Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a park assist system automatically steers the vehicle during parallel parking, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The park assist system enables the vehicle to perform parallel parking autonomously by automatically controlling steering based on sensor data and computed trajectories, allowing the system to serve itself without requiring manual driver intervention for steering operations
Solution Approach 2:
The system replaces manual mechanical steering control with an automated control system that uses sensors to detect parking spaces and computes steering trajectories, substituting human-operated mechanical steering with an automated electromechanical system
2Productivity
If the park assist system allows minimal driver action, then the productivity is improved, but the reliability may worsen due to reduced driver control
Solution Approach 1:
The system continuously monitors the parking maneuver using sensors that detect the vehicle's position relative to the parking space and surrounding objects, providing real-time feedback to the control system to adjust steering and ensure safe execution of the parking operation
Solution Approach 2:
The system performs preliminary detection of suitable parking spaces and computation of steering trajectories before executing the parking maneuver, preparing the automated steering system in advance to ensure safe and efficient parking execution
