Miniaturized Voltage-Transforming Device 3D Stacked Circuit Boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic circuit devices are limited by their two-dimensional structure, which restricts miniaturization and compactness, as enlarging the circuit board is the only way to accommodate additional components, leading to increased overall volume.
Innovation Solution
A miniaturized voltage-transforming device is achieved by integrating circuit boards and a transformer into a three-dimensional structure, with primary and secondary pins connecting the transformer to parallel and separated circuit boards, allowing for additional components to be installed without increasing volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the circuit board is enlarged to accommodate additional electronic components, then the available installation space is increased, but the overall volume of the whole assembly is increased
Solution Approach 1:
The patent transitions from a two-dimensional planar circuit board layout to a three-dimensional structure by stacking multiple circuit boards vertically and using transformers with pins extending in multiple directions. This dimensional change allows components to be arranged in the vertical dimension (height) rather than only in the horizontal plane, thereby increasing installation space without proportionally increasing overall volume.
Solution Approach 2:
The patent employs a nested arrangement where transformers are positioned between stacked circuit boards, with primary-side pins connecting to one circuit board and secondary-side pins connecting to another. This nesting of components in vertical layers allows multiple functional elements to occupy overlapping or adjacent spatial zones, maximizing space utilization without linearly increasing volume.
2Quantity of substance
If the circuit board is enlarged to accommodate additional electronic components, then more components can be installed, but the miniaturization trend is compromised
Solution Approach 1:
By utilizing the vertical dimension through stacked circuit boards and multi-directional pin extensions, the patent enables installation of additional components (increasing quantity) without requiring proportional increases in horizontal area or overall volume, thus supporting miniaturization while accommodating more components.
Solution Approach 2:
The patent divides the single circuit board into multiple separate circuit boards stacked vertically, with transformers positioned between them. This segmentation allows each board to be optimized for specific functions and enables three-dimensional component placement, increasing component capacity without volume penalty.
