CAD Regular Element Generation via Dynamic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of creating regular elements in computer-aided design (CAD) drawings, such as structural members, is time-consuming and tedious, requiring discrete drawing for each element and frequent re-entry of inputs for modifications.
Innovation Solution
A method for generating regular elements interactively and dynamically in real-time, allowing CAD designers to preview and modify the elements using a graphical user interface, with automatic real-time updates based on user inputs, such as the CTRL key, to control the number and arrangement of elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If regular elements are drawn one at a time using discrete drawing process, then each structural member can be precisely positioned, but the process becomes time-consuming and tedious
Solution Approach 1:
The patent segments the drawing process into two distinct modes: a dialog mode for bulk generation of regular elements and a direct mode for individual precise placement. This segmentation allows users to choose the appropriate method based on whether they need speed (dialog mode with automatic positioning) or precision (direct mode with manual control), thereby resolving the contradiction between positioning precision and drawing speed.
Solution Approach 2:
The patent implements dynamic switching between two operational modes (dialog mode and direct mode) that adapts to the user's needs. The system dynamically adjusts its behavior based on the selected mode: in dialog mode, it automatically generates multiple elements with precise positioning; in direct mode, it allows manual placement for precise control. This dynamic adaptability resolves the contradiction by providing both speed and precision depending on the operational context.
2Productivity
If dialog mode is used to automate generation of regular elements, then drawing speed increases, but user interaction becomes less flexible and requires re-entering inputs for modifications
Solution Approach 1:
The patent implements dynamic mode switching that allows users to transition between dialog mode (for speed) and direct mode (for flexibility) at any point during the drawing process. When users need to modify elements, they can switch to direct mode to make precise adjustments, then return to dialog mode to continue bulk generation. This dynamic adaptability resolves the contradiction by allowing users to leverage both speed and flexibility as needed.
Solution Approach 2:
The system allows users to self-manage the balance between automation and control by enabling free switching between modes. Users can initiate bulk generation for speed, then independently intervene by switching to direct mode for modifications, and resume dialog mode when ready to continue. This self-service approach resolves the contradiction by empowering users to control the degree of automation based on their immediate needs.
3Ease of operation
If manual drawing process is used for each structural member, then user control and precision are maintained, but the process becomes tedious and time-consuming
Solution Approach 1:
The patent segments the operational workflow into dialog mode for automated bulk generation (reducing time loss) and direct mode for manual precise control (maintaining user control). Users can segment their drawing tasks by using dialog mode for groups of regular elements where precision follows standard patterns, and switch to direct mode only when exceptional control is needed. This segmentation resolves the contradiction by minimizing time loss while preserving user control where necessary.
Solution Approach 2:
The patent applies partial automation through dialog mode for routine elements, freeing users from repetitive manual drawing for standard structural members. Users perform partial manual control only when needed by switching to direct mode, rather than manually controlling every single element. This partial action approach resolves the contradiction by eliminating time loss for routine tasks while maintaining user control for exceptional cases.

AI summary
The process of generating regular elements in a CAD drawing is accelerated by providing a CAD designer with graphical user interface (GUI) tools to generate regular elements for a CAD drawing interactively, dynamically, and in real-time. The GUI tools allow the CAD designer to preview the regular elements that he or she will be adding to the CAD drawing and modify the number of regular elements to be added interactively and in real-time.
