Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun containers with electric password locks are prone to malfunction, leading to potential emergencies when the locking mechanism cannot be opened, especially in critical situations.
Innovation Solution
A gun container with a double-coupling locking mechanism that includes a reciprocately-driving module controlled by an electric password switch and a mechanical backup system, allowing the container to be opened using a key if the electric system fails, featuring a movable shaft, locking tongue, and a pendulum arm mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an electric password lock is used for the gun container, then the ease of operation is improved, but the reliability deteriorates due to potential malfunction
Solution Approach 1:
The locking system is divided into two independent segments: an electric password lock mechanism and a mechanical key lock mechanism. Each segment can function independently, so if one fails, the other can still operate. The electric motor drives a first locking tongue through a gear system, while a separate key-driven second locking tongue provides mechanical backup, ensuring both ease of operation and reliability.
Solution Approach 2:
The system changes the operating parameter from purely electronic to a combination of electronic and mechanical. The electric password lock operates through electrical signals controlling a motor, while the mechanical key lock operates through physical key insertion and rotation. This dual-parameter approach ensures that if the electrical system fails, the mechanical system can still provide secure locking and unlocking.
2Reliability
If a mechanical key lock is added as backup, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The electric and mechanical locking mechanisms are merged into a single integrated lock assembly. Both the electric motor-driven locking tongue and the key-driven locking tongue are positioned within the same locking chamber and work on the same latch structure. This merging allows the system to achieve high reliability through redundancy while minimizing the increase in overall device complexity by sharing common structural elements.

AI summary
A gun container having a double-coupling locking mechanism includes a box body and a cover covering an opening of the box body. A mounting base is arranged in the box body and defines a mounting cavity; a movable shaft is received in the mounting cavity. A locking tongue is arranged at an end of the movable shaft; a reciprocately-driving module is controlled by an electric password switch module and is arranged to drive the movable shaft to move reciprocately; a locking core is perpendicular to the movable shaft and located at a front side of the movable shaft; the mounting base defines a slot in which a locking latch is inserted; the locking tongue is mated with the locking latch to lock the cover; the movable shaft or the locking tongue is fixedly arranged with an extension shaft, extending towards the locking core.
