Tamperproof Wire Cap Rack Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tamper-evident solutions for packaging, such as retractable sleeves and detachable plastic accessories, are easily replicable by fraudsters and often distort the aesthetic appearance after opening, making it difficult to ensure inviolability and authenticity before first use.
Innovation Solution
A device comprising a vertical strap with four arms and a self-tightening collar forms a visible muzzle that irreversibly secures the primary packaging until first use, allowing complete opening by a detachable tab, ensuring the packaging regains its original appearance and aesthetic while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a retractable sleeve made of thin film is used to ensure tamper-evident function, then the inviolability before first use is ensured, but the protection is easily copied and replaced identically by fraudsters
Solution Approach 1:
The device is divided into multiple independent components: a cage with arms, a collar with rack mechanism, and a detachable tab. These segmented parts work together to create a tamper-evident system that is more difficult to replicate than a simple retractable sleeve, while maintaining the inviolability function.
Solution Approach 2:
The rack and pinion mechanism acts as an intermediary between the collar and the cage arms, creating a mechanical interlocking system that prevents unauthorized removal or replacement. This intermediate mechanism adds complexity that deters fraudsters while preserving the tamper-evident functionality.
2Reliability
If a detachable plastic accessory integrating primary packaging is used, then the inviolability is ensured, but the aesthetic appearance is distorted by residual technical components after opening
Solution Approach 1:
The detachable tab is designed to be completely removed from the collar after use. When the tab is pulled, it takes with it the entire collar assembly, leaving no residual technical components on the primary packaging. This extraction principle ensures that the packaging regains its original aesthetic appearance after opening.
Solution Approach 2:
The collar and tab assembly is designed as a disposable component that is discarded after serving its tamper-evident function. The mechanism allows the tab to be pulled away, taking the collar with it, so that no ugly residuals remain on the packaging. The primary packaging is recovered in its original aesthetic state.
3Reliability
If a visible muzzle device is used to guarantee inviolability, then the authenticity is guaranteed, but the device complexity increases
Solution Approach 1:
The cage, collar, and tab are merged into a single integrated device that functions as a unified tamper-evident system. The cage arms are connected to the collar through the rack mechanism, and the tab is integrated into the collar structure. This merging reduces the number of separate components that need to be assembled and managed, simplifying the overall system despite its enhanced functionality.
Solution Approach 2:
The device performs multiple functions: it provides tamper evidence, ensures authenticity, and maintains aesthetic appearance. The rack and pinion mechanism serves both as a locking mechanism and as a guide for the tab removal. The cage structure both protects the stopper and provides the visual indication of tampering. This multi-functionality reduces the need for additional separate components.

AI summary
The invention relates to a visible device for guaranteeing that a first packaging has not been tampered with before first use. According to the invention, said device comprises a first vertical strap (1) having four arms, each having an oriented rack (3) on which a movable collar (2) is positioned horizontally at 90° and at a desired height, wherein said collar is provided, on the inside thereof, with a male (4) and female (6) non-return rack. When the collar (2) is concentrically tightened to the fullest extent thereof, the device (1, 2) is tensioned and simultaneously flattened against the primary package while irreversibly confining the latter, the deliberate destruction of the device being enabled by a detachable tab (7, 10).
