Shoe Shape and Projection Alignment for Realistic Design Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for modifying the design of apparel, such as shoes, are inflexible and lack realism, as they require rebuilding prototypes for each design change and struggle to provide a meaningful evaluation of designs on a computer screen.
Innovation Solution
An apparatus and method that allow for reversible modification of a shoe's appearance by changing its shape through attachable and removable components, with automatic adjustment of projections to maintain a realistic impression, using sensors and projectors to adapt to changes in shape and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real prototypes are produced to provide a realistic impression of apparel design, then the realism of design evaluation is improved, but the flexibility to modify design is worsened because it is difficult or impossible to modify them
Solution Approach 1:
The patent uses projection to create a visual copy of the design onto the physical prototype surface. Instead of modifying the physical prototype itself, the system projects colors, textures, patterns, and images onto it, allowing multiple design variations to be evaluated on the same physical base without any physical modification.
Solution Approach 2:
The system dynamically changes the projected design elements in real-time based on user input or design requirements. The projection can be updated instantly to show different colors, patterns, or textures, allowing the design appearance to be modified without changing the physical prototype structure.
2Adaptability or versatility
If computer-aided 3D modelling software is used to visually model design proposals, then the ease of modifying design is improved, but the realism of design evaluation is worsened because a computer screen can only provide an approximate impression
Solution Approach 1:
The system introduces a projection as an intermediary between the digital design model and the physical prototype. The projection acts as a mediator that transfers the virtual design elements onto the physical surface, combining the advantages of both digital flexibility and physical realism in a single evaluation experience.
3Measurement precision
If new physical 3D models are generated from scratch for each new design proposal, then the accuracy of design representation is improved, but the productivity is worsened due to the time-consuming process
Solution Approach 1:
The system performs preliminary action by creating a single physical prototype base that can serve multiple design evaluations. Instead of preparing new physical models for each design, the base prototype is prepared once and then used repeatedly with different projected designs, significantly reducing preparation time while maintaining evaluation accuracy.
