Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condoms face issues with slippage and breakage due to incorrect fit, discomfort, and limited universality, which can lead to increased incidence of unwanted conception and transmission of sexually transmitted infections (STIs), especially in scenarios where users have limited access to diverse options.
Innovation Solution
A condom design featuring a continuous elastic tubular wall with a teat that can be partially or fully retained inside, a thicker base bead with looped projections for stress relief, internal baffles for seminal fluid retention, and a complementary fluid delivery system, along with angled contraction features to enhance fit and reduce slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If condom wall thickness is increased to reduce breakage risk, then barrier integrity improves, but sensation and fit accommodation deteriorate
Solution Approach 1:
The condom incorporates localized thicker regions at the base bead and distal end to provide enhanced strength where needed for preventing breakage and slippage, while maintaining thinner wall thickness in the main body to preserve sensation and flexibility. This non-uniform thickness distribution resolves the contradiction by applying material only where structurally necessary.
2Adaptability or versatility
If condom is designed for universal fit to accommodate diverse users, then accessibility improves, but fit precision and comfort deteriorate
Solution Approach 1:
The condom employs an elastic material composition and dynamic structural features including a flexible base bead with looped projections that can deform and adapt to different penis sizes and shapes. The elastic properties allow the condom to dynamically adjust its fit rather than relying on a fixed geometric design, thereby achieving universal applicability without sacrificing comfort.
3Ease of operation
If lubrication is increased to reduce friction and improve comfort, then ease of use improves, but risk of slippage increases
Solution Approach 1:
The condom incorporates localized friction-enhancing features such as ribs, dots, or textured patterns on the external surface in specific regions to provide grip and prevent slippage, while maintaining smooth internal surfaces for comfort. The base bead structure also provides mechanical interlocking to counteract slippage risk introduced by lubrication.
4Reliability
If base bead is thickened to prevent slippage and improve retention, then reliability improves, but comfort and stress distribution deteriorate
Solution Approach 1:
The base bead is segmented into multiple looped projections rather than a continuous thick ring. This segmentation distributes the constriction force across multiple discrete contact points, reducing localized stress and discomfort while maintaining overall retention effectiveness. The loops can also deform independently to adapt to different anatomies.
5Ease of operation
If condom material is made thinner to maintain sensitivity, then sensation improves, but risk of breakage and tear increases
Solution Approach 1:
The condom utilizes composite material formulations combining latex or polyisoprene with reinforcing agents, plasticizers, and curing additives to achieve high tensile strength and elasticity in thin walls. The material composition is engineered to provide breakage resistance comparable to thicker materials while maintaining the sensitivity benefits of thin construction.

AI summary
A condom comprising a continuous elastic tubular wall with a closed distal end and an open proximal end and further improving features. In one embodiment the condom further comprises a teat at the closed distal end, wherein the teat comprises a neck and a head, and wherein in use, the teat is retained partially or fully inside of the continuous elastic tubular wall, and the teat forms a chamber that is tillable with a fluid or phase change formulation which is released externally in use.
