Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motor specification values are used to select amplifiers and common power supplies, then the selection process is simple, but amplifiers and common power supplies with excessive capacity are selected
Solution Approach 1:
The system performs preliminary analysis of the machining program to calculate actual motor output requirements before amplifier and common power supply selection. This allows the selection to be based on actual operational needs rather than conservative specification-based selection, preventing excessive capacity while maintaining selection simplicity.
Solution Approach 2:
The patent replaces the manual specification-based selection method with an automated computer-based calculation system that analyzes machining programs and calculates actual motor output requirements. This substitution enables precise, data-driven selection that avoids excessive capacity while maintaining ease of operation through automation.
2Measurement precision
If all operating conditions are manually input for amplifier selection, then accurate selection can be achieved, but the operation becomes complex especially in complicated operations
Solution Approach 1:
The system automatically extracts and analyzes operating conditions from the machining program without requiring manual input. The computer-based system performs self-service by reading the program, calculating motor output at each time step, determining maximum output, and using this to select appropriate amplifiers and common power supplies, thereby maintaining accuracy while eliminating operational complexity.
Solution Approach 2:
The patent replaces manual input of operating conditions with automated computer-based analysis of machining programs. The system substitutes human operators with software that automatically extracts operational parameters, calculates requirements, and performs selection, thereby maintaining measurement precision while dramatically reducing operation complexity.
