Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shoe uppers face challenges in providing optimal stability and stretching while maintaining comfort, and their manufacturing processes are complex and costly, especially when producing different sizes.
Innovation Solution
The shoe upper features a knitted inner layer with integrated knitted functional elements that provide stability and stretching capabilities without compromising comfort, where the outer layer covers these elements, eliminating the need for additional components and simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional multi-component uppers are used to provide stability and stretching, then functional properties are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent integrates multiple functional elements (stability ribs, stretching zones, ventilation channels) directly into the knitted upper structure itself, eliminating the need for separate components. The knitted construction allows all functional zones to be formed in a single manufacturing process, resolving the contradiction between functional versatility and manufacturing complexity
Solution Approach 2:
The knitted upper serves multiple functions simultaneously: it provides structural stability through integrated ribs, enables stretching through elastic knitted zones, and facilitates ventilation through porous structures. This multi-functionality within a single component reduces overall device complexity while maintaining adaptability
2Reliability
If additional functional elements are added to enhance stability and stretching, then performance is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent combines stability ribs, stretching zones, and ventilation features into a single integrated knitted upper that is manufactured in one continuous process. This eliminates the need to separately manufacture and assemble multiple functional components, thereby improving ease of manufacture while maintaining reliability
Solution Approach 2:
The knitted construction allows functional properties to be adjusted by changing knitting parameters (stitch type, yarn selection, needle configuration) rather than adding physical components. This enables customization of stability and stretching performance through process parameters, simplifying manufacturing
3Duration of action of stationary object
If multiple layers and components are used to provide functional properties, then durability is improved, but manufacturing cost increases
Solution Approach 1:
The patent consolidates multiple functional layers into a single knitted upper structure, reducing the total quantity of materials required. The integrated design eliminates redundant layers while maintaining durability through the inherent strength and flexibility of the knitted construction
Solution Approach 2:
The knitted upper utilizes composite yarns combining different fiber types (synthetic and natural fibers) to achieve enhanced durability, breathability, and elasticity within a single material system, reducing the need for multiple separate material layers
