Solution Overview

Problem

The existing shoe manufacturing methods require a large number of parts, leading to increased material waste, environmental impact, and low recyclability, while also compromising the fit and functionality of performance shoes due to the use of multiple materials for different areas.

Innovation Solution

A shoe design featuring an upper body made of a main material with embroidered or sewn portions using a chemically-similar thread with a lower melting point, which are then solidified to create high-hardness areas, reducing the number of parts and enabling functional variations without increasing the part count.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large number of parts are used for the upper, then functional variations for individual areas can be achieved, but the production efficiency decreases and material waste increases

Engineering Contradiction:
Improvefunctional variationsVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent combines multiple separate parts into a single integrated upper body made of chemically-similar materials. This merging approach maintains the ability to achieve functional variations through material property differences rather than through part segmentation, thereby improving production efficiency while preserving adaptability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent applies local quality by using chemically-similar materials with different properties (such as different melting points) in different areas of the upper body. This allows functional variations to be achieved through localized material property differences rather than through multiple separate parts, resolving the contradiction between part reduction and functional diversity.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If a large number of parts made of different materials are used, then functional variations can be achieved, but recyclability decreases

Engineering Contradiction:
Improvefunctional variationsVSAvoidenvironmental impact
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent uses chemically-similar materials throughout the upper body, creating a homogeneous material composition from a recycling perspective. This homogeneity enables the entire upper body to be recycled together as a single material type, significantly improving recyclability while still achieving functional variations through differences in material properties like melting point rather than through material diversity.

Inventive Principle:
Principle #33Homogeneity

3Adaptability or versatility

If different parts of different materials are fabricated for individual areas, then functional variations can be achieved, but the number of parts increases

Engineering Contradiction:
Improvefunctional variationsVSAvoidnumber of parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent achieves functional variations by changing physical parameters (such as melting point) of chemically-similar materials rather than by using different chemical materials. This parameter-based differentiation allows the upper body to be constructed as a single integrated part with varying local properties, thereby reducing part count while maintaining functional diversity.

Inventive Principle:
Principle #35Parameter changes
