Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a mechanical ventilation system is used to control radon levels, then radon removal effectiveness is improved, but acquisition costs, operating costs, and maintenance costs increase considerably
Solution Approach 1:
The patent extracts the core function of radon removal from complex mechanical ventilation systems and implements it through a simple window actuation mechanism controlled by radon sensors, eliminating the need for expensive mechanical components while maintaining radon removal effectiveness
Solution Approach 2:
The invention replaces expensive, complex mechanical ventilation systems with inexpensive window actuators and sensors, using cheap components to achieve the same radon control function without requiring continuous maintenance of complex machinery
2Productivity
If a mechanical ventilation system is deployed to manage indoor climate, then air exchange capability is improved, but energy consumption and operating costs increase
Solution Approach 1:
The system uses passive natural convection and wind-driven air exchange through opened windows, eliminating the need for energy-consuming mechanical fans while maintaining effective air exchange capability for radon removal and climate control
Solution Approach 2:
The patent replaces active mechanical ventilation systems with passive atmospheric forces (wind pressure, buoyancy) to drive air exchange, substituting mechanical energy consumption with natural physical processes
3Measurement precision
If multiple sensors are provided for measuring different air parameters, then measurement accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The system employs sensors that can detect multiple parameters (radon concentration, temperature, humidity) and uses a single integrated control unit that processes all sensor inputs to make unified window control decisions, reducing overall system complexity while maintaining comprehensive monitoring capability
4Device complexity
If automated window ventilation is implemented, then operating costs are reduced, but control precision for humidity management may worsen
Solution Approach 1:
The system continuously monitors humidity levels through sensors and adjusts window actuation in real-time based on feedback from humidity measurements, maintaining precise humidity control while using automated low-cost operation
Solution Approach 2:
The window actuation system dynamically adjusts opening angles and positions based on real-time sensor data for radon, temperature, and humidity, enabling precise control of air exchange rates to manage humidity while maintaining low operating costs
