Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the filter is mounted in a conventional position, then the structure is simple, but the air purification capacity is reduced

Engineering Contradiction:
Improveair purification capacityVSAvoidfilter mounting structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The filter surface is configured in an inclined manner relative to the air flow direction, transitioning from a conventional parallel mounting to an angled orientation. This dimensional change allows the filter to capture contaminants more effectively across a broader area, thereby increasing air purification capacity while maintaining structural simplicity through the single inclined plane design.

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

2Ease of operation

If the suction unit is fixed, then the structure is stable, but filter replacement is inconvenient

Engineering Contradiction:
Improvefilter replacement convenienceVSAvoidsuction unit stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The suction unit is designed with a pivotal connection that allows it to rotate between a closed position (providing structural stability during operation) and an open position (enabling convenient filter replacement). This dynamic mechanism transforms the previously static suction unit into a movable component that maintains stability when needed while facilitating easy maintenance access.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the air purifier occupies large space, then the air purification capacity is maximized, but the installation area is increased

Engineering Contradiction:
Improveair purification capacityVSAvoidinstallation area
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The air purifier utilizes a three-dimensional cylindrical configuration with the filter surface inclined at an angle to the air flow direction. This spatial arrangement allows the filter to process a larger volume of air through its inclined surface area without increasing the device's horizontal footprint, thereby maximizing air purification capacity within a compact installation space.

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

Solution Approach 2:

The air purifier employs a cylindrical body with curved surfaces, including the inclined filter surface that follows a portion of the cylindrical curvature. This spherical/curved geometry allows for efficient space utilization, enabling the filter to capture air from multiple directions and maximize purification capacity while maintaining a compact, space-efficient form factor suitable for various installation locations.

Inventive Principle:
Principle #14Spheroidality (Curvature)
