Motor Vehicle Door Lock Inhibition Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle door locks lack a non-intrusive, integrated mechanism to protect against external mechanical and electrical attacks, particularly in heavy goods vehicles where driver safety and cargo security are concerns.
Innovation Solution
A motor vehicle door lock with a main mechanism and secondary mechanisms, featuring an inhibition mechanism that can be centrally activated and deactivated, preventing external access by rendering user interfaces ineffective, and is designed to be scalable and coexist with existing lock functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional independent interfaces are added to protect against external attacks, then security is improved, but device complexity and intrusiveness increase
Solution Approach 1:
The patent merges the inhibition function with the existing lock mechanism by integrating the inhibition mechanism into the lock body. The activation and deactivation means are incorporated into the lock structure, allowing the inhibition function to be exercised without requiring separate independent interfaces. This integration reduces device complexity while maintaining security functionality.
Solution Approach 2:
The lock mechanism is designed to perform multiple functions: normal locking/unlocking operation and inhibition function. The same lock mechanism can both control the bolt and provide inhibition when activated, making the system multi-functional and reducing the need for separate dedicated interfaces for each function.
2Reliability
If additional independent interfaces are added to protect against external attacks, then security is improved, but the lock becomes more intrusive in the cabin environment
Solution Approach 1:
The inhibition function is merged into the existing lock structure, eliminating the need for separate independent interfaces that would be intrusive in the cabin environment. The activation and deactivation means are integrated into the lock body, allowing the function to be exercised without adding additional components that would interfere with the cabin space or operation.
3Ease of operation
If a centralized control mechanism is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The centralized control is achieved by merging the inhibition function with the existing lock mechanism. The activation and deactivation means are integrated into the lock body, allowing a single centralized control point that manages both the normal locking operation and the inhibition function, thereby improving ease of operation without requiring separate control systems.
Solution Approach 2:
The lock mechanism serves as a universal control point for both normal locking/unlocking and inhibition functions. This multi-functionality allows centralized control without requiring additional separate control mechanisms, as the same lock structure handles all control operations.
