Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature-adjustable clothing devices lack convenience for user activity, wearable comfort, and ease of washing, and they fail to adapt temperature settings effectively based on 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 to transmit coolness, featuring a controller with a communication module for temperature adjustment based on user input and weather information, and a detachable structure for easy washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If temperature adjustment is based only on body temperature, then cooling function is provided, but adaptability to weather conditions is insufficient
Solution Approach 1:
The system incorporates multiple sensors (body temperature sensor, weather information receiver) that continuously monitor conditions and feed data back to the controller. The controller adjusts cooling output based on this feedback, achieving adaptive temperature control that responds to both internal body temperature and external weather conditions.
Solution Approach 2:
The temperature control system is designed to perform multiple functions: it can adjust temperature based on body temperature alone, weather information alone, or a combination of both. The system universally handles different control scenarios through a single integrated controller that processes various input sources.
2Ease of operation
If cooling units are integrated into clothing, then cooling function is provided, but ease of washing is reduced
Solution Approach 1:
The cooling system is divided into separate modular components: the cooling unit with Peltier elements, the power supply unit with battery, and the clothing fabric. These segments can be detached from each other, allowing the clothing to be washed separately while the electronic cooling components are protected from water damage.
Solution Approach 2:
A detachable connector serves as an intermediary between the cooling unit and the clothing fabric. This connector allows easy attachment and detachment, enabling the clothing to be removed for washing while the cooling unit remains intact and functional.
3Temperature
If cooling fluid circulation is used, then coolness transmission is improved, but device complexity increases
Solution Approach 1:
The system uses a fluid circulation approach where cooled fluid (or air) is circulated through channels in the cooling unit to transfer coolness to the wearer's body. This hydraulic/pneumatic approach efficiently distributes cooling across multiple areas of contact.
Solution Approach 2:
The cooling unit utilizes flexible thermal contact surfaces and thin film structures that conform to the wearer's body contours. This flexibility improves thermal contact efficiency without requiring complex rigid structures, simplifying the overall system design.
