Multi-Drawer Locking Buckle for Simultaneous Lock and Unlock Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drawer boxes require cumbersome and inconvenient individual locking and unlocking of each drawer, which becomes impractical as the number of drawers increases, necessitating a solution to reduce user operation steps.
Innovation Solution
A locking buckle structure with a push lock body and multiple locking tongues, equipped with elastic members and locking blocks, allows simultaneous locking and unlocking of multiple drawers, with the option for individual drawer control, using a single operating mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual locking is used for each drawer, then each drawer can be locked independently, but the number of operation steps increases significantly when multiple drawers need to be locked
Solution Approach 1:
The patent combines multiple locking functions into a single locking buckle structure. The locking buckle includes a locking block that can simultaneously engage with multiple locking grooves on different drawers through a single pushing motion, merging what would otherwise require multiple separate locking operations into one unified action.
Solution Approach 2:
The locking buckle structure is designed with multi-functionality to handle both individual and multiple drawer locking needs. By incorporating a pushing mechanism that can selectively engage different drawers based on their position, the single locking buckle structure provides universal locking capability for any combination of drawers.
2Ease of operation
If a single locking mechanism controls multiple drawers, then operation steps are reduced, but the ability to lock individual drawers independently is lost
Solution Approach 1:
The locking mechanism is segmented into multiple independent locking grooves, each corresponding to a specific drawer. The locking block can selectively engage with any combination of these grooves based on drawer position, allowing the single locking buckle to provide both bulk and individual locking functionality through its segmented structure.
Solution Approach 2:
The locking mechanism incorporates dynamic elements including elastic members that allow the locking block to automatically adjust its position. When a drawer is pulled out, the elastic member enables the locking block to move and selectively disengage from specific locking grooves, providing dynamic individual drawer unlocking while maintaining control over multiple drawers.
3Reliability
If manual locking of each drawer is required, then security is maintained, but user time and effort increase
Solution Approach 1:
The locking grooves are pre-positioned on each drawer at specific locations. When drawers are installed in the drawer box, their locking grooves are automatically aligned with the locking block's engagement positions. This preliminary arrangement of locking components eliminates the need for manual alignment during locking operations, reducing time while maintaining security.
Solution Approach 2:
The elastic member provides self-service functionality by automatically returning the locking block to its engaged position after unlocking. When the user releases the locking buckle, the elastic member automatically pushes the locking block back into the locking grooves, providing automatic re-locking without requiring user intervention, thus saving time while maintaining security.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution significantly reduces user operation steps by enabling multiple drawers to be locked and unlocked simultaneously, while also allowing for easy individual drawer locking without additional operation, maintaining the locked position automatically.
Implementation Method 1
a first elastic member located between the push lock body and each locking tongue, which automatically ejects the locking tongue relative to the push lock body
Data Source
AI summary
A push lock body; multiple locking tongues set on the push lock body, wherein the locking buckle structure has a locking/unlocking position, and the each of the multiple drawers has a closing and pulling position; wherein when the locking buckle structure is in the locked position, the drawers are in the closed position and locked with the corresponding locking tongue, and wherein when the drawer is in the pulled out position, the drawers can be moved to the closed position and locked with the corresponding locking tongue; and wherein when the locking buckle structure is in the unlocked position, the drawers located in the closed, pulled out position are all unlocked with the corresponding locking tongue.
