Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If filters are disposed on both sides of housing to correspond to air inlets, then air purification efficiency is improved, but product design diversity is limited
Solution Approach 1:
The patent applies asymmetry by configuring filters and air inlets in non-symmetric arrangements. Instead of symmetric placement on both sides of the housing, the filter and air inlet are positioned asymmetrically, allowing for diverse product designs while maintaining effective air purification through optimized airflow paths.
2Device complexity
If control setting values are fixed in manufacturing, then device complexity is reduced, but operational performance optimization is limited
Solution Approach 1:
The patent implements dynamics by making control setting values adjustable and adaptable based on the mounted filter's characteristics. Instead of fixed control settings, the system dynamically adjusts operational parameters according to the specific filter type and capacity, enabling optimized performance while maintaining relatively simple device architecture through automated detection and adaptation.
3Device complexity
If a single suction structure is used, then device complexity is reduced, but air purification efficiency is limited
Solution Approach 1:
The patent applies universality by designing a single blower structure that performs multiple functions effectively. The single suction structure is optimized to handle various airflow requirements and filter configurations, achieving high air purification efficiency through optimized airflow paths and multi-directional discharge capabilities rather than requiring complex multi-suction structures.
