Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of cleaning devices is increased to increase processing efficiency, then air purification efficiency is improved, but installation cost and device complexity increase
Solution Approach 1:
The cleaning device is divided into multiple independent gas guiders that can be selectively activated. Each gas guider operates as an independent cleaning unit with its own filtration element, allowing the system to achieve high purification efficiency by activating only the necessary number of units rather than deploying multiple complete devices.
Solution Approach 2:
The flow guiding main body serves multiple functions: it acts as a structural support, a flow distribution system, and a mounting platform for multiple gas guiders. This multi-functionality reduces the need for separate components and decreases overall system complexity and installation cost.
2Productivity
If the CADR of cleaning devices is increased to speed up air pollution processing, then processing efficiency is improved, but operation noise increases
Solution Approach 1:
The total CADR requirement is divided among multiple gas guiders, each operating at a lower individual CADR level. This segmentation allows the system to achieve high overall processing efficiency while each unit operates quietly within acceptable noise tolerance levels.
Solution Approach 2:
The system dynamically adjusts the operating parameters of gas guiders based on real-time air quality monitoring. When air pollution levels are low, the system reduces the operating CADR of active guiders to minimize noise, while maintaining sufficient purification capacity through intelligent control.
3Reliability
If cleaning devices operate continuously to maintain clean air quality, then air purification effectiveness is improved, but energy consumption increases
Solution Approach 1:
The networking controller receives real-time air quality data from sensors and uses this feedback to dynamically adjust the operation of gas guiders. When air quality is good, the system reduces or shuts off cleaning operations; when pollution levels rise, the system activates appropriate numbers of gas guiders to maintain clean air quality.
Solution Approach 2:
Instead of continuous operation, the system employs periodic monitoring and intermittent cleaning actions. The networking controller periodically assesses air quality conditions and activates gas guiders only when needed, achieving reliable air purification while minimizing energy consumption through on-demand operation.
