Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for displaying function keys on TVs, such as printing icons on the shell, are difficult to modify and can lead to incorrect operation if icons are misplaced.

Innovation Solution

A system and method that acquires the screen display area size and preset key function icons, determines their display positions based on size and mode, and monitors key triggers to display icons accurately on the screen, improving key operation precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If function icons are printed on the TV shell, then the icons are fixed and durable, but they cannot be modified and may be misplaced

Engineering Contradiction:

Improveicon positioning accuracyVSAvoidicon position modification capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent transitions from static printed icons to dynamic on-screen display icons that can be programmatically positioned and modified. The icon display positions are determined by a position determining module that can adjust locations based on different scenarios, resolving the contradiction between fixed reliability and modification flexibility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent creates a virtual copy of the physical key icons on the screen display. These digital copies can be precisely positioned through software control and modified without physical changes, achieving both accurate positioning and easy modification capability.

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If icons are displayed on screen, then they can be modified easily, but they may not be accurately aligned with physical keys

Engineering Contradiction:

Improveicon position modification capabilityVSAvoidicon-key alignment precision

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent implements a feedback mechanism where the display control module receives triggering states from physical keys and dynamically adjusts icon display positions on screen. This closed-loop control ensures accurate alignment between physical keys and their corresponding icons, resolving the precision concern while maintaining modification flexibility.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The position determining module pre-calculates and determines the optimal display positions of icons before they are shown on screen. This preliminary positioning ensures accurate alignment with physical keys from the start, preventing misalignment issues while allowing future modifications.

Inventive Principle:

Principle #10Preliminary action
