Disposable Anti-tampering Lock Catch with Integrated Tearing Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable lock catches with anti-tampering features either require specialized tools for opening, result in environmentally unfriendly debris, or have complex structures with high manufacturing costs, and lack clear indication of their opened state.
Innovation Solution
A disposable anti-tampering lock catch with a simple, one-piece design featuring a main tearing structure and an auxiliary tearing arm that deforms upon opening, ensuring the tearing components remain attached and are made of high-strength plastic, allowing for easy operation without tools and clear visual indication of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional disposable lock catches are used, then anti-tampering effect is achieved, but tearing pieces drop into the box causing environmental pollution and recovery difficulties
Solution Approach 1:
The patent merges the tearing piece with the lock catch body through a connecting structure. When the lock catch is damaged to achieve anti-tampering effect, the tearing piece remains connected to the main body rather than scattering, thus maintaining reliability while eliminating environmental pollution from scattered debris.
Solution Approach 2:
The design enables the tearing piece to be recovered along with the lock catch body after use. The connecting structure ensures that when the lock catch is removed from the box, the tearing piece is retained, facilitating easy recovery and disposal as a single unit rather than scattered fragments.
2Object-affected harmful factors
If lock catches with complex structures are used, then anti-tampering effect is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent combines multiple functions into a single integrated structure. The lock catch body, tearing piece, and connecting structure form a unified component that provides anti-tampering protection without requiring multiple separate parts, thus reducing device complexity while maintaining security effectiveness.
Solution Approach 2:
The lock catch structure serves multiple functions simultaneously: the main body provides locking, the tearing piece provides visual indication and tamper evidence, and the connecting structure ensures both remain together. This multi-functionality in a single structure reduces overall complexity compared to separate components.
3Object-affected harmful factors
If lock catches requiring dedicated tools for opening are used, then anti-tampering effect is improved, but ease of operation deteriorates
Solution Approach 1:
The lock catch is designed to be opened by hand without requiring dedicated tools. The structure allows users to easily grasp and remove the lock catch from the box opening, making the operation self-service and convenient while still providing effective anti-tampering protection through the disposable nature of the component.

AI summary
Disclosed is a disposable anti-tampering lock catch. The disposable anti-tampering lock catch is an integrated piece and comprises a handle (101), a main tearing portion (103), a locking portion (104), a limiting portion (102) and an auxiliary tearing arm (105). A first tearing structure (1031) which cannot be restored after being torn is arranged on the main tearing portion (103). The auxiliary tearing arm (105) is provided with a second tearing structure (1051), wherein when the disposable anti-tampering lock catch is opened, both the first tearing structure (1031) and the second tearing structure (1051) are torn, and the shape of the auxiliary tearing arm (105) is deformed after being torn and cannot be reset.
