Solution Overview

Problem

Navigating to an unknown destination using existing navigation devices can be challenging due to the lack of detailed information about the destination's appearance and surrounding environment, leading to user uncertainty and increased journey time.

Innovation Solution

A navigation device and method that provide a user-selected destination with enhanced pseudo three-dimensional views, including building representations and information markers for entrance and parking locations, to facilitate easier navigation to unfamiliar destinations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional map display is used, then device complexity is low, but user uncertainty about destination increases

Engineering Contradiction:
Improvedestination informationVSAvoiddisplay complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent transitions from traditional two-dimensional map displays to pseudo-three-dimensional building representations. This dimensional enhancement provides users with a more realistic view of destination buildings and surrounding environment, reducing uncertainty about the destination's appearance and location while maintaining manageable device complexity through software-based rendering.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The system generates and displays destination preview information before the user arrives at the destination. By showing pseudo-3D building views and surrounding environment in advance, users can familiarize themselves with the destination's appearance and location, reducing arrival uncertainty and search time without requiring complex real-time processing.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If detailed destination information is provided, then user uncertainty decreases, but processing time increases

Engineering Contradiction:
Improvedestination informationVSAvoidprocessing time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system provides selectively detailed information rather than complete exhaustive data. It generates pseudo-3D representations and key destination features that are sufficient to reduce user uncertainty about the destination's appearance and location, without processing and displaying all possible detailed information, thus balancing information completeness with processing efficiency.

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If pseudo three-dimensional views are provided, then ease of operation improves, but device complexity increases

Engineering Contradiction:
Improvenavigation easeVSAvoiddisplay complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system creates simplified pseudo-three-dimensional copies or representations of actual buildings and surrounding environment rather than using full three-dimensional models. This copying approach provides enhanced visual information for easier navigation while keeping the data structure and processing requirements manageable, avoiding the complexity of complete 3D modeling.

Inventive Principle:
Principle #26Copying
