Self-Adjusting Door Lock Catch Assembly for Fast Vehicle Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door lock catch assemblies require manual adjustment by multiple workers to achieve optimal positioning, which is time-consuming and inconsistent, affecting the quality of door closure sound and increasing labor costs.
Innovation Solution
A self-adjusting vehicle door lock catch assembly with a floating adjustment piece and limit block that automatically adjusts the lock catch body's position relative to the vehicle door, allowing for precise alignment in multiple directions, using a fastener to secure the assembly to the vehicle sidewall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional door lock catch assembly with separate mounting steps is used, then the door lock catch can be installed, but the installation process is complex and time-consuming
Solution Approach 1:
The door lock catch assembly integrates the door lock catch, mounting bracket, and fastening components into a single pre-assembled unit. The mounting bracket is pre-attached to the door lock catch body during manufacturing, combining multiple components that would otherwise require separate installation steps into one integrated assembly that can be installed as a single unit.
Solution Approach 2:
The mounting bracket is pre-assembled and pre-positioned on the door lock catch body before delivery to the installation site. This preliminary assembly action is performed during manufacturing rather than during installation, reducing the complexity and time required for the actual mounting process by having components ready in their final positions.
2Manufacturing precision
If manual alignment and adjustment during installation is performed, then positioning accuracy can be achieved, but installation time increases
Solution Approach 1:
The precise positioning and alignment of the mounting bracket relative to the door lock catch body is performed during manufacturing rather than during installation. This preliminary precision work ensures accurate positioning is achieved without requiring time-consuming manual alignment and adjustment procedures at the installation site.
Solution Approach 2:
By integrating the mounting bracket and door lock catch as a pre-assembled unit with pre-established precise positioning, the system combines manufacturing precision into the assembly itself, eliminating the need for separate alignment operations during installation and thereby reducing installation time while maintaining positioning accuracy.
3Ease of operation
If multiple separate components are used for the door lock assembly, then functionality can be achieved, but the number of installation steps increases
Solution Approach 1:
The invention merges the door lock catch, mounting bracket, and associated fastening components into a single integrated assembly. This reduces the number of separate components that need to be handled and installed individually, simplifying the installation process while maintaining all necessary functional elements within the unified structure.
