Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If three-dimensional views are used to provide comprehensive construction information, then information completeness is improved, but software complexity increases
Solution Approach 1:
The patent combines three-dimensional model data with two-dimensional drawing data (including gridlines and dimensioning information) into a unified software application. This merging allows the system to provide comprehensive construction information from multiple sources simultaneously, resolving the contradiction by integrating rather than separately managing the complexity of handling both 3D and 2D information formats.
Solution Approach 2:
The software application is designed to perform multiple functions: displaying three-dimensional models, generating two-dimensional views, extracting gridline information, providing dimensioning data, and locating physical elements. This multi-functional approach consolidates various tools into a single universal platform, improving information completeness while managing software complexity through integrated design.
2Measurement precision
If multiple two-dimensional drawings are used to represent multi-floor construction projects, then information accuracy is improved, but time efficiency deteriorates
Solution Approach 1:
The patent utilizes the vertical dimension in three-dimensional space to organize and display multiple floor levels simultaneously. Instead of requiring separate two-dimensional drawings for each floor, the system stacks floor plans vertically in a single three-dimensional view, allowing users to navigate between floors using the vertical axis. This dimensional approach maintains the accuracy of individual floor representations while eliminating the time loss associated with switching between multiple separate drawings.
3Adaptability or versatility
If manual calculations are performed to locate physical elements, then flexibility is improved, but error rate increases
Solution Approach 1:
The software application provides self-service functionality by automatically calculating and displaying the locations of physical elements within the construction project. The system uses the integrated three-dimensional model and two-dimensional gridline data to perform measurements and locate elements without requiring manual calculations by users. This automation maintains the flexibility of locating any element while eliminating human calculation errors, directly resolving the contradiction between flexibility and error rate.
Data Source
AI summary
A computing device is configured to obtain gridline information for a three-dimensional drawing file and generate a two-dimensional view of the three-dimensional drawing file that includes (1) at least one gridline corresponding to the obtained gridline information, (2) at least one intersection between two meshes, and (3) initial dimensioning information involving (a) the at least one gridline and (b) at least one of the two meshes. Based on a user request to adjust a perspective of the two-dimensional view, the computing device adjusts the perspective of the two-dimensional view and thereby generates an updated two-dimensional view that includes updated dimensioning information corresponding to one or more meshes displayed in the updated two-dimensional view.
