Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coil units for electric power reception and transmission face challenges in cooling while minimizing volume, as they require separate cooling apparatuses for each component, leading to increased size and inefficiency.
Innovation Solution
A coil unit design incorporating a ferrite plate with a coil on one surface and devices on the opposite surface, utilizing a cooling apparatus that feeds coolant between the ferrite plate and devices to cool both simultaneously, thereby reducing overall volume and enhancing cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If separate cooling apparatuses are used for each component (coil, ferrite plate, devices), then each component can be cooled effectively, but the overall volume of the coil unit increases
Solution Approach 1:
The patent merges multiple cooling functions into a single integrated cooling apparatus. The cooling apparatus is positioned to simultaneously cool the coil, ferrite plate, and electronic devices through a unified coolant flow path, eliminating the need for separate cooling systems for each component while maintaining effective cooling of all parts.
Solution Approach 2:
The cooling apparatus is designed with multi-functionality to perform multiple cooling tasks. It includes coolant supply paths that can deliver cooling fluid to different components (coil, ferrite plate, devices) through a single apparatus, allowing one cooling system to serve multiple cooling purposes simultaneously.
2Device complexity
If devices such as rectifiers are incorporated into the coil unit, then the number of separate components is reduced, but the volume of the coil unit increases
Solution Approach 1:
The patent applies nesting by placing electronic devices within the internal structure of the coil unit. The devices are arranged in the space between the coil and ferrite plate or in dedicated mounting areas within the coil unit housing, allowing multiple components to occupy overlapping or adjacent spatial zones, thereby reducing the overall volume required.
Solution Approach 2:
The patent utilizes three-dimensional space efficiently by arranging components in multiple layers and dimensions. The coil, ferrite plate, and devices are positioned in different spatial zones and orientations within the coil unit, maximizing space utilization and minimizing the external volume of the assembly.
