Solution Overview

Problem

Existing display systems cannot divide and display image data from multiple input sources, such as different application programs, on a projection screen due to the projector recognizing the streaming device as a single input source.

Innovation Solution

A display system comprising an image processing device and a display device that can acquire and process image data from multiple application programs, allowing simultaneous side-by-side display of images from these sources, using wired and wireless communication paths and image processing to generate combined image data for display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the projector recognizes the streaming device as a single input source, then the system structure remains simple, but the image data from multiple application programs cannot be divided and displayed on the projection screen

Engineering Contradiction:

Improveability to display multiple images from different application programsVSAvoidsystem complexity for handling multiple input sources

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the image data processing by separating the acquisition of image data from different application programs (first acquirer, second acquirer) and processing them through distinct pathways (image processing device, display device) before combining them for display. This segmentation allows multiple images to be handled independently while maintaining system manageability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an image processing device as an intermediary component between the streaming device and the display device. This intermediary processes and combines image data from multiple application programs, enabling the display of multiple images without requiring the streaming device itself to become more complex.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If image data from multiple application programs is acquired and processed separately, then multiple images can be displayed side by side, but the processing time and computational resources increase

Engineering Contradiction:

Improvemulti-source image display capabilityVSAvoidprocessing time for acquiring and combining multiple image data streams

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by having the image processing device acquire and buffer image data from different application programs before the actual display operation. The first acquirer and second acquirer continuously gather image data, preparing it in advance for combination and display, which reduces processing delays during the actual rendering.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent ensures continuous operation by maintaining continuous acquisition of image data from multiple application programs through the image processing device. The system keeps all image data streams active and ready for combination, eliminating interruptions and waiting periods that would occur with sequential processing.

Inventive Principle:

Principle #20Continuity of useful action

3Adaptability or versatility

If the system displays images from multiple application programs simultaneously, then the display versatility improves, but the device complexity for coordinating multiple communicators and data streams increases

Engineering Contradiction:

Improvedisplay of multiple images from different sourcesVSAvoidcomplexity of coordinating communicators and data streams

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the coordination functions by centralizing the image processing device that handles all data streams from different communicators (first communicator, second communicator). Instead of each communicator managing its own data independently, the image processing device consolidates and coordinates all image data acquisition and processing, simplifying the overall system architecture.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The image processing device serves multiple functions: it acts as a data collector from different application programs, a coordinator of multiple communicators, a processor of image data streams, and a preparer for display output. This multi-functionality reduces the need for separate dedicated components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)
