Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

As the number of input interfaces on display devices increases, users face difficulty in determining changes in input states, such as the start or stop of image information input, during preview displays, making it hard to manage and identify active and inactive interfaces.

Innovation Solution

A method for controlling display devices with multiple input interfaces, where identification images are displayed in corresponding areas, and priority-based determination is used to identify and update the display of image information input, ensuring clear visualization of active and inactive interfaces by updating the display accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of input interfaces is increased to provide more input options, then the adaptability and versatility of the display device is improved, but the ease of operation deteriorates because users cannot easily figure out changes in input state

Engineering Contradiction:

Improvenumber of input interfacesVSAvoidease of figuring out input state

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The display screen is segmented into multiple display areas, with each area corresponding to a specific input interface. Identification images are displayed in these segmented areas to visually indicate the input state of each interface, allowing users to easily track which interfaces are active without confusion.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different colors or visual states are used to indicate different input states. When image information is input to a specific interface, the identification image in the corresponding display area changes color or visual appearance, providing immediate visual feedback to users about the input state of each interface.

Inventive Principle:

Principle #32Color changes

2Adaptability or versatility

If the number of input interfaces is increased to provide more input options, then the adaptability and versatility of the display device is improved, but the device complexity increases making it harder to manage input states

Engineering Contradiction:

Improvenumber of input interfacesVSAvoidcomplexity of managing input states

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display device automatically manages the visualization of input states through the display control section, which automatically determines and updates identification images based on the current input state. This self-service mechanism eliminates the need for manual tracking by users, reducing the perceived complexity of managing multiple input interfaces.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system provides automatic visual feedback by displaying identification images that change according to the input state. The display control section continuously monitors input states and updates the display accordingly, providing real-time feedback to users about which interfaces are active, thereby simplifying the management of multiple input interfaces.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If identification images are displayed for all input interfaces, then the ease of operation is improved by making input states visible, but the area available for displaying actual image content is reduced

Engineering Contradiction:

Improvevisibility of input statesVSAvoiddisplay area for image content

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The display screen is divided into multiple display areas, with each area dedicated to showing identification images for specific input interfaces. This segmentation allows the display device to clearly indicate input states while organizing the information in a structured manner that minimizes space requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of displaying full preview images for all interfaces simultaneously, the system displays only identification images (a partial representation) to indicate input states. This partial action approach provides sufficient information for users to understand the input state without consuming excessive display area, reserving more space for the main image content.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A control method including home screen display step of making display section display a home screen where identification images representing the respective input interfaces are displayed in respective display areas so as to correspond one-to-one when image information is not input to N input interfaces provided to the display device, determination step of determining whether one of the input interfaces has changed to state in which the image information is input, identification step of identifying display area having the highest priority representing an order of displaying image out of the display areas where the identification images are currently displayed when the determination result is affirmative, and home screen information update step of displaying image input to input interface in display area thus identified, and displaying the identification images of the input interfaces in the state in which the image information is not input in the display areas lower in priority.
