Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current processes for designing articles intended for the human body, such as clothing and jewelry, are time-consuming, inefficient, and non-intuitive, often requiring multiple iterations and using conventional tools that are difficult for beginners to use, leading to a reliance on 'one-size-fits-all' designs.
Innovation Solution
A computer-implemented method that detects skin-based contacts and inputs on a body part to modify a virtual model, allowing for direct, generative, or parametric manipulation of 3D geometries, enabling efficient and intuitive design of articles tailored to individual body shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional mouse and keyboard input devices are used for generating and modifying 3D geometries, then the design process can be completed, but the process becomes non-intuitive and especially difficult for beginner users
Solution Approach 1:
The patent replaces conventional mechanical input devices (mouse and keyboard) with a touchscreen display that allows direct tactile interaction with the 3D virtual model. Users can touch, drag, and manipulate 3D geometries directly on the display surface, substituting complex mechanical tool operations with intuitive touch-based gestures.
Solution Approach 2:
The touchscreen display serves as an intermediary between the user and the 3D modeling system. It provides a visual interface where users can see and directly manipulate 3D geometries through touch gestures, bridging the gap between simple user input and complex 3D modeling operations.
2Manufacturing precision
If multiple iterations of complex 3D geometry modeling are performed to achieve precise fit, then the article can be customized, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system performs preliminary actions by automatically generating 3D geometries based on initial user input or body scanning data. The 3D model is pre-configured with parametric controls that allow direct adjustment of fit parameters, eliminating the need for multiple iterative fabrication and fitting cycles.
Solution Approach 2:
The 3D geometry modeling system employs dynamic parametric controls that allow real-time adjustment of geometric parameters. Users can directly modify 3D model parameters through touchscreen interactions, and the system dynamically updates the model and associated manufacturing data, enabling rapid customization without time-consuming iterations.
3Adaptability or versatility
If custom-made articles are designed for individuals, then precise fit is achieved, but the process becomes impractical due to time and resource constraints
Solution Approach 1:
The system uses parametric modeling where 3D geometries are defined by adjustable parameters. Users can directly modify parameters such as size, shape, and fit characteristics through touchscreen input, and the system automatically updates the 3D model and generates corresponding manufacturing data, enabling rapid customization.
Solution Approach 2:
The touchscreen-based 3D modeling system serves multiple functions: it allows body scanning or data input, real-time 3D model visualization, direct geometric manipulation, parameter adjustment, and manufacturing data generation. This multi-functional approach consolidates multiple design steps into a single intuitive interface, making custom design practical and efficient.

AI summary
A design engine for designing an article to be worn on a human body part (input canvas) in a virtual environment. A virtual model engine of the design engine is used to generate and modify a virtual model of the input canvas and a virtual model of the article based on skin-based gesture inputs detected by an input processing engine. The gesture inputs comprise contacts between an input tool and the input canvas at locations on the input canvas. The virtual model engine may implement different design modes for receiving and processing gesture inputs for designing the article, including direct manipulation, generative manipulation, and parametric manipulation modes. In all three modes, a resulting virtual model of the article is based on physical geometries of at least part of the input canvas. The resulting virtual model of the article is exportable to a fabrication device for physical fabrication of the article.
