Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple environmental sensors are used to detect the vehicle's surroundings, then the coverage and detection capability are improved, but interference between sensors occurs leading to reduced signal quality
Solution Approach 1:
The system continuously monitors the quality of environmental data received from multiple sensors and provides feedback signals to control the operation of individual sensors. When interference is detected, the system feeds back control signals to switch off specific sensors, thereby maintaining optimal detection quality throughout operation.
Solution Approach 2:
The sensor configuration is made dynamic rather than static. The system can adaptively switch individual sensors on or off based on real-time interference conditions, allowing the sensor network to dynamically reconfigure itself for optimal performance in varying operational scenarios.
2Reliability
If environmental sensors operate continuously to maintain detection coverage, then the monitoring capability is improved, but energy consumption increases and interference occurs
Solution Approach 1:
Instead of continuous operation, sensors are activated periodically or intermittently based on detected interference conditions and trajectory overlap. The system switches sensors on only when needed for reliable detection, thereby reducing overall energy consumption while maintaining monitoring reliability.
Solution Approach 2:
The sensor operation schedule is dynamically adjusted based on real-time conditions. The system transitions from static continuous operation to dynamic selective operation, activating specific sensors only when their detection contribution is necessary and interference is absent.
3Measurement precision
If sensors are switched off to reduce interference, then signal quality is improved, but detection coverage may be reduced
Solution Approach 1:
The sensor network is segmented into independent controllable units. Individual sensors can be selectively switched on or off based on their specific spatial location and interference conditions, allowing the system to maintain coverage through remaining active sensors while eliminating interference from problematic ones.
Solution Approach 2:
A central control system acts as an intermediary between multiple sensors and the detection function. This mediator receives data from all sensors, evaluates interference conditions, and makes intelligent decisions about which sensors to activate, thereby optimizing both signal quality and coverage through coordinated control.
