Compression Stocking Zipper With Open Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression stockings with zippers are difficult to manage after exercise due to sweaty fingers reducing friction, making it hard to move the slider and zip up the stocking.
Innovation Solution
A compression stocking with a zipper design featuring different inner diameters at both ends, a V-shaped zipper teeth arrangement, an open member for easy finger access, and a tension part to prevent excessive opening, along with an easy-pull component for effective zipping without pinching the slider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional zipper with a small slider is used, then the compression stocking can be firmly pressed against the leg, but it becomes difficult to move the zipper when fingers are sweaty after exercise
Solution Approach 1:
The patent introduces an open member (ring or loop structure) as an intermediary between the user's fingers and the slider. This open member serves as a mediator that allows users to pull the zipper by inserting fingers through the ring rather than directly pinching the small slider, solving the problem of difficult zipper operation when fingers are sweaty while maintaining the firm pressing effect of the original zipper design
Solution Approach 2:
The patent separates the gripping function from the slider by introducing the open member. The open member becomes an independent component that handles the gripping interaction, while the slider maintains its original function of engaging the zipper teeth. This segmentation allows the slider to remain small and effective for pressing while the open member provides ease of operation
2Reliability
If the tube body is made with tight fit for compression effect, then the compression stocking provides effective pressure, but it becomes difficult to put on and take off
Solution Approach 1:
The patent applies dynamic design to the zipper system, allowing the tube body to transition between two states: when the zipper is open, the tube body remains loose and easy to put on; when the zipper is closed, the tube body becomes tight and provides compression effect. This dynamic state change resolves the contradiction between compression effectiveness and ease of wear/removal

AI summary
A tube of compression stocking with zipper includes a tube body and a zipper on the tube body to press the tube body against the leg, the zipper includes two zipper teeth tapes and a slider to make the two zipper teeth tapes mesh with each other, the slider is provided with an open member to be passed through by fingers, the two zipper teeth tapes extend from an end of the tube body with a smaller inner diameter to another end and are arranged in a V-shape, an end of the two zipper teeth tapes with a greater interval is positioned on the end of the tube body with a greater inner diameter, and a difference between a maximum inner diameter of the tube body and a maximum interval of the two zipper teeth tapes is greater than a minimum inner diameter of the tube body.
