Motor Vehicle Lock Housing With Modular Media-Tight Electronics Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle lock housing arrangements lack flexibility in design to accommodate different functions and installation locations, limiting their adaptability and media-tightness.
Innovation Solution
A modular coupling of the carrier housing and electronics carrier with a seal interposed, forming a pre-assembled structural unit that can be easily adapted to various functions and locations while maintaining a media-tight connection with the lock housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plastic injection-molding connection is used to couple the carrier housing and lock housing, then a media-tight connection is achieved, but the design flexibility is limited
Solution Approach 1:
The housing arrangement is divided into separate lock housing and carrier housing components that can be independently designed and manufactured. The lock housing contains the locking mechanism while the carrier housing holds the electronics carrier, allowing each module to be optimized separately while maintaining media-tight connections through standardized coupling interfaces
Solution Approach 2:
The coupling interface between the lock housing and carrier housing is designed as a universal connection system that can accommodate different electronics carriers and locking mechanism configurations. This standardized interface enables the same basic housing structure to be adapted for various functions and installation locations without requiring complete redesign
2Device complexity
If the electronics carrier is integrated directly into the lock housing, then the structure is simplified, but adaptation to different functions and installation locations becomes difficult
Solution Approach 1:
The electronics carrier is separated from the lock housing and placed in its own carrier housing module. This segmentation allows the electronics carrier to be independently designed, removed, or replaced without affecting the locking mechanism, while the standardized coupling interface maintains overall structural simplicity
Solution Approach 2:
The coupling interface between the carrier housing and lock housing is designed to be dynamically adaptable, allowing the electronics carrier module to be easily attached or detached. This dynamic connection system enables quick reconfiguration for different functions and installation locations without complex assembly or disassembly procedures
