Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle locking systems face reliability and security issues when the electrical actuator is no longer powered, particularly in emergency situations, as they require a continuous energy supply and lack autonomous operation.
Innovation Solution
An assembly comprising a carrier-mounted blocking device, control and communication device, energy store, actuator, and generator, where the generator can be manually driven to charge the energy store, enabling autonomous operation and secure unlocking via an external communication device, ensuring only authorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an electrical actuator is used to control the mechanical locking device, then the locking system can be controlled remotely and automatically, but the system becomes dependent on continuous energy supply and loses reliability when power is unavailable
Solution Approach 1:
The system performs preliminary action by storing electrical energy in advance during normal operation when the vehicle's central energy store is available. The energy store is charged beforehand so that when power failure occurs, the actuator can still operate the locking device without external power supply, thus resolving the reliability issue while maintaining automation capability.
2Reliability
If a manual emergency actuation system is added to provide backup power, then reliability improves, but the device complexity increases
Solution Approach 1:
The patent merges the emergency operation components (generator device with actuating means, energy store, and control unit) into an integrated assembly that is coupled to the existing door handle and locking system. This consolidation approach provides emergency operation capability while minimizing the increase in overall device complexity by sharing components and using modular integration.
3Reliability
If all locking system components are integrated into a single autonomous assembly, then access security and reliability improve, but the manufacturing and installation complexity increases
Solution Approach 1:
The locking system is segmented into a self-contained autonomous assembly that includes all necessary components (blocking device, control unit, energy store, actuator, and generator device), while maintaining modular architecture that allows for standardized manufacturing and simplified installation as a complete unit on the vehicle door or hatch.
