Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data collection is performed independently for numerical controller and peripheral equipment, then data collection capability is provided, but operational complexity increases and data analysis efficiency deteriorates
Solution Approach 1:
The patent combines the data collection functions of the numerical controller and peripheral equipment into a single integrated system. The numerical controller serves as a centralized data collection hub that automatically gathers both numerical control data and peripheral equipment data, eliminating the need for separate independent control operations and reducing overall system complexity.
Solution Approach 2:
The numerical controller is designed to perform multiple functions: it not only controls the machining process but also universally collects data from both the numerical control system and various peripheral equipment. This multi-functionality allows a single device to handle diverse data collection tasks without requiring specialized separate systems.
2Quantity of substance
If data from multiple equipment are collected with different time stamps and sampling cycles, then comprehensive process data is obtained, but data analysis difficulty increases
Solution Approach 1:
The system performs preliminary data processing by automatically synchronizing time stamps and adjusting sampling cycles during the data collection phase. The numerical controller pre-processes the collected data to establish a unified time reference and consistent sampling interval, so that when the data reaches the analysis stage, it is already organized and comparable without requiring additional manual adjustment.
3Extent of automation
If external data loggers and applications are used for automated data collection, then data collection automation is achieved, but system cost increases
Solution Approach 1:
The numerical controller is equipped with built-in automated data collection and processing capabilities, allowing the system to serve itself without requiring external data loggers or separate application software. The controller automatically manages data acquisition, time synchronization, and aggregation, eliminating the need for additional expensive external devices and reducing overall system cost.
