Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If control signals from local devices are accumulated and evaluated in real-time, then production efficiency and quality control are improved, but system complexity and data processing requirements increase
Solution Approach 1:
The system segments control signals by process type (e.g., heating, cooling, mixing) and accumulates them separately in the database. This segmentation allows for organized storage and targeted evaluation of specific process signals, improving productivity while managing system complexity through structured data organization.
Solution Approach 2:
The information collection device acts as an intermediary between local devices and the evaluation system. It accumulates control signals from multiple local devices, extracts relevant signal sets based on process types, and generates evaluation results. This intermediary role simplifies the overall system architecture by centralizing data collection and processing functions.
2Measurement precision
If detailed control signals are accumulated and extracted for evaluation, then measurement precision and quality assessment are improved, but data processing time and computational resources increase
Solution Approach 1:
The system extracts specific signal sets from accumulated control signals based on process types (e.g., heating processes, cooling processes). By extracting only the relevant signals needed for evaluation rather than processing all accumulated data, the system achieves high measurement precision for quality assessment while reducing unnecessary data processing time.
Solution Approach 2:
The evaluation is performed locally for each process type with specific extraction conditions. The system applies different evaluation criteria to different process types (e.g., temperature control for heating, pressure control for compression), achieving high precision quality assessment tailored to each local process while optimizing processing efficiency.
