Solution Overview

Problem

Traditional navigation systems require constant user input to start and stop turn-by-turn directions, which can be distracting and inefficient, especially when users are familiar with parts of their journey, and fail to provide other navigation benefits like traffic alerts without full direction display.

Innovation Solution

A navigation system that allows users to navigate without turn-by-turn directions for familiar areas, providing traffic event notifications and engaging micro navigation modes only when needed, optimizing resource use and minimizing distractions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional turn-by-turn navigation is provided for the entire journey, then the user receives complete directional guidance, but the user experiences driver distraction and battery consumption increases

Engineering Contradiction:

Improvedirectional guidanceVSAvoidbattery consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent segments the navigation journey into two distinct phases: (1) a first portion where freedom navigation mode is active and turn-by-turn directions are suppressed, and (2) a second portion where micro navigation mode engages and provides targeted turn-by-turn directions only when needed. This segmentation allows the system to reduce battery consumption during familiar routing portions while providing directional guidance when actually needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies partial action by providing turn-by-turn directions only for the portion of the journey where they are actually needed (the second portion), rather than for the entire journey. The system determines when to engage micro navigation mode based on whether the device is traveling along a determined route, providing directions partially rather than continuously, thus reducing energy consumption while maintaining necessary guidance.

Inventive Principle:

Principle #16Partial or excessive action

2Use of energy by moving object

If freedom navigation mode is used without turn-by-turn directions, then battery life is conserved and distractions are reduced, but the user may lose access to timely traffic event notifications

Engineering Contradiction:

Improvebattery lifeVSAvoidtraffic event notifications

Core Design Contradiction:

Use of energy by moving objectVSLoss of information

Solution Approach 1:

The patent implements feedback mechanisms where the system continuously monitors whether the device is traveling along a determined route. When the device deviates from the route or when micro navigation mode conditions are met, the system provides feedback by engaging turn-by-turn directions. Additionally, traffic event notifications are provided as feedback to keep the user informed without requiring continuous turn-by-turn direction display.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces traffic event notifications as an intermediary mechanism that bridges the gap between freedom navigation mode and full turn-by-turn navigation. These notifications provide essential information about traffic events, road closures, and routing changes without requiring the user to engage full turn-by-turn direction display, thus maintaining battery savings while preventing information loss.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If the system automatically engages turn-by-turn navigation based on route deviation, then navigation accuracy is improved, but user control is reduced

Engineering Contradiction:

Improvenavigation accuracyVSAvoiduser control

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic mode switching between freedom navigation mode and micro navigation mode based on real-time conditions. The system dynamically determines whether to engage turn-by-turn directions by monitoring route adherence and navigation state, allowing the navigation approach to adapt to current driving conditions while maintaining user control through the ability to switch modes as needed.

Inventive Principle:

Principle #15Dynamics

AI summary

Systems and methods are provided herein for engaging navigation modes based on traffic events. For example, the disclosed system receives a request for navigating a user device from a start location to a final destination. The user device optionally indicates that turn-by-turn navigational directions are to be provided from an intermediate location to the final destination. The system determines all possible routes the user device can take from the start location to the intermediate location and, in some embodiments, from the intermediate location to the final destination. Once engaged, the system monitors the user device's progress from the start location to the intermediate location without displaying turn-by-turn navigation. During which time, the system notifies the user device of any traffic events that may impact the journey. When prompted, the system provides turn-by-turn navigational directions to bypass the traffic event. Once the user device has successfully bypassed the traffic event, the system resumes monitoring the user device's progress without displaying turn-by-turn navigation. Once the user device reaches a predetermined distance from the intermediate location, the system provides turn-by-turn navigational directions from that location to the final destination.
