Solution Overview

Problem

Current wireless presentation systems lack screen mirroring transmitters capable of supporting multiple virtual displays, limiting the ability of a single transmitter to pair with more than one receiver.

Innovation Solution

A wireless screen mirroring system comprising a first and second transmitting device, a first and second receiving device, and a router that functions as a controller or bridge, which pairs designated devices based on a configuration file to enable simultaneous audiovisual data transmission to multiple receivers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a screen mirroring transmitter supports only one virtual display, then the device complexity is reduced, but the adaptability is limited

Engineering Contradiction:
ImproveAbility to pair with multiple receiversVSAvoidTransmitter configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a router as an intermediary device that manages the pairing between transmitters and receivers. The router stores configuration files containing pairing relationships and controls the connection establishment, allowing a single transmitter to work with multiple receivers without increasing the transmitter's internal complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates virtual display copies through the router's configuration system. The router maintains configuration files that represent different pairing scenarios, enabling the transmitter to virtually connect with multiple receivers by selecting appropriate configuration entries rather than physically maintaining multiple simultaneous connections

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If multiple transmitters and receivers are connected simultaneously, then the versatility is improved, but the network load increases

Engineering Contradiction:
ImproveSystem configuration flexibilityVSAvoidNetwork bandwidth consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent implements periodic action through operational mode switching, where the system alternates between different transmission configurations. The router controls which transmitter-receiver pairs are active at any given time based on configuration files, enabling multiple devices to be connected in the system while only activating specific pairs when needed, thus reducing overall network load

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts its operational state by switching between different pairing configurations managed by the router. The router reads configuration files to determine optimal pairing arrangements, allowing the system to adaptively allocate network resources and minimize bandwidth consumption while maintaining versatility

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If manual pairing configuration is required for each device组合, then the measurement precision of device matching is improved, but the ease of operation deteriorates

Engineering Contradiction:
ImproveDevice pairing accuracyVSAvoidPairing setup convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent applies preliminary action by pre-configuring pairing relationships in configuration files stored on the router before actual device connection. The configuration files contain predetermined transmitter-receiver pairings, allowing the system to automatically establish connections based on these pre-planned configurations rather than requiring manual real-time setup, thus maintaining pairing accuracy while improving operational ease

Inventive Principle:
Principle #10Preliminary action

AI summary

A wireless screen mirroring system is provided. The wireless screen mirroring system includes a first transmitting device and a second transmitting device, a first receiving device and a second receiving device, and a router. The router has at least one of the functions of a controller or a bridge. The router selects one of the first transmitting device and the second transmitting device as a designated transmitting device, and selects at least one of the first receiving device and the second receiving device as a designated receiving device based on a configuration file. The router pairs the designated transmitting device with the at least one designated receiving device. After pairing is completed, the designated transmitting device displays audiovisual data, transmits the audiovisual data to the at least one designated receiving device, and the at least one designated receiving device displays the audiovisual data.
