Engineering Contradiction Analysis
1Ease of operation
If air purification devices are deployed using random or unguided placement, then deployment simplicity is maintained, but air quality improvement effectiveness deteriorates
Solution Approach 1:
The system performs preliminary actions by conducting computational fluid dynamics simulations and pollutant distribution analysis before actual device deployment. This pre-planning phase identifies optimal device positions and configurations, ensuring that when devices are deployed, they are strategically placed for maximum effectiveness rather than randomly positioned.
Solution Approach 2:
The system creates a virtual three-dimensional representation (digital twin) of the target space that replicates the physical environment's geometry, boundaries, and pollutant sources. This virtual model allows for simulation and optimization of device placement without affecting the actual physical space, enabling informed deployment decisions while maintaining real-world accuracy.
2Reliability
If strategic deployment methods with simulation and optimization are implemented, then air quality improvement effectiveness is improved, but system complexity and computational requirements worsen
Solution Approach 1:
The complex deployment system is segmented into distinct functional modules: a virtual model creation module that builds three-dimensional representations, a simulation module that performs computational fluid dynamics analysis, an optimization module that determines optimal device positions, and a deployment module that implements the plan. This modular segmentation manages complexity by allowing each component to be developed and optimized independently.
Solution Approach 2:
The virtual three-dimensional representation serves as an intermediary between the physical space and the optimization algorithms. Instead of directly analyzing complex real-world geometries and pollutant dynamics, the system works with this simplified virtual model, which captures essential features while enabling efficient computation and iteration.
3Reliability
If more air purification devices are deployed to improve air quality, then air quality improvement effectiveness is improved, but investment cost worsens
Solution Approach 1:
The system optimizes key parameters including device placement coordinates, device orientation angles, device selection from available models, and operational settings such as airflow rates. By systematically varying and optimizing these parameters through simulation, the system identifies the minimum number and configuration of devices needed to achieve target air quality levels, avoiding both under-deployment and wasteful over-deployment.
