Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air conditioners or air cleaners are utilized to improve indoor air quality, then air quality can be improved, but it is not easy to control indoor air quality due to multiple affecting factors including outdoor air quality, air conditioning, and indoor pollution sources
Solution Approach 1:
The system segments the indoor space into multiple detection zones with multiple gas detection devices distributed throughout, allowing localized identification of pollution sources. This segmentation enables targeted response to specific areas rather than treating the entire space uniformly, improving control reliability while managing complexity through modular deployment
Solution Approach 2:
The system implements real-time feedback through continuous monitoring of air quality parameters by gas detection devices, with intelligent computation analyzing the data and automatically adjusting filtering device operations. This closed-loop feedback mechanism dynamically responds to changing conditions from multiple pollution sources, maintaining reliable air quality control despite system complexity
2Reliability
If gas detection devices and filtering devices are deployed throughout the indoor space, then air pollution can be detected and filtered, but the device complexity and cost increase
Solution Approach 1:
The system employs movable filtering devices that can dynamically reposition themselves based on real-time pollution location data from gas detection devices. This dynamic capability allows the system to concentrate filtering resources where needed rather than distributing fixed filters throughout the entire space, maintaining reliable pollution removal while reducing the total number of devices required
Solution Approach 2:
The filtering devices are designed with multi-functionality, combining gas detection capabilities, intelligent computation, and filtering operations in single units. This universality allows the same device to perform multiple functions, reducing the need for separate specialized devices and thereby reducing overall system complexity while maintaining comprehensive pollution detection and filtering capabilities
3Productivity
If filtering devices are positioned away from air pollution location, then filtering efficiency is reduced, but continuously moving filtering devices increases energy consumption
Solution Approach 1:
The movable filtering devices operate using periodic action, alternating between movement mode and stationary filtering mode. The devices move to pollution locations only when necessary based on detection data, then remain stationary to perform filtering operations. This periodic cycle of movement and filtering reduces energy consumption compared to continuous movement while maintaining high filtering efficiency by positioning devices optimally during filtering phases
Solution Approach 2:
The system performs preliminary action by having gas detection devices continuously monitor and identify pollution locations before deploying movable filtering devices. This advance detection and positioning planning allows filtering devices to move directly to optimal locations without unnecessary traversal, reducing energy consumption while ensuring they are positioned correctly for maximum filtering efficiency when they arrive

AI summary
A system for detecting and cleaning indoor air pollution includes gas detection devices and filtering devices. The gas detection devices are adapted to detect a qualitative property and a concentration of an air pollution and output an air pollution data to perform an intelligent computation. The filtering devices are physical-typed or chemical-typed for filtering the air pollution. The filtering devices include one or more movable filtering devices, and the movable filtering device includes a gas detection device. After the intelligent computation is performed to locate an air pollution location, a control command is transmitted to the movable filtering device selectively and intelligently, and the movable filtering device receives the control command and is moved to the air pollution location. Therefore, the movable filtering device allows the air pollution data to approach to a non-detection state, thus a gas in the indoor space is cleaned to a safe and breathable state.
