Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the e-corner system uses sensors to receive alarm according to distance after vehicle moves during mode switching, then space constraints for mode switching can be utilized, but the driver cannot directly see with own eyes that the steering mode has been changed
Solution Approach 1:
The system provides visual feedback through a display device that shows the current steering mode (e.g., parallel parking mode, angle parking mode) and real-time sensor data about space constraints. This feedback loop ensures the driver can see and confirm mode changes while the system autonomously utilizes space constraints for mode selection.
Solution Approach 2:
A display interface acts as an intermediary between the sensor system and the driver. The display translates sensor data and mode change information into visual representations that the driver can understand, bridging the gap between autonomous system operation and driver awareness.
2Ease of operation
If the vehicle rotates in place during angle change, then parking maneuver is achieved, but the vehicle should be adjusted only by brake after operation which causes line misalignment and requires readjustment
Solution Approach 1:
The system continuously monitors vehicle position and orientation during and after the rotation maneuver using sensors. Real-time feedback allows the system to detect line alignment status and provide guidance signals to the driver for precise brake adjustment, eliminating the need for trial-and-error readjustment.
Solution Approach 2:
The system calculates and provides preliminary guidance information to the driver before the rotation maneuver begins, including the expected final position and required brake adjustment. This preliminary action prepares the driver for the precise adjustment needed after operation, improving line alignment accuracy.
3Measurement precision
If the system provides comprehensive sensing and trajectory calculation for each steering mode, then accurate mode determination is achieved, but the system complexity increases
Solution Approach 1:
The system employs a universal processor that performs multiple functions: sensing data acquisition, space region area calculation, trajectory switching determination, and driver guidance generation. This multi-functional approach achieves precise measurement capabilities without proportionally increasing system complexity, as one component handles diverse tasks.
Solution Approach 2:
The patent combines sensing functions, calculation functions, and guidance functions into an integrated system architecture. By merging these previously separate functions into a unified processing framework, the system achieves comprehensive precision without the complexity overhead of multiple independent subsystems.
