Solution Overview

Problem

Conventional navigation devices face difficulties in receiving input information from users other than the intended user, limiting remote operation capabilities.

Innovation Solution

A navigation system comprising a navigation device, a telematics server, and a computer that enables remote control operations through a network, allowing another user to instruct and control the navigation device via a telematics server that intermediates input-output information, converting remote control operations into instructions executable by the navigation device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional navigation devices are used with manual operation, then the device can guide routes accurately, but another user cannot remotely control the device

Engineering Contradiction:
Improveremote control capabilityVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A telematics server is introduced as an intermediary between the navigation device and the remote control device. The server receives remote control operations from a user's terminal, converts them into executable instructions, and transmits them to the navigation device. This mediator approach enables remote control functionality without directly modifying the navigation device's internal structure, thus improving adaptability while managing complexity through a separate service layer.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the navigation device requires manual input from the user, then operation control is simple, but another user cannot operate the device remotely

Engineering Contradiction:
Improveuser operation convenienceVSAvoidmulti-user control
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The navigation device is designed to accept operations from multiple sources: manual input from the primary user and remote control operations from other users via the telematics server. The device maintains its original simple operation interface while adding universal compatibility with remote control signals, enabling both single-user simplicity and multi-user versatility through a unified operation handling system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If remote control operations are implemented without a server, then system complexity is reduced, but operation conversion and transmission cannot be achieved

Engineering Contradiction:
Improveremote operation efficiencyVSAvoidsystem architecture
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The telematics server serves as a centralized intermediary that handles the complex tasks of receiving remote control operations, converting them into executable instructions, and transmitting them to the navigation device. This architecture improves remote operation efficiency by centralizing the conversion logic in the server rather than embedding it in the navigation device, thereby maintaining device simplicity while achieving sophisticated remote control functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Provided is a navigation technique which allows a person other than a user who received a route guide to operate a navigation device through an interaction process. The navigation device is characterized by being provided with an instruction reception unit, a process unit, and an output unit. The instruction reception unit receives an instruction for a process from an external device. The process unit executes a process in accordance with the instruction received by the instruction reception unit. The output unit outputs output information which is obtained as the result of the process executed by the process unit.
