Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transformers face challenges in reducing their height without increasing the size of the magnetic core or requiring large holes on the circuit board, and lack adjustable mechanisms for user modification.
Innovation Solution
A transformer design featuring a winding module, two magnetic core modules, and supporting bulges that allow the height to be adjusted by tuning the embedded depth of the bulges and their height, enabling the winding pillar to be placed in a smaller receiving hole on the circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the winding module is disposed in a hole on the circuit board to reduce height, then the height is reduced, but the hole takes a large area of the circuit board
Solution Approach 1:
The winding module is nested within the magnetic core structure, where the winding pillar passes through the receiving hole and the winding baseboard is positioned within the space defined by the magnetic core modules. This nesting arrangement allows the winding module to be integrated into the magnetic core's footprint, reducing the required hole area on the circuit board while maintaining compact height
Solution Approach 2:
The invention transitions from a planar arrangement to a three-dimensional integrated structure by positioning the winding module vertically within the magnetic core modules. The winding pillar extends through the receiving hole and the winding baseboard is positioned at a height controlled by supporting bulges, utilizing vertical space to reduce the horizontal footprint on the circuit board
2Length of moving object
If the height of the transformer is reduced, then space efficiency is improved, but the ability to adjust and maintain height is lost
Solution Approach 1:
The supporting bulges provide adjustable height control by varying their embedded depth in the embedding holes. The embedded depth of the supporting bulges can be tuned to adjust the height of the winding baseboard relative to the circuit board, enabling dynamic adaptation of the transformer's overall height while maintaining a compact form factor
Solution Approach 2:
The height of the transformer is adjusted by changing the embedded depth parameter of the supporting bulges. By modifying the embedded depth, the position of the winding baseboard is changed, thereby adjusting the overall height of the transformer without altering other structural parameters. This allows flexible height adaptation while maintaining space efficiency
3Reliability
If the magnetic core height is increased to accommodate the winding module, then the winding module can be properly held, but the total height of the transformer increases
Solution Approach 1:
The winding module is nested within the magnetic core structure, with the winding pillar passing through the magnetic core and the winding baseboard positioned within the space defined by the magnetic core modules. This nesting allows the magnetic core to provide reliable holding capability while maintaining a compact overall height
Solution Approach 2:
The supporting bulges provide dynamic height adjustment capability, allowing the winding baseboard to be positioned at the optimal height for reliable holding by the magnetic core without unnecessarily increasing the total transformer height. The embedded depth of the supporting bulges can be tuned to achieve the precise height needed for reliable magnetic core engagement
