Lock Cylinder Fixing Plate Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks with high flexibility of use are complex, costly, and non-compact due to additional components required for adjusting handing and entry, complicating logistics and assembly.
Innovation Solution
A lock design featuring a plate for fixing the cylinder on the outer side of the box-like body with adjustment means integrated into the fixing plate and rear wall, allowing for flexible adjustment of handing and entry without additional components, maintaining a compact construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixing plate and counterplate are added to enable adjustment of handing and entry, then the lock achieves high flexibility of use, but the device complexity increases and compactness is penalized
Solution Approach 1:
The invention merges the adjustment means directly into the rear wall of the box-like body, eliminating the need for a separate fixing plate and counterplate. The rear wall itself becomes the adjustable component, integrating multiple functions into a single structure, thereby reducing device complexity while maintaining adaptability.
Solution Approach 2:
The rear wall is designed to perform multiple functions: it serves as both the mounting surface for the cylinder and the adjustable element for changing handing and entry. This multi-functionality eliminates the need for additional specialized components, reducing overall device complexity.
2Adaptability or versatility
If a fixing plate and counterplate are added to enable adjustment of handing and entry, then the lock achieves high flexibility of use, but the final cost of the product increases
Solution Approach 1:
By combining the adjustment functionality into the existing rear wall structure, the invention eliminates the need for additional parts that would require separate manufacturing and assembly processes. This reduction in part count directly lowers manufacturing costs while preserving the ability to adjust handing and entry.
3Adaptability or versatility
If a fixing plate and counterplate are added to enable adjustment of handing and entry, then the lock achieves high flexibility of use, but the compactness of the lock is reduced
Solution Approach 1:
The invention eliminates the need for a separate counterplate by integrating the adjustment mechanism into the rear wall itself. This merger removes the cumulative thickness of multiple components, maintaining a compact overall depth while preserving full adjustment capability for handing and entry.
