or textile beside the tooth easy-release region. The pulling member serves as a dedicated interface for grasping and pulling, preventing direct contact between the user's hand and the textile, thus avoiding dirtiness while maintaining structural simplicity.
2Productivity
If the tooth easy-release region is designed for easy separation, then quick release is achieved, but the teeth may separate easily during normal use
Solution Approach 1:
The slide fastener teeth are designed with differentiated properties along their length. The tooth easy-release region (middle part) has reduced connection strength to enable quick release, while the tooth connection regions at both ends maintain strong connection for normal use stability. This local differentiation allows the same component to exhibit different mechanical properties in different zones, achieving both quick-release efficiency and operational reliability.
3Productivity
If no additional device is added to assist unzipping, then the structure remains simple, but the quick-release efficiency is reduced due to lack of focus in the release operation
Solution Approach 1:
The pulling member acts as a focused intermediary that concentrates the user's pulling force precisely at the tooth easy-release region. By providing a dedicated grasping element positioned beside the easy-release region, the design directs attention and force application to the correct location, significantly improving quick-release efficiency without requiring complex mechanisms or multiple components.

AI summary
A convenient and quick-release textile, a quick-release slide fastener being provided on the textile includes: a tooth easy-release region being provided on the teeth of the quick-release slide fastener. A pulling member is provided beside the tooth easy-release region. Quick positioners having a mutual positioning function are further provided on both the textile and the pulling member correspondingly. The quick positioner provided on the textile and the quick positioner provided on the pulling member are located on a same side of the quick-release slide fastener, or separately on two sides of the quick-release slide fastener. In this way, the pulling member textile is held easily and covers the tooth easy-release region, thus preventing the tooth easy-release region from separating due to the impact of the unnecessary external force.
