Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manufacturer-specific calibration stands and target frames are used for different vehicle manufacturers and models, then calibration can be performed for each specific vehicle type, but the device complexity and setup requirements increase significantly
Solution Approach 1:
The patent implements a universal calibration stand with a central support structure that can accommodate multiple target plates with different configurations. The stand is designed to work with various vehicle manufacturers and models through a standardized interface system, eliminating the need for manufacturer-specific calibration equipment while maintaining compatibility with different camera systems and calibration requirements
Solution Approach 2:
The calibration system is divided into modular components: a central support structure and multiple interchangeable target plates. Each target plate can be selectively attached to the central support depending on the specific calibration requirements. This segmentation allows a single stand to perform multiple calibration functions that previously required separate dedicated equipment for each vehicle type
2Measurement precision
If multiple different target configurations are used for different vehicles, then accurate calibration can be achieved for each vehicle type, but the quantity of calibration equipment and setup time increase
Solution Approach 1:
The patent employs a nested structure where multiple target plates with different configurations are attached to a central support structure. The target plates can be selectively positioned and configured based on the specific calibration needs, allowing one calibration stand to contain multiple target configurations that would otherwise require separate equipment
3Measurement precision
If manufacturer-specific calibration systems are used, then calibration can be performed for each vehicle model, but the ease of operation and setup simplicity decrease
Solution Approach 1:
The calibration system incorporates dynamic adjustability through the central support structure that can accommodate different target plates in various positions and orientations. The system transitions from static, manufacturer-specific configurations to a dynamic, adaptable setup where the calibration configuration can be changed by simply replacing target plates, making the system easier to operate across different vehicle types
