Vehicle Lock Auxiliary Module Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle locks require extensive redesign and increased complexity for emergency unlocking mechanisms, leading to higher costs and logistical challenges due to the integration of auxiliary drives and energy sources, which complicates assembly and storage.
Innovation Solution
A functionally independent auxiliary module with a separate auxiliary drive and energy source is mechanically connected to the motor vehicle lock, allowing for emergency unlocking independently of the main drive, utilizing a high-gear ratio mechanism and low-power electromotive components, and integrating a data interface for secure authentication with an electronic key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an auxiliary drive with auxiliary motor and auxiliary gear is integrated into the motor vehicle lock, then operational safety in emergency situations is improved, but device complexity and construction complication increase
Solution Approach 1:
The auxiliary drive is separated from the main lock mechanism and integrated into a distinct auxiliary module that can be mechanically connected to the lock. This segmentation allows the auxiliary emergency unlocking function to be added without fundamentally redesigning the entire lock system, thereby improving operational safety while limiting the increase in construction complexity to a modular addition rather than system-wide complexity.
2Reliability
If the auxiliary drive is integrated into the motor vehicle lock, then emergency unlocking capability is improved, but manufacturing costs and storage costs increase
Solution Approach 1:
By segmenting the auxiliary drive into a separate auxiliary module, the manufacturing process is simplified. The auxiliary module can be manufactured independently and then mechanically connected to the existing lock, avoiding the need to redesign and remanufacture the entire lock assembly. This modular approach reduces manufacturing costs and simplifies logistics and storage compared to integrating the auxiliary drive directly into a completely redesigned lock system.
3Adaptability or versatility
If the auxiliary drive is integrated into the motor vehicle lock, then emergency operation functionality is improved, but assembly complexity increases
Solution Approach 1:
The auxiliary drive is implemented as a separately manufacturable auxiliary module that is mechanically connected to the lock. This segmentation enables the auxiliary module to be assembled independently and then attached to the existing lock mechanism, significantly reducing overall assembly complexity compared to integrating the auxiliary drive directly into a monolithic lock design where all components would need to be assembled together as a single complex unit.
