Tamper-Evident Condom Packaging With Chemical Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tamper-evident packaging technologies do not effectively provide a clear indication of tampering through touch detectable formations that are absent before interaction, lacking a reliable method to ensure package integrity and detect unauthorized access.
Innovation Solution
A condom package design featuring a first and second barrier with a first substance and a condom partitioned from a second substance by the second barrier, where a chemical interaction between the substances forms touch detectable solid structures upon tampering, indicated by squishable gel-like globules, ensuring visible evidence of tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical indicators are used to detect tampering, then detection capability is improved, but the packaging structure becomes more complex
Solution Approach 1:
The patent utilizes changes in physical state (from liquid to solid) and chemical properties (reactivity) of the substances as parameters change upon tampering. The first substance and second substance are selected to undergo a detectable transformation when they interact, providing a reliable tamper indicator through parameter change rather than complex mechanical structures.
Solution Approach 2:
The patent employs composite packaging structures with multiple barriers (first barrier and second barrier) containing different substances. These composite materials provide both protective function and tamper detection capability, integrating multiple functions into a unified packaging system rather than adding separate complex detection devices.
2Reliability
If multiple barriers and substances are used to ensure package integrity, then reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The packaging is divided into segmented components (first barrier, second barrier, first substance, second substance) that can be manufactured separately and then assembled. This segmentation allows each component to be optimized for its specific function while simplifying the overall manufacturing process through modular construction.
Solution Approach 2:
The first substance and second substance are pre-positioned in their respective barriers during manufacturing, sealed in a predetermined arrangement. This preliminary action ensures that when the package is later tampered with, the substances will automatically interact to provide tamper evidence without requiring additional activation steps or complex assembly during use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The package provides a reliable and tactile indication of tampering through the formation of touch detectable solid structures, ensuring package integrity and user awareness of unauthorized access.
Implementation Method 1
causes a chemical interaction between two substances of the packaging. The chemical interaction produces a plurality of touch detectible formations absent from the packaging prior to the interaction

AI summary
A condom package has a first barrier having a first surface and an oppositely facing second surface. A second barrier of the package has a first and oppositely facing second surface. A first substance is between the first barrier first surface and second barrier second surface. A second substance and a condom are partitioned from the first substance and first barrier by the second barrier. The second substance and condom are in a bounded area delimited by the second barrier first surface.
