Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In densely populated urban areas, installing vehicle chargers for parked electric vehicles is costly and disrupts sidewalk accessibility, especially for individuals with disabilities, due to the need for excavation and potential obstacles.
Innovation Solution
A vehicle power adaptor that connects to electrical road tracks, allowing for power transfer to parked vehicles without the need for on-vehicle power collectors, featuring a control module for secure and controlled charging, a user identification system, and a design that includes attachment means and a heating element to ensure secure and safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle chargers are installed in parking facilities, then electric vehicles can be charged, but sidewalk accessibility is degraded and installation costs increase
Solution Approach 1:
The patent introduces an electrical road track embedded in the road surface as an intermediary power transmission medium. This allows power to be delivered to vehicles through the road itself rather than through above-ground charging infrastructure, thus maintaining sidewalk accessibility while enabling vehicle charging.
Solution Approach 2:
The patent replaces the mechanical charging infrastructure (above-ground chargers, cabling, and connectors) with an electrical road track system that uses electromagnetic fields for wireless power transfer, eliminating the need for physical charging stations along sidewalks.
2Ease of operation
If above-ground charging infrastructure is installed, then vehicles can be charged, but installation costs and urban environment impact increase
Solution Approach 1:
The patent replaces complex mechanical charging infrastructure with an electrical road track system using wireless electromagnetic power transfer, significantly reducing installation complexity and cost by eliminating the need for above-ground cabling and charging stations.
Solution Approach 2:
The electrical road track serves multiple functions: it provides power transmission, acts as a road surface, and can be integrated into existing road infrastructure, reducing the need for separate charging infrastructure installation.
3Object-affected harmful factors
If electrical road tracks are used for power transfer, then sidewalk accessibility is maintained, but new infrastructure installation is required
Solution Approach 1:
The patent merges the power transmission function with the existing road infrastructure by embedding electrical road tracks within the road surface, combining two functions (road surface and power transmission) into a single integrated system.
Solution Approach 2:
The electrical road track is designed to serve as both a functional road surface and a power transmission medium, allowing existing road infrastructure to be dual-purpose and reducing the need for separate charging infrastructure.
