Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic devices face high power consumption when transmitting and controlling frame information between devices, particularly when the variance in frame information is minimal, leading to inefficient energy use.

Innovation Solution

Implement a method where a first electronic device determines the variance of frame information transmitted to a second device and pauses or interrupts the transmission if the variance is within a predetermined range, allowing the second device to display stored frame information, thereby reducing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple pieces of frame information are transmitted continuously from the first electronic device to the second electronic device, then the display content is updated in real-time, but the power consumption increases significantly

Engineering Contradiction:

Improvereal-time display updateVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic transmission control by continuously monitoring frame variance between the first and second electronic devices. When variance exceeds a threshold, transmission is activated; when variance is within threshold, transmission is suspended. This dynamic adjustment of transmission state based on real-time conditions resolves the contradiction between maintaining real-time display updates and reducing power consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the transmission parameter from continuous to conditional based on frame variance. By introducing a variance threshold parameter and comparing actual frame differences against this parameter, the system selectively activates transmission only when necessary, thereby reducing overall power consumption while maintaining display freshness when content actually changes.

Inventive Principle:

Principle #35Parameter changes

2Use of energy by moving object

If frame information transmission is interrupted to save power, then power consumption is reduced, but the display content may become outdated

Engineering Contradiction:

Improvepower consumptionVSAvoiddisplay content freshness

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the second electronic device continuously monitors frame variance and compares received frames with local display content. This feedback loop ensures that transmission is only suspended when content is identical, and automatically resumes when changes are detected, thereby maintaining display content freshness while enabling power savings during static periods.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent performs preliminary comparison of frame content before deciding whether to transmit. By pre-evaluating whether frame variance exceeds the threshold, the system avoids unnecessary transmission activities, thereby reducing power consumption while ensuring that transmission is triggered in advance when content changes occur, maintaining display freshness.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If frame variance threshold is set low to ensure display freshness, then content updates are more frequent, but power consumption increases

Engineering Contradiction:

Improvedisplay content freshnessVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent optimizes the variance threshold parameter to balance between display freshness and power consumption. By carefully selecting an appropriate threshold value that reflects the minimum meaningful change, the system avoids excessive transmission triggers while still capturing significant content changes, thereby resolving the contradiction between frequent updates and power efficiency.

Inventive Principle:

Principle #35Parameter changes

4Use of energy by moving object

If frame variance threshold is set high to reduce power consumption, then transmission occurs less frequently, but display content may appear stale

Engineering Contradiction:

Improvepower consumptionVSAvoiddisplay content freshness

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent fine-tunes the variance threshold parameter to achieve optimal balance. By setting the threshold at a level that distinguishes meaningful content changes from minor variations, the system reduces unnecessary transmissions (saving power) while still triggering updates when content becomes stale, thereby resolving the contradiction between power savings and display freshness.

Inventive Principle:

Principle #35Parameter changes
