2.5D Shoe Models for Accurate 3D Representation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shoe design technologies lack an efficient method to transition 2D designs into 3D models while accounting for material-specific distortions, making it difficult for shoe designers to create accurate 3D representations from 2D interfaces.
Innovation Solution
The implementation of a 2.5D shoe design system that generates 2.5D shoe models by adding layering data to 2D shoe shell patterns, allowing for the tracking of thickness and material data, and subsequently wrapping these models into 3D representations for physical construction, while accounting for material-based distortions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 2D shoe shell patterns are used for design, then ease of operation is improved, but manufacturing precision deteriorates due to material-specific distortions
Solution Approach 1:
The patent introduces a 2.5D intermediate representation that adds thickness information to traditional 2D shoe shell patterns. This 2.5D model serves as a bridge between 2D design interfaces and 3D manufacturing models, capturing material layering and thickness data while maintaining the ease of 2D pattern editing. The 2.5D model includes layered material information that can be accurately wrapped into 3D representations, thus resolving the contradiction between ease of 2D operation and precision of 3D manufacturing.
2Manufacturing precision
If traditional 3D CAD design is used, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the shoe design process into distinct components: 2D shell patterns, 2.5D layered material models, and 3D wrapped representations. Each component handles specific aspects of the design, allowing designers to work with simplified 2D patterns while the system automatically manages the complex 3D geometry and material layering. This segmentation reduces the apparent complexity of the CAD system while maintaining manufacturing precision.
Solution Approach 2:
The 2.5D shoe model acts as an intermediary between 2D design inputs and 3D manufacturing outputs. It captures thickness and material layering information in a structured format that can be automatically wrapped into accurate 3D models, eliminating the need for designers to directly manipulate complex 3D CAD geometry while still achieving high manufacturing precision.
3Productivity
If 2D designs are converted directly to 3D models, then productivity is improved, but manufacturing precision deteriorates due to lack of material layering data
Solution Approach 1:
The patent performs preliminary action by capturing material layering and thickness information during the 2D design phase itself. The 2.5D model stores this information in a structured format before the 3D wrapping process, ensuring that material accuracy is built into the design data structure early in the workflow. This allows rapid conversion to 3D while maintaining precision, as the material information is already organized and ready for accurate representation.

AI summary
Systems, methods, logic, and devices may support shoe design through 2.5-dimensional (2.5D) shoe models. In some examples, a system may include a 2D shoe shell pattern engine configured to access a 2D shoe shell pattern, the 2D shoe shell pattern generated for shoe design. The system may also include a 2.5D shoe model engine configured to generate a 2.5D shoe model by placing shoe design elements provided by a user onto the 2D shoe shell pattern of the shoe, including by adding 2.5D layering data for each shoe design element placed on the 2D shoe shell pattern to form the 2.5D shoe model, and wrap the 2.5D shoe model into a 3D shoe model for construction of a physical shoe from the 3D shoe model.
