Solution Overview

Problem

Existing electronic musical instrument displays often fail to clearly show necessary information by simultaneously switching between user performance operations and performance-assisting information, leading to confusion and missed essential data.

Innovation Solution

A display device with a processor that prioritizes the display of information based on set categories, ensuring that performance-assisting information is shown preferentially over user performance operations, using a hierarchical priority order to prevent simultaneous display of multiple information types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the display displays multiple pieces of information simultaneously, then the quantity of information displayed increases, but the clarity and ease of detecting essential information deteriorates

Engineering Contradiction:

Improvequantity of information displayedVSAvoiddifficulty of detecting essential information

Core Design Contradiction:

Quantity of substanceVSDifficulty of detecting and measuring

Solution Approach 1:

The display divides information into distinct segments (performance operation information and performance-assisting information) and displays them separately rather than simultaneously. This segmentation allows the display to show one type of information at a time, improving detectability while maintaining comprehensive information coverage through sequential display.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by displaying performance operation information first, then subsequently displays performance-assisting information. This sequential approach ensures that essential information is detected in a structured manner, with the display preparing to show different types of information in priority order rather than attempting to show all information at once.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If the display switches between different types of information, then the versatility of information display increases, but the stability of information presentation deteriorates

Engineering Contradiction:

Improveversatility of information displayVSAvoidstability of information presentation

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The display dynamically adapts its behavior based on the type of information being displayed. When performance operation information is detected, the display shows it with specific characteristics, and when performance-assisting information is detected, it switches to different display characteristics. This dynamic adaptation maintains stability within each information type while providing versatility across different information types.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs preliminary identification of information type before displaying it. By detecting whether the information is performance operation-related or performance-assisting-related in advance, the display can stabilize its presentation characteristics for each type while maintaining the ability to switch between types as needed.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the display shows performance operation information, then the relevance to user actions increases, but the importance of performance-assisting information decreases

Engineering Contradiction:

Improverelevance to user actionsVSAvoidloss of performance-assisting information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The display segments information into performance operation information and performance-assisting information, displaying each type separately in dedicated time slots. This ensures that performance-assisting information is not lost or overshadowed by performance operation information, as both types receive equal display attention through sequential presentation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system maintains continuity of useful action by ensuring that both performance operation information and performance-assisting information are displayed in sequence without interruption. The display continuously provides relevant information to the user, switching between types to ensure comprehensive information delivery rather than focusing on one type exclusively.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A display device includes a display and a processor. The display displays one piece of a plurality of pieces of information and does not display two or more pieces of the plurality of pieces of information simultaneously. The processor causes the display to preferentially display a second piece of information included in the plurality of pieces of information rather than a first piece of information included in the plurality of pieces of information in accordance with a set priority order. The first piece of information corresponds to a performance operation of a user, and the second piece of information assists a performance of the user.
