Rotary Flap Door for Server Heat Dissipation

Solution Overview

Problem

Different data storage components in industrial and server computers have varying sizes, leading to uneven space arrangements that cause heat dissipating turbulence and inefficiency within the devices.

Innovation Solution

A rotary flap door device with a base plate and door member that can rotate to accommodate both smaller and larger data storage components, defining a flow channel or overlaying on the base plate to optimize heat dissipation by concentrating or redirecting thermal airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different sized data storage components are installed inside the casing, then the device can accommodate various storage needs, but it causes uneven space arrangement and heat dissipating turbulence

Engineering Contradiction:

Improveaccommodation of different data storage component sizesVSAvoidheat dissipating turbulence

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The door body is designed to be rotatable relative to the base plate, allowing it to dynamically change its position between a first position (when data storage component length L1 is detected) and a second position (when data storage component length L2 is detected). This dynamic adjustment enables the door body to adapt to different component sizes while maintaining proper airflow paths, thereby resolving the contradiction between versatility and heat dissipation efficiency.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If a fixed door structure is used, then the manufacturing process is simple, but it cannot adapt to different data storage component sizes

Engineering Contradiction:

Improvesimplicity of door structureVSAvoidadaptability to different component sizes

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The door body is designed to be rotatable relative to the base plate, allowing it to dynamically change its position between a first position (when data storage component length L1 is detected) and a second position (when data storage component length L2 is detected). This dynamic adjustment enables the door body to adapt to different component sizes while maintaining proper airflow paths, thereby resolving the contradiction between versatility and heat dissipation efficiency.

Inventive Principle:

Principle #15Dynamics

3Productivity

If the door body is rotated to the open position for smaller components, then heat dissipation flow is concentrated, but the door body occupies space when not needed

Engineering Contradiction:

Improveheat dissipation efficiencyVSAvoiddoor body space occupation

Core Design Contradiction:

ProductivityVSVolume of moving object

Solution Approach 1:

The door body is designed to be rotatable relative to the base plate, allowing it to dynamically change its position between a first position (when data storage component length L1 is detected) and a second position (when data storage component length L2 is detected). This dynamic adjustment enables the door body to adapt to different component sizes while maintaining proper airflow paths, thereby resolving the contradiction between versatility and heat dissipation efficiency.

AI summary

An electronic device includes a casing and a rotary flap door device. The rotary flap door device is installed inside the casing and includes a base plate and a door member. The base plate is mounted on the casing. A base constraining structure and a base engaging structure are formed on the base plate. The door member includes a door body, a door limit part and a door engaging portion. The door body is rotably disposed on the base plate. The door limit part extends from the door body and is for embedding into the base limit part. The door engaging portion protrudes from the door body and is for engaging with the base engaging portion.
