Solution Overview

Problem

Conventional air conditioners often have limited air outlet range and can blow air directly onto people, causing discomfort, especially when mounted near beds, leading to health issues due to concentrated and forceful airflow.

Innovation Solution

A swing assembly with rotatable swing blades connected to a mounting plate and driven by a link mechanism, allowing the blades to rotate up to 90 degrees, maximizing airflow coverage and reducing direct blowing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the air conditioner blows air in one direction for a long time, then the airflow is concentrated and forceful, but the temperature in every corner of the room cannot meet people's needs and direct blowing harms health

Engineering Contradiction:
Improveairflow coverageVSAvoiddirect blowing on human body
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the dynamics principle by implementing swing blades that can rotate and change direction dynamically. The swing assembly includes multiple blades connected to a rotating mechanism that allows them to sweep across different angles, transforming the static single-direction airflow into dynamic multi-directional airflow coverage throughout the room.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies segmentation by dividing the airflow into multiple streams through multiple swing blades. Each blade independently guides airflow in slightly different directions, segmenting the concentrated forceful airflow into distributed softer airflow patterns that cover broader areas without direct blowing on occupants.

Inventive Principle:
Principle #1Segmentation

2Temperature

If conventional air conditioners are mounted at the head of a bed, then they can cool the room effectively, but the blowing directly on human body while sleeping is more harmful to people's health

Engineering Contradiction:
Improveroom cooling effectivenessVSAvoiddirect blowing on sleeping persons
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The swing blades dynamically adjust airflow direction to avoid direct blowing on sleeping persons while maintaining room cooling. The rotating mechanism allows the airflow to sweep across the room rather than directly targeting the bed area, providing temperature control without harmful direct exposure.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the air conditioner blows a large amount of air in a concentrated mode, then cooling capacity is high, but the wind power is forceful and causes discomfort

Engineering Contradiction:
Improvecooling capacityVSAvoidforceful wind power
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The swing assembly segments the concentrated airflow into multiple directional streams. By distributing the total airflow across multiple blades sweeping in different directions, the forceful wind power is divided into softer individual streams that maintain overall cooling capacity without causing discomfort.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from one-dimensional concentrated airflow to multi-dimensional distributed airflow. The swing blades introduce angular variation, spreading airflow in multiple spatial dimensions rather than a single concentrated direction, thereby reducing forceful wind power while preserving cooling effectiveness.

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

AI summary

The present disclosure provides a swing assembly and an air conditioning device provided with the swing assembly. The swing assembly includes a plurality of swing blades, a link, and a mounting plate. The plurality of swing blades are parallel to an extending direction of an air outlet, spaced apart in a length direction of the mounting plate, and all connected to the link. The link is configured to drive the swing blades to rotate around an axial direction. When the air comes from the air conditioner, the swing blade can change left and right directions of the airflow, and the air blown out from the air conditioner can have maximized coverage of the entire house and become soft to some extent, avoiding the direct blowing that makes a person feel uncomfortable.
