Solution Overview

Problem

In wireless power transfer systems, the power feeding performance varies due to factors like coil distance and circuit element configurations, making it challenging to present a compatible charging station that meets the user's requirements, and users also consider factors other than power feeding performance when choosing a charging station.

Innovation Solution

An information providing system that extracts and outputs location information of charging stations with power transmitters compatible with a specific power receiver by referencing a station storage unit and a history storage unit, which stores usage history and station information, allowing users to select based on compatibility, price, and performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If charging station location information is provided based on general availability, then users can access charging stations, but power feeding performance compatibility cannot be guaranteed

Engineering Contradiction:
Improvecharging station compatibilityVSAvoidpower feeding performance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary matching between power receiver specifications and power transmitter capabilities before the user visits the charging station. By pre-storing specification information and performing compatibility checks in advance, the system ensures that users are directed to charging stations that are guaranteed to be compatible with their specific power receiver, thereby resolving the contradiction between general availability and performance reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system incorporates feedback mechanisms where power feeding results and usage history are stored and used to improve future recommendations. By analyzing actual power feeding performance data and user preferences, the system refines its matching algorithm to provide more accurate compatibility assessments, ensuring both adaptability and reliability in charging station recommendations.

Inventive Principle:
Principle #23Feedback

2Reliability

If charging station recommendations are based on power feeding performance only, then compatibility is improved, but user preferences for other factors cannot be considered

Engineering Contradiction:
Improvepower feeding performanceVSAvoiduser preference accommodation
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs multiple functions simultaneously: it evaluates power feeding performance compatibility, analyzes user preferences, checks usage history, and considers various charging station attributes. By integrating these diverse evaluation criteria into a unified recommendation system, the system can provide charging station recommendations that satisfy both technical compatibility requirements and user preferences, thereby resolving the contradiction between reliability and adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If all charging station information is stored and processed centrally, then comprehensive matching is achieved, but system complexity increases

Engineering Contradiction:
Improvecharging station matching accuracyVSAvoidinformation processing system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments information storage and processing across multiple components: power receiver specification information is stored separately, power transmitter information at charging stations is stored separately, and usage history is stored independently. This segmentation allows the system to achieve comprehensive matching accuracy while managing complexity through modular information architecture, where each component can be maintained and updated independently.

Inventive Principle:
Principle #1Segmentation
