Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional air passage layout is used in handheld cleaners, then structural simplicity is maintained, but suction power loss increases and energy consumption rises
Solution Approach 1:
The patent implements a nested air passage structure where the first air passage is positioned within or adjacent to the second air passage, allowing both dust removal airflow and exhaust airflow to be accommodated in a compact, space-efficient manner. This nesting arrangement reduces overall device volume while maintaining separate functional pathways, thereby reducing suction power loss without excessive structural complexity
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning the first air passage and second air passage in different spatial dimensions and orientations. The dust removal chamber and exhaust chamber are arranged to create multi-dimensional airflow pathways, optimizing space utilization and reducing airflow resistance without requiring overly complex structural design
2Use of energy by stationary object
If conventional air passage layout is used in handheld cleaners, then manufacturing simplicity is maintained, but energy consumption increases
Solution Approach 1:
The nested arrangement of air passages reduces the overall device volume and material requirements, leading to manufacturing efficiency improvements. The compact design allows for optimized material usage and assembly processes while maintaining effective separation of dust removal and exhaust functions, thereby reducing energy consumption without significantly increasing manufacturing complexity
Solution Approach 2:
The patent combines the dust removal chamber and exhaust chamber into a integrated housing structure with clearly defined functional zones. By merging related components into unified structures while maintaining functional separation through spatial arrangement, the design achieves manufacturing efficiency and reduces energy consumption without excessive complexity
