Power Cable Distributor for Fixed-Depth Subrack Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power supply systems for high power equipment require multiple power modules and cables, leading to a complex and costly setup with limited adaptability to different equipment depths, making it difficult to connect power input cables and increasing production costs due to the need for custom dimensions.
Innovation Solution
A power supply system comprising a power supply subrack (PSS) and a power cable distributor (PCD) that allows for a fixed-dimension PSS to fit various depths by using a PCD to introduce and distribute electrical signals to multiple power modules, reducing the number of cables needed and enabling easy connection, while also allowing voltage transformation for adaptability to different power inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple power modules and power input cables are directly connected to meet high power supply demand, then the power supply capability is improved, but the cable management complexity and connection difficulty increase
Solution Approach 1:
The patent merges multiple power input cables into a single bundled cable assembly that connects to the power supply subrack through a unified interface. This combining approach maintains the high power supply capability of multiple cables while significantly reducing cable management complexity and connection difficulty at the subrack level.
Solution Approach 2:
The patent introduces a cable management component as an intermediary between the multiple power input cables and the power supply subrack. This intermediary organizes and routes the multiple cables in a structured manner, simplifying the connection process and reducing management complexity while preserving the high power capability.
2Ease of manufacture
If fixed-dimension power supply subrack is used, then manufacturing cost and production efficiency are improved, but adaptability to different equipment depths deteriorates
Solution Approach 1:
The patent incorporates adjustable or extendable components in the cable management system that can adapt to different equipment depths. This dynamic adjustment capability allows the fixed-dimension subrack to work with various equipment configurations, maintaining production efficiency while improving adaptability.
Solution Approach 2:
The patent designs the cable management component with multi-functional capabilities that enable it to accommodate different equipment depths and configurations. This universal design allows a single fixed-dimension subrack model to be used across multiple applications, simultaneously achieving production efficiency and adaptability.
3Ease of manufacture
If power input sockets are located far from the rear end surface due to depth mismatch, then fixed-dimension subrack can be used, but ease of connection deteriorates
Solution Approach 1:
The patent extends the cable management functionality into the depth dimension by incorporating cable routing channels and extension mechanisms. This dimensional approach allows power input sockets to remain accessible at the rear end surface even when the subrack is positioned deeper in the equipment, maintaining ease of connection while using standardized fixed-dimension subracks.
