Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless vehicle charging systems face inefficiencies due to the difficulty in aligning transmission and reception units when a vehicle is not parked correctly, affecting charging efficiency based on the positions of these units.
Innovation Solution
A vehicle wireless charging guidance system that utilizes an around view monitoring (AVM) unit to display real-time position information of the power transmission and reception modules, allowing drivers to park their vehicles optimally for efficient charging by providing position guidance and image information around the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless charging is performed without position guidance, then the charging process can start quickly, but the charging efficiency is low due to poor alignment between transmission and reception units
Solution Approach 1:
The AVM screen serves as an intermediary display device that shows position information of the power transmission module and power reception module to the driver. This mediator enables the driver to understand the alignment status without adding complex control mechanisms to the charging system itself, thus improving charging efficiency while maintaining system simplicity
Solution Approach 2:
The system provides real-time feedback by displaying position information on the AVM screen, allowing the driver to see how well the vehicle is aligned with the charging modules. This feedback loop enables the driver to make adjustments to improve alignment and charging efficiency without requiring complex automated control systems
2Manufacturing precision
If the driver manually adjusts vehicle position without position information display, then the system remains simple, but the alignment between power transmission module and power reception module is poor
Solution Approach 1:
The AVM screen acts as an intermediary that provides position information to the driver, enabling precise alignment without complicating the operation. The driver can see the relative positions of transmission and reception modules and make informed adjustments, achieving high alignment precision while maintaining ease of operation
Solution Approach 2:
The system replaces complex mechanical alignment mechanisms with an information-based approach. Instead of using mechanical guides or automated positioning systems, the invention uses visual information display on the AVM screen to guide the driver, substituting mechanical complexity with informational clarity
