Magnetizable Concrete Pavement Coils for Scalable Wireless Charging
Solution Overview
Problem
Existing wireless charging systems for vehicles require complex installation processes and materials that are not efficiently integrated into concrete pavements, limiting their effectiveness and scalability.
Innovation Solution
A wireless power transfer transmitter system is constructed using a magnetizable concrete mixture with embedded transmitter coils, allowing for in-place formation of a wireless charging infrastructure within drivable civil structures, such as roads, using a concrete paving machine to embed pre-manufactured coils and magnetic particles, enabling both static and dynamic charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wireless charging systems are installed in concrete pavements, then wireless charging capability is achieved, but construction complexity and installation time increase
Solution Approach 1:
The patent combines the transmitter coil installation with the concrete pavement construction process itself. The coil is placed in a formwork before concrete is poured, merging two separate processes (coil installation and pavement construction) into one integrated operation, thereby reducing construction complexity and time
Solution Approach 2:
The concrete pavement serves multiple functions: it provides the structural road surface and simultaneously houses the wireless charging transmitter coil. This multi-functional design allows the pavement to be both a transportation surface and a charging infrastructure, reducing the need for separate charging equipment installation
2Reliability
If transmitter coils are embedded in concrete pavement, then wireless charging efficiency improves, but installation time and construction costs increase
Solution Approach 1:
The transmitter coil is pre-positioned in the formwork before concrete pouring begins. This preliminary placement ensures the coil is correctly positioned for optimal charging efficiency while being integrated into the pavement construction timeline, avoiding post-construction installation delays
Solution Approach 2:
The patent merges the coil installation step with the concrete pouring step. By placing the coil in the formwork and then pouring concrete over it in sequence during the same construction operation, the total installation time is reduced while maintaining proper coil embedding for efficient wireless charging
3Adaptability or versatility
If complex installation processes are used for wireless charging systems, then charging functionality is achieved, but scalability and deployment speed are limited
Solution Approach 1:
The pavement construction process is designed to simultaneously create both the road infrastructure and the wireless charging infrastructure. This universal approach allows standard pavement construction teams and processes to deploy charging functionality across multiple locations without requiring specialized installation procedures, thereby improving scalability and deployment speed
