Mesh-Reinforced Midsole Structure for Compression and Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing footwear designs struggle to balance aesthetic, comfort, and performance demands, particularly in enhancing compression and shear strength in specific regions of the sole structure without compromising flexibility.
Innovation Solution
Incorporating mesh components, such as textiles, between foam components in the sole structure, which can stretch in one or two directions, allowing for tailored compression and shear strength enhancement in specific regions based on their number, placement, and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mesh components are added to increase compression and shear strength, then the strength and durability of the sole structure is improved, but the device complexity and number of components increases
Solution Approach 1:
The patent combines mesh components with foam components to create a composite midsole structure. The mesh provides compression and shear strength while the foam provides cushioning, creating a multi-material composite that achieves enhanced mechanical properties without requiring the entire structure to be complex or rigid.
Solution Approach 2:
The mesh components are strategically placed in specific regions of the midsole where compression and shear strength are most needed, such as high-stress areas during athletic activities. This localized reinforcement approach improves strength where required while keeping other regions simpler and more flexible.
2Strength
If mesh components are used to enhance compression strength, then the durability and support are improved, but the flexibility and comfort may be compromised
Solution Approach 1:
The combination of mesh and foam materials creates a composite structure where the mesh provides compression strength and the foam provides flexibility and cushioning. This composite approach allows both contradictory properties to coexist in different parts of the same component.
Solution Approach 2:
The mesh components are designed to dynamically respond to applied forces, providing compression resistance when needed while allowing flexibility during normal movement. The mesh structure can deform elastically under load and return to its original shape, providing adaptive support rather than rigid constraint.

AI summary
A sole structure for an article of footwear is described. In one example, the sole structure includes first and second foam components and one or more mesh components, e.g., a mesh textile component. The first foam component includes first and second opposing sides, and the second foam component includes first and second opposing sides. The first and second foam components form a stack in the sole structure. The mesh components, e.g., a mesh textile component, are positioned in the stack between and bonded to the second side of the first foam component and the first side of the second foam component.
