Vehicle Locking Part with Deactivatable Pre-Lock Contour
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle locks with multiple locking positions are costly and complex, lacking clear guidance on physical design and arrangement of locking components, necessitating a simpler and cost-effective solution.
Innovation Solution
A locking mechanism for motor vehicle locks is developed with a first and second locking contour, where the second contour is deactivated to create a simpler mechanism by deriving from a multi-position lock, allowing production of different locks with identical parts in the same line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-locking position locking mechanism is used, then the locking system provides enhanced security and multiple locking states, but the device complexity and production costs increase
Solution Approach 1:
The locking part is designed with multiple locking contours (first and second locking contours) that can engage with different locking parts to provide multiple locking positions. The same locking part structure serves both single-locking and multi-locking position requirements by simply activating or deactivating the second locking contour, making the mechanism universal for different security requirements without increasing complexity.
Solution Approach 2:
The second locking contour is designed to be dynamically activatable or deactivatable. By making the second locking contour inaccessible to another locking part (deactivated), the system can adapt between providing one or two locking positions based on requirements, allowing the mechanism to change its functional state without physical modification.
2Adaptability or versatility
If a multi-locking position locking mechanism is designed, then the system can accommodate different locking requirements, but development costs and production complexity increase
Solution Approach 1:
The same locking part design with multiple contours serves different locking requirements (single or multi-position) without requiring separate development or production lines. By deactivating the second locking contour when not needed, the system achieves versatility while maintaining cost-effective production through identical parts for both lock types.
Solution Approach 2:
The system changes the operational parameter of the second locking contour from accessible to inaccessible (activated to deactivated) to adapt between different locking position requirements. This parameter change allows the same physical structure to provide different functional outcomes without increasing production complexity or cost.
3Reliability
If a second locking contour is added to provide pre-locking position, then the locking system offers additional security states, but the manufacturing complexity and cost increase
Solution Approach 1:
The locking part structure with the second locking contour serves dual purposes: it provides an additional pre-locking position when activated, but the same structure can be used for simple single-position locking when the second contour is deactivated. This universality eliminates the need for separate manufacturing processes for different locking configurations.
Solution Approach 2:
The second locking contour is designed with dynamic accessibility - it can be made accessible or inaccessible based on requirements. This dynamic design allows the system to provide enhanced security with an additional locking state only when needed, while maintaining simple manufacturing for applications requiring only a single locking position.

AI summary
The invention relates to a locking element for a locking mechanism (4) of a motor vehicle lock (2), in particular a latch (6), with a first locking contour (7) for locking the motor vehicle lock (2) in a first locked state, in particular the main locked state. It is proposed that the locking element (5) has a second locking contour (8) for locking the motor vehicle lock (2) in a further locked state, in particular a pre-locking state, which is deactivated, such that the deactivation prevents the second locking contour (8) from being accessible for locking by another locking element (5).
