Electronic Document Visible Object Attribute Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When converting electronic documents from one format to another, existing technologies often discard attributes of visible objects, leading to inconsistencies when the document is reconverted back to its original format, affecting user experience.
Innovation Solution
A method that extracts and embeds attributes of visible objects into metadata during the conversion process, allowing for the restoration of the original format when converting back, using a system with an extractor, conversion engine, and embedding engine to manage electronic documents across different formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electronic document is converted from the first format to the second format using existing conversion technologies, then the conversion process is simple and fast, but the attributes of visible objects are discarded or lost during conversion
Solution Approach 1:
The patent extracts attributes of visible objects from the original electronic document before conversion occurs. This preliminary extraction ensures that the attributes are preserved and can be used during subsequent conversion processes to maintain object consistency across format changes.
Solution Approach 2:
The patent introduces an intermediary mechanism that transfers attributes from the original document format to the converted document format. This intermediary process involves extracting attributes in the first format, converting them to the second format, and applying them during the conversion, thereby preventing attribute loss without significantly impacting conversion speed.
2Adaptability or versatility
If the electronic document is converted back to the original format, then the format restoration is achieved, but the visible objects do not appear the same as before conversion due to lost attributes
Solution Approach 1:
The patent implements a feedback mechanism where attributes extracted from the original document are applied during conversion and then used to verify and restore the original appearance. When converting back to the first format, the system retrieves the previously extracted attributes and applies them to ensure visible objects render identically to their original state, thereby maintaining reliability across multiple conversion cycles.
Solution Approach 2:
The patent transforms attributes from the first format to the second format and back again, maintaining the essential characteristics of visible objects through parameter transformation. This allows the document to be converted between formats while preserving the visual appearance and properties of objects by systematically managing attribute parameters throughout the conversion process.
3Loss of information
If the attributes are extracted and embedded into metadata during conversion, then the original attributes are preserved for restoration, but the conversion process becomes more complex
Solution Approach 1:
The patent divides the conversion process into distinct segments: attribute extraction, attribute conversion, document conversion, and attribute application. This segmentation allows each step to be handled independently and systematically, managing complexity by breaking down the overall process into manageable components that can be executed in sequence.
Solution Approach 2:
The patent extracts attributes from the original electronic document as a separate, independent step before performing the main conversion. This extraction process isolates the attribute handling from the document conversion, allowing attributes to be preserved and managed separately, thereby reducing the complexity of the overall conversion process while ensuring attribute preservation.

AI summary
A method involves managing electronic documents (EDs). The method includes receiving a first request to convert an original ED including a visible object from a first format to a second format; extracting, in response to the first request, multiple attributes in the original ED specifying the visible object and required to restore the visible object in the first format; generating, by converting the original ED from the first format to the second format, a converted ED including rendering data of the visible object that is grammatically native to the second format and that is necessary to render the visible object from the second format; and embedding the attributes extracted from the original ED into metadata of the converted ED.
