Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D modeling tools require high precision and detail, making it difficult to translate 2D sketches into 3D models, and existing solutions do not effectively combine rapid shape exploration with precise 3D geometry construction.
Innovation Solution
A 3D modeling workflow system that allows users to create multiple 2D planes in a 3D scene, enabling the combination of painting and geometry construction, where users can switch between painting and geometry operations to sketch and create 3D models by using conventional tools like a mouse or stylus, with planes that can be arbitrarily positioned and oriented.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional 3D modeling tools are used, then manufacturing precision is improved, but ease of operation deteriorates because it is difficult to translate 2D sketches into 3D models
Solution Approach 1:
The patent merges 2D sketching operations and 3D geometry construction into a single unified environment. Users can create 2D planes, paint on them, and convert to 3D geometry all within the same interface, eliminating the need to switch between separate 2D and 3D modeling tools and thus resolving the contradiction between precision and ease of operation.
Solution Approach 2:
The patent introduces 2D planes as intermediary elements that serve as a bridge between 2D sketches and 3D geometry. These planes can be positioned and oriented arbitrarily in 3D space, allowing users to sketch on them and then convert the 2D artwork into 3D models, facilitating the translation process while maintaining precision.
2Ease of operation
If 2D sketching is used, then ease of operation is improved for rapid shape exploration, but manufacturing precision deteriorates
Solution Approach 1:
The patent enables dynamic switching between 2D sketching mode and 3D geometry construction mode. Users can start with fluid 2D painting for rapid shape exploration and then convert to precise 3D geometry when needed, allowing the workflow to adapt between creativity and precision requirements.
Solution Approach 2:
The patent allows users to work in 2D on arbitrarily positioned and oriented planes, then transition to 3D geometry construction. This dimensional transition enables users to explore shapes freely in 2D while achieving precise 3D results, resolving the contradiction between ease of operation and manufacturing precision.
3Adaptability or versatility
If multiple 2D planes are created in 3D space, then adaptability is improved for combining painting and geometry, but device complexity increases
Solution Approach 1:
The patent creates a universal 3D modeling environment that supports multiple functions: creating 2D planes, painting on them, constructing 3D geometry, and converting between 2D and 3D representations. This multi-functional capability provides hybrid workflow adaptability while managing system complexity through a unified interface.

AI summary
A 3D modeling workflow system is disclosed that allows the user to create multiple 2D planes or paint canvases in the 3D scene each having a position and orientation. These 2D planes can be arbitrarily positioned in the 3D scene and can contain a combination of paint and model construction geometry. The construction geometry can span multiple 2D planes. The user is allowed to sketch on the planes using paint and create curve geometry in and between the planes using the sketches as a reference. Collectively the 2D planes allow a 3D object to be represented with different types of input where portions of the object are drawn in by paint and other or the same portions are composed of geometry. The user can swap between painting on the 2D planes and creating model geometry as needed.
