Solution Overview
Problem
Existing learning models struggle with accurately and creatively completing missing parameter data due to oversimplification of parameter complexity and misjudgment of interrelatedness, leading to inaccurate and constrained outputs, especially in complex datasets.

1Extent of automation
If a learning model is used to impute missing parameter data, then the system can automatically complete partial parameters, but the output accuracy decreases due to oversimplification of parameter complexity and misjudgment of parameter interrelatedness
Solution Approach 1:
The patent transforms the parameter completion problem from a direct imputation task into a multi-dimensional space by constructing an assembly graph that represents parameters as nodes and their relationships as edges. This graph structure adds a dimensional layer that captures complex interdependencies, allowing the model to navigate parameter relationships through graph embeddings and cross-attention mechanisms rather than direct linear prediction.
Solution Approach 2:
The patent introduces several intermediary components: (1) assembly graph as an intermediary structure to represent parameter relationships, (2) graph embedding as an intermediary representation to capture structural information, (3) cross-attention model as an intermediary mechanism to integrate graph embeddings with parameter predictions. These intermediaries enable the model to handle complex parameter interdependencies without directly modeling all relationships explicitly.
2Productivity
If a learning model imputes missing data, then the system can generate completed parameters, but design diversity is limited and creativity is reduced
Solution Approach 1:
The patent implements a feedback mechanism where the cross-attention model continuously refines parameter predictions by attending to relevant graph embeddings and previously predicted parameters. This iterative attention-based refinement allows the system to explore multiple plausible parameter configurations, enhancing design diversity while maintaining completion efficiency through the structured guidance of the assembly graph.
3Extent of automation
If traditional learning models are used for parameter completion, then the system operates passively, but collaborative features and design alternatives are lacking
Solution Approach 1:
The patent transforms the static parameter imputation process into a dynamic, iterative refinement process. The cross-attention mechanism dynamically adjusts which graph nodes and parameters to focus on based on current prediction needs, allowing the system to adaptively explore design alternatives and provide collaborative design support rather than simply filling in missing values.
