Solution Overview

Problem

In blade server environments, the need for increased computational power often conflicts with space constraints, making it difficult to rearrange or reconfigure blade servers to optimize space usage.

Innovation Solution

A toolless configuration system for computer enclosures that includes dividers with locking tabs and rotating mechanisms, allowing for easy insertion and locking of dividers between walls to convert between full and half-height blade support, providing flexibility in blade placement and configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If blade servers are densely packed in a computer enclosure to increase computational power, then space utilization is improved, but the ability to rearrange and reconfigure the blade servers deteriorates

Engineering Contradiction:
Improvecomputational power densityVSAvoidreconfigurability
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The enclosure is segmented into multiple bays by removable dividers that can be inserted between blade servers. These dividers create modular sections that can be independently configured, allowing the system to maintain high density while enabling flexible rearrangement of servers within the segmented structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dividers incorporate a locking mechanism with a movable locking tab that transitions between locked and unlocked states. When unlocked, the divider can be removed to reconfigure the enclosure; when locked, it secures the divider in place. This dynamic state change enables the system to switch between stable high-density operation and flexible reconfiguration mode.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If traditional fixed dividers are used in computer enclosures, then structural stability is improved, but ease of reconfiguration deteriorates

Engineering Contradiction:
Improvedivider stabilityVSAvoidreconfiguration ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The locking mechanism is designed to be operated directly by the user without requiring external tools. The locking tab can be manually moved between locked and unlocked positions, and the divider can be removed or repositioned by hand. This toolless design eliminates the need for specialized installation tools while maintaining secure locking when engaged.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If removable dividers are added to enable reconfiguration, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveblade placement flexibilityVSAvoiddivider mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The locking function is extracted as a separate, simple mechanism (the locking tab) that is integrated into the divider structure. This modular approach allows the locking mechanism to be independently designed and optimized, adding reconfiguration capability without significantly complicating the overall divider design. The locking tab can be engaged or disengaged independently from the divider body.

Inventive Principle:
Principle #2Taking out (Extraction)
