Extrapolating Tabular Structure in Freeform Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Freeform documents lack structural associations among elements, making creation and modification of tabular layouts tedious, as they do not enforce a predefined layout, and imposing a strict structure limits flexibility.
Innovation Solution
A method to extrapolate a tabular structure in freeform documents by determining a primary column and secondary columns, allowing for manipulation such as reordering, resizing, and inserting elements, while maintaining flexibility in layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a predefined structure such as table or grid is enforced, then structural association and manipulation ease are improved, but layout flexibility is worsened
Solution Approach 1:
The patent implements dynamic tabular structure extrapolation that adapts to different element arrangements. The system detects tabular patterns in freeform documents and dynamically creates corresponding table structures, allowing users to manipulate elements with tabular operations while maintaining layout flexibility. The structure is not fixed but dynamically generated based on the actual element arrangement in the document.
Solution Approach 2:
The patent introduces an intermediary layer between the freeform canvas and the tabular structure. This intermediary enables the system to translate between freeform element arrangements and tabular representations, allowing users to work in the flexible freeform environment while benefiting from structured manipulation capabilities through the detected and extrapolated table structures.
2Adaptability or versatility
If no predefined structure is enforced, then layout flexibility is improved, but structural association and manipulation ease are worsened
Solution Approach 1:
The patent performs preliminary detection of tabular patterns in the freeform document before manipulation operations are performed. By pre-identifying the tabular structure through element selection and relationship detection, the system prepares the structural information in advance, enabling easy manipulation operations to be applied subsequently without requiring the user to manually define structures.
Solution Approach 2:
The system performs self-service by automatically detecting and extrapolating tabular structures from the freeform element arrangements. Instead of requiring users to manually create table structures, the system autonomously analyzes the spatial relationships between elements, identifies tabular patterns, and generates appropriate table structures, thereby providing structured manipulation capabilities without user intervention in the structural definition process.

AI summary
Various embodiments of systems and methods for extrapolating tabular structure to facilitate manipulation of elements in the freeform document are described herein. The freeform document includes an unstructured canvas providing users the ability to place one or more elements in the canvas. A primary column is determined by the selection of at least one element in the freeform document. Further, one or more secondary columns in the freeform document corresponding to the primary column are determined. A tabular structure in the freeform document is extrapolated based on the determined primary column and the one or more secondary columns to facilitate manipulation of elements in the freeform document, such as reordering, resizing and deleting the one or more elements, and inserting one or more new elements in the freeform document.
