Slide Fastener Slider with Fixed String for Remote Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide fasteners are cumbersome for remote operation, particularly when the slider is positioned in hard-to-reach areas, as the string must be drawn significantly to engage with the pull tab, leading to slow fastening and unfastening.
Innovation Solution
A slider design where a string with pull tabs is fixed to the body using separate members, including upper and lower blades with guide posts and fixture members, allowing direct force application and preventing string movement, enabling quick sliding and remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the string is allowed to move freely in the through-hole, then the slider structure is simple, but the slider cannot be quickly fastened and unfastened because the string must be drawn until the stopper or pull tab contacts the slider
Solution Approach 1:
The string is pre-fixed to the body at a predetermined position before use, eliminating the need to draw the string during operation. This preliminary positioning action enables immediate slider movement when the pull tab is pulled, resolving the contradiction between structural simplicity and fastening speed.
2Reliability
If the string is fixed to the body using a separate member, then the string can be securely fixed, but the device complexity increases
Solution Approach 1:
The fixation system is segmented into modular components: the body with opening, separate fixture members, and the string itself. This segmentation allows each component to perform its specific function independently while maintaining overall simplicity and reliability of the fixation system.
3Ease of manufacture
If the string is inserted through a longitudinally passing opening, then the string can be easily inserted, but the string may move freely causing operational delay
Solution Approach 1:
Fixture members act as intermediary elements between the string and the body. These intermediaries secure the string at the predetermined position within the opening, preventing free movement while maintaining easy insertion capability during manufacturing.

AI summary
A slider for a slide fastener is provided which is capable of quickly fastening and unfastening the slide fastener in a remote operation manner. A string having pull tabs on longitudinally opposite sides is fixed to a body of the slider for a slide fastener such that the string is not moved in the longitudinal direction.
