Separable Footwear Outsole with Midsole Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional footwear lacks flexibility and recyclability, as the sole structure is permanently attached to the upper, making it difficult to replace worn components and recycle materials efficiently.
Innovation Solution
The design features a separable midsole and outsole structure with apertures in the outsole allowing the midsole protrusions to extend through, enabling separate cleaning and replacement of components, and facilitating customization and recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the sole structure is permanently attached to the upper, then the footwear has structural stability, but the flexibility and recyclability are reduced
Solution Approach 1:
The sole structure is divided into multiple separable components: an outsole and a midsole, which can be detached from each other and from the upper. This segmentation allows each component to be independently replaced, cleaned, or recycled, thereby improving flexibility and adaptability while maintaining structural stability when assembled.
Solution Approach 2:
The footwear transitions from a static, permanent attachment to a dynamic, removable connection system. The separable sole components can be inserted and removed through openings in the upper, enabling users to adapt the footwear to different activities or preferences while maintaining stability during use.
2Strength
If the sole structure is permanently attached to the upper, then the structural integrity is maintained, but the ease of replacement and recycling is reduced
Solution Approach 1:
The sole structure is segmented into replaceable components (outsole and midsole) that can be independently removed and replaced. This allows users to replace only the worn portions rather than the entire sole assembly, improving ease of repair and recycling while maintaining structural integrity through proper reattachment.
Solution Approach 2:
The separable design enables selective discarding and recovering of specific components. Worn outsoles or midsoles can be removed and replaced while retaining the upper and other intact components, facilitating recycling and reducing waste while maintaining structural integrity through reuse of quality components.
3Ease of manufacture
If the sole structure is permanently attached to the upper, then the manufacturing simplicity is maintained, but the ease of cleaning and maintenance is reduced
Solution Approach 1:
The sole structure is segmented into separable components that can be easily detached for cleaning and maintenance. This allows users to access and clean each component individually, improving ease of operation and maintenance while the manufacturing process remains relatively simple through standardized connection interfaces.

AI summary
An article of footwear is disclosed that includes an upper, an outsole, and a midsole. The upper is configured to receive a foot, and the outsole is secured to the upper. The outsole defines a plurality of apertures extending entirely through the outsole. In addition, the outsole has a ground-engaging surface positioned at a first elevation. The midsole is positionable such that a lower surface of the midsole extends into the apertures of the outsole and is exposed by the apertures.
