Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 100% redundancy control mechanisms are implemented, then safety and reliability are improved, but system complexity and cost increase
Solution Approach 1:
The gas control system is divided into multiple independent redundant groups, each capable of operating autonomously. The system segments control functions across multiple valves and controllers, so that if one segment fails, others can maintain operation. This segmentation provides 100% redundancy while managing complexity through modular design.
Solution Approach 2:
The system performs preliminary actions by pre-configuring redundant control paths and monitoring mechanisms before failures occur. Controllers continuously monitor system state and prepare backup control sequences, ensuring that safety functions are already in place and can activate immediately upon detecting a failure condition.
2Reliability
If 100% redundancy control mechanisms are implemented, then safety and reliability are improved, but operational costs increase
Solution Approach 1:
The redundant control system operates dynamically, actively monitoring system parameters and switching between active and standby control paths based on real-time conditions. This dynamic operation ensures safety through redundancy while optimizing energy consumption by keeping backup systems in lower-power monitoring states rather than full operational states.
Solution Approach 2:
The redundant control system performs self-diagnosis and self-management, with controllers monitoring their own operational status and automatically switching to backup components when needed. This self-service capability reduces the need for external intervention and optimizes resource utilization, lowering operational costs while maintaining 100% safety redundancy.
3Quantity of substance
If high-pressure natural gas storage and distribution is implemented, then gas supply capability is improved, but safety risks increase
Solution Approach 1:
The system implements beforehand cushioning through multiple layers of safety valves and pressure control mechanisms that are pre-positioned to prevent or mitigate hazardous events. These protective measures are configured to activate before dangerous pressure levels can develop, cushioning against potential safety risks while maintaining high-pressure gas storage and distribution capability.
Solution Approach 2:
The control system introduces intermediary safety components, including pressure-regulating valves and monitoring devices, that mediate between the high-pressure gas storage and the distribution network. These intermediaries buffer and control pressure transitions, reducing safety risks associated with high-pressure operations while preserving gas supply capability.
