Drawer Lock Assembly With Perpendicular Dual-Bolt Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer lock assemblies often require complex mechanisms and multiple components, leading to inefficiencies and potential security vulnerabilities.
Innovation Solution
A drawer lock assembly with a housing, barrel, driver, and dual bolts that extend and retract perpendicular to each other, actuated by a locking actuation member, allowing for a simplified and secure locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional drawer lock assemblies use complex mechanisms and multiple components, then they may provide adequate security, but they increase device complexity and potential security vulnerabilities
Solution Approach 1:
The lock assembly is divided into distinct functional modules: a housing containing a driver, a bolt with gear teeth, and a separate cam mechanism. This segmentation allows each component to perform its specific function independently, reducing overall complexity while maintaining security through the coordinated action of simplified parts
Solution Approach 2:
The cam mechanism is extracted as a separate operational element that can rotate independently within the housing. By taking out the cam from the bolt structure and making it a distinct component, the design eliminates the need for complex internal mechanisms within the bolt itself, simplifying the overall assembly while preserving the locking function
2Reliability
If traditional drawer lock assemblies use multiple components, then they may provide adequate locking function, but they increase the number of parts and potential failure points
Solution Approach 1:
The housing simultaneously serves multiple functions: it contains the driver, guides the cam rotation, supports the bolt assembly, and provides the mounting structure for the entire lock. By merging these functions into a single housing component, the design reduces the total number of parts while maintaining reliable locking operation
Solution Approach 2:
The cam component performs multiple functions: it engages with the gear teeth on the bolt to control bolt movement, rotates within the housing to transition between locked and unlocked states, and works with the driver to provide the actuation mechanism. This multi-functionality reduces the need for separate components for each function

AI summary
A drawer lock assembly includes a housing; a barrel having a first end extending perpendicularly from a front face of the housing and a second end extending through a rear face of the housing; a locking actuation member disposed through the barrel; a driver disposed through the barrel to engage the locking actuation member; a first and second bolt, each bolt configured to engage the driver, where upon actuation of the driver via the locking actuation member, the first and second bolts move in opposite directions in a perpendicular arrangement relative to the barrel; and an end plate configured to retain the driver and the first and second bolts in the housing, wherein upon actuation of the locking actuation member by a key, the first and second bolts extend from the housing in a first position and at least partially retract within the housing in a second position.
