Solution Overview

Problem

Image display devices experience discontinuity issues when sharing images due to unstable communication states and high memory usage during multi-tasking, especially when receiving high-resolution images unnecessarily.

Innovation Solution

An image display device with a wireless communication unit and controller that adjusts the channel condition based on the size of the image displayed, bandwidth, and execution state, allowing for dynamic resolution changes to minimize discontinuity and optimize memory usage by reducing unnecessary high-resolution image reception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the image display device receives high-resolution images to maintain image quality, then image quality is improved, but memory usage increases and causes discontinuity during multi-tasking

Engineering Contradiction:
Improveimage qualityVSAvoidmemory usage
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent implements dynamic resolution adjustment where the image display device changes the resolution of received images based on its current operating state (single-tasking vs. multi-tasking). When in multi-tasking mode, the device automatically reduces image resolution to lower memory consumption, while maintaining high resolution during single-tasking mode to preserve image quality.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the resolution parameter of received images according to the device's task state. The controller monitors whether the device is in single-tasking or multi-tasking mode and adjusts the image resolution parameter accordingly, transforming the fixed high-resolution reception into a variable parameter that adapts to system conditions.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the image display device maintains high channel condition for stable communication, then communication stability is improved, but image discontinuity occurs when channel condition changes during image transmission

Engineering Contradiction:
Improvecommunication stabilityVSAvoidimage continuity
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by having the controller proactively detect changes in channel condition during image transmission and preemptively adjust image resolution before discontinuity occurs. This advance detection and adjustment prevents image disruption rather than reacting after the problem occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a feedback mechanism where the controller continuously monitors channel condition and uses this information to adjust image resolution in real-time. When channel condition deteriorates, the system feedback loop triggers resolution reduction to maintain stable image reception, creating a closed-loop control system.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If the image display device receives images at original resolution to maintain fidelity, then image fidelity is improved, but communication load increases causing instability

Engineering Contradiction:
Improveimage fidelityVSAvoidcommunication load
Core Design Contradiction:
Manufacturing precisionVSLoss of energy

Solution Approach 1:

The patent dynamically changes the image resolution parameter based on communication conditions and device state. During stable single-tasking operation, high resolution maintains fidelity, while during multi-tasking or poor channel conditions, resolution is reduced to lower communication load, achieving adaptive optimization.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system transitions from static high-resolution reception to dynamic resolution adjustment. The image resolution adapts in real-time based on communication stability and device workload, allowing the system to optimize between fidelity and communication efficiency under different operating conditions.

Inventive Principle:
Principle #15Dynamics
