Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wearable devices face challenges in maintaining pairing relationships when transitioning from an old companion device to a new one, as the backup process does not always allow for seamless pairing on the new device.

Innovation Solution

The technique involves syncing and verifying a migration key between the wearable and the new companion device, establishing a secured and encrypted communication channel to migrate settings and pairing data, allowing the wearable to validate trust and move its pairings without user intervention, such as scanning codes or entering PINs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a backup is restored to a new companion device, then data can be recovered, but the pairing relationship between wearable and companion device cannot be maintained

Engineering Contradiction:

Improvepairing relationship maintenanceVSAvoiddevice replacement capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary actions by syncing and verifying a migration key between the wearable device and the new companion device before completing the pairing migration. This ensures that the pairing relationship can be maintained when transitioning to a new device, resolving the contradiction between reliability of pairing maintenance and adaptability to device replacement.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The migration key acts as an intermediary element that enables the wearable device to validate trust with a new companion device. This intermediary mechanism allows the pairing relationship to be transferred seamlessly from an old device to a new device, maintaining reliability while enabling device replacement.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional pairing validation is required, then security is maintained, but user convenience and migration speed are reduced

Engineering Contradiction:

Improvesecurity validationVSAvoidpairing process simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system implements self-service by enabling the wearable device to automatically validate trust with the new companion device using the pre-synced migration key. This eliminates the need for manual user validation steps such as scanning codes or entering PINs, thereby maintaining security while significantly improving ease of operation and migration speed.

Inventive Principle:

Principle #25Self-service

AI summary

Migration of a pairing of wearable device to a new companion electronic device is disclosed. In one embodiment, pairing migration is performed by syncing and verifying a migration key in the wearable and new companion device. Pairing migration includes moving settings and pairing data of the wearable to the new companion device in response to detecting the wearable is associated with the migration key, wherein the migration key establishes a validation of trust of the wearable relative to the companion device. The settings and pairing data can include configuration and protected data and one or more keys to establish a trust relationship between the wearable and new companion device. The settings and pairing data can also include device data such that the wearable can be discoverable by the new companion device.
