Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the ultrasonic sensor range is restricted and the updating period is increased during parking control, then power consumption is reduced, but the vehicle speed is restricted and the total parking time is significantly increased
Solution Approach 1:
The system dynamically adjusts the sensor updating period based on the vehicle's operational state. During active parking control when the vehicle is moving, the sensor updates frequently to ensure safety. When the vehicle is stationary or parking is complete, the updating period is extended or sensing is stopped, reducing power consumption while maintaining parking time efficiency.
Solution Approach 2:
The patent changes the temporal parameter (updating period) of the sensor based on operational conditions. By varying the sensing frequency according to whether the vehicle is in motion or stationary, the system optimizes the balance between power consumption and parking execution time.
2Loss of energy
If the ultrasonic sensor range is restricted and updating period is increased, then sensor power consumption is reduced, but the vehicle speed control accuracy deteriorates leading to potential collisions
Solution Approach 1:
The system implements dynamic sensor activation based on vehicle motion state. When the vehicle is moving during parking control, ultrasonic sensors are activated with normal updating periods to maintain collision avoidance reliability. When the vehicle is stationary, sensor activation is reduced or stopped, lowering power consumption without compromising safety.
Solution Approach 2:
The patent dynamically changes the operational parameters of the sensor system, specifically the updating period and activation state, based on real-time vehicle conditions. This ensures that sensing accuracy is maintained during critical motion phases while power consumption is minimized during stationary phases.
3Measurement precision
If all sensors are activated continuously for accurate parking control, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The system dynamically controls sensor activation based on the parking control state. During active parking execution when the vehicle is moving, all necessary sensors are activated to ensure accurate detection of parking spaces and obstacles. When the vehicle is stationary or parking is complete, sensor activation is reduced or stopped, minimizing power consumption while maintaining detection accuracy during critical operations.
Solution Approach 2:
The patent changes the operational parameters of the sensor system, specifically the activation state and updating period, based on real-time vehicle conditions. This dynamic parameter adjustment ensures that measurement precision is maintained during active parking control while power consumption is optimized during stationary phases.
