Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional navigation systems cannot automatically obtain users' destinations or provide optimal routes, and lack a direct mechanism for modifying routes based on feedback from other users, leading to inconvenient communication methods for route adjustments.

Innovation Solution

A navigation system with a data server that receives requests for route modifications from a first user terminal, generates and transmits route information using a geographical database, and allows a second user terminal to modify and transmit the route information back to the first terminal, enabling direct route information modification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional navigation systems provide automated route guidance, then navigation service is available, but the system cannot automatically obtain user destinations or provide optimal routes satisfying user needs

Engineering Contradiction:

Improveroute customization capabilityVSAvoiduser input requirement

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism where another user can provide feedback on the generated route information through the communication unit. This feedback allows the first user to adjust and optimize the route based on real-time input from someone with local knowledge, thereby achieving route customization without requiring the first user to manually input all route details

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The communication unit serves as an intermediary that connects the first user terminal with another user terminal. This intermediary enables indirect route planning where the first user benefits from another user's local knowledge without direct manual intervention, resolving the contradiction between automated navigation and route optimization

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If users ask for route information from another person who knows the destination, then accurate route guidance can be obtained, but communication through separate channels like telephone calls is inconvenient and inefficient

Engineering Contradiction:

Improveroute information accuracyVSAvoidcommunication convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent merges the navigation function with the communication function into a single integrated system. The communication unit is directly integrated into the navigation terminal, allowing users to communicate with another user about route information through the same device used for navigation, eliminating the need to switch between separate communication channels like telephone calls

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The navigation terminal itself acts as an intermediary that facilitates direct communication between users about route information. This intermediary enables accurate route information exchange while maintaining ease of operation, as users can communicate through the navigation interface rather than switching to external communication tools

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If conventional navigation systems display static route information, then navigation guidance is provided, but the route cannot be directly modified by another user in real-time

Engineering Contradiction:

Improveroute modification capabilityVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transforms the static route display into a dynamic system where route information can be modified in real-time. The display unit updates the route information based on feedback received from another user through the communication unit, allowing the route to adapt dynamically without requiring complex manual intervention from the first user

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements a feedback loop where another user can provide input on the displayed route information, and this feedback is automatically processed to update the route. This feedback mechanism enables real-time route modification while keeping the system structure relatively simple, as the updates are automatically applied without requiring complex manual editing interfaces

Inventive Principle:

Principle #23Feedback

AI summary

According to the first aspect of the present invention, there is a data server (110) providing modified route information to a first user terminal (130) used by a first user, comprising a receiving unit (114) configured to receive a request from the first user terminal for requesting a second user terminal (120) used by a second user to modify route information, a geographical database (113) configured to store geographical data, a route information generation unit (112) configured to generate the route information indicating a route from a first location to a second location, using the geographical data, and a transmitting unit (115), configured to transmit a route modification request with the generated route information to the second user terminal. The receiving unit is further configured to receive modified route information from the second user terminal (120). The transmitting unit is further configured to transmit the modified route information to the first user terminal (130).
