Solution Overview

Problem

Wall mounted air conditioners with swing blades mounted at the upper portion of the air outlet face limitations in air discharging angle adjustment and comfort level due to uneven air output, resulting in inefficient air flow and reduced indoor comfort.

Innovation Solution

A wall mounted air conditioner design with a swing blade mechanism positioned at the lower portion of the air outlet, featuring a base, transmission mechanism, and multiple swing blades connected via an elastic connecting part and a manual adjusting device, allowing for flexible angle adjustment and easy detachment for maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If swing blades are mounted at the upper portion of the air outlet, then the structure is simple, but the air discharging angle adjustment is limited and comfort level is reduced

Engineering Contradiction:
Improveair discharging angle adjustmentVSAvoidswing blade mechanism structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent inverts the conventional mounting position of swing blades from the upper portion to the lower portion of the air outlet. This inversion allows the swing blades to effectively utilize the larger air output at the lower portion, significantly improving air discharging angle adjustment capability and comfort level while maintaining structural simplicity.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces a vertical dimension consideration by positioning swing blades at different heights (lower portion) of the air outlet. This dimensional change enables the swing blades to interact more effectively with the air flow pattern, achieving broader angle adjustment and improved air distribution throughout the room.

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

2Ease of repair

If swing blade mechanism components are fixed permanently, then structural stability is high, but maintenance and cleaning efficiency is low

Engineering Contradiction:
Improvemaintenance efficiencyVSAvoidmechanism structural stability
Core Design Contradiction:
Ease of repairVSStability of the object's composition

Solution Approach 1:

The patent segments the swing blade mechanism into detachable components including the swing blade assembly and the air outlet seat. This segmentation allows individual components to be easily removed for maintenance and cleaning while maintaining structural stability during operation, significantly improving maintenance efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a dynamic mounting system where the swing blade assembly can be detached and reattached to the air outlet seat. This dynamic design provides the flexibility needed for easy maintenance while ensuring stable operation when assembled, resolving the contradiction between fixed stability and maintenance accessibility.

Inventive Principle:
Principle #15Dynamics
