Image Display Apparatus Network Band Congestion Management

Solution Overview

Problem

Image display apparatuses connected to multiple image transmitting apparatuses over a network face congestion issues due to simultaneous data transmission, leading to increased load on the CPU and delayed image display, as they can only accept data from one transmitting apparatus at a time.

Innovation Solution

An image display apparatus with a connected device controller that grants display authority to one image transmitting apparatus, allowing it to prioritize image data transmission, while others can only transmit with permission, managing network bandwidth and load conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the image display apparatus permits connection from multiple image transmitting apparatuses and allows each to freely transmit image data, then the adaptability is improved, but the network band congestion occurs and the CPU load increases

Engineering Contradiction:

Improveability to accept connections from multiple image transmitting apparatusesVSAvoidnetwork band congestion and CPU load

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent implements dynamic connection management where the image display apparatus selectively accepts or rejects connection requests from image transmitting apparatuses based on current system conditions. The connected device controller dynamically adjusts the number of active connections and prioritizes data transmission, allowing the system to adapt between handling multiple apparatuses versus maintaining optimal performance, thus resolving the contradiction between adaptability and resource consumption

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by controlling the state of connections - either accepting or rejecting connection requests from image transmitting apparatuses. By dynamically adjusting connection acceptance status and data transmission priorities, the system optimizes the balance between supporting multiple apparatuses and preventing network/CPU overload

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the image display apparatus accepts image data from multiple image transmitting apparatuses simultaneously, then the versatility is improved, but the time to process and display image data increases

Engineering Contradiction:

Improveability to receive image data from multiple apparatusesVSAvoidprocessing time and display delay

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements dynamic connection management where the image display apparatus selectively accepts or rejects connection requests from image transmitting apparatuses based on current system conditions. The connected device controller dynamically adjusts the number of active connections and prioritizes data transmission, allowing the system to adapt between handling multiple apparatuses versus maintaining optimal performance, thus resolving the contradiction between adaptability and resource consumption

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs preliminary assessment of connection requests before fully accepting them. The connected device controller evaluates whether to permit additional connections based on current load conditions, preventing excessive connections that would cause processing delays. This preliminary control mechanism ensures that versatility is maintained within acceptable performance boundaries

Inventive Principle:

Principle #10Preliminary action
