Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a CT device is powered by the power grid, then it can operate with stable power supply, but it cannot be used in extreme environments or mobile applications where power grid is unavailable
Solution Approach 1:
The power supply system is segmented into multiple independent power sources: power grid interface, energy storage module, and generator interface. This segmentation allows the CT device to operate independently of the power grid by using the energy storage module as a self-contained power source, thereby expanding adaptability to extreme environments and mobile applications while maintaining operational reliability.
Solution Approach 2:
An energy storage module is introduced as an intermediary between the power grid and the CT device. This intermediary can store energy when the power grid is available and supply power when it is not, enabling the CT device to operate in environments without power grid access while maintaining stable power supply for critical operations.
2Adaptability or versatility
If a CT device is designed for mobile use, then it can be deployed to disaster relief sites, but it requires independent power supply systems
Solution Approach 1:
The power supply system is designed with multi-functionality to serve both fixed and mobile applications. The energy storage module can be charged from the power grid when available or from external generators, and can supply power for both stationary operations and mobile deployments. This universal design reduces overall system complexity by using a single integrated power architecture rather than separate systems for different application scenarios.
Solution Approach 2:
The power supply system incorporates dynamic switching capability that can adapt between different power sources (power grid, energy storage module, generator) based on operational requirements. This dynamic configuration allows the system to optimize its structure for mobile operations when needed while maintaining simplicity for fixed installations, thereby reducing overall device complexity across different use cases.

AI summary
A computed tomography (CT) device with an energy storage system includes an energy storage system, a scanning gantry, a diagnostic couch and a console. The energy storage system is respectively connected to the scanning gantry, the diagnostic couch and the console, and can supply power for the scanning gantry, the diagnostic couch and the console. The energy storage system comprises a charging part, an energy storage module and an output part. The scanning gantry comprises a rotor portion and a stator portion. The CT device uses the energy storage system to supply power to the whole CT device, uses a direct current (DC)-alternating current (AC) inverter to convert a DC of the energy storage system into an AC for power supply, and uses a DC-DC converter to convert a voltage of the energy storage system into different voltages for power supply.
