Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
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.
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
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.
