Solution Overview

Problem

In data processing centers, the fixed position of power supplies limits the space and depth of electronic equipment, restricting the use of shelves with different power architectures and depths, and complicates the assembly process.

Innovation Solution

A selectively positionable power connector that can move between two positions, allowing it to align with a power source when in use and retract within a chassis when inserting the chassis between rails, avoiding interference with the power supply busbar and accommodating various power architectures and depths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the power supply is located along the rear face of the shelves, then power can be provided to the electronic equipment, but the space available on the rear face of the electronic equipment is limited and the depth of the shelves is restricted

Engineering Contradiction:
Improvepower supply capabilityVSAvoidspace availability
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The power connector is made movable between a first position (extended beyond the outer casing to engage with the power source) and a second position (retracted within the outer casing). This dynamic positioning allows the connector to provide power when needed while minimizing space occupation during chassis insertion, resolving the contradiction between power supply capability and space availability.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the power connector is fixed in position, then power connection is stable, but the chassis cannot be properly inserted between the rails due to interference with the power supply busbar

Engineering Contradiction:
Improveconnection stabilityVSAvoidassembly process
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The power connector is positioned in the retracted second position before the chassis is inserted between the rails, allowing smooth insertion without interference. After the chassis is properly positioned, the power connector is moved to the extended first position to establish the power connection. This preliminary positioning action resolves the contradiction between connection stability and assembly ease.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the power connector extends beyond the chassis, then power connection is achieved, but the chassis width exceeds the rack assembly width and prevents insertion

Engineering Contradiction:
Improvepower connectionVSAvoidchassis width
Core Design Contradiction:
ReliabilityVSLength of moving object

Solution Approach 1:

The power connector's ability to move between extended and retracted positions allows it to be retracted during chassis insertion (when width is critical) and extended after insertion (when power connection is needed). This dynamic adjustment resolves the contradiction between achieving power connection and maintaining compatible chassis width for rack insertion.

Inventive Principle:
Principle #15Dynamics

AI summary

An electronic system includes a rack assembly including a first rail and a second rail defining a first width therebetween and a chassis that supports electronic components and is insertable between the first rail and the second rail. The chassis includes a first side and a second side defining a second width therebetween that is less than the first width. The electronic system further includes a power connector coupled to the chassis and movable between a first position and a second position. The power connector and the second side define a third width when the power connector is in the first position. The power connector and the second side define a fourth width when the power connector is in the second position. The third width is greater than the first width and the fourth width is less than the first width.
