Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing image display devices lack flexibility in frame position and shape adjustment, limiting the degree of freedom in image presentation and decoration.

Innovation Solution

A display method and device that acquires content information to display a second image along the outline of a first image when a first condition is met, and a third image with different color or pattern when a second condition is met, using an optical device controlled by a processor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed frame structure is used, then the device structure is simple, but the degree of freedom in image presentation and decoration is limited

Engineering Contradiction:

Improvedegree of freedom in image presentationVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses a projection device to project frame images onto the display surface, creating a virtual copy of the frame rather than using a physical frame structure. This allows multiple frame styles, positions, and shapes to be displayed without changing the physical device structure, thereby increasing adaptability while maintaining structural simplicity.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent enables dynamic adjustment of frame parameters including position, shape, and visual characteristics through software control. The frame can be dynamically repositioned, resized, and restyled based on different display conditions and user preferences, providing high adaptability without requiring complex mechanical adjustment mechanisms.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a single frame style is used, then the device structure is simple, but the ability to match different content genres is reduced

Engineering Contradiction:

Improveability to match content genreVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The projection device serves multiple functions: it can display different frame styles, patterns, and colors for different content genres (news, sports, entertainment, etc.). A single device structure achieves multi-functionality by projecting various frame images digitally, eliminating the need for multiple physical frame configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the visual parameters of the frame (color, pattern, thickness, style) through software control rather than physical changes. This allows the same device to adapt to different content genres by adjusting frame parameters dynamically, maintaining structural simplicity while achieving high adaptability.

Inventive Principle:

Principle #35Parameter changes

AI summary

A controller of a projector acquires tag information indicating a content of a content image; displays a decoration image disposed along an outline of the content image outside the content image when the tag information meets a first condition; and displays the decoration image disposed along the outline of the content image outside the content image and having a different color or pattern, when the tag information meets a second condition, which is different from the first condition.
