Condom Dispenser with Frangible Seal and Extractor Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condoms are difficult to open and wear due to their mechanical strength, which discourages their use and interferes with intimacy, as they require significant force and skill to extract and apply correctly, often causing anxiety about losing an erection.
Innovation Solution
A box-shaped case with a pusher and extractor mechanism that automates the opening and extraction of condoms, reducing the mechanical strength of individual packages and allowing simple, immediate access to a ready-to-use condom, supported by a frangible protective film and support frame for easy application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If condoms are packaged in single-use packages with good mechanical strength to protect from damage, then protection reliability is improved, but opening difficulty increases
Solution Approach 1:
The single-use package is segmented into a rigid outer casing for protection and a frangible inner seal for easy opening. The frangible seal is designed to break at specific weak points when force is applied, allowing the condom to be extracted without damaging it. This segmentation resolves the contradiction by separating the protection function (rigid casing) from the opening function (frangible seal).
Solution Approach 2:
The package design incorporates materials with different mechanical properties - a rigid casing with high strength for protection, and a frangible seal with controlled weakness for easy opening. By changing the material parameters locally within the package structure, the system achieves both high protection reliability and ease of opening.
2Reliability
If significant force is required to open the package, then protection reliability is improved, but ease of operation worsens
Solution Approach 1:
The frangible seal is pre-designed with weak points that will break when minimal force is applied in the correct direction. This preliminary preparation of the opening mechanism allows the condom to be extracted with simple gestures without requiring significant force, while the rigid casing maintains protection during storage.
3Reliability
If complex operations are required to extract and wear the condom, then protection reliability is improved, but ease of operation worsens
Solution Approach 1:
The package design includes features that guide the user through the extraction and application process. The frangible seal breaks to automatically expose the condom in the correct orientation, and the rigid casing provides structural support during extraction. This self-guiding mechanism ensures correct application while maintaining operational simplicity.
4Strength
If the package requires significant force to open, then mechanical strength is improved, but psychological resistance increases
Solution Approach 1:
By segmenting the package into a strong rigid casing and a weak frangible seal, the design creates a clear distinction between the protection function (strong casing) and the opening function (weak seal). This allows the package to maintain high mechanical strength for protection while requiring minimal force for opening, thereby reducing psychological resistance.

AI summary
A case for the storage and easy wearing of condoms emprises-includes a box-shaped casing defining a containment chamber configured to accommodate a plurality of condoms arranged in respective flattened single-use packages arranged to form a stack. A pusher operates in the containment chamber so that a terminal single-use package of said stack is held against a bottom wall of the chamber itself. An extractor movable between a waiting position in which it engages the terminal single-use package inside the containment chamber and an extracted position in which the terminal single-use package is extracted through an outlet slot arranged in proximity to the bottom wall to expose the respective condom outside the box-shaped casing, in a use condition suitable for wearing.
