Solution Overview
Problem
Current 3D computerized geometric modeling systems lack methodologies and technologies to incorporate intelligence for assisting users in performing geometric design and other behaviors or design features, leading to inefficiencies in creating and modifying complex geometric models.
Innovation Solution
A CAD geometric modeling system that includes a connector building module, pairing module, and intelligent behavior module to add connectors, match components based on pairing rules, and invoke intelligent behaviors, such as geometric adjustments and constraint relationships, using a data store for component and rule information, enabling hierarchical structure-based pairing and intelligent operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional 3D geometric modeling systems are used, then basic geometric design functions are provided, but intelligence for assisting users is lacking
Solution Approach 1:
The system is divided into distinct functional modules: a pairing module that identifies and matches components based on geometric features, and an intelligent behavior module that applies design rules and constraints. This segmentation allows the system to add intelligence without requiring a complete system redesign, thereby improving adaptability while managing complexity.
Solution Approach 2:
The patent introduces pairing rules and intelligent behavior rules as intermediary elements that mediate between raw geometric data and design decisions. These rules act as knowledge intermediaries that enable intelligent assistance without directly increasing the core system's structural complexity.
2Productivity
If manual component matching and design operations are performed, then design control is maintained, but design efficiency is reduced
Solution Approach 1:
The system performs preliminary actions by automatically identifying components and their geometric features before the user needs to make design decisions. The pairing module pre-processes geometric data to extract features and potential matches, so when users interact with the system, the heavy lifting of component identification and matching has already been completed, significantly improving design efficiency.
Solution Approach 2:
The intelligent behavior module enables the system to serve itself by automatically applying pairing rules and design constraints without requiring manual user intervention for each design decision. The system self-manages the complex tasks of component matching and constraint application, freeing users to focus on higher-level design decisions.
3Manufacturing precision
If component pairing is performed without automated rules, then flexibility is maintained, but matching accuracy is reduced
Solution Approach 1:
The patent transforms the component matching problem from a subjective manual process to an objective rule-based process by changing the parameters used for matching. Instead of relying on user judgment, the system uses geometric parameters (dimensions, shapes, positions) and pairing rules to objectively determine matching accuracy, thereby improving precision while introducing a structured rule system.

AI summary
A computer-aided design (CAD) geometric modeling system, including a CAD software, a data store, a connector building module, a pairing module and an intelligent behavior module, all executable by at least one computing device. A user may use the CAD software to implement geometric models for multiple components. The data store stores necessary information of the system. The connector building module may add connectors on the components. The pairing module may identify a first component and at least one second component capable of matching the first component, and then identify connectors on the first and second components to match the first component to the second component by forming a matching pair of the identified connectors based on the pairing rules. The intelligent behavior module may receive the intelligent rules for the intelligent behaviors of the components of the matching pair, and invoke intelligent behaviors according to the intelligent rules.
