Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door and window locks are either structurally simple but costly and difficult to mount, or complex and expensive with many transmission parts, limiting their usability and convenience.
Innovation Solution
A side-hung door or window single latch lock with a simplified structure, featuring a first and second lock body, a latch assembly, and an elastic locking and controlling mechanism, allowing for easy assembly and operation, with fewer transmission components and a double lock switch for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional insertion-core lock bodies or ball-shaped lock bodies are used, then the structure is simple and cost is low, but the door body structure must be destroyed and mounting is troublesome and time-consuming
Solution Approach 1:
The lock is divided into separate components: a lock body that can be mounted without destroying the door, a latch assembly, and a hinge assembly. This segmentation allows the lock to be installed as a complete unit without requiring grooves to be cut into the door body, thus resolving the contradiction between simple structure and easy mounting.
Solution Approach 2:
The latch assembly is nested within the lock body, and the hinge assembly is integrated into the lock body structure. This nesting allows the lock to function as a complete unit that can be mounted without modifying the door body, maintaining structural simplicity while enabling easy installation.
2Ease of manufacture
If current side-hung door or window locks are used, then the door body structure is not destroyed and mounting is simpler, but the structure is complicated and includes too many transmission parts
Solution Approach 1:
The invention extracts and eliminates unnecessary transmission parts from the lock system. Instead of using multiple transmission components to control the latch, the design uses a direct linkage where the handle operates the latch assembly through a simplified mechanical connection, reducing the number of parts while maintaining functionality.
Solution Approach 2:
The lock body, latch assembly, and hinge assembly are merged into an integrated unit that can be mounted as a single component. This merging eliminates the need for separate transmission mechanisms and reduces overall structural complexity while maintaining ease of mounting.
3Ease of manufacture
If current side-hung door or window locks with many transmission parts are used, then mounting is simpler, but operation is inconvenient and cost is high
Solution Approach 1:
The latch assembly is designed to automatically engage and disengage through a self-servicing mechanism. When the handle is operated, the latch assembly automatically moves to lock or unlock position without requiring additional transmission parts or complex operations, thus improving ease of operation while maintaining simple mounting.

Implementation Method 1
an elastic clutch-type lock core telescopically encapsulated in the first lock body
Implementation Method 2
a first clutch piece movably embedded in a main body of the elastic clutch-type lock core
Implementation Method 3
a first return spring disposed at a proximal end of a rotating and connecting position of the latch, with both ends thereof respectively abutting against the internal cavity of the first lock body and the latch
Implementation Method 4
a second return spring which is movably provided around the second clutch piece and which both ends respectively abut against and cooperating with an internal chamber of the elastic clutch-type lock core main body and the ""-shaped boss of the second clutch piece
