Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the data center configuration is changed to support additional power supply interfaces, then the power supply capacity and redundancy are improved, but the reconstruction cost and downtime increase
Solution Approach 1:
The power module assembly is designed with multi-functionality to support both 2(n+1) and 2n power supply configurations. The assembly includes (n+1) power modules with 2(n+1) input connectors, where any 2n connectors can be used for power supply. This universal design allows the same hardware to adapt to different configuration requirements without reconstruction, eliminating downtime while maintaining power supply redundancy.
Solution Approach 2:
The power module assembly implements dynamic adaptability by allowing flexible configuration of power supply connections. The system can dynamically adjust to use either 2(n+1) or 2n power supply branches based on available interfaces, enabling the data center to maintain operational flexibility without physical reconstruction or service interruption.
2Reliability
If the data center configuration is changed to support additional power supply interfaces, then the power supply capacity is improved, but the reconstruction cost increases
Solution Approach 1:
The power module assembly employs universality by designing a single configuration that serves multiple purposes. The assembly can operate with either 2(n+1) or 2n power supply branches, eliminating the need for separate hardware configurations. This reduces reconstruction costs while maintaining the ability to provide enhanced power supply capacity and redundancy when interfaces are available.
Solution Approach 2:
The system utilizes parameter changes by adjusting the number of active power supply connections rather than changing physical infrastructure. The power module assembly can transition between operating modes (2n or 2(n+1) branches) by simply configuring which input connectors are connected, avoiding costly physical reconstruction while adapting power supply capacity to available resources.
3Adaptability or versatility
If 2n input connectors are used instead of 2(n+1) input connectors, then the number of required interfaces is reduced, but the power supply redundancy is decreased
Solution Approach 1:
The power module assembly segments the power supply interfaces into distinct input connectors, with each connector independently connectable to power supply branches. This segmentation allows flexible configuration where any 2n connectors can be utilized for power supply, enabling interface compatibility with existing data centers while maintaining the ability to achieve full redundancy when all 2(n+1) connectors are available.
Solution Approach 2:
The assembly achieves universality by designing power modules that can function with varying numbers of connected interfaces. Each power module can operate with power supplied through different combinations of input connectors, allowing the system to maintain adaptability to existing 2n interface configurations while preserving the capability for enhanced redundancy when 2(n+1) interfaces are available.

AI summary
A power module assembly includes (n+1) power modules and 2(n+1) input connectors, where n is a positive integer. The input connectors are used to connect power supply sources and the power modules. Each power module is connected to two input connectors. Based on positions of the 2(n+1) input connectors, when 2n input connectors among the 2(n+1) input connectors are connected to power supply inputs of the power supply sources and a (2a+1)th input connector and a (2a+2)th input connector among the 2(n+1) input connectors are not connected to the power supply inputs of the power supply sources, the (n+1) power modules in the power module assembly supply power to a load, where a is a non-negative integer, and is less than or equal to n. The power modules may be flexibly compatible with power supply inputs from 2(n+1) or 2n branches.
