Power Transmitting Coil Layout With Nested Capacitor Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power transmitting coil units require a housing to protect electronic components, making it difficult to achieve a smaller size or reduced weight, which complicates transport and placement.
Innovation Solution
The power transmitting coil unit is designed without a housing by using a core with a hole to create a capacitor holding space, where capacitors are housed, and a load support member is used to protect the capacitors, allowing for a thinner, more portable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a housing is used to protect electronic components, then reliability is improved, but weight and size increase
Solution Approach 1:
The patent extracts and removes the housing from the conventional power transmitting coil unit structure. Instead of using a separate housing to protect electronic components, the invention integrates protection functions into the core structure itself, eliminating the need for additional protective enclosures and thereby reducing overall weight.
Solution Approach 2:
The patent merges the protective function with the core structure. The core is designed to simultaneously serve as both the functional magnetic component and the protective structure for electronic components, combining multiple functions into a single integrated element rather than using separate housing and core components.
2Reliability
If a housing is used to protect electronic components, then reliability is improved, but size increases
Solution Approach 1:
The patent removes the housing component from the conventional design, extracting the protective function and redistributing it across other structural elements. This elimination of the housing allows for a more compact overall size while maintaining component protection through alternative means.
Solution Approach 2:
The patent implements a nested arrangement where electronic components are positioned within the central hole of the core structure. This nesting approach allows components to be housed within the core's internal space rather than requiring external housing, thereby reducing the overall footprint and size of the power transmitting coil unit.
3Device complexity
If a housing is used to protect electronic components, then device complexity is reduced, but weight and size increase
Solution Approach 1:
The patent combines multiple functions into fewer components. The core structure simultaneously provides magnetic functionality, mechanical support, and protective enclosure for electronic components. This merging reduces the total number of parts and simplifies the overall device structure while eliminating the weight penalty of separate housing components.

AI summary
A power transmitting coil unit includes a board on which a coil comprised of a conductor pattern is formed and to a back surface side of which capacitors are mounted, a core arranged at a back surface side of the board and formed with a hole at a position facing the capacitors, a bottom plate arranged at a back surface side of the core, a space formed defined by a back surface of the board, a front surface of the bottom plate, and an inner circumferential surface of the hole and in which the capacitors are housed, and support member arranged in the space and supporting the board.
