Solution Overview

Problem

Existing vertical air conditioners with swing blades suffer from poor stability and inaccurate wind direction control due to long swing blades prone to deformation, and limited directional air control, especially in elongated air outlets.

Innovation Solution

A modular vertical air conditioner design featuring segmented swing blades with separate driving mechanisms and an independent air handling base that increases air outflow range and stability by reducing the length of individual swing blades and allowing independent operation of additional air handling functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the air outlet is elongated to increase air supply coverage, then the air supply range is improved, but the swing blades become relatively long resulting in poor stability and inaccurate wind direction control

Engineering Contradiction:
Improveair supply rangeVSAvoidwind direction control accuracy
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The swing blade is divided into multiple independent segmented blades (first segmented swing blade and second segmented swing blade) arranged along the elongated air outlet. Each segmented blade has a reduced length compared to a single long blade, improving stability and reducing deformation while maintaining coverage of the extended air outlet area.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If the swing blade length is increased to cover the elongated air outlet, then the air supply coverage is improved, but the swing blade becomes prone to deformation under hot and cold wind impact

Engineering Contradiction:
Improveair outlet coverageVSAvoidresistance to deformation
Core Design Contradiction:
Area of stationary objectVSStrength

Solution Approach 1:

The long swing blade is segmented into multiple shorter blades that can independently withstand wind forces. This segmentation reduces the moment arm and structural stress on each individual blade, preventing deformation while collectively covering the full air outlet area.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the swing blade is made as a whole structure to simplify the driving mechanism, then the device complexity is reduced, but the directional reliability is poor as air can only be forced in one direction

Engineering Contradiction:
Improvedriving structure simplicityVSAvoiddirectional control reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The swing blade system is segmented into multiple independently controllable blades, each with its own driving mechanism. This allows different segments to be directed toward different targets simultaneously, improving directional reliability while maintaining manageable complexity through modular control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each segmented swing blade can be dynamically adjusted to different angles and positions independently, allowing the system to adapt to varying directional requirements. This dynamic control enables reliable multi-directional air distribution rather than being forced into a single direction.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The segmented swing blade design enhances stability and accuracy of wind direction control while enabling multi-directional air flow and additional air handling functions without affecting the original air conditioner structure.
