Air-conditioning garment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning garments fail to secure sufficient wind velocity inside the garment to effectively evaporate sweat and cool the body, particularly in high-temperature environments.
Innovation Solution
The air-conditioning garment incorporates at least one centrifugal fan attached to the lower back part with air outlets configured to direct airflow upward or obliquely upward, ensuring sufficient wind velocity is maintained up to the shoulders, and additional fans can be arranged side by side to cover a wider range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If outside air is taken into the garment main part using fans, then cooling effect is improved, but wind velocity inside the garment is insufficient to effectively evaporate sweat
Solution Approach 1:
The patent changes the airflow direction parameter by configuring air outlets to direct air upward or obliquely upward instead of horizontally or downward. This parameter change ensures that the air flow reaches the shoulders and upper body areas, maintaining sufficient wind velocity for sweat evaporation while providing cooling effect.
Solution Approach 2:
The patent introduces a vertical dimension to the airflow by directing air upward through specifically designed air outlets. This dimensional change allows the cooling air to reach the shoulders and upper body effectively, solving the problem of insufficient wind velocity in the vertical direction while maintaining horizontal coverage.
2Speed
If air outlets are configured to direct air upward, then wind velocity reaches the shoulders, but the coverage area may be limited
Solution Approach 1:
The patent segments the air outlet configuration into multiple directional outlets (upward and obliquely upward) to cover different areas. This segmentation allows the air flow to be distributed effectively across the shoulders and upper body, expanding the cooling coverage area while maintaining sufficient wind velocity at each segment.
Solution Approach 2:
The patent employs asymmetric air outlet configurations with different blowing directions (upward and obliquely upward) to optimize coverage. This asymmetric design ensures that air flow reaches various parts of the upper body effectively, expanding the cooling area while maintaining high wind velocity in critical areas like the shoulders.
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
This configuration secures a consistent and sufficient wind velocity up to the shoulders, preventing heat strokes by effectively evaporating sweat and maintaining cooling over a wider area.
Implementation Method 1
the at least one fan may be a centrifugal fan
Implementation Method 2
a certain wind velocity is required to evaporate sweat

AI summary
An air-conditioning garment includes a garment main part that is worn on the upper body of a wearer, and two fans that are attached to a lower part of a back part of a garment main part, and configured to feed outside air into the inside of the garment main part. Each of the two fans includes a fan main body and a case that houses the fan main body and includes two air outlets. The two air outlets are formed so that their blowing directions are restricted to being upward or obliquely upward. The two air outlets are formed in such a manner that their blowing directions have an upwardly-opened V-shape.
