Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing X-ray generator systems face issues due to thermal expansion and contraction of insulating liquids, which cause pressure fluctuations that can damage the housing and electronic components, leading to potential deformation and failure.
Innovation Solution
The introduction of a radiation device installation housing with a flange and a compensation device, such as an elastic drum membrane, that allows for thermal expansion and contraction while maintaining a constant pressure environment by deforming within a dedicated space, ensuring the insulating liquid is evenly distributed and preventing excessive pressure on electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing is made sealed and filled with insulating liquid for cooling and insulation, then the cooling effect and insulation performance are improved, but the thermal expansion and contraction of the insulating liquid causes pressure fluctuations that can damage the housing and electronic components
Solution Approach 1:
The patent employs a flexible bladder (elastic drum membrane) inside the housing to absorb the thermal expansion and contraction of the insulating liquid. The bladder is made of elastic material that can deform under pressure changes, expanding when the liquid expands and contracting when the liquid contracts, thereby maintaining constant pressure on the housing walls and protecting electronic components from pressure damage.
Solution Approach 2:
The patent changes the physical state parameters of the system by introducing a compressible gas chamber above the insulating liquid. The gas chamber allows the liquid volume to change with temperature while maintaining constant pressure, as the gas compresses or expands to accommodate the liquid's thermal expansion and contraction without transmitting pressure fluctuations to the housing.
2Volume of moving object
If the housing volume is reduced to make the device more compact, then the device size is reduced, but the insulating liquid may not be evenly distributed and may not fully utilize the housing space
Solution Approach 1:
The patent uses the flexible bladder to automatically adjust the insulating liquid distribution within the housing. As the liquid expands or contracts with temperature changes, the bladder deforms to maintain uniform pressure distribution, ensuring the liquid remains evenly distributed throughout the available space without requiring external control mechanisms.
Solution Approach 2:
The patent introduces a dynamic element (the flexible bladder) that can change its volume and shape in response to thermal expansion and contraction of the insulating liquid. This dynamic adjustment ensures that the liquid remains evenly distributed throughout the housing volume regardless of temperature variations, preventing pooling or void formation.
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 solution effectively stabilizes the pressure within the housing, preventing damage from thermal expansion and contraction, ensuring the X-ray generator operates reliably by maintaining consistent pressure and ensuring the insulating liquid is fully utilized within the housing.
Implementation Method 1
the insulating liquid is heated and expanded (that is called as 'thermal expansion')
Implementation Method 2
the insulating liquid will be cooled and contracted (that is called as 'cold contraction')
Implementation Method 3
an elastic drum membrane which is able to fixedly connect with a port of the flange away from the inner wall of the housing body and cover on the port of the flange away from the inner wall of the housing body, and the elastic drum membrane is able to deform within the compensation device moving space toward the direction away from or close to the insulating liquid
