Engineering Contradictions & Design Principles
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 densely populated areas
Solution Approach 1:
The patent implements dynamic power adjustment of the laser sensor based on real-time vehicle speed and position data. The controller continuously modifies the radiated power level according to current operating conditions, transitioning from static constant-power operation to dynamic adaptive power control, thereby optimizing both detection capability and power consumption efficiency
Solution Approach 2:
The system changes the power parameter of the laser signal dynamically based on vehicle speed and position inputs. By adjusting the radiated power level according to environmental context (highway vs. urban areas), the system adapts its operational parameters to match detection requirements while minimizing unnecessary energy consumption and interference
2Length of stationary object
If the sensor operates at constant power, then the detection range is sufficient, but the interference with other systems increases in densely populated areas
Solution Approach 1:
The patent applies local quality adjustment by modifying the laser power level according to the specific operational context (vehicle speed and position). In urban environments with lower speeds and higher interference risk, the power is reduced locally, while on highways with higher speeds, the power is increased to maintain appropriate detection ranges for each specific operating condition
Solution Approach 2:
The system incorporates feedback mechanisms by continuously monitoring vehicle speed and position data, then using this information to adjust the laser power output. This closed-loop control ensures that the detection range remains sufficient while dynamically minimizing interference with other systems based on real-time environmental conditions
3Length of stationary object
If the radiated power is increased, then the detection range is extended, but the processing demands and interference increase
Solution Approach 1:
The patent implements partial action by adjusting the laser power to the minimum necessary level for each specific operating condition rather than always operating at maximum power. This approach extends detection range only when and where needed, reducing unnecessary processing demands and interference in situations where full detection capability is not required

AI summary
Methods and apparatus for providing dynamically adjusted radiated signals are disclosed. In one aspect, a method of detecting one or more objects in a path of travel of a vehicle may include generating a laser with radiated power. The method may further include emitting the laser in a direction of travel of the vehicle and receiving one or more reflections of the emitted laser reflected from the one or more objects located in the direction of travel of the vehicle. The method may also further include generating a signal indicating that the one or more objects are in a path of the vehicle based on the received one or more reflections. The method may also include dynamically adjusting the radiated power of the laser based on an input corresponding to one or more of (i) a current speed of the vehicle or (ii) a current position of the vehicle.
