Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed safety systems are installed in underground work sites, then safety monitoring coverage is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent transforms fixed safety systems into mobile passage control units that can be dynamically repositioned. The mobile unit includes sensors, processors, and communication devices that enable it to move freely while maintaining safety monitoring functions, thus reducing installation complexity while preserving safety coverage
Solution Approach 2:
The patent replaces mechanical fixed installations with wireless communication systems. The mobile passage control unit uses wireless communication devices to communicate with remote locations, eliminating the need for complex physical wiring and mounting infrastructure while maintaining system reliability
2Reliability
If fixed passage control units are used, then area isolation reliability is improved, but adaptability to changing environments deteriorates
Solution Approach 1:
The mobile passage control unit can be physically moved to different locations within the underground work site. This dynamic positioning capability allows the system to adapt to changing environmental conditions and work areas while maintaining reliable area isolation through continuous safety monitoring and access control functions
3Measurement precision
If mobile passage control units with three-dimensional sensing are deployed, then positioning accuracy and safety monitoring are improved, but device complexity increases
Solution Approach 1:
The mobile passage control unit integrates multiple functions into a single device: three-dimensional sensing for positioning, safety monitoring, communication, and area isolation control. This multi-functionality reduces the need for separate specialized devices, thereby managing overall system complexity while achieving high positioning accuracy through the integrated sensing capabilities
