Solution Overview

Problem

Users currently have to manually input strength calculation data into AutoCAD drawing tools, which is time-consuming and prone to errors, as they need to check and transfer data piece by piece from strength calculation programs.

Innovation Solution

A method and device for automatically generating AutoCAD drawings of heat exchangers by preprocessing strength calculation data to extract necessary information, converting it into a usable format, and loading it to generate drawings through an interactive interface that includes shape and thermal data visualization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If users manually input strength calculation data into AutoCAD drawing tools, then drawings can be generated, but the process is time-consuming and prone to errors

Engineering Contradiction:

Improvedrawing accuracyVSAvoiddrawing generation time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent uses optical character recognition (OCR) technology to automatically copy and recognize data from strength calculation result images, converting them into structured data that can be directly used for AutoCAD drawing generation, eliminating manual data entry

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces an intermediate processing system that includes an image processing unit, data extraction unit, and data structure generation unit.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If users manually check and transfer data piece by piece from strength calculation programs, then data accuracy can be verified, but the process becomes complex and time-consuming

Engineering Contradiction:

Improvedata accuracyVSAvoidprocess complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary data processing by automatically extracting, validating, and structuring data from strength calculation results before drawing generation. The system pre-processes the data to ensure accuracy and compatibility, reducing the need for manual verification during the drawing process

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the manual mechanical process of checking and transferring data with an automated computer-based system that uses OCR, image processing, and data structure generation algorithms to handle data extraction and validation

AI summary

A method of automatically generating AutoCAD drawings includes: generating a data sheet by using only input data which is necessary for generating drawings of a heat exchanger and obtained from strength calculation data provided by a strength calculation program; loading the data sheet by a loading unit; and generating AutoCAD drawings of the heat exchanger by activating an automatic AutoCAD drawing generation interface by a user's selection, the automatic AutoCAD drawing generation interface being activatable only after the data sheet may be loaded, wherein the input data includes both machine data and thermal data.
