Reverse Wireless Discovery for IoT Ecosystem Onboarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adding a new IoT device to a user's ecosystem require direct wireless connections, which can be disruptive, costly, and confusing for users, especially when the new device needs to enter Bluetooth pairing or soft-AP mode, and may require manual interaction with WiFi settings.
Innovation Solution
The new IoT device discovers the user's mobile device through existing IoT devices in the ecosystem, using framework-specific WiFi signaling to receive the mobile device's MAC address and communicate indirectly through an existing IoT device as a proxy, eliminating the need for direct connections and manual user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct wireless connection is used for device discovery, then connection reliability is improved, but user confusion and operational complexity increase
Solution Approach 1:
The patent introduces an existing IoT device as an intermediary to facilitate discovery between the new device and mobile device. The existing device receives discovery information from the new device and forwards it to the mobile device, eliminating the need for direct wireless connection during discovery. This resolves the contradiction by maintaining reliable communication through the intermediary while avoiding user confusion associated with direct pairing modes.
2Adaptability or versatility
If Bluetooth pairing mode or soft-AP mode is required for discovery, then device compatibility is improved, but device complexity and cost increase
Solution Approach 1:
The patent makes the existing IoT device serve multiple functions: it acts as both a regular IoT device and as a discovery intermediary. By reusing the existing device's wireless communication capabilities for proxying discovery information, the system achieves universal compatibility without requiring the new device to implement specialized Bluetooth or soft-AP functionality, thereby reducing device complexity.
3Measurement precision
If manual interaction with WiFi settings is required, then connection accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent enables the new IoT device to autonomously perform discovery by broadcasting its information and receiving responses through the existing device, without requiring manual user interaction with WiFi settings. The system self-services the discovery process by leveraging the existing device's established connection to the access point, thereby maintaining connection accuracy while dramatically improving ease of operation.

AI summary
A method and system to facilitate adding a new IoT device to an IoT ecosystem that includes an existing IoT device, where a mobile device is configured to control the IoT ecosystem. In an example, the new device detects a wireless broadcast from the existing device that provides identification information of the mobile device. In response, the new device then uses the provided identification information of the mobile device as a basis to scan for and discover wireless presence of the mobile device. And responsive to the discovering wireless presence of the mobile device based on the mobile-phone identification information provided by the existing device, the new device then transmits to the mobile device, via the existing device as a wireless proxy, new-device information about the new device - which enables the mobile device to prompt for and obtain user approval to add the new device to the IoT ecosystem.
