Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RF and microwave printed circuit boards are limited by their planar fabrication design, which restricts layout density and requires increased surface area to accommodate more components, and the layers are used solely for routing signal lines in a constant horizontal plane, limiting their functionality.
Innovation Solution
A printed circuit board design featuring a non-planar structure with layers extending perpendicular to the surfaces, allowing for both surface-mounted and embedded sub-circuits, with electrically isolated surface portions and layers, enabling increased layout density and electromagnetic isolation of embedded sub-circuits from surface components.

Engineering Contradiction Analysis
1Quantity of substance
If planar fabrication design is used, then manufacturing simplicity is maintained, but layout density is limited
Solution Approach 1:
The patent transitions from planar 2D circuit layout to 3D vertical integration by extending layers perpendicular to the board surface. Circuit channels are formed by extending conductive layers vertically through multiple layers, allowing components to be arranged in three dimensions rather than confined to a single plane, thereby increasing layout density without proportionally increasing board footprint.
Solution Approach 2:
The patent embeds circuit channels within the internal structure of the PCB by forming conductive pathways that extend through multiple layers. The circuit channels are nested within the layered structure, with conductive material extending vertically through dielectric layers, effectively nesting functional circuits within the board's internal architecture rather than only on surface planes.
2Adaptability or versatility
If layers are used solely for routing signal lines in constant horizontal plane, then routing simplicity is maintained, but functionality is limited
Solution Approach 1:
The patent enables layers to serve multiple functions simultaneously. Conductive layers are configured to perform both traditional routing functions (signal, power, ground) and create vertical circuit channels. The same layer structure provides both horizontal signal distribution and vertical circuit formation, allowing a single layer to fulfill multiple electrical functions that previously would have required separate structures.
Solution Approach 2:
The patent divides the layer structure into distinct functional regions. Individual layers are segmented to form separate circuit channels, with each layer's conductive material configured to create specific vertical pathways. This segmentation allows different layers to host different circuit functions, enabling independent design and optimization of each circuit channel while maintaining overall system integration.
3Quantity of substance
If all electrical components are formed on exterior surface regions, then manufacturing simplicity is maintained, but layout density is limited
Solution Approach 1:
The patent moves component placement from 2D surface mounting to 3D vertical arrangement. Circuit channels extend vertically through multiple layers, allowing components to be positioned at different heights and depths within the board structure. This vertical dimension provides additional space for component placement without increasing the board's footprint, effectively increasing component capacity within the same surface area.
Solution Approach 2:
The patent nests circuit channels and components within the internal layered structure of the PCB. Rather than placing all components on the exterior surfaces, the design embeds functional circuits within the board's internal architecture, nesting multiple circuit channels within the layered structure. This nesting approach increases component capacity by utilizing the board's internal volume rather than only surface area.
