Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Digital signage systems face challenges in appropriately displaying messages due to varying message transmission frequencies, leading to either under-displaying when the frequency is low or empty spaces when it's high, as they cannot operate like user-terminal devices to adapt display methods.

Innovation Solution

A display apparatus with a message retrieval unit, a display method selection unit, and a display controller that switches between scrolling display methods based on the message count, selecting a first method for low counts and a second method for high counts to optimize message display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a simple display apparatus is used that cannot be operated by users, then the device complexity is reduced and ease of operation is improved, but the adaptability to adjust display methods based on message count is lost

Engineering Contradiction:

Improveuser operationVSAvoiddisplay method adaptation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The display apparatus automatically determines the appropriate display method by itself based on the message count, without requiring user operation or input. The system self-adjusts between first and second display methods according to the retrieved message count comparing it to a threshold value, making the apparatus self-sufficient in adapting to different message volumes.

Inventive Principle:

Principle #25Self-service

2Device complexity

If a fixed display method is used for all message counts, then the device complexity is reduced, but the display effectiveness deteriorates when message count varies

Engineering Contradiction:

Improvedisplay control mechanismVSAvoidmessage display effectiveness

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The display apparatus dynamically switches between a first display method and a second display method based on the message count. When the message count is below a threshold, the first display method is used; when it exceeds the threshold, the second display method is applied. This dynamic adjustment optimizes display effectiveness for varying message volumes without requiring complex manual configuration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the display parameter (display method) based on the message count parameter. By comparing the message count to a predetermined threshold, the system automatically selects appropriate display parameters to ensure effective message presentation, whether that means using the first display method for lower counts or the second method for higher counts.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If message transmission frequency is low, then the data processing load is reduced, but the display coverage and information completeness deteriorate

Engineering Contradiction:

Improvemessage processing speedVSAvoidmessage display coverage

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The display apparatus dynamically adjusts its display method based on the message count retrieved from the server. When the message count is below a threshold value, the first display method is applied to ensure comprehensive display coverage and information completeness. When the message count exceeds the threshold, the system switches to the second display method to maintain effective presentation under high-volume conditions.

Inventive Principle:

Principle #15Dynamics

4Quantity of substance

If message transmission frequency is high, then the information completeness is improved, but the display quality deteriorates due to empty spaces and inappropriate formatting

Engineering Contradiction:

AI summary

A display apparatus including a display that displays messages includes a message retrieval unit that retrieves messages by accessing a message management server, a display method selection unit that selects a display method for the retrieved messages in response to a count of the retrieved messages, and a display controller that performs control to display on the display the messages retrieved from the message management server in the display method selected by the display method selection unit. The display method selection unit selects a first display method that displays the retrieved messages while scrolling the retrieved messages repeatedly if the count of the retrieved messages is equal to or below a display switching threshold value, and selects a second display method that displays the retrieved messages while scrolling the retrieved messages if the count of the retrieved messages is above the display switching threshold value.
