Stackable Inductor with Standoffs for Compact Power Supply Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supplies require larger layouts due to the side-by-side mounting of inductor and transistor components, which limits space efficiency.
Innovation Solution
The use of a stacked configuration where the inductor component is mounted over the transistor components, facilitated by standoffs that allow for reduced layout area by enabling vertical stacking, thereby reducing the overall size of the power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If inductor and transistor components are mounted side by side, then electrical connectivity and heat dissipation are maintained, but layout area increases
Solution Approach 1:
The patent transitions from a two-dimensional side-by-side mounting arrangement to a three-dimensional stacked configuration. The inductor component is positioned vertically above the transistor component, utilizing the vertical dimension (Z-axis) to reduce the horizontal footprint while maintaining functional relationships through vertical alignment of electrical connections and thermal pathways.
Solution Approach 2:
The inductor component is nested directly over the transistor component, with the transistor housed within the footprint of the inductor. This nesting arrangement allows the smaller transistor component to be contained within the spatial envelope of the larger inductor, maximizing space utilization and reducing overall layout area while maintaining electrical and thermal connectivity.
2Area of stationary object
If components are stacked vertically, then layout area is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent divides the power supply into distinct modular components - the transistor component with its own housing and the inductor component with integrated standoffs. This segmentation allows each component to be manufactured and tested independently using conventional processes, then assembled together in a vertical stack, reducing overall manufacturing complexity despite the three-dimensional arrangement.
Solution Approach 2:
The standoffs integrated into the inductor component's housing serve as intermediaries that facilitate the vertical stacking arrangement. These standoffs provide mechanical support, electrical isolation, and alignment features that simplify the assembly process by enabling straightforward vertical mounting of the inductor over the transistor without requiring complex positioning or additional fastening mechanisms.
3Area of stationary object
If standoffs are used to enable stacking, then layout area is reduced, but device complexity increases
Solution Approach 1:
The patent merges the standoff support structures directly into the inductor component's housing, eliminating the need for separate standoff parts. This integration combines multiple functions - mechanical support, electrical isolation, and structural alignment - into a single unified component, reducing the total part count and assembly complexity while enabling the space-saving vertical stacking arrangement.
Solution Approach 2:
The inductor housing is designed with multi-functional standoffs that simultaneously provide mechanical support for vertical stacking, electrical isolation between components, and alignment features for precise positioning. This multi-functionality reduces the need for additional specialized components, simplifying the overall device structure despite the three-dimensional configuration.

AI summary
An embodiment of an electronic component includes a circuit element disposed within a package, which includes a surface and at least one standoff protruding from the surface. For example, where the circuit element is an inductor in a power supply, the standoff may allow one to mount the inductor component over another component, such as a transistor component. Therefore, the layout area of such a power supply may be smaller than the layout area of a power supply in which the inductor and transistor components are mounted side by side.
