Solution Overview

Problem

Existing temperature-adjustable clothing devices lack convenience for user activity, wearable features, and washing convenience, and fail to effectively adapt cooling based on both user body temperature and external weather conditions.

Innovation Solution

An IoT-based cold vest with a cooling unit that uses a circulation of cooled fluid, integrated with a controller, communication module, and temperature collectors to adjust temperature based on user input and weather information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If cooling temperature is set only on the basis of body temperature of users, then the cooling system can be simplified, but the adaptability to external weather conditions deteriorates

Engineering Contradiction:
Improvecooling control system complexityVSAvoidweather adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The cooling control system is designed to perform multiple functions: it monitors both body temperature via temperature collector and external weather conditions via communication module, then integrates both data sources to comprehensively control the cooling units. This multi-functional approach resolves the contradiction by maintaining system adaptability while managing complexity through integrated control logic.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements feedback control by continuously monitoring body temperature through temperature collector and weather conditions through communication module, then using this feedback information to dynamically adjust cooling unit operation. This feedback mechanism enables the system to adapt to changing conditions while maintaining reasonable control complexity through automated regulation.

Inventive Principle:
Principle #23Feedback

2Reliability

If cooling members are made integrated and fixed, then the cooling effectiveness is improved, but the convenience for washing and maintenance deteriorates

Engineering Contradiction:
Improvecooling effectivenessVSAvoidwashing convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cooling system is segmented into detachable components: cooling units with cooling members can be separated from the main clothing body. This segmentation allows the cooling members to maintain their integrated structure for cooling effectiveness while enabling easy removal for washing and maintenance, thus resolving the contradiction between reliability and ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a fixed integrated structure to a dynamic detachable structure. The cooling units can be attached or detached from the clothing body as needed, providing both the cooling effectiveness of an integrated system and the washing convenience of separable components through this dynamic configuration capability.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If cooling members are made rigid for structural stability, then the cooling area coverage is improved, but the flexibility and comfort for user activity deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidactivity flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The cooling members are constructed using flexible materials such as flexible printed circuit boards and flexible heat dissipation members instead of rigid structures. This flexible construction maintains structural stability for cooling effectiveness while allowing the cooling members to bend and conform to body movements, thus resolving the contradiction between structural stability and activity flexibility.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The system employs composite material construction combining flexible substrates with functional cooling elements. The flexible printed circuit boards and flexible heat dissipation members create a composite structure that provides both the structural stability needed for cooling performance and the flexibility required for user comfort during various activities.

Inventive Principle:
Principle #40Composite materials
