Solution Overview

Problem

Existing electronic chalkboard systems face challenges in providing a convenient user experience due to the complexity of identifying and interacting with multiple display panels, as the menu and image adjustment options are often not easily accessible when using a pointing device to navigate a large screen formed by multiple display panels.

Innovation Solution

The system employs a pointing device that calculates coordinate information and transmits it to an image processor, allowing the display of images and menus on specific panels, with the option to dynamically relocate menus to adjacent panels for improved accessibility, ensuring that the user can easily adjust image characteristics across the large screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple display panels are arranged to form a large screen, then the display area is increased, but the complexity of identifying and interacting with specific panels increases

Engineering Contradiction:
Improvedisplay areaVSAvoidpanel identification complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The large display area is segmented into multiple independent display panels, each with its own identifier. The controller detects touch coordinates and determines which specific panel is touched, allowing independent control and display of different content on each panel, thus managing the complexity of large screen interaction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A controller acts as an intermediary between the pointing device and the multiple display panels. The controller receives touch input, calculates coordinates, identifies the touched panel using stored identifier information, and directs display output to the appropriate panel, simplifying the user's interaction with the multi-panel system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If menu options are displayed on the same panel as the image, then the interface is integrated, but the menu may interfere with the touch points and reduce accessibility

Engineering Contradiction:
Improvemenu accessibilityVSAvoidmenu interference with touch points
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The menu display is moved from the same panel dimension as the image to a different panel. When a user touches an image on one display panel, the controller displays the corresponding menu on a different display panel, separating the menu interface from the content area and eliminating interference between menu options and touch interaction points.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Measurement precision

If the pointing device must precisely identify touched panel coordinates, then the interaction precision is improved, but the operation complexity increases

Engineering Contradiction:
Improvetouch coordinate precisionVSAvoidoperation simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The pointing device automatically performs coordinate calculation and panel identification without requiring manual intervention. When the pointing device touches a display panel, the controller automatically calculates the coordinates, identifies the touched panel using stored identifier information, and displays the corresponding image and menu, making the precise operation transparent to the user.

Inventive Principle:
Principle #25Self-service

AI summary

An electronic chalkboard system including a plurality of display panels, a pointing device which touches the plurality of panels, an image processor which processes an image to be displayed on one of the plurality of panels that is drawn by the pointing device touching the one of the plurality of panels; a controller which selects one of the plurality of panels according to a preset condition based on a first panel of the plurality of panels if the first panel is touched by the pointing device, and controls the image processor to display on the selected panel a menu related to the image displayed on the first panel, and wherein, if a second panel of the plurality of panels is touched by the pointing device while the menu is displayed on the selected panel, the controller newly selects one of the plurality of panels according to the preset condition based on the second panel and transfers the displayed menu to the newly-selected panel.
