External Lock Body With Push-In Handle Direction Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks are inconvenient for users with different hand usage habits as the handle's mounting orientation cannot be changed after assembly, and the handle is riveted to the box body, making it unsuitable for left-handed users.
Innovation Solution
A lock body with a quick assembly mechanism featuring a rotating part, limiting ring groove, and push-in member allows the handle to be easily assembled and disassembled, enabling the handle's direction to be adjusted according to user preference, using rolling friction and synchronized rotation to achieve axial limiting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the handle is riveted to the box body with fixed mounting orientation, then the structural strength and stability are improved, but the adaptability for different hand usage habits deteriorates
Solution Approach 1:
The handle mounting structure transitions from a fixed rigid connection to a dynamic adjustable system. The handle can be rotated to different orientations (e.g., horizontal or vertical) and locked in place, allowing the same lock body to adapt to different hand usage habits while maintaining structural strength through the locking mechanism.
Solution Approach 2:
The handle assembly is divided into separable components: the handle body, the mounting seat, and the limiting body. This segmentation allows the handle to be disassembled, reoriented, and reassembled in different configurations, providing adaptability while maintaining strength through proper reconnection.
2Stability of the object's composition
If the handle is fixedly mounted to the box body, then the assembly stability is improved, but the ease of operation for adjustment deteriorates
Solution Approach 1:
The mounting seat includes a pre-configured limiting ring groove and limiting body that enable easy adjustment. The limiting body can be pushed into the limiting ring groove to lock the handle in a desired orientation, and the structure is designed so that these components are readily accessible and easy to manipulate during installation and adjustment.
Solution Approach 2:
The limiting body acts as an intermediary element between the handle and the mounting seat. It provides a simple mechanical interface for locking the handle in place without requiring complex fastening mechanisms, making both the assembly stable and the adjustment easy when needed.
3Ease of operation
If a quick assembly mechanism with rotating part and limiting body is introduced, then the ease of assembly and adaptability are improved, but the device complexity increases
Solution Approach 1:
The quick assembly mechanism merges multiple functions into integrated components: the limiting body serves both as a positioning element and a locking mechanism; the mounting seat combines the rotation function with the limiting groove structure. This merging reduces the number of separate parts and simplifies the assembly process despite the added functionality.
Solution Approach 2:
The quick assembly mechanism is designed to be self-locking through the interaction between the limiting body and the limiting ring groove. Once the handle is rotated to the desired orientation and the limiting body is pushed into the groove, the structure automatically locks in place without requiring additional fastening operations, making assembly easy while keeping the mechanism relatively simple.
