Solution Overview

Problem

Existing technologies face inefficiencies in managing subscriptions for applications that run across multiple devices, particularly in maintaining anonymity and seamless transfer of subscriptions without requiring user credentials, leading to duplicate payments and limited device usage.

Innovation Solution

A subscription manager system that allows for anonymous subscription propagation across devices, enabling a single subscription payment for multiple devices while maintaining user anonymity, and managing device capabilities based on subscription status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user credentials are required for subscription verification, then access control reliability is improved, but user privacy and ease of operation deteriorate

Engineering Contradiction:

Improveaccess control reliabilityVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system segments the authentication process by separating device identification from user credential verification. Each device receives a unique device token that can be independently verified without requiring user login credentials, enabling subscription verification to be divided into device-level and user-level components

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system introduces device tokens as an intermediary mechanism between the application server and user authentication. These tokens serve as mediators that carry subscription verification information without requiring direct user credential exchange, thus maintaining both security and privacy

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If user credentials are required for subscription verification, then access control reliability is improved, but user privacy deteriorates

Engineering Contradiction:

Improveaccess control reliabilityVSAvoiduser privacy

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system extracts user credential requirements from the device-level subscription verification process. By removing the necessity of user credentials for device authorization and using only device tokens, the system takes out the privacy-intrusive element while maintaining access control reliability through alternative verification mechanisms

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system creates device-specific copies of authentication credentials in the form of device tokens. These tokens are unique to each device and contain the necessary subscription verification information without requiring access to actual user credentials, thus preserving privacy while enabling reliable verification

Inventive Principle:

Principle #26Copying

3Reliability

If subscriptions are managed per-device independently, then device-specific access control is improved, but system complexity and duplicate payments increase

Engineering Contradiction:

Improvedevice-specific access controlVSAvoidsubscription management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system merges multiple device subscription management into a unified cloud-based structure. The server consolidates device token information and subscription status across all devices, allowing centralized management that reduces complexity while maintaining device-specific access control through the token verification mechanism

Inventive Principle:

Principle #5Merging (Combining)

4Adaptability or versatility

If subscriptions are transferred between devices, then adaptability is improved, but subscription management complexity increases

Engineering Contradiction:

Improvesubscription transfer capabilityVSAvoidsubscription management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements dynamic subscription management where device tokens can be reassigned and transferred between devices through the cloud server. This dynamic approach allows subscriptions to adapt to different devices without requiring complex manual reconfiguration, as the server automatically updates token associations based on registration and authentication events

Inventive Principle:

Principle #15Dynamics

AI summary

For example, a computing system may be configured to provide a first computing device and a second computing device, which is paired with the first computing device, with access to a subscription-restricted service of an application, for example, based on a subscription confirmation to confirm a subscription to the subscription-restricted service. For example, the computing system may be configured to identify a pairing between the first computing device and a third computing device, which is unsubscribed to the subscription-restricted service, and to assign the third computing device to the subscription and provide the third computing device with access to the subscription-restricted service, for example, based on the identification of the pairing between the first computing device and the third computing device.
