Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operators manually login to processing machines and export process data, then data can be obtained, but the process is time-consuming and inefficient
Solution Approach 1:
The system performs preliminary actions by pre-configuring wireless fields with interrogators and positioning identification tags on mobile devices before operators need data. When operators approach processing machines, the system automatically detects their location and pushes relevant process data without requiring manual login or data export operations, thus eliminating time loss.
Solution Approach 2:
The system enables self-service by automatically detecting operator positions through wireless fields and autonomously pushing relevant process data to their mobile devices. This eliminates the need for operators to manually login to machines or export data themselves, significantly improving data acquisition efficiency.
2Ease of operation
If operators manually login and export process data, then data can be accessed, but it is hard to visualize the process data immediately
Solution Approach 1:
The system introduces mobile devices as intermediaries between operators and processing machines. Instead of operators directly accessing machines through manual login, the mobile device receives pushed data from the server and displays visualized process information, making data visualization more accessible and immediate.
Solution Approach 2:
The system replaces the mechanical manual login process with wireless field-based automatic detection and data pushing. This substitution eliminates the need for physical login operations and automatically delivers visualized data to operators' mobile devices, significantly improving ease of operation and reducing time loss.
3Productivity
If the system provides automatic location sensing and real-time data pushing, then operational efficiency is enhanced, but device complexity increases
Solution Approach 1:
The system achieves multi-functionality by using a single wireless field-based identification system to simultaneously accomplish location detection, operator identification, and automatic data pushing. This universal approach enhances operational efficiency while avoiding the need for multiple separate complex systems.
