Solution Overview

Problem

The existing digital key authorization systems face resource and time-intensive registration processes at Key Tracking Servers, necessitating improved key tracking data collection, especially in offline scenarios.

Innovation Solution

Storing key usage data in a secured storage device of user equipment (UE) allows for offline digital key generation and simplified data collection by eliminating the need for real-time communication links with backend systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time communication link with backend is required for digital key registration and tracking, then key tracking data collection can be performed continuously, but resource and time intensive registration processes occur and network dependency increases

Engineering Contradiction:

Improvekey tracking data collectionVSAvoidregistration process time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-storing digital key data and usage information locally in the secured storage device of user equipment before any tracking is needed. This allows the system to perform key tracking data collection without requiring real-time communication with backend systems, eliminating the time-consuming registration processes while maintaining reliable tracking capability.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If real-time communication link with backend is required for digital key operations, then centralized control is maintained, but system complexity and network dependency increase

Engineering Contradiction:

Improvedigital key operationsVSAvoidcommunication infrastructure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the digital key data and usage tracking functionality from the backend system and places it locally in the secured storage device of user equipment. This extraction allows digital key operations to be performed independently without requiring complex communication infrastructure, while centralized control is maintained through periodic synchronization when devices are online.

Inventive Principle:

Principle #2Taking out (Extraction)

3Loss of information

If continuous network connectivity is required for digital key generation, then real-time synchronization is achieved, but offline key generation is prevented

Engineering Contradiction:

Improvekey usage data synchronizationVSAvoidoffline operation capability

Core Design Contradiction:

Loss of informationVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamics by enabling the system to adapt between online and offline modes. In offline mode, digital key generation and usage tracking occur locally using stored data. When connectivity is restored, the system dynamically synchronizes the stored usage data with the backend, ensuring information consistency while maintaining offline operational versatility.

Inventive Principle:

Principle #15Dynamics
