Motor Vehicle Lock Control Drive Override Variants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing motor vehicle lock systems face challenges in efficiently implementing variant formations for the override function, which is cost-intensive due to the need for different components and complex production logistics.
Innovation Solution
The motor vehicle lock system allows for different mechanical locking states to be set with identical locking instructions but varying mechanical parameterizations, adjustable through control drive positions, enabling the implementation of single-pull and double-pull override functions purely through control technology, eliminating the need for multiple components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different components are provided for single-pull and double-pull override functions, then the functional requirements of different customers are met, but the production engineering effort and logistical costs increase
Solution Approach 1:
A single control drive unit is designed to perform multiple functions by adjusting its control position. The control drive can be positioned to enable either single-pull override function or double-pull override function, eliminating the need for separate components for each variant. This multi-functionality approach allows one component to serve multiple purposes based on configurable parameters.
Solution Approach 2:
The override function variant is determined by changing the control position parameter of the control drive rather than using different physical components. By adjusting the control position, the same control drive unit can implement different override functions (single-pull or double-pull), thus reducing production complexity and logistical requirements.
2Adaptability or versatility
If different components are provided for single-pull and double-pull override functions, then the functional requirements of different customers are met, but the logistical effort within production process increases
Solution Approach 1:
The control drive unit is designed as a universal component that can implement both single-pull and double-pull override functions. This eliminates the need for maintaining separate inventory streams for different override function components, thereby simplifying parts logistics and reducing device complexity in the production process.
Solution Approach 2:
The patent merges the functionality of separate single-pull and double-pull override components into a single control drive unit. By combining these functions into one component with adjustable control positions, the system reduces the number of unique parts that need to be managed in logistics.
3Ease of manufacture
If control positions of control drive are used to adjust mechanical parameterizations, then variant formation can be programmed electronically, but the control system complexity increases
Solution Approach 1:
The patent uses parameter changes in the control position of the control drive to achieve different mechanical parameterizations. This allows electronic programming of variant formation while keeping the control system relatively simple, as it only requires positioning adjustments rather than complex control logic.

AI summary
The invention relates to a motor vehicle lock with locking elements such as a latch (1) and a locking pawl (2), with a locking mechanism (4) and with an actuating lever (5, 6), wherein the locking mechanism (4) can be brought into different mechanical locking states and has a control drive (7) for this purpose, wherein each locking state is assigned a locking instruction, and wherein the locking instruction defines whether the motor vehicle lock can be opened by actuating the actuating lever (5, 6). It is proposed that at least one locking state can be set to different mechanical parameters with identical locking instructions, and that the different parameters of the locking state can be set by moving the control drive (7) to different control positions.
