Solution Overview

Problem

Vehicle drivers face safety risks while operating navigation devices and mobile terminals simultaneously while driving, as they need to manually connect and operate both for optimal route mirroring, especially in situations with poor GPS signals or traffic congestion.

Innovation Solution

A navigation device with an auto mirroring function that connects with a mobile device via wired or wireless communication, automatically determining the need for mirroring based on route calculations, map information versions, and vehicle position, allowing for seamless route mirroring without driver intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the driver manually operates both the navigation device and mobile terminal to achieve route mirroring, then the route information can be displayed on the large screen with recent traffic information, but the driver safety is compromised due to the need to operate multiple devices while driving

Engineering Contradiction:

Improveroute information readabilityVSAvoiddriver operation safety

Core Design Contradiction:

Illumination intensityVSEase of operation

Solution Approach 1:

The navigation device automatically determines whether mirroring is needed by comparing its own route information with the mobile terminal's route information, and automatically establishes the mirroring connection without requiring driver intervention. This self-service mechanism eliminates manual operation while driving while maintaining the ability to display enhanced route information on the large screen.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary comparison of route information between the navigation device and mobile terminal before establishing mirroring. By pre-determining whether mirroring conditions are met (same route, similar destination, overlapping time period), the system avoids unnecessary manual intervention and automatically sets up the connection when beneficial, improving both safety and information display quality.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the navigation device automatically determines mirroring needs based on route calculations and map information versions, then the ease of operation is improved by eliminating manual intervention, but the device complexity increases due to additional determination functions

Engineering Contradiction:

Improveautomatic mirroring operationVSAvoidmirroring determination function

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The mirroring determinator performs only essential comparisons needed to determine if mirroring is beneficial - comparing route information, destinations, and time periods. Rather than analyzing all possible parameters, the system focuses on key criteria that sufficiently indicate whether mirroring will improve the driving experience, thus adding minimal complexity while achieving automatic operation.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The navigation device's existing route calculation and map information management functions are extended to serve the mirroring determination purpose. The same components that calculate routes and manage map versions are utilized to compare routes and determine mirroring needs, rather than adding entirely separate determination hardware, thus reducing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If the driver uses the navigation application on the mobile terminal during driving, then the navigation functionality is maintained, but the readability is insufficient compared to the large screen navigation device

Engineering Contradiction:

Improvenavigation functionality availabilityVSAvoidroute information readability

Core Design Contradiction:

ProductivityVSIllumination intensity

Solution Approach 1:

The system merges the advantages of both the mobile terminal navigation application and the vehicle navigation device by automatically mirroring the mobile device's route information onto the large navigation screen. This combination allows the driver to use the mobile app's navigation capabilities (maintaining functionality availability) while simultaneously displaying the information on the larger, more readable navigation device screen.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The navigation device acts as an intermediary that receives route information from the mobile terminal and displays it on its large screen. This intermediary function allows the mobile navigation app to continue operating independently while providing enhanced readability through the vehicle's navigation device, effectively mediating between the two systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A navigation device with the auto mirroring function includes: a first driving route calculator configured to collect a current position and a destination of the vehicle and to calculate a first driving route corresponding to the current position and the destination by using previously stored map information; a mirroring determinator configured to determine whether mirroring is required based on a predetermined mirroring condition; a start signal transmitter configured to transmit a navigation application start signal to the mobile device when it is determined that the mirroring is required; and a mirroring controller configured to receive and mirror a second driving route transmitted from the mobile device.
