Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shared electronic devices in communal settings face challenges in personalization and account management, requiring frequent re-personalization or separate accounts, which can be inconvenient and insecure.
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 personalized settings to the device for secure and convenient subscription to cellular networks, as well as automatic display of personalized lists and account management based on proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate accounts are created for each individual in shared electronic devices, then personalization is improved, but device complexity increases
Solution Approach 1:
The patent segments personalization data into two distinct components: subscription keys stored securely in the SIM card and personalized lists stored in the device memory. This segmentation allows the system to manage multiple user accounts without increasing overall complexity, as each user's data is divided into these two manageable parts that can be independently handled.
Solution Approach 2:
The patent introduces personalized lists as an intermediary layer between the user and the electronic device's core functionality. These lists act as a mediator that enables personalization without requiring direct modification of device settings or creation of separate system accounts, thereby simplifying account management while maintaining adaptability.
2Adaptability or versatility
If re-personalization is performed each time an individual uses the device, then personalization is improved, but loss of time increases
Solution Approach 1:
The patent applies preliminary action by pre-storing personalized lists in the device memory during the initial setup or previous usage sessions. When a user returns to the device, the system automatically detects the user's presence and retrieves the pre-stored personalized lists, eliminating the need for time-consuming re-personalization processes each time the device is used.
Solution Approach 2:
The system implements self-service by automatically detecting user presence through the SIM card and retrieving the corresponding personalized lists from memory without requiring manual user input or intervention. This automatic retrieval process eliminates the time loss associated with manual re-personalization while maintaining accurate personalization for each user.
3Ease of operation
If subscription keys are stored in the SIM card for automatic device subscription, then ease of operation is improved, but security risks increase due to potential unauthorized access
Solution Approach 1:
The patent segments authentication data into subscription keys stored in the SIM card and personalized lists stored in the device. This segmentation ensures that even if the SIM card is accessed unauthorized, the personalized lists remain protected in the device, and vice versa, thereby maintaining security while enabling automatic subscription functionality.
Solution Approach 2:
The patent applies local quality by storing different types of data in different locations with different security characteristics. Subscription keys are stored in the SIM card which has its own security mechanisms, while personalized lists are stored in the device memory with device-level security. This localized storage strategy optimizes both ease of operation for automatic subscription and security against unauthorized access.

AI summary
A communications system 110 includes an electronic device 112 having a first wireless personal area network (WPAN) device 120 , and a first processor coupled 116 to the first WPAN device. The communications system also includes a personal information token 130 with a second processor 134 and a second WPAN device 138 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 a cellular device 119 , then subscribes the electronic device to the cellular network based upon the subscription key.
