Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display screen magnification technologies are limited by software environment constraints, lack flexibility in magnification settings, and do not allow for universal application across devices, particularly in entertainment systems like TVs and game consoles, where users cannot easily select magnified positions or use hotkeys for quick switching.

Innovation Solution

A control method and system that generates a video signal and a control signal to process and magnify frames based on user input, allowing for flexible selection of magnification size and position using a cursor and hotkeys, enabling magnification at designated areas on the display screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If software display screen magnification function is used, then magnification control is achieved, but it is limited by software environment and cannot be applied to entertainment devices

Engineering Contradiction:

Improvedevice compatibilityVSAvoidsoftware environment dependency

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary processing layer between the video signal source and display device. The display device itself becomes the mediator that performs magnification processing, eliminating dependency on host software environment. The control signal from host system triggers the display device's internal processing circuit to execute magnification, making the function universally applicable across different devices including entertainment devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces software-based magnification control with a hardware-level processing solution. By implementing magnification functionality within the display device's processing circuit, it substitutes the software environment dependency with a hardware-capable system that can operate independently of the host's software capabilities.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If OSD menu interface is used for magnification, then physical button control is achieved, but magnification positions are limited to predefined locations

Engineering Contradiction:

Improvephysical button controlVSAvoidmagnification position flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent transforms the static, predefined magnification positions of OSD menus into dynamic, user-selectable positions. Through cursor control and hotkey input, users can dynamically specify any location on the screen for magnification. The system adapts to user needs by allowing arbitrary position selection rather than being constrained to fixed locations.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent makes the magnification function universal by allowing it to operate at any position on the display screen, not just predefined locations. The combination of cursor-based positioning and hotkey activation creates a multi-functional control system that adapts to various user needs and scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If OSD menu interface is used for magnification, then parameter adjustment is achieved, but hotkey switching and concurrent operations are not supported

Engineering Contradiction:

Improveparameter adjustment capabilityVSAvoidoperational efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent implements hotkey functionality that allows users to pre-configure and quickly switch between magnification parameters. Instead of navigating through menus during operation, users can set hotkeys in advance that trigger specific magnification settings instantaneously, enabling rapid switching and concurrent operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent enables continuous operation by allowing hotkey-based magnification control that does not interrupt other tasks. Users can activate magnification, adjust parameters, and switch settings without exiting current applications or workflows, maintaining continuous productive action across multiple operations.

Inventive Principle:

Principle #20Continuity of useful action
