Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If in-vehicle radar signal strength is increased to improve detection capability, then detection precision is improved, but interference from surrounding vehicles increases
Solution Approach 1:
The radar signal strength is dynamically adjusted based on real-time detection of surrounding vehicles and calculated interference levels. The system transitions from static signal strength to adaptive signal strength that changes with environmental conditions, resolving the contradiction between maintaining high detection precision and avoiding interference.
Solution Approach 2:
The system changes the parameter of radar signal strength based on detected environmental conditions. By monitoring surrounding vehicles and calculating interference probabilities, the system adjusts signal strength parameters to optimize both detection precision and interference reduction.
2Object-affected harmful factors
If radar signal strength is decreased to reduce interference, then harmful factors are reduced, but detection precision deteriorates
Solution Approach 1:
Instead of using a fixed low signal strength, the system dynamically adjusts signal strength based on real-time environmental assessment. When interference risk is low, higher signal strength is used for precise detection; when interference risk is high, signal strength is reduced. This dynamic approach resolves the contradiction between reducing interference and maintaining detection precision.
Solution Approach 2:
The system changes radar signal strength parameters adaptively based on detected surrounding vehicles and calculated interference probabilities. This parameter adjustment ensures detection precision is maintained when possible while reducing interference when necessary.
3Reliability
If radar signal strength is increased to improve safety detection, then reliability is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts radar signal strength based on real-time assessment of surrounding vehicles and interference conditions. Instead of continuously operating at high power for maximum reliability, the system uses higher power only when necessary (when surrounding vehicles are detected and interference risk exists), thereby maintaining safety detection reliability while reducing overall energy consumption.
Solution Approach 2:
The radar signal strength parameter is changed adaptively based on environmental conditions. The system monitors surrounding vehicles and adjusts power parameters to achieve necessary reliability only when interference conditions warrant it, optimizing the balance between reliability and energy consumption.
4Use of energy by moving object
If radar signal strength is decreased to save energy, then energy consumption is reduced, but reliability of safety detection deteriorates
Solution Approach 1:
The system dynamically adjusts signal strength based on real-time environmental assessment rather than using a fixed low-power mode. When surrounding vehicles are detected and interference risk is calculated to be high, the system increases signal strength to maintain detection reliability. This dynamic approach ensures energy is saved during low-risk periods while reliability is maintained when needed.
Solution Approach 2:
The radar signal strength parameter is adaptively changed based on detected surrounding vehicles and calculated interference probabilities. This ensures energy consumption is optimized while maintaining necessary detection reliability when environmental conditions require it.
