Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging systems face challenges in efficiently charging vehicles without restrictions on parked locations, particularly in complex parking lots, where finding available chargers can be difficult and charging spaces may be occupied after charging is completed.
Innovation Solution
An electric vehicle charging system using a movable charging module that supplies electric power to fixedly disposed charging modules at multiple points, allowing the movable module to move along a preset line and connect to fixed modules to charge electric vehicles without location restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electric vehicle chargers are fixedly provided in specific parking spaces, then charging infrastructure is established, but users must find and travel to specific charging locations which increases time and complexity
Solution Approach 1:
The patent introduces a movable charging module that can dynamically relocate within the parking lot to different parking positions. Instead of users traveling to fixed chargers, the charging unit itself moves to the user's vehicle, transforming the static charging infrastructure into a dynamic system that adapts to user needs and reduces the time and effort required to access charging services.
Solution Approach 2:
The movable charging module is designed to serve multiple parking positions and multiple vehicles sequentially. By combining mobility with charging functionality, a single charging unit can replace multiple fixed chargers distributed throughout the parking lot, providing universal service across different locations without requiring users to search for specific charging spots.
2Adaptability or versatility
If charging spaces are designated in parking lots, then charging infrastructure is provided, but charging spaces may be occupied after charging completes requiring users to find new spaces
Solution Approach 1:
The movable charging module can dynamically relocate from one parking position to another after completing a charging session. This mobility eliminates the problem of occupied charging spaces because the charger automatically moves to become available for the next user, providing continuous adaptability without requiring complex manual management or reassignment of fixed charging spots.
Solution Approach 2:
The charging system operates autonomously where the movable charging module independently relocates to serve different vehicles without requiring user intervention or complex centralized management. The system self-manages the allocation and relocation of charging resources, simplifying the overall management complexity while maintaining high adaptability to user needs.
3Area of stationary object
If multiple fixed charging modules are distributed throughout the parking lot, then charging coverage is improved, but system complexity and cost increase
Solution Approach 1:
Instead of deploying multiple static charging modules throughout the parking lot, the system uses a single movable charging module that can travel to different locations. This dynamic approach achieves the same charging coverage area as multiple fixed modules but with significantly reduced system complexity and lower infrastructure costs, as the charger moves to users rather than users moving to chargers.
Solution Approach 2:
A single movable charging module performs the function of multiple fixed chargers by sequentially serving different vehicles at different parking positions. This multi-functional design eliminates the need for redundant charging infrastructure across the parking lot, reducing the number of required modules while maintaining comprehensive charging coverage throughout the area.
