Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing zipper sliders have complex structures, leading to inconvenient installation and high production costs, making them unsuitable for mass production.
Innovation Solution
A simplified slider design integrating the pull-tab with the connecting shaft, featuring a spring mounting part and locking part, with a cambered surface and U-shaped groove for easy assembly and reduced friction, allowing for a more straightforward assembly process and lower production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional slider structure with separate pull-tab and connecting shaft is used, then the slider has sufficient strength and reliability, but the structure becomes complex, installation becomes inconvenient, and production cost increases
Solution Approach 1:
The patent combines the pull-tab and connecting shaft into a single integrated component. The pull-tab body directly forms the connecting shaft structure, eliminating the need for separate parts and complex assembly processes while maintaining the mechanical functionality of both components
Solution Approach 2:
The integrated pull-tab connecting shaft structure performs multiple functions simultaneously: it serves as the pulling mechanism, the connecting element between slider blades, and the rotational joint. This multi-functionality reduces the overall number of components needed in the slider assembly
2Productivity
If a traditional slider with multiple separate components is used, then the slider can be designed with optimized individual parts, but the installation process becomes time-consuming and productivity decreases
Solution Approach 1:
By merging the pull-tab and connecting shaft into one integrated component manufactured as a single piece, the patent eliminates multiple assembly steps. The integrated structure can be installed as one unit, significantly reducing assembly time and improving productivity
Solution Approach 2:
The connecting shaft is pre-formed as an integral part of the pull-tab body during manufacturing. This preliminary formation of the connecting structure eliminates the need for separate machining or assembly operations during final installation, streamlining the manufacturing process
3Ease of manufacture
If a complex slider structure with multiple parts is used, then each part can be optimized for specific functions, but the production cost increases due to multiple manufacturing processes and assembly operations
Solution Approach 1:
The patent merges multiple components (pull-tab body and connecting shaft) into a single integrated part that can be manufactured in one process. This reduction in component count directly lowers production costs by eliminating multiple manufacturing operations, material handling, and quality inspection steps for separate parts
Solution Approach 2:
The integrated structure performs multiple functions within a single component, reducing the total material usage and manufacturing complexity. The universal design allows one component to replace several specialized parts, simplifying the supply chain and reducing inventory costs
