Solution Overview

Problem

Travelers, especially those visiting foreign countries, often face confusion and safety risks due to unfamiliarity with local traffic rules when approaching intersections, as rules can vary significantly between countries and even within regions, leading to potential accidents.

Innovation Solution

A portable electronic device equipped with a GPS receiver, map database, and user interface that provides navigation instructions and reminds users of specific traffic rules related to their current location when approaching intersections, indicating the correct side and lane for turns, yielding, and other intersection-specific guidelines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If basic navigation instructions are provided, then users can receive route guidance, but users traveling in foreign countries cannot familiarize themselves with local traffic rules

Engineering Contradiction:

Improveadaptability to local traffic rulesVSAvoidloss of traffic rule information

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system pre-loads and stores traffic rule information for multiple countries and regions in advance. When a user travels to a foreign country, the relevant traffic rules are already available in the device's database, enabling immediate adaptation without requiring real-time information retrieval.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the user's current location via GPS and automatically activates the appropriate traffic rule set for that region. This feedback mechanism ensures that the correct local traffic rules are displayed based on the user's geographical position, enhancing adaptability to local conditions.

Inventive Principle:

Principle #23Feedback

2Reliability

If generic navigation instructions are provided, then device complexity is minimized, but user safety at intersections is compromised

Engineering Contradiction:

Improveuser safetyVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system enhances navigation instructions with location-specific quality attributes. At intersections, it provides detailed local traffic rule information such as right-of-way rules, signal meanings, and pedestrian crossing protocols specific to that geographic location, thereby improving safety without requiring complete system redesign.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The navigation system is segmented into modular components: basic route guidance, location detection, traffic rule database, and intersection-specific assistance. This segmentation allows the addition of safety features without significantly increasing overall device complexity, as each module operates independently.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If detailed traffic rule information is provided at all intersections, then user familiarity with local rules improves, but information overload and user confusion increases

Engineering Contradiction:

Improveuser familiarity with traffic rulesVSAvoiduser confusion

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system applies partial action by providing detailed traffic rule information selectively only at intersections rather than continuously along the entire route. This targeted approach delivers necessary local knowledge without overwhelming the user with unnecessary information during straight-road segments.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system activates detailed traffic rule reminders periodically at relevant intersections based on GPS detection. Information is presented in discrete, timed intervals rather than continuously, allowing users to process information at manageable intervals and reducing overall confusion.

Inventive Principle:

Principle #19Periodic action

AI summary

A method of providing intersection assistance with a portable electronic device to remind a user of traffic rules when the user approaches traffic intersections includes receiving an input from the user indicating a destination location for generating navigation instructions to the destination location, determining a current location of the portable electronic device according to received position signals, providing navigation instructions to the destination location according to the current location of the portable electronic device, and reminding the user of traffic rules related to intersections for a geographical location in which the portable electronic device is currently located when the portable electronic device detects that the portable electronic device is approaching an intersection, where reminding the user of traffic rules related to intersections comprises indicating a side of a second road the user should turn onto when making a turn from a first road onto the second road.
