Tamper-Evident Child-Proof Coupling System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child-proof containers face limitations such as complex structures, high production costs, and lack of tamper-evidence, making them inflexible and expensive to produce, while also losing their child-proof functionality after initial opening.
Innovation Solution
A tamper-evident child-proof coupling system with a stable structure, capable of multiple openings and closures, featuring a first and second base portion with coupling portions that engage in a priming condition, a slit for an opening device, and a closing septum that irreversibly changes position to signal attempts to open or tamper with the system, allowing for standard machinery production and maintaining child-proof integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional child-proof containers use complex engagement systems between case and blister, then child-proof functionality is achieved, but production cost and structural complexity increase
Solution Approach 1:
The container system is divided into two independent functional parts: a case with a closing system and a blister with a coupling system. The closing system includes a coupling portion that engages with the blister's coupling portion, while the blister is secured through a separate locking mechanism. This segmentation allows each part to be optimized independently, reducing overall structural complexity while maintaining child-proof functionality.
Solution Approach 2:
The invention extracts the child-proof locking function from the traditional case-blister integration and places it into a separate closing system with a coupling portion. This extracted coupling system can be independently manufactured and attached to the case, simplifying the overall structure and enabling standard production methods while preserving the secure closure function.
2Reliability
If conventional child-proof containers use specialized production methods, then secure closure is achieved, but manufacturing flexibility and cost-effectiveness decrease
Solution Approach 1:
The closing system with the coupling portion is designed to be universal and adaptable to different blister types and container configurations. The coupling portion can engage with various blister coupling portions using the same basic mechanism, allowing standard production machinery to manufacture different variants without requiring specialized equipment for each design.
Solution Approach 2:
The invention allows for parameter changes in the coupling system design while maintaining the same fundamental engagement principle. The coupling portion dimensions, shape, and engagement force can be adjusted to suit different applications, enabling flexible manufacturing with standard equipment while achieving secure closure across various product types.
3Ease of operation
If conventional containers allow initial opening by adults, then accessibility is improved, but child-proof functionality is lost after opening
Solution Approach 1:
The closing system is designed with a preliminary action mechanism where the coupling portion must be deliberately disengaged before the blister can be removed. This preliminary disengagement step serves as a deliberate action that indicates intentional opening, and the system maintains its secure design features even after opening, preventing casual access by children while allowing controlled adult access.
4Device complexity
If conventional containers lack tamper-evidence features, then structural simplicity is maintained, but security and trustworthiness decrease
Solution Approach 1:
The invention incorporates a tamper-evident coating on the coupling portion that changes color or shows visible signs of tampering when the coupling system is compromised or opened improperly. This color change feature provides clear visual evidence of tampering without significantly increasing the structural complexity of the container system.

AI summary
The present disclosure relates to a tamper-evident and child-proof coupling system. The coupling system includes a first base portion, a second base portion, a slit, and a closing septum. The first base portion includes a first coupling portion. The second base portion includes a second coupling portion. The first and second coupling portions are configured to define a priming configuration of the coupling system when the first and second coupling portion are engaged to each other. The slit is defined on the first base portion or the second base portion and is configured to receive an opening device. The opening device is configured to disengage the first and second coupling portions. The closing septum is adjustable to a first or second configuration. In the first configuration, the closing septum occludes the slit. In the second configuration, the closing septum is configured to expose the slit.
