Motor Vehicle Lock Actuating Element Worm Contour
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing motor vehicle lock mechanisms require manual adjustment of the control shaft for various functional states, but the current design limits the pivoting range due to the implementation of an override function, making comprehensive manual adjustment difficult.
Innovation Solution
A longitudinally guided actuating element interacts with the control shaft's worm contour to enable full pivoting range adjustment, allowing for a worm gear-like mechanism that translates longitudinal movement into rotary motion, with a screw contour design providing a tailored gear ratio for comfort and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a control shaft with worm contour is used for manual adjustment, then the override function is implemented, but the pivoting range is limited
Solution Approach 1:
The actuating element is divided into two functional sections: a first section with a worm contour for engaging the control shaft's worm contour to enable manual pivoting, and a second section that interacts with the bending functional element to enable longitudinal adjustment. This segmentation allows the system to achieve both limited pivoting (for override function) and comprehensive longitudinal adjustment (for full functional range), resolving the contradiction between reliability and ease of operation.
2Ease of operation
If the actuating element is guided longitudinally to enable full pivoting range, then comprehensive manual adjustment is achieved, but the device complexity increases
Solution Approach 1:
The actuating element is designed as a multi-functional component that combines both pivoting engagement (via worm contour) and longitudinal adjustment capabilities within a single element. By guiding this universal element longitudinally in the direction of the control shaft's geometric axis, the system achieves comprehensive manual adjustment without requiring separate mechanisms for pivoting and positioning, thereby minimizing device complexity while maximizing operational flexibility.
