Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional stato-mechanical ventilation devices are used with company-provided maintenance, then ventilation function is maintained, but maintenance costs are high and reliability is low due to curative rather than preventive approach
Solution Approach 1:
The patent implements a remote monitoring system that continuously collects operational data from ventilation devices and provides feedback to a central management platform. This enables real-time detection of anomalies and predictive maintenance scheduling, transforming the traditional curative maintenance approach into a preventive one, thereby improving reliability while reducing overall maintenance complexity
Solution Approach 2:
The system enables self-diagnostic capabilities through automated monitoring of operational parameters. The ventilation devices can self-report their status and require minimal human intervention for routine monitoring, reducing the complexity of maintenance management while maintaining high reliability through continuous surveillance
2Object-affected harmful factors
If ventilation systems operate continuously at high capacity, then indoor air quality is maintained, but energy losses increase significantly
Solution Approach 1:
The patent implements dynamic control of ventilation systems based on real-time monitoring of indoor air quality parameters such as CO2 levels, temperature, and humidity. The system automatically adjusts fan speeds and airflow rates to match actual ventilation needs, maintaining good indoor air quality while minimizing energy consumption by avoiding unnecessary high-capacity operation
Solution Approach 2:
The system changes operational parameters (fan speed, airflow rate, valve positions) based on measured environmental conditions and occupancy levels. This allows the ventilation system to adapt its performance to actual needs, maintaining air quality standards while reducing energy losses during periods of lower demand
3Reliability
If manual site visits are used for ventilation maintenance, then proper operation can be monitored, but time consumption and costs increase
Solution Approach 1:
The patent replaces manual mechanical inspection with automated electronic monitoring systems. Sensors continuously measure operational parameters (pressure, temperature, flow rates, motor current) and transmit data remotely, eliminating the need for frequent physical site visits while maintaining comprehensive monitoring of ventilation system operation
Solution Approach 2:
The system introduces an intermediary automated monitoring platform that acts between the ventilation devices and human operators. This platform collects, processes, and analyzes operational data, providing remote oversight without requiring direct human presence at the site, thereby reducing time consumption while ensuring reliable operation monitoring
