Fan-Enabled Garment Air Layer for Heat Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan-equipped garments with titanium sputtering have limited sunlight blocking and heat-insulating effects, as the titanium coating is expensive, wears off quickly, and provides inadequate protection against high outside air temperatures.
Innovation Solution
A garment body with a fan mount hole, a front fabric that can be inflated with air introduced by the fan, and a heat insulation layer on the back side made of a material that holds air, along with adjustable air-discharge parts to optimize airflow and pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If titanium sputtering is applied to polyester fabric to block sunlight, then sunlight blocking effect is improved, but the coating wears off quickly due to friction with underwear
Solution Approach 1:
The patent removes the titanium sputtering coating from the garment structure entirely, replacing it with an air layer barrier system. This extracts the problematic coating component while maintaining the sunlight blocking function through a different mechanism (air layer + fan cooling).
Solution Approach 2:
The patent introduces an air layer as an intermediary substance between the outer garment and the wearer's body. This air layer serves as a thermal and solar radiation barrier, replacing the need for direct coating application on the fabric.
2Temperature
If titanium sputtering is used for heat insulation, then heat blocking is improved, but the cost increases significantly
Solution Approach 1:
The patent replaces the expensive titanium sputtering process with a cost-effective air layer system that can be easily integrated into standard garment manufacturing. The air layer requires no special coating materials or complex manufacturing processes.
Solution Approach 2:
The patent changes the fundamental parameter of heat blocking from material-based (titanium coating) to structure-based (air layer). This parameter change transforms the heat insulation mechanism from reflective coating to convective barrier, significantly reducing manufacturing costs.
3Temperature
If the garment structure is made simple without air discharge mechanisms, then device complexity is reduced, but heat insulation effectiveness decreases when outside temperature exceeds skin temperature
Solution Approach 1:
The patent introduces dynamic air discharge mechanisms (collar and sleeve openings with adjusters) that allow the garment to adapt its structure based on thermal conditions. These dynamic elements enable active heat management while maintaining relatively simple overall garment design.
Solution Approach 2:
The air discharge mechanisms serve multiple functions: they enable heat release when outside temperature exceeds skin temperature, allow adjustable ventilation control, and maintain the integrity of the air layer system. This multi-functionality justifies the added structural elements.
