Solution Overview

Problem

Conventional detachable carrier and casing assemblies in server or computer host require time-consuming and cumbersome installation and removal processes, especially with limited internal space, making it difficult to use additional hand tools effectively.

Innovation Solution

A casing assembly with a carrier casing and operation mechanism featuring a plate portion, mount portions, an elastic arm portion, and a blocking portion that can selectively block or release an installation pin, allowing for easy installation and removal without additional tools by switching the blocking portion's position relative to the mount portion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If screws or bolts are used for fixation, then the connection strength is improved, but the installation and removal processes become time-consuming and troublesome

Engineering Contradiction:
Improveconnection strengthVSAvoidinstallation and removal time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The blocking portion is designed to be movable between a blocking position (where it engages with the installation pin to prevent removal) and a non-blocking position (where it allows installation or removal). This dynamic positioning enables quick installation and removal without requiring tools, while still providing secure connection when blocked.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic arm portion automatically returns to its blocking position after the installation pin passes through during installation, and automatically moves to non-blocking position when the pin engages. This self-actuating mechanism eliminates the need for manual operation or additional tools, making the system self-servicing.

Inventive Principle:
Principle #25Self-service

2Reliability

If conventional fixation methods are used, then the connection reliability is improved, but the ease of operation deteriorates due to limited internal space

Engineering Contradiction:
Improveconnection reliabilityVSAvoidease of installation and removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The operation mechanism (blocking portion and elastic arm) is extracted from the traditional screw/bolt fixation system and integrated directly into the carrier casing. This allows the blocking function to be performed by the casing itself without requiring external hand tools, improving ease of operation in limited spaces while maintaining connection reliability through the blocking portion's engagement with the installation pin.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If additional hand tools are used for installation and removal, then the fixation security is improved, but the device complexity increases

Engineering Contradiction:
Improvefixation securityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The blocking function, elastic recovery function, and positioning function are merged into a single integrated operation mechanism consisting of the blocking portion and elastic arm portion. This unified mechanism is built into the carrier casing, eliminating the need for separate hand tools and reducing overall device complexity while maintaining fixation security through the blocking portion's engagement with the installation pin.

Inventive Principle:
Principle #5Merging (Combining)
