Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radar sensors are installed at different installation positions in the motor vehicle, then the sensor coverage and detection capability are improved, but the performance consistency and reliability deteriorate due to varying installation conditions
Solution Approach 1:
The patent applies local quality by storing installation position-specific configuration parameters in the control unit, allowing each radar sensor to receive customized configuration data corresponding to its specific installation location. This enables optimal performance for each sensor despite variations in installation conditions, resolving the contradiction between broad sensor coverage and performance consistency.
2Reliability
If multiple software variants and configurations are implemented for different installation positions, then the performance optimization for each position is improved, but the device complexity and handling complexity increase
Solution Approach 1:
The patent implements universality by using a single base software version for all radar sensors and storing position-specific configuration parameters in the control unit. This universal approach allows one software variant to serve multiple installation positions, reducing complexity while maintaining optimized performance through parameter customization rather than creating separate software variants for each position.
Solution Approach 2:
The patent applies preliminary action by pre-storing installation position-specific configuration parameters in the control unit before sensor installation. This allows the correct configuration to be automatically retrieved and applied after installation, eliminating the need for complex manual configuration processes and reducing overall system complexity.
3Measurement precision
If radar sensors are configured with position-specific parameters during installation, then the detection accuracy is improved, but the installation time and complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-storing all installation position-specific configuration parameters in the control unit before the actual sensor installation. This eliminates the need for time-consuming configuration processes during installation, as the correct parameters are already prepared and can be automatically applied, thus maintaining high detection accuracy while reducing installation time.
Solution Approach 2:
The patent implements self-service by enabling the radar sensor to automatically retrieve and apply its specific configuration parameters from the control unit after installation. This automated configuration process eliminates manual configuration tasks, maintaining detection accuracy while significantly reducing installation time and complexity.
4Reliability
If different radar sensor variants are used for different installation positions, then the performance for each position is optimized, but the manufacturing cost and handling complexity increase
Solution Approach 1:
The patent implements universality by designing a single radar sensor hardware variant that can be used at all installation positions, with position-specific performance optimization achieved through software configuration parameters stored in the control unit. This approach eliminates the need to manufacture different sensor variants for different positions, reducing manufacturing cost while maintaining optimized performance through parameter customization.
