Movable Thermal Insulation Layer for Vent Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sportswear fails to maintain body temperature effectively during exercise, leading to discomfort and potential cold-related issues due to inadequate heat dissipation at high temperatures and insufficient warmth at low temperatures.
Innovation Solution
An intelligent fabric system comprising a base layer with vent holes, a thermal insulation layer that can move relative to the base layer, and a controller driven by an instruction generator, which adjusts the thermal insulation layer's coverage of the vent holes based on humidity, sound, or user input to regulate heat retention and dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thick sportswear is worn at low temperature, then warmth is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The thermal insulation layer is designed to be movable relative to the base layer, allowing it to dynamically adjust its position. When the user needs warmth, the thermal insulation layer covers the vent holes; when heat dissipation is needed, the layer moves to expose the vent holes. This dynamic adjustment resolves the contradiction between maintaining warmth and enabling heat dissipation.
Solution Approach 2:
The garment is segmented into distinct functional layers: a base layer with vent holes and a separate movable thermal insulation layer. This segmentation allows each layer to perform its specific function independently - the base layer provides structural support and ventilation pathways, while the thermal insulation layer provides adjustable thermal regulation, resolving the contradiction between warmth and heat dissipation.
2Adaptability or versatility
If thin sportswear is worn, then heat dissipation is improved, but warmth and cold protection deteriorate
Solution Approach 1:
The movable thermal insulation layer can be dynamically positioned to cover or expose the vent holes based on thermal needs. When heat dissipation is required, the layer moves away from the vent holes, allowing thin-garment-like ventilation. When warmth is needed, the layer moves to cover the vent holes, providing insulation. This resolves the contradiction between heat dissipation and cold protection.
3Ease of manufacture
If a fixed thermal insulation structure is used, then manufacturing simplicity is improved, but adaptability to different temperature conditions deteriorates
Solution Approach 1:
The thermal insulation layer is designed with mobility relative to the base layer, enabling it to respond dynamically to changing conditions. The layer can move to cover or expose vent holes based on humidity sensor feedback, allowing the garment to adapt to different temperature and sweat conditions while maintaining a relatively simple overall structure that remains easy to manufacture.
Solution Approach 2:
The system incorporates humidity sensors that detect sweat levels and provide feedback to control the position of the thermal insulation layer. When humidity increases (indicating sweat), the system automatically adjusts the layer to expose vent holes for heat dissipation. When humidity decreases, the layer moves to cover vent holes for warmth. This feedback mechanism enables adaptability without significantly complicating the manufacturing process.

AI summary
An intelligent fabric includes: a base layer with vent holes, a thermal insulation layer on the base layer and capable of being moved relative to the base layer, an instruction generator configured to generate a switch instruction, and a controller connected to the instruction generator and the thermal insulation layer, and configured to control the thermal insulation layer to be moved relative to the base layer in accordance with the switch instruction, so as to switch the thermal insulation layer between a state where the thermal insulation layer covers the vent holes completely and a state where the thermal insulation layer does not cover the vent holes, or among the state where the thermal insulation layer covers the vent holes completely, a state where the thermal insulation layer partially covers the vent holes, and the state where the thermal insulation layer does not cover the vent holes.
