Solution Overview

Problem

Existing display devices cannot simultaneously process and display multiple images from different sources in response to a pointed location on the screen, limiting integrated control and coordination of images displayed in the same window or area.

Innovation Solution

A display device with a display unit showing multiple areas on a surface, a location detection unit to identify the pointed location, and a processing unit that executes operations across these areas, allowing for image processing such as drawing, superimposition, enlargement, or reduction based on the detected location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple images from different sources are displayed simultaneously in separate display areas, then the display device can show diverse content, but the device cannot execute integrated processing operations across all displayed images in response to a pointed location

Engineering Contradiction:

Improvecapability to display multiple imagesVSAvoidintegrated control of multiple images

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the control of multiple independently displayed images by introducing a processing unit that executes operations across all display areas simultaneously. When a location is detected on the display surface, the processing unit applies the same operation (e.g., enlargement, reduction, drawing) to all images regardless of which display area they occupy, thereby combining previously separate control functions into a unified system.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The processing unit is designed with universal functionality to handle multiple types of operations (enlargement, reduction, drawing, superimposition) across multiple display areas. This multi-functional capability allows a single unit to perform diverse processing tasks on multiple images, eliminating the need for separate control mechanisms for each image or display area.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If individual control of each displayed image is maintained, then each image can be independently manipulated, but collective processing operations cannot be executed across multiple images simultaneously

Engineering Contradiction:

Improveindependent image controlVSAvoidcollective processing efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent combines individual image control capabilities with collective processing by implementing a processing unit that can operate on multiple images simultaneously. The system maintains the ability to display and individually address images in separate areas while adding the capability to execute collective operations when a location is pointed, thereby merging independent and unified control modes.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The control system dynamically switches between individual and collective operation modes based on user input. When a location is detected on the display surface, the system activates collective processing mode to execute operations across multiple images simultaneously. The processing unit adapts its behavior based on the detected location and the type of operation required, enabling flexible switching between control modes.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If a pointer and trace display function is implemented for single image control, then user interaction is enhanced, but the function cannot be applied to multiple images displayed simultaneously

Engineering Contradiction:

Improveuser interaction capabilityVSAvoidapplicability to multiple images

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The processing unit is designed with universal functionality to execute pointer and trace display operations across multiple images simultaneously. When a location is detected, the unit can draw pointers, traces, circles, rectangles, or other graphical elements on any or all displayed images, making the interaction capability applicable to multi-image displays just as it is to single-image displays.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The display surface is segmented into multiple display areas, each capable of displaying different images, while the processing unit provides unified interaction control across all segments. The location detection unit identifies pointed locations on the overall display surface, and the processing unit applies operations to the appropriate display areas or images based on the detected location, maintaining seamless user interaction across segmented displays.

Inventive Principle:

Principle #1Segmentation
