Moveable Drive Lock Module for Vehicle Door Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of motor vehicle side doors with more modules and components has led to increased assembly work for lock modules, due to growing space constraints and variety of door types, making installation more challenging.
Innovation Solution
A lock module with a moveable drive that is initially adjustable during assembly to facilitate installation, featuring a flange connection or snap-in elements, allowing the drive to be prepositioned for easier alignment and secured in specific positions to simplify the assembly process, utilizing a Bowden cable for remote operation and a web connection for flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of modules and components in motor vehicle side doors increases, then the functionality and comfort level improve, but the assembly work and installation complexity increase
Solution Approach 1:
The patent combines multiple components (lock mechanism, drive unit, actuating lever system, handle module) into a single integrated lock module assembly. This merging reduces the number of separate parts that need to be handled during assembly, thereby reducing assembly complexity while maintaining all necessary functionalities including locking, unlocking, and door opening operations
Solution Approach 2:
The lock module is designed as a universal assembly that can be installed in different motor vehicle door types. The module integrates multiple functions (locking, unlocking, handle operation) into a single standardized unit that can adapt to various door configurations, reducing the need for custom assemblies for each door type and thereby reducing overall assembly complexity
2Adaptability or versatility
If more modules and components are installed in motor vehicle side doors, then the space utilization improves, but the space constraints and assembly difficulty increase
Solution Approach 1:
The patent segments the lock system into a modular assembly comprising distinct functional units (lock mechanism, drive unit, handle module) that are pre-assembled together. This segmentation allows the entire lock system to be installed as a single module, reducing the number of separate installation steps and making assembly easier despite the presence of multiple components within the module
3Manufacturing precision
If the drive is fixed in position during installation, then the manufacturing precision improves, but the adaptability to different door types decreases
Solution Approach 1:
The drive unit is designed with moveable mounting capabilities, allowing its position to be adjusted during assembly. The drive can be positioned at different locations on the lock module depending on the specific door type and installation requirements. This dynamic positioning capability maintains manufacturing precision through controlled adjustment mechanisms while providing adaptability to different door configurations

AI summary
The invention relates to a lock module. The aim of the invention is to provide a lock module which can contribute to a reduction in the complexity of assembly. In order to achieve said aim, the lock module comprises a plurality of components, that is to say at least two components, which are selected from the following: a lock having a locking mechanism consisting of a pawl and a rotary latch, in particular a servolock; a drive, in particular an electric drive for the lock, particularly preferably for the servolock; an actuating lever system; a locking lever system; and a handle module having an opening handle, in particular an outer opening handle. The lock includes at least one drive which is movably mounted within the lock module. The drive can therefore be moved relative to the other one or more components of the lock module.
