Solution Overview

Problem

Users face difficulty in anticipating the type of list items that will be added when increasing the number of list items displayed on a UI, such as thumbnail images or icons, in response to user operations.

Innovation Solution

An information processing device with a display control unit that displays multiple lists, including a first list and a second list, where the second list is a sub-list of the first list, and performs display coupling of the second list to the first list in response to user operations, allowing users to preview the list items to be added.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the number of list items displayed on the UI is increased in response to user operation, then the user can check more details, but the user cannot know in advance what kind of list items are to be added

Engineering Contradiction:

Improvenumber of list itemsVSAvoidinformation about list items to be added

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The patent displays a sub-list containing list items that will be added to the main list in advance, before the user completes the operation to increase the number of list items. This preliminary display allows users to preview the content of list items to be added, resolving the information loss problem while maintaining the ability to increase list item quantity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent separates the displayed list into a main list and a sub-list, where the sub-list contains the list items that will be added. This segmentation allows the user to view the additional list items separately before they are integrated into the main list, providing advance information about what will be added

Inventive Principle:

Principle #1Segmentation
