Engineering Contradiction Analysis
1Reliability
If the sensor operates at constant power, then the detection capability is maintained, but the power consumption is inefficient and interference increases in zones with different driving speeds
Solution Approach 1:
The patent applies dynamics by making the radiated signal power adjustable rather than fixed. The system dynamically changes the power level of the laser based on real-time driving conditions (speed and position), allowing the sensor to adapt its detection capability to match the actual operational requirements of different zones, thereby reducing unnecessary power consumption while maintaining adequate detection performance.
Solution Approach 2:
The system changes the power parameter of the radiated signal based on input from speedometers and GPS. By adjusting the power level according to varying driving conditions, the system optimizes the balance between detection capability and power consumption, ensuring sufficient detection range at high speeds while reducing power usage in low-speed zones.
2Length of stationary object
If the sensor operates at constant power, then the detection range is sufficient, but interference with other systems increases
Solution Approach 1:
The system dynamically adjusts the radiated signal power based on the vehicle's speed and position. In zones where other systems operate, the power is reduced to minimize interference, while in open zones the power is increased to maintain adequate detection range. This dynamic adjustment resolves the contradiction between maintaining detection range and reducing interference.
Solution Approach 2:
By changing the power parameter of the radiated signal according to environmental conditions and vehicle operating parameters, the system achieves adaptive detection range that is sufficient when needed but reduced when it would cause interference to other systems.
3Length of stationary object
If the radiated power is increased, then the detection range is extended, but the power consumption increases
Solution Approach 1:
The system changes the power parameter dynamically based on actual detection needs determined by speed and position inputs. Instead of operating at maximum power continuously, the system adjusts the power level to provide sufficient detection range for current conditions, thereby extending detection capability when necessary while reducing power consumption when full range is not required.
