Separated Server Back Plane for Hot-Swappable Control Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current server rack designs require shutting down the power supply and disrupting critical components like cooling fans when the back plane fails, leading to costly downtime and potential data loss, as the single back plane handles both strong and weak components.
Innovation Solution
A separated back plane design featuring a base plane board with strong components and a control module board with weak components, allowing the base plane to continue operating and powering essential components like fans without shutting down, enabling hot-swappable replacement of the control module board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single back plane board is used to manage all components, then the device complexity is reduced and ease of manufacture is improved, but reliability deteriorates because the entire system must shut down when any component fails
Solution Approach 1:
The back plane is segmented into a base plane board containing strong electrical components and a separate control module board containing weak components. This segmentation allows the control module to be replaced without shutting down the base plane, thereby improving reliability while maintaining manufacturing simplicity through modular assembly
2Ease of repair
If the back plane is designed to be replaceable, then ease of repair is improved, but loss of time increases because the entire server must shut down for replacement
Solution Approach 1:
The back plane is divided into replaceable modules where only the control module board needs to be replaced during maintenance, while the base plane board remains operational. This segmentation enables hot-swapping the control module without shutting down the entire server, reducing loss of time while maintaining ease of repair
Solution Approach 2:
The base plane board continues to power and operate critical components like fan modules during control module replacement. This continuity of useful action ensures the server remains operational during maintenance, minimizing downtime and loss of time
3Use of energy by moving object
If the back plane powers all components including fans, then use of energy is optimized, but object-affected harmful factors worsen because fans cannot cool during back plane replacement
Solution Approach 1:
The power distribution is segmented such that the base plane board maintains independent power supply to critical components like fan modules. This segmentation ensures fans continue cooling during control module replacement, preventing overheating damage while optimizing energy use by maintaining only essential power delivery

AI summary
A separated back plane design within a server rack is provided which allows for the hot-swapping of a control module board. The separated back plane design consists of a base plane board and a control module board which connects to the base plane board. The base plane board can draw power from a power supply and can connect a number of electrical components which are not significantly susceptible to damage or failure. The control module board can consist of a number of other electrical components, which are susceptible to damage or failure. The control module board connects to the base plane board, and can be removed during failure of the control module board. When the control module board is removed from the base plane board, the base plane board and its functions continue to operate, and power need not be shut off in order to replace the control module board.
