Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single communication line is used to control target actuation, then the system complexity is reduced, but the reliability of actuation control deteriorates due to inability to properly manage actuation states
Solution Approach 1:
The communication system is segmented into two separate communication lines: a first communication line for transmitting actuation signals and a second communication line for transmitting status information. This segmentation allows independent optimization of each communication channel, improving overall reliability while maintaining manageable system complexity through modular design.
Solution Approach 2:
A control device acts as an intermediary between the communication lines and the target actuator. It receives signals from the first communication line, verifies status information from the second communication line, and then controls target actuation based on this processed information, ensuring reliable actuation control through intermediate verification.
2Reliability
If communication verification is implemented before target actuation, then the actuation control reliability is improved, but the response time deteriorates due to additional verification steps
Solution Approach 1:
The system performs preliminary verification of communication status through the second communication line before initiating target actuation via the first communication line. This preliminary action ensures that communication channels are functional and targets are in the correct state before actuation commands are executed, preventing wasted actuation cycles.
Solution Approach 2:
The second communication line continuously monitors and transmits status information about the target and communication channel health. This continuous verification enables the control device to maintain readiness for immediate actuation while ensuring reliability, reducing the effective verification time needed at actuation moments.

AI summary
A vehicle control device acquires a first communication state of a first instruction line which is connected to a target utilized for controlling a vehicle and issues an instruction for power for the entire vehicle separately from a power supply line for supplying power to the target, acquires a second communication state of a second instruction line which is connected to the target and differs from the power supply line and the first instruction line, actuates the target when a first signal indicating the instruction for power in the first communication state has been input to the first instruction line or when the second communication state is normal, and does not actuate the target when the first signal indicating the instruction for power in the first communication state has not been input to the first instruction line and the second communication state is not normal.
