Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calibration methods are used, then device complexity is reduced, but measurement precision and calibration accuracy deteriorate due to human error and inability to address vehicle variations
Solution Approach 1:
The calibration apparatus performs self-calibration by automatically moving to predetermined positions, acquiring calibration signals from the vehicle, and computing calibration parameters without requiring manual intervention. The system serves itself by integrating positioning, signal acquisition, and parameter computation functions into an autonomous calibration process.
Solution Approach 2:
The calibration apparatus is designed as a multi-functional integrated system that combines positioning capabilities (GPS/北斗), signal acquisition (beacon signal reception), computation (calibration parameter calculation), and navigation (movement to target positions). This universal device can adapt to different vehicle types and calibration requirements.
2Productivity
If automated calibration apparatus is deployed, then productivity and calibration efficiency are improved, but device complexity increases due to multiple integrated components
Solution Approach 1:
The patent merges previously separate calibration operations into a single integrated apparatus that combines positioning modules, beacon signal acquisition modules, and computation modules. By combining these functions into one unified system, the apparatus achieves high productivity while managing complexity through integration rather than multiplication of separate devices.
Solution Approach 2:
The system replaces manual mechanical calibration operations with automated electronic and computational processes. The apparatus uses electronic positioning (GPS/北斗), electronic signal acquisition (beacon signals), and computational algorithms to perform calibration, substituting human-operated mechanical procedures with automated electromechanical systems.
3Measurement precision
If calibration is performed at multiple positions, then measurement precision is improved, but loss of time increases due to movement and positioning requirements
Solution Approach 1:
The calibration apparatus pre-calculates and stores predetermined positions for calibration before actual calibration begins. These positions are determined in advance based on vehicle characteristics and calibration requirements. By preparing the calibration path and positions beforehand, the system minimizes unnecessary movement time during actual calibration execution while ensuring measurement precision at all required positions.
