Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional footwear assembly methods involve bonding or affixing multiple layers, which can be cumbersome and lack flexibility in design and materials.
Innovation Solution
A 3D printed platform with an internal channel and bevels is used to assemble the upper and sole components without bonds or fixtures, utilizing a string lasting method to secure the upper to the platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional bonding or affixing methods are used to assemble multiple layers, then structural integrity is achieved, but the assembly process becomes cumbersome and design flexibility is reduced
Solution Approach 1:
The patent divides the footwear into distinct functional components (upper, sole components) that can be manufactured separately using different materials and processes, then assembled through a simplified bonding process. This segmentation allows each component to be optimized independently while simplifying the overall assembly compared to traditional multi-layer construction.
Solution Approach 2:
The patent combines multiple traditional layers into fewer integrated components. By using a simplified bonding process to attach the upper to sole components, it merges what would traditionally require multiple separate bonding operations and intermediate layers into a more efficient assembly process.
2Adaptability or versatility
If traditional layering methods are used, then structural support is provided, but the use of single-material constructions is limited
Solution Approach 1:
The patent applies different materials to different components based on their specific functional requirements. The upper can be made from materials optimized for comfort and flexibility, while sole components can use materials optimized for durability and ground contact. This local quality approach allows single-material constructions within each component while maintaining overall structural integrity through strategic material selection at each location.
Solution Approach 2:
The patent utilizes composite material constructions where different materials are combined in the upper and sole components. Each component can incorporate multiple materials with complementary properties, allowing the footwear to achieve both structural integrity and material versatility. The bonding process then integrates these composite components into a unified structure.
3Productivity
If multiple separate layers are bonded together, then functional requirements are met, but the assembly time and productivity are reduced
Solution Approach 1:
The patent prepares components for assembly in advance by pre-forming the upper and sole components with predetermined bonding surfaces. This preliminary action allows the actual bonding process to be faster and more efficient, as components are ready for immediate attachment without requiring complex alignment or preparation during assembly.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate layers and complex bonding operations from traditional footwear assembly. By directly bonding the upper to sole components without requiring multiple intermediate layers or sequential bonding steps, it significantly reduces assembly time and improves productivity.

AI summary
The present disclosure relates to a platform for footwear. The platform includes bevels and an internal channel for assembling an upper with the platform. A first bevel is defined in a first side portion of the platform and is configured to receive a portion of a first upper side. A second bevel is defined in a second side portion of the platform and is configured to receive a portion of a second upper side. An internal channel is positioned within the platform and extends between the first bevel and the second bevel. The internal channel is configured to receive a fastener to assemble the upper with the platform. The platform may also include a slot for receiving an edge portion of a sock liner to assemble the sock liner with the platform.
