Solution Overview

Problem

Conventional navigation systems fail to efficiently guide users to visit multiple transit points, such as tourist spots and charging stations, while considering user preferences and battery charging needs.

Innovation Solution

A route guidance apparatus that acquires user request information and event information for each transit point, calculates a matching degree based on user priorities, and decides a go-around route that includes transit points with higher matching degrees and charging stations, optimizing travel distance and time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional navigation systems guide users to a single destination, then the route is simple and easy to follow, but the user cannot efficiently visit multiple transit points such as tourist spots and charging stations

Engineering Contradiction:
Improveefficiency of visiting multiple transit pointsVSAvoidcomplexity of route guidance system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the route guidance function into multiple specialized units: an acquisition unit that collects user requests and event information, a selection unit that identifies transit points based on matching degrees, and a decision unit that determines the optimal go-around route. This segmentation allows the system to handle multiple transit points efficiently while maintaining manageable complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts route guidance based on real-time inputs including user preferences, event information at transit points, and battery status. The selection unit calculates matching degrees dynamically, and the decision unit optimizes the go-around route considering changing conditions such as charging needs and visit priorities, making the system adaptable rather than static.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the system prioritizes visiting multiple transit points, then user preferences and event participation improve, but travel time and distance increase

Engineering Contradiction:
Improveability to satisfy user preferences and event participationVSAvoidtravel time for go-around route
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The acquisition unit collects user requests and sets priorities in advance before route calculation. The selection unit pre-identifies suitable transit points by calculating matching degrees between user preferences and event information. This preliminary preparation allows the decision unit to optimize the go-around route efficiently, balancing transit point visits with reasonable travel time by having all necessary information ready before route determination.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes key parameters including the matching degree calculation (which incorporates user priority settings), the route optimization criteria (which considers both distance/time and transit point visits), and the battery status threshold for including charging stations. By adjusting these parameters based on user preferences and real-time conditions, the system achieves adaptability while controlling travel time through intelligent parameter selection.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the system includes charging stations in the route, then battery depletion risk is reduced, but the route complexity and decision-making process increase

Engineering Contradiction:
Improvebattery charge availability during travelVSAvoidcomplexity of route decision unit
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The selection unit pre-identifies charging stations among candidate transit points by checking their charging capabilities before the decision unit finalizes the route. The decision unit then simply includes or excludes these pre-identified charging stations based on battery status thresholds, rather than performing complex real-time optimization. This preliminary identification reduces the decision-making complexity while ensuring reliable battery charge availability.

Inventive Principle:
Principle #10Preliminary action

4Measurement precision

If the system calculates matching degrees for all candidate transit points, then transit point selection accuracy improves, but computational load increases

Engineering Contradiction:
Improveaccuracy of transit point selectionVSAvoidcomputational power required
Core Design Contradiction:
Measurement precisionVSPower

Solution Approach 1:

The selection unit calculates matching degrees for all candidate transit points to ensure comprehensive and accurate selection, even though this requires significant computational power. The system accepts the excessive action of calculating all matching degrees rather than using approximation methods, prioritizing selection accuracy over computational efficiency. This approach ensures that no potentially suitable transit point is missed due to incomplete evaluation.

Inventive Principle:
Principle #16Partial or excessive action
