Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If repeated tests are conducted to determine optimal transfer velocity and acceleration based on transfer object weight, then the accuracy of transfer parameters is improved, but the time required for setup increases
Solution Approach 1:
The patent replaces the mechanical trial-and-error testing method with a calculation-based system. An acceleration determination device uses sensors to detect the transfer object's weight and automatically calculates optimal acceleration and velocity parameters, eliminating the need for repeated physical tests while maintaining accuracy.
Solution Approach 2:
The system performs self-determination of transfer parameters by automatically measuring the transfer object's weight and computing the optimal acceleration and velocity values without requiring external testing or manual adjustment. The device serves itself by integrating the measurement and calculation functions into a single automated process.
2Adaptability or versatility
If manual testing and adjustment of transfer parameters is performed, then the adaptability to different transfer objects is improved, but the operational complexity increases
Solution Approach 1:
The patent automatically adjusts transfer parameters (acceleration, velocity) based on changes in the transfer object's weight. The system detects weight variations and dynamically computes new parameter values, enabling adaptability to different objects without requiring complex manual testing procedures for each case.
Solution Approach 2:
The patent replaces complex manual testing and adjustment procedures with an automated calculation system. The acceleration determination device uses sensors and computational algorithms to directly determine optimal parameters, simplifying the operational process while maintaining adaptability to different transfer objects.
