Solution Overview
Problem
Existing IoT devices require manual, one-by-one configuration and grouping, which is time-consuming and complex, especially when heterogeneous devices from different manufacturers are involved.
Innovation Solution
A method using a short countdown timer triggered by power supply to automatically initiate pairing and logical grouping of IoT devices, allowing them to form an ad hoc wireless network with a shared secret, simplifying the configuration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual one-by-one configuration method is used for IoT devices, then each device can be properly configured and associated with wireless network, but the time and complexity of device registration increases significantly
Solution Approach 1:
The system performs preliminary actions by automatically starting a counter when power is applied to the IoT device, preparing the device for automatic pairing before user interaction is needed. This preliminary counter initialization enables the device to be ready for discovery and association immediately upon power-up, eliminating manual configuration steps.
Solution Approach 2:
The IoT device performs self-service by automatically determining whether to perform pairing operations based on its own counter state without requiring manual user intervention. The device autonomously manages its own association with the wireless network by monitoring the counter and initiating pairing when conditions are met, thereby reducing registration time while maintaining configuration reliability.
2Adaptability or versatility
If manual configuration method is used for heterogeneous IoT devices from different manufacturers, then each device type can be managed with its specific protocol, but the complexity of managing multiple management systems increases
Solution Approach 1:
The system implements a universal management approach where a single counter mechanism and automatic pairing process works across heterogeneous IoT devices from different manufacturers. The counter-based discovery method provides a unified interface that abstracts away the underlying protocol differences, allowing diverse devices to be managed through a common procedure rather than requiring separate management systems for each device type.
Solution Approach 2:
The counter acts as an intermediary mechanism that mediates between power supply and the pairing decision for heterogeneous devices. This intermediate counter state provides a standardized way to trigger pairing operations across different device types, simplifying the management complexity while maintaining adaptability to various device protocols through the unified counter-based approach.
3Productivity
If automatic counter-based pairing is implemented, then device registration time and complexity is reduced, but the need for precise timing and counter state management increases device internal complexity
Solution Approach 1:
The system merges the counter management functionality directly into the existing power supply and pairing logic of the IoT device. Rather than adding a separate complex timing management system, the counter is integrated with the power-on sequence and pairing determination, combining multiple functions into a unified flow that increases registration speed without significantly increasing internal device complexity.

AI summary
A method for associating an Internet-of-Things (IoT) device with a wireless network, a method for discovering and logically grouping smart light bulbs, and a smart light bulb. One embodiment may comprise automatically starting a counter on an IoT device in response to initially receiving power from a power supply loop to which the IoT device is connected, and by the IoT device, determining whether to perform a pairing operation for associating the IoT device with a wireless network based at least in part on a state of the counter in the IoT device.
