Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing motherboard handles in server type information handling systems obstruct airflow, particularly in fan outlets, leading to decreased cooling efficiency, especially with enlarged heatsinks, and fitting both a handle and air baffle in compact spaces is challenging.

Innovation Solution

A multi-function handle component with a multi-surface grasping structure and an air baffle portion that minimizes airflow obstruction, facilitating airflow management while allowing easy manipulation of high performance modules, and is compatible with motherboard specifications without requiring layout changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional motherboard handle is used, then manipulation of the motherboard is facilitated, but airflow obstruction increases and cooling efficiency decreases

Engineering Contradiction:

Improvemanipulation of motherboardVSAvoidairflow obstruction

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The handle is divided into multiple segments including a first portion and a second portion connected by a hinge, allowing the handle to be segmented for flexible positioning and reduced airflow obstruction while maintaining manipulation functionality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The handle incorporates a hinge mechanism that allows it to rotate between different positions, enabling dynamic adjustment to minimize airflow obstruction while still providing ease of manipulation when needed

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the handle size is increased for better grasping, then ease of manipulation improves, but the airflow area is further reduced

Engineering Contradiction:

Improvegrasping capabilityVSAvoidairflow area

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The handle design extends in multiple dimensions with portions arranged to provide grasping surfaces while minimizing projection into the airflow path, utilizing three-dimensional space efficiently to maintain both grasping capability and airflow area

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Object-affected harmful factors

If a separate air baffle is added to manage airflow, then cooling efficiency improves, but device complexity increases

Engineering Contradiction:

Improvecooling efficiencyVSAvoidnumber of components

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The air baffle functionality is merged with the handle structure, where the handle portions themselves serve as airflow management elements, eliminating the need for separate air baffle components and reducing overall device complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The handle is designed to perform multiple functions simultaneously: providing manipulation capability for the motherboard and acting as an airflow management structure, thereby reducing the need for separate dedicated components

Inventive Principle:

Principle #6Universality (Multi-functionality)
