Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate high-voltage connector systems and heating transformers are used, then maintenance and production flexibility are improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent combines the high-voltage connector system, heating transformer, and radiation protection components into a single integrated high-voltage component assembly. This merging eliminates the need for separate connector systems and individual transformer units, thereby reducing device complexity and installation difficulty while preserving maintenance flexibility through modular replacement of the entire integrated unit.
Solution Approach 2:
The integrated high-voltage component serves multiple functions simultaneously: it provides high-voltage connection, heating current generation through the built-in transformer, radiation protection, and thermal management. This multi-functionality consolidates what would otherwise require separate components, reducing overall system complexity while maintaining the adaptability needed for maintenance and production flexibility.
2Object-affected harmful factors
If circulating insulating medium is used, then radiation protection and electrical insulation are improved, but risk of leakage and operational hazards increase
Solution Approach 1:
The patent employs a nested structure where the vacuum housing containing the x-ray tube is positioned inside the high-voltage component filled with insulating medium. This nested arrangement provides multiple layers of containment: the vacuum seal prevents insulating medium leakage, while the outer high-voltage component provides radiation protection. This hierarchical nesting enhances reliability by isolating the insulating medium within the vacuum seal, eliminating leakage risks while maintaining radiation shielding effectiveness.
Solution Approach 2:
The integrated high-voltage component is designed as a replaceable modular unit. If any component within the integration fails or if leakage is detected, the entire high-voltage component can be quickly replaced as a single unit rather than attempting to repair or replace individual internal components. This approach enhances reliability by providing a fail-safe replacement mechanism while maintaining radiation protection through the integrated design.
3Volume of stationary object
If integrated high-voltage component is used, then volume and installation space are reduced, but heat dissipation challenges increase
Solution Approach 1:
The patent utilizes the circulating insulating medium as a thermal management system. The insulating medium flows through channels within the integrated high-voltage component, absorbing heat generated by the heating transformer and x-ray tube, and transporting it to external heat exchangers. This hydraulic thermal management system enables effective heat dissipation from the compact integrated component without requiring additional cooling infrastructure, thus maintaining reduced volume while solving heat dissipation challenges.
Solution Approach 2:
The high-voltage component housing is constructed from composite materials that provide both electrical insulation and thermal management properties. The housing material is designed to conduct heat away from critical components while maintaining electrical insulation integrity, enabling the compact integrated design to effectively manage thermal loads without increasing volume or compromising insulation performance.
