High Voltage Transformer Arrangement for Medical Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-voltage transformers in medical imaging devices, such as X-ray tubes, face issues with bulkiness due to heat dissipation requirements and mechanical stress on electrical connectors, leading to potential failure.
Innovation Solution
A high voltage transformer arrangement with a first core in the tank assembly and a second core positioned outside, connected through a primary winding that receives power from an external source, eliminating the need for physical or electrical connections and thus reducing complexity and vulnerability to corrosion and mechanical stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical connectors are used to connect power sources to the HV transformer, then power can be transmitted to the transformer, but the connectors are subject to vibration, corrosion and mechanical stress leading to potential failure
Solution Approach 1:
The patent extracts and removes the vulnerable electrical connectors from the system by using magnetic coupling between the first core (inside tank) and second core (outside tank). This eliminates the physical connection that was susceptible to corrosion, vibration, and mechanical stress, while maintaining power transmission capability through electromagnetic induction.
2Loss of energy
If cooling arrangements are added to dissipate heat from the HV transformer, then heat loss is reduced, but the transformer assembly becomes bulkier
Solution Approach 1:
The patent segments the transformer into two separate cores positioned at a distance from each other. The first core remains inside the compact tank assembly while the second core is positioned outside. This segmentation allows the internal assembly to maintain compact dimensions without requiring extensive cooling arrangements inside the tank, as the external positioning of the second core distributes the thermal management requirements.
3Volume of stationary object
If the HV transformer is made compact, then the assembly size is reduced, but heat dissipation becomes difficult requiring additional cooling arrangements
Solution Approach 1:
The patent resolves the heat dissipation issue by transitioning from a compact internal arrangement to a spatially distributed configuration. By positioning the second core outside the tank at a predefined distance, the system utilizes the external space for thermal management, allowing heat dissipation without increasing the internal tank volume. The magnetic coupling maintains functional integration while enabling separate thermal zones.
