Zip Slider Structure with Elastic Tab-Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing zip slider structures have complex designs and fail to securely engage the sleeve and circle on the hook strip, leading to disengagement during user movement or jumping, as seen in the TW558966 patent.
Innovation Solution
A zip slider structure comprising a slider body, an elastic tab-holder, and a pull-tab with a pivot portion arranged between the tab-holder and slider body, featuring a stopping end on the tab-holder to prevent disengagement, and an attaching member with a securing bump to secure the tab-holder to the slider body, utilizing press punching and bending processes for assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the zip slider structure uses a simple arrangement without additional securing components, then the device complexity is reduced, but the reliability of engagement is worsened as the slider body may disengage during user movement or jumping
Solution Approach 1:
The tab-holder is divided into multiple functional segments: a body portion for housing, a first bending portion with slot for joining the pull-tab, a second bending portion with holding end for joining the slider body, and an attaching member with securing bump for anchoring to the slider body. This segmentation allows each part to perform its specific function while maintaining overall simplicity
Solution Approach 2:
The pull-tab is positioned and nested between the tab-holder and the slider body, with the pivot portion arranged in the space between these components. The attaching member with securing bump nests into the slider body structure, creating a compact integrated assembly that prevents disengagement without adding external complexity
2Manufacturing precision
If the zip slider structure uses traditional stamping process to engage the pull-tab with the slider body, then the manufacturing precision is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The tab-holder is designed as an elastic component that self-secures the pull-tab through its elastic property. The attaching member with securing bump automatically anchors to the slider body through elastic deformation and engagement, eliminating the need for separate stamping processes or additional fastening operations
Solution Approach 2:
The tab-holder utilizes elastic parameter changes through its material property, allowing it to deform and secure the pull-tab without permanent deformation or complex assembly. The elastic property enables the component to maintain engagement while accommodating manufacturing tolerances
3Ease of manufacture
If the zip slider structure lacks a stopping end on the tab-holder, then the ease of manufacture is improved, but the reliability is worsened as the structure cannot limit the positions and may disengage during movement
Solution Approach 1:
The stopping end is pre-formed on the tab-holder during the elastic component manufacturing process. This preliminary feature is designed to engage with the slider body structure in advance, preventing disengagement before it can occur during use, while requiring no additional assembly steps
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 solution effectively prevents the zip slider structure from disengaging during user movement or jumping by securely attaching the tab-holder to the slider body, ensuring the serrated structures remain engaged, enhancing the structural integrity and usability.
Implementation Method 1
The elastic tab-holder (2) is made from a material with elastic property or other elastic materials with elastic property and hence, the elastic property of the elastic tab-holder (2) may secure the elastic tab-holder (2) on the slider body (1)
