Motor Vehicle Lock Control Assembly for Coordinated Closing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle lock systems face challenges in harmoniously coordinating the closing processes of multiple locks, particularly in larger closure elements like side sliding doors or tailgates, leading to wear and inefficiencies due to varying mechanical conditions and soiling.
Innovation Solution
A control assembly that coordinates the closing processes of multiple vehicle locks through a common control specification, taking into account the positions and speeds of individual locks, ensuring simultaneous or sequential closing based on predefined criteria to enhance reliability and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple motor vehicle locks are equipped with independent closing assemblies, then each lock can close independently, but the closing processes cannot be coordinated harmoniously leading to wear and inefficiencies
Solution Approach 1:
The patent merges the control functions of multiple closing assemblies into a single control assembly that centrally coordinates the closing processes of all motor vehicle locks. This unified control approach enables harmonious coordination while maintaining reliable independent closing capability for each lock.
Solution Approach 2:
The control assembly receives sensor signals from position sensors associated with each motor vehicle lock and uses this feedback information to dynamically coordinate the closing processes. This feedback mechanism allows the system to adapt to varying mechanical conditions and ensure harmonious closing while maintaining reliability.
2Reliability
If closing processes are coordinated through a common control assembly, then harmonious and reliable closing is achieved, but the device complexity increases
Solution Approach 1:
The control assembly is designed as a universal control unit that can manage multiple motor vehicle locks and their closing assemblies through a single device. This multi-functional approach achieves harmonious coordination without proportionally increasing complexity, as one control assembly serves multiple locks.
Solution Approach 2:
The control assembly acts as an intermediary between the sensor assembly and the closing assemblies, centralizing the coordination function. This intermediary role enables harmonious control while keeping the overall system architecture manageable and the complexity increase controlled.
3Use of energy by moving object
If closing processes are optimized based on position sensor values, then power consumption is reduced and performance is enhanced, but the measurement and control requirements increase
Solution Approach 1:
The system uses position sensors already integrated into the motor vehicle locks to provide the necessary measurement data for optimized closing control. This self-service approach reduces power consumption through optimized closing sequences without significantly increasing measurement requirements, as the sensors serve dual purposes.
