Flexible Adhesive Patch for Bacterial Barrier During Intimacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions lack effective preventive measures to minimize the transmission of bacteria from the anus and surrounding skin portion during sexual activities, leading to urinary tract and bladder infections, with existing remedies often relying on antibiotics that can cause resistance and disrupt the immune system's balance.
Innovation Solution
A patch with a flexible, thin, and transparent carrier layer and a strong adhesive layer designed for easy application and removal, providing temporary sealing of the anal orifice and surrounding skin portion to prevent bacterial transfer, featuring a tab for finger application and a design that allows for discreet use without hindering sexual activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a patch is applied to seal the anal orifice during sexual activities, then bacterial transfer is prevented and urinary tract infections are minimized, but the patch must be thin and flexible enough not to hinder sexual activities
Solution Approach 1:
The patch uses a thin film carrier layer (5-5000 μm thickness) that is flexible and can conform to the body contour, allowing it to provide bacterial protection while remaining compatible with sexual activities. The thin film structure ensures the patch does not hinder movement or comfort during intimate moments.
Solution Approach 2:
The patch is designed to be dynamic rather than rigid, with a flexible carrier layer that can adapt to body movements and changes in position during sexual activities. This dynamic design allows the patch to maintain its sealing function while moving with the body, preventing bacterial transfer without restricting natural motion.
2Reliability
If a strong adhesive layer is used to ensure the patch stays in place, then sealing reliability is improved, but the adhesive must be gentle enough for easy removal without skin damage
Solution Approach 1:
The adhesive layer uses pressure-sensitive adhesive technology that changes its bonding parameters based on applied pressure. During application, the adhesive bonds strongly to ensure reliable sealing, but during removal, the adhesive can be gently peeled off without causing skin damage, achieving both stable sealing and easy removal.
3Ease of manufacture
If the patch is made transparent to be discreet, then aesthetic appearance is improved, but the material must still provide effective bacterial barrier function
Solution Approach 1:
The transparent patch uses a thin film carrier layer that allows light transmission for aesthetic discretion while maintaining its barrier function. The thin film structure, despite being transparent and flexible, provides effective protection against bacterial transfer by creating a continuous seal over the anal orifice and surrounding skin.

Function Achieved in This Case
The patch effectively minimizes the risk of urinary tract and bladder infections by creating a reliable, temporary barrier against bacterial transfer, reducing the need for antibiotics and promoting a healthier immune system by preventing bacterial penetration during sexual activities.
