Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvesuction power lossVSAvoidair passage layout complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

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

Inventive Principle:
Principle #7Nested doll (Nesting)

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improveenergy consumptionVSAvoidair passage layout complexity
Core Design Contradiction:
Use of energy by stationary objectVSDevice complexity

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

Inventive Principle:
Principle #7Nested doll (Nesting)

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

Inventive Principle:
Principle #5Merging (Combining)
