Bunion Patch Non-Stick Center Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bunion patches often cause discomfort and pain due to sticky centers that adhere to the sore area, double-layered designs that apply pressure, and difficulty in detachment, failing to provide a comfortable and effective solution for foot care.
Innovation Solution
A bunion patch with a non-stick, single-layer center design featuring a bottom layer that adheres to the skin and a top layer that covers the sensitive area without adhesive contact, allowing for easy application and removal, and optional detachable layers for medication access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the center of the bunion patch is made sticky to adhere to the sore area, then the patch stays in place, but it causes pain and discomfort to the sensitive area
Solution Approach 1:
The patch is divided into distinct functional zones: a non-stick center section that contacts the bunion, and peripheral adhesive sections that secure the patch to surrounding skin. This segmentation allows the patch to stay in place without the adhesive contacting the sensitive area, resolving the contradiction between adhesion and comfort.
Solution Approach 2:
Different regions of the patch have different adhesive properties: the center is non-adhesive to protect the bunion, while the edges are adhesive to secure the patch. This local differentiation of quality allows the patch to simultaneously achieve reliable attachment and avoid causing pain to the sensitive area.
2Object-affected harmful factors
If a double-layered center is used to prevent stickiness, then the center does not adhere to the skin, but it causes pressure and pain to the bunion
Solution Approach 1:
The adhesive material is completely removed from the center section of the patch. Instead of using a double-layered non-stick center that still exerts pressure, the invention extracts the adhesive property entirely from the area contacting the bunion, replacing it with a non-adhesive material that provides no pressure or discomfort.
3Reliability
If adhesive is applied to the center of the patch, then the patch adheres well to the skin, but it becomes difficult to detach and causes pain during removal
Solution Approach 1:
The patch is segmented into a non-adhesive center and adhesive periphery. This allows the patch to be easily detached from the sensitive bunion area while still maintaining secure attachment through the adhesive edges, resolving the contradiction between adhesion strength and ease of removal.
4Reliability
If medication is applied directly to the skin through the patch, then treatment is effective, but the sticky center adheres to the medication and skin making renewal difficult
Solution Approach 1:
The non-adhesive center creates a clean interface between the patch and the medicated area, allowing medication to be applied and renewed without the patch sticking to the skin or medication. This segmentation facilitates easy medication renewal while maintaining effective treatment delivery.

AI summary
Apparatus and systems are disclosed for covering and protecting sensitive, sore, upset, and/or wounded areas of skin such that the pad or patch applied to these areas cannot and will not stick to the sensitive areas while at the same time covering these areas, or such that the pad or patch applied to these areas will be used to directly deliver any desired medication to these sensitive areas while covering and protecting them.
