Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power conversion devices have a bulky design due to non-centralized component placement, limiting their width reduction and making it difficult to increase output power without increasing size or number of devices.
Innovation Solution
The power conversion device features modularized components perpendicularly mounted on a main board, with specific arrangements that include a connector module, input and output conversion modules, a capacitor, control module, and conducting parts, allowing for a centralized layout and reduced width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are horizontally installed and non-centrally arranged on the main board, then the layout flexibility is improved, but the overall volume and width of the power conversion device become bulky
Solution Approach 1:
The patent transitions from horizontal component arrangement to vertical mounting, utilizing the third dimension (height/thickness) to accommodate components. This dimensional change allows components to be stacked or arranged vertically on the main board, significantly reducing the horizontal footprint and overall width of the power conversion device while maintaining layout flexibility through vertical positioning variations.
Solution Approach 2:
The patent implements centralized arrangement where input and output connectors are positioned adjacent to each other, and components are grouped in concentrated areas. This nesting-like arrangement allows multiple components to occupy overlapping or adjacent spatial zones, reducing the total volume required while maintaining electrical connectivity and functional relationships.
2Device complexity
If input connector and output connector are separately installed on different positions, then the electrical connection simplicity is improved, but the width reduction objective cannot be achieved
Solution Approach 1:
The patent merges the locations of input and output connectors by positioning them adjacent to each other on the main board. This combining of previously separate connector positions into a concentrated area reduces the overall width required for the device while maintaining the electrical connection simplicity through direct routing between the closely positioned connectors.
3Power
If output power of each power conversion device is increased, then the power system output power is improved, but the device width must be increased or more devices are needed
Solution Approach 1:
The patent enables higher output power within the same width by transitioning to vertical component mounting and centralized arrangement. This dimensional reorganization increases power density by utilizing vertical space for heat sinks, larger capacitors, and more efficient component layouts, allowing greater power handling capability without increasing the horizontal footprint of the device.
