Solution Overview

Problem

Existing devices and services do not allow for seamless management and synchronization of user profiles across multiple devices and applications, requiring users to sign into separate accounts for each service and lacking options for users to opt into or out of sharing profile data.

Innovation Solution

A system that allows a customer account to have multiple user profiles, enabling users to opt into or out of sharing their profiles and profile data across devices, with profile enrollment managing which profiles are available on specific devices, and using APIs to update, add, or delete user profiles and synchronize data across devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate user accounts are required for each service on each device, then user privacy and security are maintained, but user profile management complexity increases and user convenience deteriorates

Engineering Contradiction:
Improveuser profile management convenienceVSAvoidaccount management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple user profiles under a single customer account, allowing users to manage multiple profiles (e.g., family members) from one account. This combines the functionality of multiple separate accounts into a unified structure, reducing the complexity of managing separate accounts for each service while maintaining the ability to distinguish between different users through profile-specific data and settings.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The customer account structure serves multiple functions: it authenticates users, manages multiple user profiles, stores shared data (like payment information), and controls data sharing permissions. This multi-functional account system replaces the need for separate accounts for each service, simplifying user profile management across different applications and devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If user profile data is synchronized across all devices, then user experience consistency is improved, but user control over data sharing is reduced

Engineering Contradiction:
Improveprofile data sharing flexibilityVSAvoiduser control over personal data
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system dynamically controls data sharing permissions, allowing users to adjust which profiles can access shared data at different times. The permission structure is not static but can be modified by the account holder to reflect changing user needs and preferences, enabling flexible control over data sharing while maintaining synchronization capabilities.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system provides feedback mechanisms that allow users to monitor and control which profiles are sharing data and with which devices. Users can review active data sharing permissions and modify them based on observed usage patterns, ensuring they maintain awareness and control over their personal data while benefiting from synchronized profile data.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If multiple user profiles are allowed per customer account, then personalization is enhanced, but system complexity increases

Engineering Contradiction:
Improveuser personalization capabilityVSAvoidprofile management system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments user identity into two distinct layers: the customer account (which manages permissions and shared data) and the user profiles (which contain personalized information). This segmentation allows multiple profiles to exist under one account without creating a monolithic complex structure, as each profile remains a discrete, manageable unit with clear boundaries and specific functions.

Inventive Principle:
Principle #1Segmentation

4Reliability

If profile enrollment controls are implemented for each device, then data security is improved, but ease of use deteriorates

Engineering Contradiction:
Improvedata sharing securityVSAvoiddevice setup simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system implements self-service mechanisms where the account holder automatically manages profile enrollment and data sharing permissions without requiring manual intervention for each device or profile. The system autonomously controls which profiles can access shared data based on the permissions set by the account holder, maintaining security while simplifying the user experience through automated enforcement of access rules.

Inventive Principle:
Principle #25Self-service

AI summary

Devices, systems, and methods are provided for user profile management across multiple devices. A method may include determining, by a first device, that the first device is signed into a customer account; determining that the customer account includes a first user profile and a second user profile, the first user profile having first identity data, and the second user profile having second identity data; determining that third identity data for the first user profile is available for presentation, the third identity data based on a user interaction with a second device; determining that the first user profile is enrolled on the first device; presenting the first identity data using the first device; receiving a second user request to access the first user profile; and presenting, using the first device, content based on the second user request and a user preference associated with the first user profile.
