Invisible Zipper Slider With Friction-Suspended Puller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing invisible sliders with pullers for zippers leave processing marks and are prone to breakage due to direct contact during riveting, making them unsuitable for high-end products with strict appearance requirements.
Innovation Solution
An invisible slider design featuring a puller that uses an end pressing member riveted to a guide column, allowing arbitrary suspension without direct contact, utilizing frictional forces for rotation, and incorporating a positioning groove and recessed slots to facilitate riveting and prevent breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If claws are used to directly grip the rotating shaft of the puller to achieve arbitrary suspending, then the suspending effect is achieved, but processing marks and scratches appear on the puller surface during riveting
Solution Approach 1:
The patent introduces an intermediary component (the pressing member with pressing surface) between the riveting device and the puller. The pressing member receives the riveting force and transmits it to the puller through friction, eliminating direct contact between the riveting device and puller surface, thus preventing processing marks while maintaining the suspending function.
2Ease of operation
If direct riveting is performed on the puller to achieve gripping effect, then the suspending function is achieved, but the puller is prone to breakage during processing
Solution Approach 1:
The pressing member serves as a protective intermediary that distributes the riveting force over a larger area and prevents direct stress concentration on the puller. This intermediary structure reduces the risk of puller breakage during processing while maintaining the suspension function.
Solution Approach 2:
The pressing member acts as a cushioning element before the riveting force is applied to the puller. It absorbs and distributes the mechanical stress, preventing sudden stress concentration that could cause puller breakage during the riveting process.
3Shape
If the slider is made small to achieve invisible design, then the aesthetic appearance is improved, but the claws become smaller and more prone to breakage
Solution Approach 1:
The patent segments the slider structure into distinct functional components: the invisible slider body for aesthetic appearance and the separate pressing member assembly for mechanical strength. This segmentation allows the slider body to remain small and aesthetic while the pressing member provides the necessary structural robustness to prevent breakage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design avoids processing marks, enables large riveting portions for easier processing, reduces breakage risk, and accommodates various shaft sizes, suitable for high-end products with precise appearance demands.
Implementation Method 1
a frictional force is present between the rotating shaft of the puller and the pressing part and between the rotating shaft of the puller and the guide column, the frictional force allowing the puller to rotate to any angle to be suspended
