Solution Overview

Problem

Existing technologies lack a flexible and scalable method for dynamically grouping devices to provide coordinated content output, such as audio or video, across multiple devices, which limits user experience and efficiency in managing device interactions.

Innovation Solution

A session-based approach that dynamically groups devices based on a function, using a session identifier and session data to manage device membership and state, allowing for real-time updates and seamless transitions between devices for content output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If devices are grouped using traditional static methods, then device management is simple, but the system lacks flexibility and scalability for dynamic content output coordination

Engineering Contradiction:

Improveflexibility and scalability of device groupingVSAvoidcomplexity of device management system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic device grouping where devices are automatically added to or removed from groups based on their real-time state and session requirements. The system transitions from static predefined groups to dynamic session-based groups that adapt to changing conditions, allowing devices to join or leave content output groups as needed without manual reconfiguration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent segments the device management system into independent session modules, where each session represents a discrete content output task. This segmentation allows the system to manage multiple device groups simultaneously for different sessions, improving scalability and flexibility while keeping individual session management simple and isolated.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If devices are dynamically added or removed from groups, then system flexibility improves, but latency and transition smoothness deteriorate

Engineering Contradiction:

Improveability to add or remove devices dynamicallyVSAvoidlatency during device transitions

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-establishing session templates and device capability profiles before actual content output sessions begin. When devices need to be added or removed, the system can quickly match them against pre-defined session requirements and capability profiles, reducing the time needed for dynamic group adjustments and transitions.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If session data is maintained across application transfers, then user experience consistency improves, but system resource consumption increases

Engineering Contradiction:

Improveconsistency of user experience during application transfersVSAvoidsystem resource consumption for session maintenance

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements a session data copying mechanism where essential session information is replicated and stored in a centralized location accessible by multiple applications. Instead of maintaining full session state in every application, the system creates lightweight copies of critical session data, reducing overall memory consumption while ensuring consistency across application transfers through shared access to the session identifier and core parameters.

Inventive Principle:

Principle #26Copying

AI summary

Techniques for session-based device grouping are described. In an example, a computer system receives first data requesting an output, determines a function to provide content data based at least in part on the first data, determines a session identifier of a session associated with execution of the function, and determines session data associated with the session identifier. The session data includes a first device identifier of a first device, an indication that the first device is outputting the content data, and a second device identifier of a second device. The computer system also causes, based at least in part on the session data including the second device identifier, the second device to output the content data.
