Bidirectional Power Inlet for Server Rack Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current server rack systems are inefficient for maintenance and inspection, and they do not maximize internal component space, leading to increased costs and time for component installation and replacement.
Innovation Solution
A server rack system with a chassis having opposite openings for easy access, where the motherboard, power-supply, and storage array modules can be independently plugged in and out, and power ports are located for bidirectional access, allowing for flexible installation and maintenance without repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If power cables are arranged to the rear end of the rack and exposed outwards, then the power inlet structure is simple, but maintenance and inspection time increases due to difficult access
Solution Approach 1:
The server device is divided into modular components (motherboard module, power-supply module, storage array module) that can be independently accessed and replaced. The chassis is segmented with multiple openings to allow independent access to different components without disassembling the entire device.
Solution Approach 2:
A power port connector is introduced as an intermediary component that connects the first power port (rear access) and second power port (front access), enabling flexible power cable arrangement from either direction while maintaining electrical connectivity.
2Ease of manufacture
If server components are designed for fixed installation, then manufacturing cost is reduced, but flexibility in mounting and maintenance is limited
Solution Approach 1:
The system transitions from fixed installation to dynamic, flexible positioning. Components are designed to be movable and repositionable within the chassis, with the power port connector enabling power cables to adapt to different component positions without requiring redesign of the entire power distribution system.
Solution Approach 2:
The power port connector serves multiple functions: it connects power ports located at different positions, accommodates various component placements, and enables both front and rear cable access. This universal connector design allows the same component to be installed in multiple positions without requiring position-specific modifications.
3Device complexity
If power ports are located only at the rear of the chassis, then the design is simple, but access during maintenance becomes difficult requiring device repositioning
Solution Approach 1:
The chassis design breaks the traditional symmetric arrangement by providing asymmetric power access: the first power port is located at the rear opening while the second power port is located at the front opening. This asymmetric design allows flexible cable management from either direction, accommodating different installation and maintenance scenarios.
Solution Approach 2:
The power access system transitions from a single-point (rear only) to multi-point access by adding front access capability. The power port connector enables three-dimensional flexibility in cable routing, allowing power cables to access from both front and rear directions, effectively adding another dimension of access freedom.

AI summary
A server device is provided. The server device includes a chassis with a containing space, first and second openings. The first and second openings are located at two opposite ends of the containing space. The chassis includes a motherboard module in the containing space; a power-supply module disposed in the containing space, electrically connected to the motherboard module, and capable of plugging in and out from the chassis via the first opening, wherein the power-supply module comprises a first power port located in the second opening; a power port connector comprising a second power port located in the first opening, and configured to selectively connect to the first power port located in the first opening; and a storage array module, electrically connected to the motherboard module and the power-supply module.
