Solution Overview

Problem

Shared electronic devices in workplaces and homes require frequent personalization or multiple accounts to accommodate different users, leading to inefficiencies and security concerns.

Innovation Solution

A communications system that includes an electronic device and a personal information token with WPAN devices, allowing the token to wirelessly transmit subscription keys and personal preferences to the device for automatic network subscription and personalized settings, and to unsubscribe when out of proximity, ensuring secure and convenient use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple accounts are created for different users, then each user can have personalized settings, but the device complexity and security management become more difficult

Engineering Contradiction:

Improvepersonalized settingsVSAvoidaccount management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the personalization data into separate segments: subscription keys stored in the token device and personalized lists stored in the electronic device. This segmentation allows each user to have their own isolated data segments without affecting other users, resolving the contradiction by enabling personalization while keeping account management simple through physical separation of user identifiers and preferences.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The token device acts as an intermediary that carries subscription keys and facilitates automatic authentication. Instead of managing multiple accounts directly in the electronic device, the token serves as a mediator that provides user identification information, simplifying the account management process while maintaining personalized settings for multiple users.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If manual personalization is performed for each user, then personalized settings can be achieved, but the time and effort required increases significantly

Engineering Contradiction:

Improvepersonalized settingsVSAvoidpersonalization time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-storing subscription keys in the token device and pre-configuring personalized lists in the electronic device. When a user approaches the device, the system automatically retrieves and applies their pre-stored preferences without requiring manual input at the moment of use, thereby eliminating personalization time while maintaining personalized settings.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables self-service personalization where the electronic device automatically detects the token, retrieves the subscription key, and applies the corresponding personalized list without user intervention. The device serves itself by automatically switching between different user profiles based on the detected token, eliminating the time users would otherwise spend on manual personalization.

Inventive Principle:

Principle #25Self-service

3Productivity

If shared devices are used by multiple individuals, then space and cost are saved, but security concerns and personalization challenges arise

Engineering Contradiction:

Improveresource efficiencyVSAvoidsecurity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies local quality by providing different security levels and personalization data to different users through their respective tokens. Each user's token contains their specific subscription key, and the electronic device applies the corresponding personalized list locally for that user. This ensures that each user experiences a personalized and secure environment while sharing the same physical device, resolving the contradiction between resource efficiency and security.

Inventive Principle:

Principle #3Local quality

4Adaptability or versatility

If separate accounts are created for each user, then personal preferences can be stored, but the ease of operation decreases due to account switching requirements

Engineering Contradiction:

Improvepersonal preferences storageVSAvoidaccount switching

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system implements self-service account switching where the electronic device automatically detects the user's token and switches to the appropriate account and personalized list without requiring manual user action. The device autonomously manages account transitions based on the presence of different tokens, maintaining the ability to store multiple personal preferences while eliminating the operational burden of manual account switching.

Inventive Principle:

Principle #25Self-service

AI summary

A communications system includes an electronic device a first wireless personal area network (WPAN) device, and a first processor coupled to the first WPAN device. The communications system also includes a personal information token with a second processor and a second WPAN device coupled thereto. The second processor is configured to store at least one subscription key, and wirelessly transmit the at least one subscription key to the electronic device based upon proximity therewith, via the second WPAN device. The first processor, via the cellular device, then subscribes the electronic device to the cellular network based upon the subscription key.
