Fitness Machine Wireless Pairing via Unique ID Broadcast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for wirelessly pairing fitness machines with accessories using Bluetooth® are inefficient, particularly for devices without NFC readers, as they require manual selection of advertising packets and lack a streamlined process for connection establishment.
Innovation Solution
The system employs a setup module with a Bluetooth® module to communicate a unique ID from the accessory to the fitness machine, which broadcasts an advertising packet containing this ID, enabling automatic pairing without relying on NFC or the Out-of-Band (OOB) mechanism, thus simplifying the connection process and supporting a wider range of devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual selection of advertising packets is used for Bluetooth pairing, then devices can be paired, but the process requires significant time and effort from the user
Solution Approach 1:
The system performs preliminary actions by having the accessory device broadcast its unique ID before the fitness machine initiates the pairing process. The fitness machine automatically captures this pre-broadcasted ID, eliminating the need for manual selection during pairing.
Solution Approach 2:
The pairing process becomes self-service as the fitness machine automatically identifies and selects the accessory device based on the pre-broadcasted unique ID. No user intervention is required for device selection, as the system autonomously completes the pairing identification step.
2Ease of operation
If NFC readers are required for streamlined pairing, then connection establishment is simplified, but the system cannot support accessories without NFC readers
Solution Approach 1:
The system achieves universality by implementing a pairing method that works with both NFC-equipped and non-NFC devices. The unique ID broadcast mechanism serves as a universal identification method that replaces NFC-specific protocols, allowing broad device compatibility while maintaining streamlined pairing.
Solution Approach 2:
The patent substitutes the NFC mechanical/protocol system with a Bluetooth-based unique ID broadcast mechanism. This replacement eliminates the dependency on NFC hardware while achieving similar streamlined pairing functionality through wireless Bluetooth communication.
3Productivity
If automatic device selection is implemented, then pairing time is reduced, but the system becomes more complex in managing advertising packets and unique IDs
Solution Approach 1:
The system extracts the device identification function from the complex Bluetooth advertising packet selection process. By separating the unique ID broadcast as a distinct, simple signal before pairing, the system simplifies the overall complexity while maintaining automatic device selection capability.

AI summary
Systems and methods for wirelessly pairing a fitness machine to an accessory, the fitness machine having a setup module configured to communicate with the accessory using a setup protocol and having a Bluetooth® module configured to communicate with the accessory using a Bluetooth® protocol. The fitness machine is configured to receive a unique ID from the accessory using the setup protocol and the fitness machine is configured to wirelessly pair with the accessory using a Bluetooth® protocol. The systems and methods include an advertising packet configured to be communicated from the fitness machine to the accessory using the Bluetooth® protocol and the advertising packet includes the unique ID received from the accessory. The fitness machine is configured to wirelessly pair with the accessory when the accessory identifies the unique ID included in the advertising packet.
