Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If an external UPS system is utilized to meet the peak power needs of the CT system, then the peak power requirement is satisfied, but the system occupies large amounts of space and incurs high costs

Engineering Contradiction:

Solution Approach 1:

The patent combines the UPS functionality and peak power shaving capability into the internal power distribution unit of the CT system. The energy storage component (batteries) is integrated within the stationary portion of the CT scanner, eliminating the need for separate external UPS systems. This merging reduces space occupation while maintaining the ability to provide peak power during X-ray emission.

Inventive Principle:

Solution Approach 2:

The patent changes the power supply parameter from requiring three-phase power to operating with single-phase power by introducing energy storage components. This parameter change enables deployment in areas without three-phase power infrastructure while maintaining peak power capability through stored energy discharge during high-demand periods.

Inventive Principle:

Solution Approach 1:

The power distribution unit is designed to perform multiple functions: it serves as both the main power distribution system and the UPS system with peak power shaving capability. This multi-functionality reduces the need for separate control systems and simplifies the overall power management architecture despite the added energy storage components.
