IoT Feature Exposure via Event Topics and Handler Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT devices face challenges in managing structured and unstructured data in real-time scenarios while providing an intuitive and maintainable architecture that allows easy extension of functionality, especially for novice users, and overcoming firewall issues to enable remote control.
Innovation Solution
An IoT device uses a definition file to map subscription event topics and event handlers, allowing it to subscribe to relevant topics via a message bus environment, generate a unique ID for secure communication, and expose features through a GUI, enabling secure and scalable control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a subscribe/publish architecture with multiple event listeners is used for IoT device control, then the device can handle various events flexibly, but the architecture becomes complex and difficult to maintain for novice users
Solution Approach 1:
The patent introduces an event manager as an intermediary component that sits between the event sources and multiple event listeners. This event manager centralizes the subscription logic and event routing, simplifying the architecture by eliminating the need for individual listeners to directly manage subscriptions. Novice users interact with a simplified interface while the event manager handles the complexity of multiple subscriptions and event routing internally.
2Productivity
If multiple event listeners are implemented for real-time data handling, then real-time scenario processing capability is improved, but the difficulty of managing structured and unstructured data increases
Solution Approach 1:
The patent segments the event handling process into distinct components: event subscription management, event routing, and event processing. Each event listener is assigned specific event types through the event manager, which organizes and structures the data flow. This segmentation allows real-time processing of both structured and unstructured data while reducing management complexity through clear separation of concerns and standardized data handling interfaces.
3Ease of operation
If a standardized event subscription approach is used, then ease of extension for novice users is improved, but the ability to handle complex event routing scenarios may be limited
Solution Approach 1:
The event manager is designed as a universal component that provides multiple functions: subscription management, event routing, filtering, and dispatching to multiple listeners. It offers a standardized interface for novice users to subscribe to events while internally handling complex routing scenarios through configurable event types and listener mappings. This multi-functionality allows the same component to serve both simple and complex event handling needs.
Data Source
AI summary
Methods, systems, and computer readable media for exposing features of an internet of things (IoT) device are disclosed. One example method for exposing features of an IoT device occurs at an IoT device. The method comprises: concurrently with or after bootup of the IoT device, accessing a definition file comprising one or more entries, wherein each of the one or more entries indicates a subscription event topic and an event handler for handling events associated with the subscription event topic; subscribing, via a message bus environment, to a first subscription event topic indicated by the definition file: receiving a first event message associated with the first subscription event topic; and processing, using a first event handler associated with the first subscription event topic indicated by the definition file, the first event message.
