Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The promotion of electric vehicles is hindered by the inefficiencies and high costs associated with manual charging processes, as current charging vehicles lack automatic walking and docking capabilities, leading to labor-intensive and error-prone charging operations.
Innovation Solution
An automatic charging vehicle equipped with an automatic walking module, power module, and automatic docking and separation device, which uses sensors and remote communication to navigate, charge, and dock with electric vehicles, reducing manpower input and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual charging process is used, then labor costs are incurred and charging efficiency is low, but automatic walking and docking functions are not achieved
Solution Approach 1:
The charging vehicle is equipped with automatic walking and automatic docking functions that enable it to autonomously navigate to the electric vehicle and connect for charging without human intervention. The system uses sensors (lidar, ultrasonic radar) to detect obstacles and automatically adjusts its positioning and docking operations, making the charging vehicle self-sufficient in performing charging tasks.
2Reliability
If dedicated parking spaces for electric vehicles are established, then charging infrastructure is provided, but construction costs and transformation costs are high
Solution Approach 1:
The charging vehicle transforms from a static charging pile concept to a mobile dynamic system. Instead of fixing charging infrastructure to specific parking locations, the charging vehicle can move freely to serve multiple electric vehicles at different locations. This dynamic approach eliminates the need for costly construction of dedicated charging parking spaces while maintaining reliable charging infrastructure.
3Measurement precision
If manual positioning is performed, then charging connection is achieved, but positioning time is long and positioning accuracy is low
Solution Approach 1:
The system replaces manual mechanical positioning with an automated control system that uses sensors (lidar, ultrasonic radar) and controllers to achieve precise positioning. The automatic docking device mechanically adjusts the connector position under controller guidance, eliminating the imprecision and time consumption of manual positioning while achieving high positioning accuracy for reliable connector engagement.
