Solution Overview

Problem

Existing air purifiers with annular air outlets lack the ability to control air stream direction, limiting their effectiveness in air distribution and circulation.

Innovation Solution

A wind-direction adjustable air purifier design featuring a housing with an annular air discharge opening, an air guide rotatable in the circumferential direction, and an air stream direction adjusting unit, including an air blocking film or deflection blades, allows for adjustable air stream direction by rotating the air guide and adjusting the air flow path.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If an annular air outlet is used for product design and air discharge, then the air purifier can discharge air in a rotating stream form, but the air stream direction cannot be controlled

Engineering Contradiction:

Improveannular air outlet shapeVSAvoidair stream direction control

Core Design Contradiction:

ShapeVSEase of operation

Solution Approach 1:

The air guide is designed to be rotatable relative to the housing, allowing the air stream direction to be dynamically adjusted. The rotation guide enables the air guide to rotate in the circumferential direction, transforming the static annular outlet into a dynamic system where air discharge direction can be controlled according to different needs.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the air guide is made rotatable to adjust air stream direction, then air distribution control is improved, but the device structure becomes more complex

Engineering Contradiction:

Improveair stream direction adjustment capabilityVSAvoidrotation guide structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The air guide structure is divided into separate components: the air guide itself and the rotation guide. This segmentation allows the air guide to be independently rotated by the rotation guide mechanism, enabling direction control while keeping each component relatively simple in structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotation guide structure serves multiple functions: it supports the air guide, enables rotational movement, and maintains the annular shape of the air outlet. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If deflection blades are added to adjust air flow direction, then air stream control precision is improved, but the device complexity increases

Engineering Contradiction:

Improveair stream direction control precisionVSAvoidair blocking film and deflection blades structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The air guide structure incorporates localized deflection elements (air blocking film and/or deflection blades) at specific positions within the air outlet. These local quality modifications enable precise control of air flow direction without requiring complex changes to the entire air guide structure.

Inventive Principle:

Principle #3Local quality
