Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual alignment method is used, then driver can control vehicle positioning, but alignment accuracy decreases and driver effort increases
Solution Approach 1:
The alignment system uses sensors (cameras, GPS, proximity sensors) to detect the transmitter location and provides real-time feedback to the driver through the display interface, showing directional cues and distance information to guide precise alignment without requiring manual trial-and-error positioning
Solution Approach 2:
The system introduces an intermediary alignment assistance system that mediates between the driver's manual control and the alignment target, using sensors and display interfaces to bridge the information gap and enable accurate alignment with minimal driver effort
2Adaptability or versatility
If transmitter location is obscured, then wireless recharging can be performed, but alignment difficulty increases
Solution Approach 1:
The vehicle is equipped with multiple types of sensors (cameras, GPS, proximity sensors) that can detect transmitter location through various means, making the system adaptable to different environmental conditions and transmitter positions, including obscured locations
Solution Approach 2:
The alignment system acts as an intermediary that detects the transmitter's location using multiple sensor types and translates this information into driver-friendly guidance cues, enabling the driver to align the receiver even when the transmitter is not visually visible
3Productivity
If automated alignment system is implemented, then alignment speed increases, but system complexity increases
Solution Approach 1:
The controller receives real-time feedback from multiple sensors regarding the vehicle's position relative to the transmitter and automatically adjusts steering and propulsion commands to achieve rapid alignment, reducing alignment time while managing complexity through closed-loop control
Solution Approach 2:
The automated alignment system performs self-correction by continuously monitoring sensor data and autonomously adjusting vehicle position and orientation, enabling rapid alignment without requiring complex manual intervention from the driver
