Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device is provided for the battery unit without authentication requirements, then the replacement process is simple and fast, but the security against theft is insufficient
Solution Approach 1:
The system implements bidirectional communication between the ID transmitter and the motor vehicle, where the control unit receives identification data from the ID transmitter, processes authentication, and sends control signals back to change the locking state. This feedback mechanism ensures secure authentication while maintaining operational simplicity for authorized users.
Solution Approach 2:
The patent replaces traditional mechanical key-based locking systems with an electronic authentication system using ID transmitters and control units. This substitution provides enhanced security through electronic verification while maintaining ease of operation through contactless or minimal-contact authentication methods.
2Reliability
If an ID transmitter with bidirectional communication is implemented, then authentication security is improved, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it receives and processes identification data from the ID transmitter, performs authentication verification, and controls the locking device state changes. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while maintaining high authentication security.
Solution Approach 2:
The patent combines the authentication processing and locking control functions within a single control unit integrated into the motor vehicle's existing electronics. This merging of functions reduces the number of separate components and simplifies the overall system architecture while maintaining robust authentication security.
3Reliability
If authentication queries are carried out via wake-up signals and identification data checks, then unauthorized access is prevented, but the operation time and complexity increase
Solution Approach 1:
The system performs preliminary authentication checks by first sending a wake-up signal to activate the ID transmitter, then immediately verifying identification data. This preliminary action ensures that authentication security is maintained while the process is optimized to minimize time loss through efficient signal processing and verification sequences.
