Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is costly to provide a large number of facilities for power transfer between a power network and vehicles, especially in locations where vehicles gather, such as event venues, due to the difficulty in efficiently managing and balancing power supply and demand.
Innovation Solution
A portable power transfer unit that can be deployed at event venues or other locations with high vehicle concentration, equipped with a processing unit, power storage devices, and communication capabilities, allowing bidirectional power transmission between vehicles and the power network, and controlled by a managing apparatus to balance power supply and demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If facilities for power transfer are provided at locations where vehicles gather, then power transfer capability is improved, but cost increases
Solution Approach 1:
The power transfer system is divided into multiple portable power transfer units that can be independently deployed and managed. Each unit can serve multiple vehicles simultaneously, allowing the system to scale flexibly according to demand rather than requiring a single large-scale fixed facility
Solution Approach 2:
The system uses portable power transfer units that can be dynamically deployed to locations where vehicles gather based on real-time demand. The managing apparatus dynamically allocates and controls these units, allowing the system to adapt to varying vehicle concentrations and power transfer needs without maintaining permanent facilities everywhere
2Adaptability or versatility
If facilities for power transfer are provided at locations where vehicles gather, then power transfer capability is improved, but facility management complexity increases
Solution Approach 1:
The managing apparatus serves multiple functions: it manages multiple portable power transfer units, communicates with multiple vehicles, monitors power supply and demand across the entire system, and performs load balancing. This centralized multi-functional management reduces the complexity that would otherwise arise from managing multiple separate facilities
Solution Approach 2:
The system implements continuous feedback loops where the managing apparatus monitors power supply and demand conditions, vehicle states, and unit performance. Based on this feedback, the system automatically adjusts power allocation and unit deployment, enabling efficient management without requiring complex manual intervention at each facility location
