Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rapid switching of output tube voltages is implemented in single-source multi-energy structure, then multi-energy imaging capability is achieved, but tube current fluctuations occur and imaging quality deteriorates
Solution Approach 1:
The patent divides the single X-ray source into multiple independent tanks (first tank, second tank, etc.), each capable of operating at different voltages simultaneously. This segmentation eliminates the need for rapid voltage switching while achieving multi-energy imaging capability, as each tank maintains stable independent operation.
Solution Approach 2:
The system dynamically selects which tanks to activate based on imaging requirements. For dual-energy imaging, two tanks operate simultaneously at different voltages; for single-energy, one tank is activated. This dynamic configuration allows the system to adapt to different imaging needs without the instability caused by rapid switching.
2Reliability
If multiple independent X-ray sources are used for dual-energy or multi-energy control, then precise and stable control is achieved, but equipment costs and overall volume significantly increase
Solution Approach 1:
Multiple tanks are integrated into a single X-ray source assembly with shared components including the housing, rotation mechanism, and detection system. This merging approach maintains the control precision of multiple independent sources while significantly reducing equipment volume and complexity compared to completely separate multi-source systems.
Solution Approach 2:
Each tank is designed as a multi-functional unit that can operate independently or in combination with other tanks. The universal design allows the same physical infrastructure to support single-energy, dual-energy, and multi-energy imaging modes, reducing overall system complexity while maintaining control precision.
