Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual hazard analysis is performed by inspector, then expertise and judgment can be applied, but the process is time-consuming and inefficient
Solution Approach 1:
The patent replaces the manual mechanical inspection process with an automated computer-based simulation system. Particles are simulated to scatter across the machine model surface, and their spin changes are automatically analyzed to detect hazard points, eliminating the need for manual inspector analysis and significantly improving certification efficiency
Solution Approach 2:
The patent creates a virtual copy or digital model of the machine to be inspected. This virtual model allows repeated simulation and analysis without requiring physical access to the actual machine, enabling efficient hazard detection during the design phase and reducing time loss during physical inspections
2Reliability
If comprehensive hazard analysis is performed, then safety is improved, but the complexity of the inspection process increases
Solution Approach 1:
The patent transforms the hazard detection problem into a measurable physical parameter analysis by tracking particle spin changes. This parameter-based approach provides objective, quantifiable criteria for hazard identification, improving detection reliability while maintaining manageable system complexity through clear measurement standards
Solution Approach 2:
The patent introduces particles as intermediary objects that interact with the machine model surface. These particles serve as mediators that translate complex surface geometry and hazard characteristics into measurable spin change data, simplifying the overall detection system while improving comprehensive hazard analysis capability
3Loss of time
If early-stage analysis is performed on virtual models, then time is saved, but measurement precision may be reduced compared to physical inspection
Solution Approach 1:
The patent performs hazard analysis on virtual models during the early design stage before physical prototypes are built. This preliminary action identifies potential hazards that can be corrected in the design phase, saving significant time while maintaining high measurement precision through accurate virtual model representation and rigorous particle simulation physics
