Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple power switch units are used for polarity control, then the control capability is improved, but the system cost increases and stability decreases
Solution Approach 1:
The patent combines multiple power switch units into a single power switch unit that can handle both positive and negative voltage polarity control. The power switch unit is connected to both the first transformer (producing positive voltage) and the second transformer (producing negative voltage), allowing one switch to control both polarity outputs instead of requiring separate switches for each transformer.
Solution Approach 2:
The single power switch unit performs multiple functions: it controls the polarity of both positive and negative voltages, replaces what would traditionally require two separate switch units, and maintains control over electron flow in the X-ray tube. This multi-functional design reduces component count while preserving full control capability.

3Reliability
If a single power switch unit is used to control both transformers, then the system cost and stability are improved, but the control complexity increases
Solution Approach 1:
The patent introduces a control circuit as an intermediary between the power switch unit and the transformers. The control circuit receives control signals and generates appropriate driving signals to control the power switch unit, which in turn controls both transformers. This intermediary layer simplifies the overall control architecture by centralizing the control logic in a dedicated control circuit rather than requiring complex direct control of multiple switches.
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
This configuration reduces system costs and enhances stability by using a single power switch unit to switch between negative and positive voltages, effectively controlling electron flow in the X-ray tube.
Implementation Method 1
the first transformer is configured to receive a first AC voltage and convert the first AC voltage to produce a positive voltage and a driving voltage
Implementation Method 2
the second transformer is configured to receive a second AC voltage and convert the second AC voltage to produce a negative voltage
Implementation Method 3
The produced low voltage is applied between two terminals of the filament so that the filament can provide sufficient electrons by thermionic radiation

AI summary
A power system with a power apparatus for an X-ray tube is disclosed. The power system includes an X-ray tube and a power apparatus for the X-ray tube. The X-ray tube has a cathode and an anode. The power apparatus includes a first power conversion unit, a second power conversion unit, and a power switch unit. The first power conversion unit produces a positive voltage and a driving voltage and the second conversion unit produces a negative. When the power switch unit is turned off by the driving voltage, the power apparatus outputs the negative voltage to suppress electron flow energy generated from the cathode of the X-ray tube, whereas the power apparatus outputs the positive voltage to provide electron flow energy to the anode of the X-ray tube when the power switch unit is turned on by the driving voltage, thus producing X-ray.
