Solution Overview

Problem

Users face a fragmented experience when managing device groups across different device control systems, as they need to manually synchronize device group data separately in each application, leading to inconsistencies and inefficiencies.

Innovation Solution

A system that synchronizes device group data across multiple device control systems by identifying corresponding groups based on name and member similarity, merging them, and propagating modifications automatically, ensuring seamless control across different applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If device group data is managed separately in each device control application, then each application can independently control its devices, but users experience fragmented management and must manually synchronize data across applications

Engineering Contradiction:
Improvedevice group managementVSAvoidmanual synchronization time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent merges device group data from multiple device control applications into a unified data structure. The system identifies corresponding device groups across different applications based on name and member similarity, then consolidates them into a single synchronized group that can be managed from any application without manual intervention.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If device group data is managed separately in each application, then each application maintains its own data integrity, but inconsistencies arise across applications requiring manual updates

Engineering Contradiction:
Improvedata consistencyVSAvoidsynchronization mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements a feedback mechanism where device group data from multiple applications is continuously monitored and compared. When changes are detected in one application, the system automatically propagates these changes to other applications, ensuring data consistency through continuous feedback loops rather than complex manual synchronization.

Inventive Principle:
Principle #23Feedback

3Productivity

If manual synchronization is required across applications, then users have full control over data changes, but the process becomes inefficient and error-prone

Engineering Contradiction:
Improvedevice group management efficiencyVSAvoiddata entry process
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system enables self-service automation where device group data is automatically synchronized across applications without requiring user intervention. The system independently identifies corresponding groups, merges data, and propagates changes, freeing users from repetitive manual data entry while maintaining accuracy through automated validation rules.

Inventive Principle:
Principle #25Self-service

AI summary

Techniques for synchronizing device group data across different device control applications are described. A device group may include two or more smart home devices that may be controlled/supported by different device control applications. A user may set up device groups, including the same devices, in the different device control applications. A system may include a group synchronization service that synchronizes (e.g., merges) the multiple device groups across the different device control applications. The groups may be synchronized based on matching group names, matching devices included in the group, etc. After the device groups are synchronized, modifications made by the user to a device group in one device control application may be propagated to other device control applications.
