Solution Overview

Problem

The installation and maintenance of smart charging stations for electric vehicles and energy supply stations at locations without existing internet connectivity, such as parking garages, are costly and inefficient due to the need for manual data collection and billing processes.

Innovation Solution

A system comprising an energy station, a mobile terminal, and a computing device that allows data transmission between the energy station and the computing device via the mobile terminal, even without an immediate connection, enabling billing data to be collected and transmitted once a network connection is established, and allowing bidirectional communication for configuration, updates, and pre-paid transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If smart charging stations are installed in locations without existing internet connectivity, then the charging station network can be expanded to more locations, but the installation cost and complexity increase due to the need for internet connection infrastructure

Engineering Contradiction:
Improvecharging station network coverageVSAvoidinstallation infrastructure requirement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mobile terminal acts as an intermediary device between the energy station and the computing device. It receives data from the energy station's communication device and transmits it to the computing device, enabling data communication without requiring a direct internet connection at the energy station location. This mediator approach resolves the contradiction by allowing network expansion to remote locations while avoiding complex infrastructure installation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If manual data collection and billing processes are used at locations without internet connection, then internet infrastructure is not required, but the operational costs and time consumption increase

Engineering Contradiction:
Improveinstallation simplicityVSAvoidbilling operation efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The system enables automated billing operations through the mobile terminal that collects data from the energy station and automatically transmits it to the computing device for processing. This self-service mechanism eliminates the need for manual data collection and billing operations, resolving the contradiction by maintaining installation simplicity while significantly improving operational efficiency through automation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mobile terminal preliminarily collects and stores billing data at the energy station location before transmitting it to the computing device. This preliminary action ensures that data is captured at the source without requiring immediate internet connectivity, and the subsequent transmission occurs automatically when the mobile terminal is available, thereby maintaining both installation simplicity and operational efficiency.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If a permanent internet connection is required at the energy station, then billing data can be transmitted immediately, but the installation effort and cost increase significantly

Engineering Contradiction:
Improvebilling data transmission reliabilityVSAvoidinstallation time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The mobile terminal serves as a portable intermediary that bridges the energy station and the computing device. It reliably collects billing data from the energy station and transmits it to the computing device when connected, ensuring data transmission reliability without requiring permanent internet infrastructure at the energy station, thereby eliminating installation time while maintaining information integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)
