Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CAD systems face challenges in accurately and efficiently sharing and collaborating on specific 3D model components due to the need for manual navigation and outdated references, leading to errors and inefficiencies in communication among design engineers.
Innovation Solution
The implementation of a 3D-link mechanism that creates a static and variable link to target a 3D context within a CAD model, allowing for precise sharing and display of 3D locations, including geometric entities, and updating the link to maintain validity even if the model changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual navigation methods are used to locate 3D model components, then users can access model elements, but the process is time-consuming and error-prone
Solution Approach 1:
The system pre-generates 3D links that contain embedded navigation instructions and location data for specific model components. When a user clicks a 3D link, the navigation path is already prepared and executed automatically, eliminating the need for manual navigation steps and reducing time loss.
Solution Approach 2:
The patent introduces 3D links as an intermediary element between collaborators and 3D model components. These links act as mediators that automatically translate a collaborator's reference to a specific model location into precise navigation and display actions, eliminating manual navigation errors and提高效率.
2Adaptability or versatility
If static references to 3D model components are used, then sharing is simplified, but the references become outdated when models change
Solution Approach 1:
The patent implements dynamic 3D links that automatically update when the underlying 3D model changes. The system monitors model modifications and refreshes the link data accordingly, ensuring that references remain valid and accurate across different model versions without requiring manual intervention.
Solution Approach 2:
The system incorporates feedback mechanisms where the 3D link continuously monitors the state of the referenced model components. When changes are detected, the link receives feedback and automatically adjusts its reference data, ensuring ongoing reliability and accuracy of shared information.
3Measurement precision
If detailed 3D context information is shared, then collaboration accuracy improves, but the complexity of sharing mechanisms increases
Solution Approach 1:
The patent segments 3D context information into discrete, structured data elements within the 3D link (e.g., component identifiers, location coordinates, view parameters). This segmentation allows precise sharing of specific model aspects without requiring complex overall model transfers, maintaining accuracy while managing complexity through modular information organization.

AI summary
A computer-aided design (CAD) system and corresponding method enable users to manage and share information related to a three-dimensional (3D) context of a 3D CAD model with ease. The method creates a 3D-link targeting the 3D context. The 3D-link includes a static link and a variable link. The static link re-directs to the variable link in response to a user opening the 3D-link. The variable link enables (i) the 3D CAD model to be located and opened and (ii) the 3D context to be displayed within the 3D CAD model. The method stores the 3D-link in a database. The 3D-link enables the 3D context to be shared between or among users via sharing of the 3D-link from the database. The 3D-link plays an important role in helping design engineers collaborate by eliminating the need to create pictures or copies of 3D models that may become outdated.
