Solution Overview

Problem

Current wireless display streaming technologies, such as Miracast, struggle with efficiently managing and configuring multiple display devices for seamless content presentation, particularly in dynamic environments where devices are added or removed.

Innovation Solution

The implementation of a system that includes a discovery component to identify available sink devices and display devices, a configuration component to group and bind devices for optimal content presentation, and a streaming component to communicate display streams wirelessly, using standards like IEEE 802.11 and Wi-Fi Display Standards, while monitoring for changes in device connectivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless display streaming technologies communicate digital video scene captures between two devices (source and sink), then real-time video transmission is achieved, but the system cannot efficiently manage and configure multiple display devices simultaneously

Engineering Contradiction:

Improvecapability to manage multiple display devicesVSAvoidsystem configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the display stream communication by introducing address tuples that identify specific sink devices and display devices within groups. This allows the system to divide and manage multiple display devices through structured addressing, enabling versatile multi-device management without proportionally increasing configuration complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a universal configuration framework that handles both single-device and multi-device scenarios through the same discovery, configuration, and streaming components. The system universally manages display devices whether they are individual units or grouped configurations, reducing the need for separate management protocols.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If the system groups and binds display devices for optimal content presentation, then seamless content presentation across multiple devices is achieved, but the configuration and monitoring processes become more complex

Engineering Contradiction:

Improveseamless content presentationVSAvoidconfiguration and monitoring complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by discovering and configuring display devices before actual content streaming begins. The discovery component identifies available devices, and the configuration component establishes groupings and bindings in advance, ensuring reliable seamless presentation while managing complexity through upfront setup rather than real-time adjustments.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where the system monitors for additions or removals of display devices and dynamically adjusts configurations. This feedback loop maintains reliable content presentation across dynamic device environments by automatically adapting to configuration changes without requiring manual reconfiguration.

Inventive Principle:

Principle #23Feedback

3Duration of action of stationary object

If the system dynamically adjusts configurations when devices are added or removed, then uninterrupted content presentation is maintained, but the discovery and configuration operations require additional processing

Engineering Contradiction:

Improvecontinuous content presentation durationVSAvoidtime for discovery and configuration operations

Core Design Contradiction:

Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The patent maintains continuity of useful action by implementing monitoring components that continuously track display device status without interrupting content streaming. When devices are added or removed, the system dynamically adjusts configurations in the background, ensuring uninterrupted content presentation while minimizing the time impact of discovery and reconfiguration operations.

Inventive Principle:

Principle #20Continuity of useful action
