Zipper Guide Wedge for Closing Tight Compression Garments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Zippers on tight-fitting garments, such as compression hoses, are difficult to close due to high stresses, often requiring assistance and risking damage to the zipper components.
Innovation Solution
A wedge-shaped zipper assist device with diverging guide channels and a handle allows for manual operation, reducing the zipper closing angle and distributing forces evenly across the tracks, enabling easy closure without additional help.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional zippers are used on tight-fitting garments, then the garment provides necessary compression, but the zipper becomes difficult to close and requires assistance
Solution Approach 1:
A zipper assist device is introduced as an intermediary tool between the user and the zipper. The device includes a body with guide channels that receive the zipper tracks, and a handle that transmits user pulling force to the zipper slider, enabling independent operation of zippers on tight-fitting garments
2Productivity
If greater force is applied to close the zipper, then the zipper can be closed, but the risk of damage to zipper components increases
Solution Approach 1:
The zipper closing angle is changed from a large acute angle to a smaller angle through the guide channels. This parameter change reduces the lateral stress on zipper tracks and components while still achieving effective zipper closure, preventing damage to zipper components
3Ease of operation
If assistance from another person is used to close the zipper, then the zipper can be closed successfully, but the process becomes more complex and time-consuming
Solution Approach 1:
The zipper assist device enables the user to close the zipper independently without requiring assistance from another person. The device transforms the closing action into a simple pulling motion on the handle, making the process self-service and eliminating the need for additional helpers
4Force
If tools like pliers are used to facilitate zipper movement, then greater force can be applied, but the likelihood of damage to zipper components increases
Solution Approach 1:
Instead of applying greater force directly, the guide channels change the zipper closing angle parameter, reducing lateral stress on components. The handle provides mechanical advantage for force application in a controlled manner, avoiding the damage risk associated with tools like pliers

AI summary
A device for assisting in opening and closing a zipper is provided. The device includes a body having first and second diverging guide channels having mutually oriented guide angles for receiving the respective zipper tracks for sliding, non- interlocking movement of the zipper tracks through the guide channels in advance of the zipper slider for reducing the closure angle of the zipper tracks in advance of the zipper slider to correspond to the guide angle of the guide channels, and a handle carried by the body for permitting manual pulling movement of the body along at least a portion of the length of the zipper and generally positioned in a coextensive orientation in relation to a pull tab of the zipper slider such that an operator can simultaneously grasp the pull tab of the zipper slider and the handle while sliding the zipper slider in the closing direction.
