Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manufacturer-specific calibration stands and target frames are used for different vehicle manufacturers and models, then calibration accuracy for each specific vehicle is improved, but device complexity and the number of required calibration systems increase
Solution Approach 1:
The patent applies universality by designing a single calibration stand with interchangeable target frames that can accommodate multiple vehicle manufacturers and models. The stand structure remains universal while the target frames are selectively changed based on the specific calibration requirements, allowing one stand to perform multiple calibration functions across different vehicle types without requiring separate dedicated stands for each manufacturer.
Solution Approach 2:
The patent segments the calibration system into a universal stand structure and separate interchangeable target frames. This segmentation allows the stand to remain a permanent, robust infrastructure while only the target frames need to be changed for different vehicle types, reducing the overall complexity compared to having completely separate calibration systems for each manufacturer.
2Reliability
If multiple dedicated calibration stands are maintained for different vehicle manufacturers, then calibration reliability for each manufacturer is improved, but loss of time for setup and configuration increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple target frames with manufacturer-specific and model-specific calibration patterns before actual calibration work begins. These pre-prepared target frames are stored and readily available for quick attachment to the universal stand, eliminating the need for time-consuming on-site configuration and setup during calibration operations.
3Adaptability or versatility
If a universal stand with interchangeable components is used, then ease of operation and versatility are improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by making the target frames removable and interchangeable on the universal stand. This dynamic configuration allows the system to adapt its structure based on the specific calibration needs of different vehicle manufacturers and models, providing versatility while keeping the stand itself a relatively simple, permanent infrastructure that doesn't require complex reconfiguration.
