Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack an efficient method to regenerate structural networks, such as those found in dragonfly wings, using only boundary geometry without prior information on topology or geometry.
Innovation Solution
The use of a geometry-based equilibrium method known as graphic statics combined with machine learning techniques to relate the morphology of structural networks to static equilibrium, allowing for the regeneration of similar networks from boundary geometry.

Engineering Contradiction Analysis
1Measurement precision
If traditional structural design methods are used, then complete topological and geometric information is required, but this increases data requirements and computational complexity
Solution Approach 1:
The patent uses generative adversarial networks to create a virtual copy of the structural network based solely on boundary geometry. The GAN learns from training data to generate realistic structural patterns without requiring explicit topological information, effectively copying natural structural designs through machine learning rather than traditional geometric construction methods
Solution Approach 2:
The patent replaces traditional graphic statics and mechanical construction methods with machine learning-based generative models. Instead of using force diagrams and equilibrium equations to determine structural networks, the system uses neural networks trained on boundary geometry to directly generate structural patterns, substituting mechanical computation with statistical learning
2Manufacturing precision
If graphic statics and machine learning are combined, then structural network generation accuracy improves, but computational complexity increases
Solution Approach 1:
The patent divides the structural network generation into two distinct components handled by separate GAN modules: one network generates the topological structure (graph layout), while another generates geometric properties (node positions, edge thicknesses). This segmentation allows each sub-network to specialize in specific aspects, improving overall accuracy while managing computational complexity through modular architecture
Solution Approach 2:
The patent introduces an intermediate representation layer between boundary input and final structural output. The GAN first generates a simplified graph structure that captures topological relationships, then refines this into complete geometric details. This intermediate stage acts as a mediator that breaks down the complex transformation from boundary to full structural network into manageable steps

AI summary
A method for generating a structural form using a machine learning model includes receiving a definition of a boundary of a target structure. The method further includes generating an output force diagram using the boundary and one or more machine-learning models trained on at least one force diagram of an internal network of a natural structure. The method further includes generating a structural form within the boundary using the output force diagram.
