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 implements a universal calibration stand with adjustable components that can accommodate multiple vehicle manufacturers and models through configurable target plate positions, orientations, and dimensions. The stand includes adjustable arms, rotatable target plates, and variable positioning mechanisms that allow a single system to perform calibration across different vehicle types, replacing the need for multiple manufacturer-specific calibration systems while maintaining calibration accuracy
2Adaptability or versatility
If a universal calibration stand with adjustable components is used to accommodate different vehicles, then adaptability across manufacturers is improved, but device complexity increases
Solution Approach 1:
The calibration stand is divided into modular segments including adjustable arms, detachable target plates, and independent positioning mechanisms. Each component can be independently adjusted or removed, allowing the system to be configured for different vehicle types without requiring complete redesign. This segmentation enables versatility while keeping individual components relatively simple
Solution Approach 2:
The stand incorporates dynamic adjustment capabilities where target plates can be rotated, positioned at different heights, and oriented at various angles. The adjustable arms can extend or retract to accommodate different vehicle dimensions. These dynamic features allow a single stand structure to adapt to multiple configurations without requiring multiple fixed structures
