Elastic String Shoe Upper Weaving for Breathable Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional shoe uppers lack breathability and ventilation due to their thick, woven structure, causing discomfort to the wearer.
Innovation Solution
A novel weaving method using a water-soluble fabric base layer and thermoplastic elastic strings, which are heat-pressed and bonded at intersections, creating ventilation holes and allowing for easy detachment and customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional woven structure is used, then structural strength is maintained, but breathability deteriorates
Solution Approach 1:
The shoe upper is divided into multiple independent elastic string layers (first elastic string layer, second elastic string layer, etc.) that are woven separately and then combined. This segmentation allows each layer to be optimized for breathability while maintaining overall structural integrity through the layered construction.
Solution Approach 2:
The patent combines elastic strings with water-soluble fabric base layers to create a composite structure. The elastic strings provide breathability and flexibility, while the water-soluble base layer provides structural support during manufacturing and is later removed, leaving a breathable elastic string upper.
2Productivity
If thermoplastic elastic strings are heat-pressed and bonded, then manufacturing efficiency is improved, but ease of operation deteriorates
Solution Approach 1:
A water-soluble fabric base layer is introduced as an intermediary carrier during the heat-pressing process. This intermediary allows the elastic strings to be bonded efficiently while providing a temporary support structure that can be easily removed later by dissolving in water, thus maintaining ease of operation.
Solution Approach 2:
The water-soluble fabric base layer is designed as a disposable temporary carrier that serves its purpose during manufacturing (providing support for heat-pressing) and then is easily discarded by dissolving in water, enabling both efficient manufacturing and easy removal without affecting the final product.
3Ease of manufacture
If water-soluble fabric base layer is used, then ease of manufacture is improved, but loss of substance increases
Solution Approach 1:
The water-soluble fabric base layer is extracted from the final product by dissolving it in water after the elastic strings are bonded. This extraction removes the temporary carrier material that was only needed during manufacturing, allowing ease of manufacture without permanent material waste in the final shoe upper.
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
Enhances breathability and manufacturing efficiency while enabling easy removal and customization of shoe uppers.
Implementation Method 1
each of the thermoplastic elastic strings is heat-pressed and bonded at intersection points or overlap points
Implementation Method 2
The use of water-soluble fabric base layer as a carrier and water-soluble threads for positioning the thermoplastic elastic strings enables easy detachment of the fabric base layer and threads from the shoe upper after heat pressing. Simply dissolving them in water facilitates removal

AI summary
The object of the present disclosure is to address the shortcomings in the prior art by providing a novel weaving shoe upper with elastic strings, aiming to offer a structure that is simple and provides good breathability. The shoe upper includes a water-soluble fabric base layer and at least one thermoplastic elastic-string layer with thermoplastic elastic strings wound back and forth on the water-soluble fabric base layer. Each of the thermoplastic elastic strings is heat-pressed and bonded at the intersection or overlap points between thermoplastic elastic strings.
