Solution Overview
Problem
The installation and positioning of power modules, particularly transformers, within data centers is challenging due to small operating spaces and manufacturing errors, leading to gaps that affect excitation inductance and heat dissipation.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a split type transformer is adopted to reduce volume and improve heat dissipation, then the volume of the transformer is reduced and heat dissipation capability is improved, but the difficulty of fixation and clamping increases due to small operating space inside the chamber
Solution Approach 1:
The compressing member is designed to be movable along the compressing direction, transitioning from a relaxed state to a compressed state. This dynamic structure allows the compressing member to adapt to manufacturing errors and assembly variations, enabling effective fixation and clamping of the split type transformer within the limited chamber space while maintaining the volume reduction and heat dissipation benefits
Solution Approach 2:
The compressing member acts as an intermediary between the fixed plate and the split type transformer. It transmits and adjusts the compressing force to ensure proper fixation, bridging the gap between the static chamber structure and the components that need to be secured, thereby solving the fixation difficulty without compromising the transformer's reduced volume design
2Reliability
If the transformer components are fixed in the insulating housing, then the transformer is secured in position, but gaps exist between the fixed plate and the magnetic core due to manufacturing or assembly errors which affects the excitation inductance value
Solution Approach 1:
The compressing member changes its physical parameters (position, compression force) to compensate for manufacturing and assembly errors. By adjusting the compression degree, the system eliminates gaps between the fixed plate and magnetic core, ensuring proper magnetic coupling and excitation inductance values while maintaining reliable fixation
3Reliability
If insulating material is used to cover the primary and secondary sides of the transformer, then electrical insulation is provided, but the volume increases and heat dissipation becomes difficult due to poor thermal conductivity
Solution Approach 1:
The compressing structure applies localized compression forces at specific contact points between the transformer components and the fixed plate. This localized approach maintains electrical insulation where needed while creating direct thermal contact paths through the compression interfaces, enabling heat dissipation without requiring extensive insulating material coverage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

Implementation Method 1
a fastening bolt passing through the threaded hole of the compressing mechanism housing and abutting on the transmission slanted block; when the fastening bolt is rotated along the first rotation axis, the fastening bolt moves along the extension direction of the first rotation axis to push the transmission slanted block slides along the slope
Implementation Method 2
a transmission slanted block fitting with the slope of the compressing mechanism housing; when the fastening bolt is rotated along the first rotation axis, the fastening bolt moves along the extension direction of the first rotation axis to push the transmission slanted block slides along the slope of the compressing mechanism housing such that the press-fit plate contacts with the side walls of the housing to produce a compressing force
Implementation Method 3
a first spring provided between one end of the long groove and the pin, such that the transmission slanted block is pushed to an initial position
