Solution Overview

Problem

Conventional installation devices for slide assemblies, such as those used for computer servers, require cumbersome manual operation and often necessitate two people to remove heavy equipment, due to the need for resilient plates or swing plates that require manual shifting and protrusions to be moved simultaneously, making the process inconvenient and space-intensive.

Innovation Solution

The proposed installation device features a first rail and a second rail with a positioning member and a release member, where the positioning member has a base, arm board, and end board, and the release member has a reception portion, connection board, and operation portion, allowing for easy engagement and disengagement of the exterior equipment without tools, utilizing a guide hole and protrusion mechanism to facilitate one-person operation and reduce space requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If resilient plate or swing plate is used to contact protrusions on drawer sides, then the drawer can be connected to rails, but the user must use one hand to shift the plate and the other hand to move protrusions, making operation inconvenient

Engineering Contradiction:
Improveconvenience of installing/removing drawerVSAvoidmanual shifting mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The release member combines multiple functions into a single component: it shifts the positioning member, releases the protrusions, and returns to its original position automatically. This merging of functions eliminates the need for separate manual operations on different components, resolving the contradiction between ease of operation and device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The release member is designed to automatically return to its original position after releasing the protrusions, eliminating the need for manual resetting. The system performs part of the operation automatically through the interaction between the release member, positioning member, and rail structure, reducing the manual effort required.

Inventive Principle:
Principle #25Self-service

2Strength

If server is heavy, then it can be securely mounted on rails, but it becomes difficult for one user to separate the server from rails, requiring at least two people

Engineering Contradiction:
Improvemounting securityVSAvoidremoval difficulty
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The positioning member is designed to be movable rather than fixed, allowing it to be shifted from the engaged position (providing strong mounting) to the disengaged position (allowing easy removal). The dynamic nature of the positioning member enables the system to transition between secure mounting and easy removal states, resolving the contradiction between strength and ease of operation.

Inventive Principle:
Principle #15Dynamics

3Length of moving object

If extension between push block and release member is elongate and thin, then it can transmit force, but it may be bent when applied by force

Engineering Contradiction:
Improveextension lengthVSAvoidresistance to bending
Core Design Contradiction:
Length of moving objectVSStrength

Solution Approach 1:

The release member transitions from a linear force transmission component to a rotational component that operates within the hole of the rail. By changing the dimension of operation from linear extension to rotational movement, the design eliminates the need for long thin extensions while maintaining force transmission capability and improving structural strength.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Ease of operation

If positioning member is located remote from inside of inner rail, then protruding bit can be accessed, but larger space is needed

Engineering Contradiction:
Improveaccessibility of protruding bitVSAvoidspace required
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The release member is nested within the hole of the rail, and the positioning member is nested within the rail structure. This nested arrangement allows the components to be accessed and operated within the existing space of the rail, eliminating the need for additional external space while maintaining operational accessibility.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

An installation device for a slide assembly includes a first rail (11) and a second rail (12) which has a guide seat (20) and two slots (22a), (22b) for being connected with an exterior equipment (10). A positioning member (14) is fixed to the second rail (12) and an arm board (26) has a positioning hole (30) located corresponding to one of the slots (22a), (22b) of the second rail (12) so that one of installation members (58), (60) of the exterior equipment (10) is engaged with the positioning hole (30). An end board (28) has a through hole (32) and an end piece (34) extending toward the second rail (12). The release member (16) is movably installed to the second rail (12). When the release member (16) is moved by an exterior force and positioned by the guide seat (20), the protrusion (48) of the release member (16) pushes the end piece (34) to keep the positioning hole (30) away from the second rail (12) and the exterior equipment (10) can be removed from the positioning hole (30).
