Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the high voltage tank assembly is located outside the shield housing and connected to the radiation source using cables, then the radiation generator can be designed with separate high voltage generation and radiation source units, but the connecting means becomes cumbersome and expensive, and radiation leakage may occur
Solution Approach 1:
The patent merges the high voltage tank assembly with the shield housing by integrating the voltage rectifier circuit directly into the housing that contains the radiation source. This eliminates the need for external cables and connecting means, thereby preventing radiation leakage while maintaining the functional separation of high voltage generation and radiation source operation.
2Device complexity
If the high voltage tank assembly is located outside the shield housing, then the radiation generator can have modular design, but the overall size and weight increase due to cumbersome connecting means
Solution Approach 1:
The patent combines the high voltage tank assembly with the shield housing into a single integrated unit. The voltage rectifier circuit is mounted within the housing, eliminating the need for heavy external cables and connecting mechanisms, thereby reducing the overall weight while maintaining modular functionality.
Solution Approach 2:
The patent extracts the voltage rectifier circuit from the traditional external high voltage tank assembly and places it directly within the shield housing. This extraction eliminates the need for heavy connecting cables and reduces the overall weight of the radiation generator while maintaining the essential functions.
3Object-affected harmful factors
If the high voltage tank assembly and radiation source are housed together within the shield housing, then the connecting means is eliminated, but the weight and bulk of the unit become greater than necessary
Solution Approach 1:
The patent segments the shield housing into functional zones: the voltage rectifier circuit is mounted on the inner surface of the housing, while the radiation source is positioned in a separate compartment. This segmentation allows for optimized space utilization and reduced weight compared to traditional designs where the entire high voltage assembly is housed externally with heavy shielding.
Solution Approach 2:
The patent utilizes the three-dimensional space within the shield housing by mounting the voltage rectifier circuit on the inner surface area rather than requiring a separate external housing. This dimensional optimization reduces the overall bulk and weight of the unit while maintaining all necessary functions.
4Power
If traditional voltage rectifier circuits are used, then the high voltage can be delivered to the radiation source, but the assembly becomes bulky and incompatible with mobile diagnostic radiology installations
Solution Approach 1:
The patent merges the voltage rectifier circuit with the shield housing structure, eliminating the need for a separate bulky high voltage tank assembly. The rectifier circuit is integrated directly into the housing, maintaining full high voltage delivery capability while dramatically reducing the overall volume of the assembly for mobile applications.
