Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous driving-based parking is implemented using UWB ranging technology, then parking convenience and automation are improved, but user manipulation and control complexity increase
Solution Approach 1:
The system enables the electronic device to perform autonomous parking operations by itself. The controller automatically determines the target location based on UWB ranging measurements and executes the parking maneuver without requiring continuous user input or manual control, allowing the device to serve itself in the parking task.
Solution Approach 2:
The system performs preliminary actions by first measuring the distance to the target location using UWB ranging technology before executing the autonomous parking maneuver. This preliminary measurement and planning phase allows the system to prepare the parking trajectory and parameters in advance, reducing the complexity of real-time control during actual parking execution.
2Manufacturing precision
If UWB ranging is used to determine target location for autonomous parking, then parking precision is improved, but communication and system requirements increase
Solution Approach 1:
The system replaces traditional mechanical or manual positioning methods with UWB (Ultra-Wideband) ranging technology for distance measurement. This substitution enables precise determination of the target location through wireless communication signals, achieving high parking precision without requiring complex mechanical positioning systems or additional physical sensors.
