Event Relation Diagram Folding and Expansion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of events increases, it becomes difficult to find the event of interest in a relation diagram expressing logical relationships between them.
Innovation Solution
An information processing apparatus that displays a relation diagram from an upstream side to a downstream side, allowing for folding and expanding of events selected as starting points, enabling the user to manage and visualize the relationships effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of events in the relation diagram increases, then the comprehensiveness of the diagram increases, but the difficulty of finding the event of interest increases
Solution Approach 1:
The relation diagram is segmented into multiple collapsible groups or sections. Each group can be independently expanded or collapsed, allowing users to divide the large diagram into manageable portions and focus on specific areas of interest without being overwhelmed by the entire diagram.
Solution Approach 2:
The relation diagram implements dynamic expandable and collapsible structures. Users can interactively expand specific sections to view detailed events and relationships, or collapse them to reduce visual complexity and focus on higher-level overview, making the diagram adaptable to different viewing needs.
2Loss of information
If all events are displayed in the relation diagram, then the completeness of information is improved, but the usability and clarity of the diagram deteriorates
Solution Approach 1:
The diagram provides dynamic visibility control where all events are preserved in the data structure but selectively displayed through expand/collapse functionality. This maintains complete information availability while allowing users to control what is visually presented at any given time, balancing completeness with clarity.
Solution Approach 2:
Events are organized into segmented groups that can be independently controlled. Users can collapse groups to hide detailed events when not needed, or expand them to reveal complete information, thus managing the balance between information completeness and visual clarity through selective segmentation.
3Difficulty of detecting and measuring
If the relation diagram is expanded to show all details, then the detail visibility is improved, but the overall structure becomes harder to comprehend
Solution Approach 1:
The diagram allows users to dynamically adjust the level of detail displayed by expanding or collapsing sections. When viewing the overall structure, users can collapse sections to maintain simplicity; when examining specific areas, users can expand to reveal details, thus adaptively managing the trade-off between detail visibility and structural comprehensibility.
Solution Approach 2:
The diagram uses hierarchical grouping to add a dimensional layer of organization. Events are arranged in nested structures where the parent group represents a higher-level concept and child events provide detailed information. This hierarchical dimension allows users to comprehend the overall structure at the parent level while accessing detailed information at the child level when needed.

AI summary
An information processing apparatus includes a display control section that displays a relation diagram expressing logical relationships between events from an upstream side to a downstream side, displays, in a case where an instruction of folding is performed on a plurality of events selected as folding starting points from among the events, the relation diagram in which events on the downstream side of the plurality of selected events are folded, and displays, in a case where an instruction of expanding is performed on the relation diagram in a folded state, the relation diagram expanded in a state before the folding.
