Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the uninterruptible power module is designed as a large integrated unit, then the power supply capacity is sufficient, but the installation and maintenance become difficult and require multiple personnel
Solution Approach 1:
The uninterruptible power module is divided into multiple independent functional modules: rectification module, inverter module, fan module, and control module. Each module can be independently installed, removed, and maintained. The rectification module converts AC to DC, the inverter module converts DC to AC, and the fan module provides cooling, allowing partial replacement without discarding the entire unit.
Solution Approach 2:
The functional modules are nested within a common housing structure that provides integrated support, power distribution, and cooling pathways. The modules fit together like nested components, sharing common mounting structures and electrical connections while maintaining individual replaceability.
2Power
If the uninterruptible power module is designed as a large integrated unit, then the power supply capacity is sufficient, but the volume and weight increase making handling difficult
Solution Approach 1:
The power module system is segmented into smaller functional units that can be separately manufactured and handled. Each module has reduced volume and weight compared to the traditional integrated design, allowing single-person handling while maintaining total system power capacity through modular aggregation.
3Power
If the uninterruptible power module is designed as a large integrated unit, then the power supply capacity is sufficient, but the maintenance complexity increases and time consumption increases
Solution Approach 1:
The system is segmented into functionally independent modules with standardized interfaces. When a fault occurs, the problematic module can be quickly identified and replaced without affecting other modules. The rectification module, inverter module, and fan module can be independently maintained, significantly reducing maintenance time and complexity.
Solution Approach 2:
The modular design enables selective replacement of only the faulty module rather than the entire power supply unit. The replaced module can be recovered, tested, and reused after repair, reducing waste and maintenance costs while preserving system power capacity.
4Adaptability or versatility
If the uninterruptible power module uses non-standard interfaces, then the design flexibility is high, but the assembly and disassembly become complex
Solution Approach 1:
The modules employ standardized mechanical and electrical interfaces that enable universal compatibility across different module types. The standard interfaces simplify assembly and disassembly operations while maintaining design flexibility through the ability to configure different module combinations for various power supply requirements.

AI summary
Uninterruptible power modules for use with uninterruptible power supplies are provides. The uninterruptible power modules include a rectification module, an inverter module and a fan module which are detachably assembled together. The rectification module includes a first housing; a first electrical network, mounted to the first housing, the first electrical network is configured to be selectively connected to a main power supply or current supplied by a standby power supply and convert the current provided by a main power supply or a standby power supply into DC current. The inverter module includes a second housing, detachably connected to the first housing; a second electrical network, which is mounted to the second housing and connected to the first electrical network. The second electrical network is converts DC into AC power. The uninterruptible power module further includes a transfer switch that controls the first electrical network from being connected with the main power supply to being connected with the standby power supply.
