X-Ray Inspection Power Layout for Smaller UPS Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing X-ray inspection apparatuses face issues with increased size and power requirements of uninterruptible power supplies (UPS) due to the need to supply power to both the processing unit and the X-ray source during external power failures, leading to potential instability and increased size of the UPS.
Innovation Solution
The X-ray inspection apparatus is designed such that the uninterruptible power supply is only connected to the processing unit, ensuring power is supplied during failures while avoiding connection to the X-ray source, thus preventing unnecessary power supply and size increase of the UPS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the uninterruptible power supply is connected to both the processing unit and the X-ray source to ensure continuous operation during power failures, then the reliability of the inspection system is improved, but the size and power capacity of the uninterruptible power supply increases
Solution Approach 1:
The patent divides the power supply system into two separate paths: the uninterruptible power supply is connected only to the control unit and detection unit, while the X-ray source operates independently on external power. This segmentation allows the UPS to be smaller while still providing critical power to the components needed for safe shutdown and data preservation during power failures.
Solution Approach 2:
The patent extracts the X-ray source from the uninterruptible power supply system, removing it from the protected components. This extraction allows the UPS to be sized for only the essential control and detection functions, significantly reducing its size while maintaining reliability for critical operations.
2Productivity
If the uninterruptible power supply is connected to the X-ray source to prevent operation interruption during power failures, then the productivity is improved, but the power consumption and size of the uninterruptible power supply increases
Solution Approach 1:
The patent segments the power consumption responsibilities by assigning the high-power X-ray source to external power supply only, while the low-power control and detection units are covered by the uninterruptible power supply. This segmentation dramatically reduces the power capacity requirements of the UPS.
Solution Approach 2:
The patent extracts the X-ray source from the uninterruptible power supply system, removing the largest power consumer from the UPS load. This extraction allows the system to maintain productivity through safe shutdown procedures while keeping UPS power consumption and size manageable.
