Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing multi-function peripherals require users to separately scroll through priority and history lists of tasks, necessitating a selection of which list to view, which is inconvenient.

Innovation Solution

A control device and recording medium that integrate scrolling through both priority and history lists on a task selection screen, allowing simultaneous scrolling of preset and historical task items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If separate scrolling regions are provided for priority list and history list, then both lists can be displayed in parallel, but users must select which list to scroll through, reducing ease of operation

Engineering Contradiction:

Improvenumber of lists displayedVSAvoidease of scrolling through lists

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent merges the scrolling function into a single unified scrolling region where both the priority list and history list are displayed. A single scroll bar controls the scrolling of both lists simultaneously, eliminating the need for users to switch between separate scrolling regions. This combining approach maintains the ability to display both lists in parallel while significantly improving ease of operation.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If separate scroll bars are provided for priority list and history list, then each list can be scrolled independently, but the device complexity increases

Engineering Contradiction:

Improveindependent scrolling capabilityVSAvoidnumber of scroll bars

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple scroll bars into a single scroll bar that controls both the priority list and history list simultaneously. This single scroll bar is positioned to allow users to scroll through both lists in unison, reducing device complexity while maintaining the ability to view both lists. The merging approach eliminates redundant scrolling controls.

Inventive Principle:

Principle #5Merging (Combining)

3Quantity of substance

If fixed menu items and history menu items are displayed in separate regions, then both can be visible simultaneously, but user efficiency in selecting menu items decreases

Engineering Contradiction:

Improvenumber of menu items visibleVSAvoidmenu item selection efficiency

Core Design Contradiction:

Quantity of substanceVSProductivity

Solution Approach 1:

The patent merges the display regions of fixed menu items and history menu items into a single unified scrolling region. Both types of menu items are displayed together in parallel within this single region, allowing users to access and select from all available menu items without switching between separate display areas. This significantly improves menu item selection efficiency while maintaining visibility of multiple items.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A control device includes a processor that controls display of a task selection screen which is a task selection screen for selecting one task item from a plurality of task items and in which a priority list, which is a list of preset task items, and a history list, which includes histories of task items executed in the past, are displayed in parallel, in which the processor is configured to integrally scroll through the priority list and the history list in a case in which a scrolling operation has been performed for the priority list or the history list.
