Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed calibration apparatus is used for each sensor, then calibration accuracy is maintained, but device complexity and space requirements increase
Solution Approach 1:
The patent implements a universal calibration apparatus that can calibrate multiple different sensors (radar, camera, ultrasonic sensors) through a single movable platform. The platform includes adjustable positioning mechanisms that allow it to be configured for different sensor types and calibration requirements, eliminating the need for multiple fixed calibration devices for each sensor type.
Solution Approach 2:
The calibration apparatus employs a movable platform with adjustable positioning mechanisms including screw rods for height adjustment and sliding mechanisms for horizontal positioning. These dynamic components allow the apparatus to adapt its position and orientation to match different sensor locations and calibration requirements, maintaining calibration accuracy while reducing device complexity.
2Measurement precision
If separate calibration apparatuses are used for different vehicle models, then calibration accuracy is maintained, but ease of operation and time efficiency decrease
Solution Approach 1:
The calibration apparatus is designed as a universal solution that can accommodate multiple vehicle models and sensor types. The movable platform with adjustable positioning mechanisms allows operators to configure the apparatus for different calibration scenarios without requiring model-specific equipment, significantly improving ease of operation and reducing calibration time across different vehicle models.
Solution Approach 2:
The calibration apparatus is divided into independent functional modules including the movable platform, positioning mechanisms, and calibration tools. This segmentation allows each component to be independently adjusted and configured for different vehicle models and sensor types, maintaining calibration accuracy while simplifying operation through modular adaptability.
3Adaptability or versatility
If multiple fixed calibration devices are deployed for different sensors, then calibration coverage is improved, but loss of time and operational efficiency increase
Solution Approach 1:
The movable calibration platform can calibrate multiple sensor types (radar, camera, ultrasonic sensors) within a single operational session. By consolidating multiple calibration functions into one apparatus, the system reduces the time required to perform sequential calibrations that would otherwise require multiple fixed devices, thereby reducing operational time loss while maintaining comprehensive calibration coverage.
Solution Approach 2:
The dynamic positioning capabilities of the movable platform enable rapid reconfiguration between different calibration tasks. The platform can be quickly repositioned and adjusted for different sensor locations and calibration requirements, minimizing the time required to transition between calibration operations while maintaining comprehensive coverage across all sensor types.
