Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing public electric vehicle charging facilities require multiple chargers for each vehicle, which is costly and inefficient in terms of electricity usage, necessitating electrical service upgrades and limiting scalability.
Innovation Solution
A one-to-many electric vehicle charging station with a movable charging apparatus supported by a track, utilizing contact wires and conductor poles to enable a single charger to serve multiple vehicles, with the charging apparatus translating along the track to couple with each vehicle, allowing flexible, efficient, and scalable power delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple chargers are installed for each vehicle, then each vehicle can be charged independently, but the cost and electricity consumption increase significantly
Solution Approach 1:
The charging apparatus is designed to serve multiple functions by being able to charge multiple vehicles sequentially. A single charging apparatus is shared among multiple parking spaces, allowing one charger to perform the function of multiple chargers by moving between vehicles, thereby reducing overall electricity consumption and infrastructure costs.
Solution Approach 2:
The charging apparatus is made movable along the track to dynamically serve different vehicles. Instead of having static chargers at each parking space, the system uses a dynamic charging apparatus that can be positioned at any parking space along the track, enabling flexible power delivery to multiple vehicles.
2Reliability
If multiple chargers are installed for each vehicle, then charging infrastructure is robust, but the cost and infrastructure requirements increase
Solution Approach 1:
The single charging apparatus serves multiple parking spaces, reducing the total number of chargers needed. This universal charging system maintains reliability by providing charging capability to each vehicle when needed, while significantly reducing infrastructure complexity compared to having dedicated chargers at each space.
Solution Approach 2:
The track system acts as an intermediary mechanism that enables the charging apparatus to move between parking spaces. This intermediary structure simplifies the overall infrastructure by replacing multiple complex charger installations with a single moving charger and a simple track system.
3Device complexity
If a single charger serves multiple vehicles, then cost and electricity consumption are reduced, but the charging apparatus must move between vehicles
Solution Approach 1:
The system enables self-service charging where vehicles can be charged in sequence without requiring manual intervention to switch between chargers. The charging apparatus automatically moves along the track to serve different vehicles, and the system can operate autonomously to provide charging services to multiple vehicles efficiently.
