Cabinet locking device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cabinet locking devices are cumbersome due to complex latching mechanisms and bulky transmission mechanisms, occupying space and complicating the configuration of storage cabinets.
Innovation Solution
A cabinet locking device featuring a movable storage system with slide rails, a locking mechanism with a sliding member, interference member, and restriction mechanism, and a driving device with a traction mechanism and drawstring, allowing for efficient engagement and release of the locking mechanism without interfering with the storage device's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional locking device with latching mechanisms and transmission mechanism is used, then the locking function is achieved, but the configuration becomes complicated and occupies accommodation space inside the cabinet
Solution Approach 1:
The patent extracts and eliminates the complex transmission mechanism from the locking device. The locking mechanism directly acts on the drawer body without requiring intermediate transmission components, thereby simplifying the overall configuration while maintaining the locking function.
Solution Approach 2:
The locking mechanism is designed to perform multiple functions: it provides locking capability, guides the sliding motion through the restriction mechanism, and controls the engagement through the interference member. This multi-functionality reduces the need for separate components, simplifying the configuration.
2Reliability
If a conventional locking device with bulky transmission mechanism is used, then the locking function is achieved, but the accommodation space inside the cabinet is occupied
Solution Approach 1:
The patent removes the bulky transmission mechanism from the locking device, eliminating the space it would occupy within the cabinet. The simplified locking mechanism requires minimal space, thereby increasing the available accommodation space for storage purposes.
3Volume of stationary object
If a locking device with simple configuration is used, then the accommodation space is optimized, but the locking mechanism may interfere with the storage device's movement
Solution Approach 1:
The restriction mechanism is designed to dynamically guide the sliding member's displacement path. It allows free movement in the sliding direction while providing constraints in the perpendicular direction, ensuring the locking mechanism moves smoothly without interfering with the storage device's operation.
Solution Approach 2:
The restriction mechanism provides directional constraint: it restricts movement in the direction perpendicular to sliding while allowing free movement in the sliding direction. This localized quality of constraint ensures smooth operation without unnecessary interference.

AI summary
A cabinet locking device includes a cabinet body, a plurality of movable storage devices, a plurality of locking devices, and a driving device. The driving device is interlocked with the locking devices via a plurality of drawstrings. Each locking device includes a sliding member, an interference member disposed on the sliding member, and a restriction mechanism for guiding the sliding member. The driving device can drive the sliding member to move to an engaging portion or a released position. When the sliding member is moved to the engaged position, the interference member interferes with an engaging portion of the corresponding movable storage device such that the movable storage device cannot be opened. When the sliding member is moved to the released position, the interference member does not interfere with the engaging portion such that the movable storage device can be opened.
