Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual operation of the driving settings device is used, then the driver has direct control, but implementation of target driving behavior is delayed
Solution Approach 1:
The driving settings device is equipped with an actuator that automatically adjusts the device based on target driving behavior profiles stored in memory, eliminating the need for manual driver intervention and reducing response time while maintaining operational simplicity
Solution Approach 2:
The system continuously monitors the position of the driving settings device and automatically adjusts it to match the target driving behavior profile, creating a closed-loop feedback mechanism that eliminates delays in implementing desired driving behavior
2Loss of time
If autonomous control is implemented, then manual delays are avoided, but approval requirements and technical effort increase
Solution Approach 1:
Instead of implementing full autonomous control, the system uses a partial automation approach where the actuator automatically adjusts the driving settings device based on pre-stored target profiles, achieving the desired response time improvement while avoiding the complexity and approval requirements of complete autonomous control systems
Solution Approach 2:
Target driving behavior profiles are pre-stored in the memory device, allowing the actuator to automatically execute predetermined control actions without requiring real-time autonomous decision-making, thus reducing system complexity while maintaining timely response
3Manufacturing precision
If actuator operation is added to the driving settings device, then precise implementation of target driving behavior is achieved, but device complexity increases
Solution Approach 1:
The actuator is integrated into the driving settings device to automatically execute precise positioning based on target driving behavior profiles, achieving accurate control without requiring complex external systems or multiple separate devices
Solution Approach 2:
The actuator is combined with the existing driving settings device structure, merging the manual control mechanism with automatic actuation capability in a single integrated unit, thereby achieving precise control while minimizing additional complexity
