Innovation Solution
An automated method and system that inputs customized parameters, recognizes parts using a design rule base, and utilizes CAD software to generate and manage customized engineering drawings, reducing the need for manual intervention by identifying standard and common parts and regenerating drawings as necessary, with features like file name management and version control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used for engineering drawing work in CAD software, then flexibility and customization are maintained, but productivity is reduced and time consumption increases
Solution Approach 1:
The system enables self-service by allowing the engineering drawing generation process to automatically identify customized parts, call CAD software, and complete drawing generation without manual intervention. The automated recognition process analyzes part files, determines customization needs based on design rules, and triggers CAD software execution automatically, eliminating the need for engineers to manually operate CAD software for each drawing task.
Solution Approach 2:
The system changes parameters by automatically detecting customized parameters from part files and using these parameters to drive the drawing generation process. The recognition process extracts parameter information from assembly files and part files, compares them against design rules, and uses the identified customized parameters to automatically generate appropriate engineering drawings without manual parameter input.
2Productivity
If automated recognition and generation is implemented, then productivity and speed are improved, but device complexity increases
Solution Approach 1:
The system segments the complex automated drawing generation process into distinct functional modules: a recognition process that identifies customized parts by analyzing part files and design rules, and a drawing generation process that calls CAD software to create engineering drawings. This segmentation allows each module to be independently developed, tested, and maintained, reducing overall system complexity while enabling automated operation.
Solution Approach 2:
The system introduces an intermediary recognition process that acts as a mediator between the part files and the CAD software. This recognition process analyzes part information, determines customization requirements based on design rules, and selectively triggers CAD software execution only for customized parts. This intermediary layer simplifies the overall system by automating the decision-making process and reducing direct complexity between file processing and drawing generation.
3Reliability
If all parts are processed for drawing generation, then completeness is ensured, but loss of time increases due to unnecessary processing of standard parts
Solution Approach 1:
The system applies partial action by processing only the necessary subset of parts for drawing generation. The recognition process analyzes each part file against design rules and identifies only those parts that are customized and require drawing updates. Standard parts that conform to existing designs are automatically excluded from the drawing generation process, ensuring that time is not wasted on unnecessary processing while still maintaining completeness for all customized parts.
Solution Approach 2:
The system extracts and separates customized parts from standard parts through the recognition process. By analyzing part files and comparing them against the design rule base, the system extracts only the customized parts that need drawing generation, leaving standard parts to be handled through existing processes. This extraction ensures that drawing generation is performed only where necessary, maintaining reliability while reducing time loss.
