Cooling Insole With Active Air Circulation For Foot Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shoes lack effective ventilation and cooling, leading to discomfort and potential foot diseases due to inadequate heat and moisture dissipation, especially in hot weather.
Innovation Solution
A cooling insole and shoe system featuring a blowing device and air circulation channels that create a ventilation path within the shoe, enhancing airflow circulation and moisture removal through a combination of air holes, hollow layers, and a temperature-sensing fan control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If breathable meshes are used on shoe uppers, then breathability is improved, but ventilation efficiency remains poor and cooling effect is insufficient
Solution Approach 1:
The insole is divided into multiple functional layers including a blowing channel layer, hollow layer, and air hole layer. This segmentation allows air to be distributed through multiple pathways (blowing channels and air holes) simultaneously, significantly improving ventilation efficiency compared to single-layer breathable meshes
Solution Approach 2:
A blowing device (fan) is introduced as an intermediary to actively generate airflow. The fan draws air through the blowing channels and releases it through air holes, creating forced convection that dramatically enhances ventilation efficiency and cooling effect compared to passive breathable meshes
2Temperature
If air circulation is not actively achieved, then device complexity is low, but cooling effect is poor and moisture removal is insufficient
Solution Approach 1:
The system uses a wearable fan powered by a small battery that operates autonomously. The fan automatically draws air through the blowing channels and releases it through air holes, creating self-sustaining air circulation without requiring external power or complex control systems
Solution Approach 2:
The ventilation system transitions from a static passive mesh structure to a dynamic active circulation system. The fan creates moving airflow that adapts to the wearer's needs, dynamically adjusting air circulation to maintain comfortable temperature and moisture levels
3Object-affected harmful factors
If breathable meshes are used, then some ventilation is provided, but airflow circulation cannot be effectively achieved
Solution Approach 1:
The system uses pneumatic principles by employing a fan to generate air pressure differential. The fan draws air in through blowing channels and forces it out through air holes, creating controlled airflow circulation that effectively removes moisture and heat at high speed
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 system significantly improves ventilation and cooling efficiency, keeping the shoe interior dry and breathable, enhancing user comfort and preventing bacterial growth from sweat, while providing uniform cooling to the foot.
Implementation Method 1
the blowing device is communicated to the blowing channel and conveys air to the accommodating space through the blowing channel
Implementation Method 2
the blowing device sucks air from the accommodating space and forms a relatively low pressure region in a region of the accommodating space close to the blowing device
Implementation Method 3
one end of each air hole is configured to be communicated to the accommodating space; the air in the accommodating space forms an internal circulation path, and the air circulation rate is increased

AI summary
The present invention discloses a cooling insole and a cooling shoe. The insole is configured to be connected to a shoe upper and form an accommodating space between with the shoe upper. The cooling insole and the cooling shoe include a supporting member and a supporting insole. The supporting member is provided with a blowing device and a blowing channel. One end of the blowing channel is connected to the blowing device, and the other end is connected to an upper surface of the supporting member. The supporting insole is arranged on the upper surface of the supporting member and forms a hollow layer with the upper surface of the supporting member. The blowing device sucks air from the accommodating space, and the air flows from the hollow layer to the accommodating space through the blowing channel, to accelerate the circulation of the air in the accommodating space.
