Drawing Reference Number Mapping for Faster Patent Figure Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for analyzing knowledge information contents, such as patent documents, are inefficient due to the lack of a drawing-oriented content analysis method that links drawings and texts, making it difficult to quickly access relevant information.
Innovation Solution
A method and apparatus that utilize optical character recognition and machine learning to identify and replace drawing reference numbers with descriptions, allowing for drawing-centered analysis and intuitive information retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If OCR technology is used to recognize characters on knowledge information contents, then character recognition speed is improved, but the ability to quickly acquire information related to drawings is not achieved
Solution Approach 1:
The patent segments the content analysis by distinguishing between character recognition (OCR) and drawing reference number recognition. It extracts drawing reference numbers specifically from drawings and matches them with descriptions in text, creating a separate processing pathway for drawing-related information that complements general OCR capabilities.
Solution Approach 2:
The patent introduces drawing reference numbers as an intermediary element that links drawings and text. By recognizing and extracting these reference numbers from both drawings and text, the system creates a bridge that enables users to quickly access drawing-related information through text descriptions and vice versa.
2Ease of manufacture
If drawings and related texts are placed on different pages due to formatting limitations, then layout constraints are satisfied, but reading efficiency deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where drawing reference numbers in text are linked to corresponding drawings and vice versa. When users encounter a reference number during text reading, they can immediately access the related drawing without manually searching, and the system provides feedback by highlighting or navigating to the corresponding visual element.
Solution Approach 2:
The patent adds a dimensional link between text and drawings by embedding hyperlinks or cross-references that connect drawing reference numbers in text to actual drawings, and drawing reference numbers in images to their descriptions. This creates a navigational dimension that allows rapid movement between related content regardless of physical page location.
3Loss of information
If a drawing-oriented content analysis method is implemented, then drawing information accessibility is improved, but system complexity increases
Solution Approach 1:
The patent performs preliminary extraction and indexing of drawing reference numbers from both drawings and text during the content processing stage. By pre-identifying and storing the relationships between drawing reference numbers and their corresponding descriptions, the system eliminates the need for complex real-time analysis when users query drawing-related information.
Solution Approach 2:
The patent creates a simplified copy or representation of the drawing-content relationships through structured data storage. Instead of analyzing the full complexity of document structures during user queries, the system uses preprocessed index data that replicates the essential relationships, enabling fast retrieval without reprocessing the entire document hierarchy.

AI summary
A method for outputting a drawing reference number description including recognizing a size of a patent drawing and a position of a drawing reference number included in the patent drawing and acquiring a relative position coordinate of the drawing reference number in the patent drawing; setting a relative position coordinate of the drawing reference number description corresponding to the drawing reference number based on the acquired relative position coordinate; and outputting the drawing reference number description on the set relative position coordinate, thereby outputting such that the drawing reference number description corresponds to the drawing reference number.
