Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual verification is performed on actual vehicles, then evaluation can be conducted with simple equipment, but work efficiency is lowered and evaluation accuracy is insufficient
Solution Approach 1:
The patent replaces manual mechanical verification operations with an automated robot arm system that performs precise positioning and touching operations on the display screen. The robot arm is controlled by a computer to automatically navigate through GUI elements, eliminating human labor while maintaining or improving measurement precision through consistent, programmable movements.
Solution Approach 2:
The patent introduces a computer as an intermediary between the evaluator and the actual vehicle. The computer processes image data from the display, determines touch positions, controls the robot arm movements, and automates the evaluation workflow, thereby improving both efficiency and accuracy without requiring direct human intervention.
2Productivity
If automated evaluation is implemented, then work efficiency and accuracy are improved, but device complexity increases
Solution Approach 1:
The patent designs the robot arm system to perform multiple functions: positioning, touching, and navigating the display screen. The same robot arm and control system are used for various evaluation tasks, making the complex system versatile and justifying the complexity through multi-functional capability that improves overall evaluation efficiency.
Solution Approach 2:
The system incorporates automatic image processing and position determination algorithms that enable the evaluation system to self-correct and self-navigate. The computer automatically processes captured images to determine precise touch positions without human intervention, reducing the operational complexity despite the increased device complexity.
3Measurement precision
If quantitative evaluation is performed, then evaluation accuracy is improved, but it requires complex automated systems
Solution Approach 1:
The patent replaces subjective manual evaluation with objective automated measurement systems. The robot arm executes precise, programmable movements to interact with the display, and the computer systematically records and analyzes evaluation data, transforming qualitative manual assessment into quantitative automated measurement that improves accuracy while managing complexity through standardization.
