Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fire-fighting gas intake and discharge device is installed to discharge combustible gas, then safety against explosions is improved, but the system becomes open-looped and cannot monitor operational faults, worsening reliability
Solution Approach 1:
The patent introduces feedback mechanisms through operation detection modules that continuously monitor the fan and louver states. The control board receives real-time feedback signals from these modules to determine whether components are operating normally. When abnormality is detected, the system automatically performs protective actions, transforming the open-loop system into a closed-loop control system that enhances reliability while maintaining safety functionality.
2Device complexity
If the system operates without real-time monitoring, then device complexity is reduced, but environmental information cannot be recorded, worsening maintenance efficiency
Solution Approach 1:
The operation detection modules enable the system to self-monitor and self-diagnose operational faults. The control board automatically detects abnormal states of the fan and louver without requiring external monitoring equipment or manual inspection. This self-service capability records environmental information and operational status, facilitating efficient maintenance while keeping the overall device complexity manageable through integrated detection functions.
3Ease of manufacture
If simple control components are used without detection modules, then manufacturing cost is reduced, but the system lacks robustness and cannot perform protective actions, worsening safety
Solution Approach 1:
The patent implements preliminary protective actions by equipping the control board with detection capabilities that identify potential faults before they lead to system failure. The operation detection modules continuously assess the operational status of critical components, and when abnormalities are detected, the control board automatically initiates protective measures. This preliminary action approach enhances system robustness and safety while maintaining manufacturing feasibility through cost-effective detection and control components.
