Solution Overview

Problem

Existing cooling clothing technologies fail to provide effective coolness, convenience in wearing, and ease of washing, leading to issues with user comfort, work safety, and outdoor exercise efficiency.

Innovation Solution

An ICT technology-based piece of cooling clothing that includes an outer cover, a lining, a cooling pad unit with cooling channels, a cooling unit connected to the cooling pad unit, and a controller that can be operated directly by the wearer or automatically through temperature sensing, allowing for collective cooling for group workers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If cooling devices are combined with clothing, then temperature adjustment capability is improved, but convenience in wearing and washing deteriorates

Engineering Contradiction:
Improvetemperature adjustment capabilityVSAvoidconvenience in wearing and washing
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The cooling system is divided into separate modules: a removable cooling pad unit with cooling channels, a detachable controller, and washable clothing layers. This segmentation allows the cooling components to be separated from the clothing for easy washing while maintaining temperature adjustment functionality when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller and cooling pad unit are designed to be extractable from the clothing structure. The controller can be removed from the receiving pocket, and the cooling pad can be detached, allowing the clothing to be washed separately without dealing with electronic components or complex cooling mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If cooling functionality is added to clothing, then work safety and exercise effect are improved, but user comfort deteriorates due to lack of detailed cooling function

Engineering Contradiction:
Improvework safety and exercise effectVSAvoiduser comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cooling pad unit is designed with specific local cooling zones corresponding to key body areas that require cooling for safety and performance. The cooling channels are positioned to target specific regions, providing detailed and effective cooling where needed most rather than uniform cooling across the entire garment.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If cooling pad unit is made flexible, then adaptability to clothing shapes is improved, but manufacturing precision deteriorates

Engineering Contradiction:
Improveadaptability to clothing shapesVSAvoidcooling channel positioning accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The cooling pad unit is constructed using flexible materials and thin-film cooling channels that can conform to various clothing shapes and body contours. The flexible construction allows the cooling channels to maintain their positional accuracy and functional integrity while adapting to different garment geometries and wear conditions.

Inventive Principle:
Principle #30Flexible shells and thin films

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 solution effectively provides coolness to the wearer, increases activity comfort, enhances work safety by allowing automatic temperature regulation, and can be easily integrated with various clothing items.

Implementation Method 1

a cooling unit (400) supplying cool air by being connected to the cooling inflow hole (330) of the cooling pad unit (300) and absorbing heat, which is generated by the cooling pad unit (300), through the cooling outflow hole (350), thereby performing heat dissipation and cooling

Methodology Applied
Scientific EffectHeat dissipation: Conduction (thermal)

Implementation Method 2

the cooling unit (400) is a Peltier element (420) of which a cooling level depends on the intensity of an applied current

Methodology Applied
Scientific EffectPeltier effect: Peltier Effect
