Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional air purification methods are used, then air quality improves gradually, but the purification speed is slow and cannot quickly remove pollutants
Solution Approach 1:
The system performs preliminary detection of air pollution sources and concentrations before initiating full purification. Gas detection devices continuously monitor the indoor environment, identifying pollution locations in advance, allowing the system to prepare and direct filtration resources to the most critical areas first, thereby accelerating overall purification speed while maintaining reliability
Solution Approach 2:
The system implements real-time feedback through continuous monitoring of air quality parameters by gas detection devices. The central control unit receives detection data, evaluates current air quality status, and dynamically adjusts the operation of air-exchanging filtration devices. This closed-loop feedback mechanism ensures that purification efforts are continuously optimized to maintain reliable pollution removal while maximizing purification speed
2Area of stationary object
If multiple air-exchanging filtration devices are deployed throughout the indoor space, then air purification coverage improves, but system complexity and cost increase
Solution Approach 1:
Instead of uniformly distributing identical filtration devices throughout the space, the system places air-exchanging filtration devices at strategically selected locations based on detected pollution sources and air flow patterns. Each device is positioned to maximize its impact on specific pollution-prone areas, achieving comprehensive coverage while minimizing the total number of devices required, thus reducing system complexity
Solution Approach 2:
The air-exchanging filtration devices are designed with multi-functional capabilities, serving both as air intake devices and as filtration units. The same device structure performs multiple functions: drawing in polluted air, filtering particulate matter through HEPA filters, removing gases through activated carbon, and releasing purified air. This multi-functionality reduces the need for separate specialized devices, simplifying the overall system while maintaining broad purification coverage
