Solution Overview

Problem

Current embedded navigation systems require frequent sign-in and restart when switching between devices, leading to inconvenience and safety issues due to the need for users to re-enter credentials, especially when leaving a vehicle temporarily.

Innovation Solution

Implementing a method for transferring and maintaining secure sessions between an embedded navigation unit and a mobile device using proximity detection and token-based authentication, allowing seamless continuation of sessions without the need for repeated sign-in, using secure channels like Bluetooth or NFC.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users switch between embedded navigation unit and mobile device, then device versatility is improved, but frequent sign-in requirements increase operational complexity and reduce ease of operation

Engineering Contradiction:
Improvedevice switching capabilityVSAvoidsign-in frequency
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary authentication by establishing a secure session between the embedded navigation unit and server before device switching occurs. Session information including authentication tokens is cached locally in both the embedded unit and mobile device, enabling seamless transitions without requiring users to re-enter credentials. The proximity detection mechanism preliminarily identifies when a mobile device should take over the session, activating the pre-cached authentication data automatically.

Inventive Principle:
Principle #10Preliminary action

2Speed

If session information is cached locally for faster access, then access speed is improved, but security risks increase due to potential unauthorized access

Engineering Contradiction:
Improvesession access speedVSAvoidsession security
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system transforms session management by introducing time-based parameters including proximity duration thresholds and session timeout values. When the mobile device remains in proximity beyond a predetermined time threshold, the system automatically transitions the session state and invalidates cached credentials on the embedded unit. This dynamic parameter adjustment maintains security while enabling fast access during legitimate use scenarios.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system implements continuous feedback through proximity detection mechanisms that monitor whether the mobile device remains near the vehicle. This feedback loop provides real-time information about device presence, enabling the system to dynamically adjust session validity and trigger automatic sign-out procedures when the device moves away, thereby maintaining security without compromising access speed during authorized sessions.

Inventive Principle:
Principle #23Feedback
