Solution Overview

Problem

Conventional casing mounting rail systems are cumbersome and time-consuming to install, especially when multiple blank plates are required to fill empty spaces in racks, leading to issues with electronic device mounting and cooling efficiency due to protrusions and complex alignment processes.

Innovation Solution

A casing mounting rail system that includes a coupling member, a rotatable plate-shaped member, and a fixing mechanism, allowing for easy rotation and automatic positioning to serve as both a mounting rail and a blank plate, reducing the need for separate blank plates and simplifying the installation process by using magnetic attraction and a coil spring mechanism for alignment and support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate blank plates are used to fill empty spaces in racks, then the rack can be completely filled and cooling efficiency is improved, but the installation process becomes complicated and time-consuming

Engineering Contradiction:
Improvecooling efficiencyVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent combines the blank plate and mounting rail into a single integrated structure. The L-shaped mounting rail includes a first plate that functions as a blank plate to fill empty rack spaces and a second plate that serves as the mounting surface for electronic devices. This integration eliminates the need to separately install blank plates and mounting rails, significantly reducing installation time while maintaining complete rack filling for proper cooling.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The L-shaped mounting rail structure serves multiple functions simultaneously: it acts as a blank plate to fill empty spaces, provides a mounting rail for attaching electronic devices, and enables easy installation through a single component. The first plate fills the rack space while the second plate provides the mounting surface, making the structure universal for both filling and mounting purposes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If multiple separate blank plates are installed to fill rack spaces, then complete rack filling is achieved, but the device complexity and installation complexity increase

Engineering Contradiction:
Improverack filling completenessVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the blank plate function and mounting rail function into a single L-shaped structure. The first plate (horizontal portion) serves as the blank plate that fills empty rack spaces, while the second plate (vertical portion) serves as the mounting rail for electronic devices. This single integrated component replaces what would traditionally require separate blank plates and mounting rails, reducing device complexity and installation steps.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If conventional monolithic blank plates are used, then they can fill rack spaces, but they require removal and replacement when mounting electronic devices

Engineering Contradiction:
Improverack space fillingVSAvoidmounting operation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mounting rail is segmented into two functional plates: the first plate serves as the blank plate for filling rack spaces, and the second plate serves as the mounting surface for electronic devices. This segmentation allows the mounting rail to remain in place while providing the mounting function, eliminating the need to remove and replace separate blank plates when installing electronic devices.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The L-shaped mounting rail structure provides universal functionality by simultaneously serving as both the blank plate (first plate) and the mounting rail (second plate). This multi-functionality allows the structure to fill rack spaces and mount electronic devices without requiring separate components, greatly simplifying the mounting operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A coupling member is coupled to a support column of a rack. A plate-shaped member is rotatably engaged with a coupling member with one longitudinal end as an axis. An L-shaped member includes a first flat plate and a second flat plate orthogonal to the first flat plate and includes, with a transverse end of the first flat plate rotatably engaged with one plate face of the plate-shaped member with the longitudinal direction of the plate-shaped member as an axis and with a plate face of the first flat plate in intimate contact with the one plate face, a mounting member in which the second flat plate protrudes from one transverse end of the plate-shaped member and a fixing mechanism that fixes the mounting member with the plate face of the first flat plate in intimate contact with the one plate face of the plate-shaped member.
