Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operation of mining machines is stopped to secure safety, then safety of workers is improved, but productivity at the mine is reduced
Solution Approach 1:
The system performs preliminary actions by pre-defining prohibited areas and pre-establishing communication protocols before conflicts occur. The management system proactively sets up virtual fences around equipment locations and pre-configures alert mechanisms, so that when mining machines approach these areas, immediate preventive actions can be taken without stopping operations abruptly.
Solution Approach 2:
The management system acts as an intermediary between mining machines and other equipment. It receives position information from GPS detectors on mining machines, compares it with prohibited area data, and mediates by sending alert signals to prevent entry into restricted zones. This intermediary function allows continuous operation while maintaining safety through automated coordination.
2Reliability
If the operation of mining machine is stopped when other equipment operates at the mine, then safety is improved, but productivity is reduced
Solution Approach 1:
The system enables self-service by allowing each piece of equipment to autonomously monitor its own position via GPS detectors and automatically receive alerts when approaching prohibited areas. The management system provides self-monitoring and self-protection capabilities, eliminating the need to stop operations for manual safety checks and enabling continuous productive work.
Solution Approach 2:
The system implements continuous feedback loops where position information from GPS detectors is constantly fed back to the management system, which then provides real-time feedback signals to operators when mining machines approach prohibited areas. This closed-loop feedback mechanism allows dynamic safety management without interrupting ongoing operations.
3Productivity
If GPS detection is used to set prohibited areas, then operational efficiency is improved, but system complexity increases
Solution Approach 1:
The management system achieves multi-functionality by using GPS detectors for multiple purposes: tracking mining machine positions, defining prohibited areas, generating alerts, and coordinating with other equipment. This universal use of GPS technology eliminates the need for separate specialized systems, reducing overall system complexity while maintaining high operational efficiency.
