Solution Overview

Problem

Existing rack systems face challenges in accommodating slide rail assemblies within a space of reduced width, necessitating an adaptable fitting assembly that can efficiently utilize available space while ensuring secure mounting and easy detachment.

Innovation Solution

The proposed fitting assembly comprises a pair of fitting devices mounted on opposite sides of a rack, each capable of engaging with the rack's side frames to secure slide rail assemblies within a narrower space than the rack's full width. This assembly includes a locking mechanism for secure attachment and tool-free detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If slide rail assemblies are mounted within a space of reduced width, then adaptability to different market requirements is improved, but the complexity of the mounting structure increases

Engineering Contradiction:
Improveadaptability to different market requirementsVSAvoidcomplexity of the mounting structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fitting assembly is divided into separate fitting devices, each independently mounted to side frames of the rack. Each fitting device can be configured for different width requirements, allowing the system to adapt to various market requirements without redesigning the entire mounting structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fitting devices are designed with universal engaging structures that can be engaged with different mounting features on the rack side frames. The same fitting device configuration can accommodate different width requirements by selecting appropriate mounting feature positions, providing multi-functionality across various applications.

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

2Reliability

If a locking mechanism is used to secure the fitting device, then mounting reliability is improved, but the ease of operation deteriorates due to additional locking steps

Engineering Contradiction:
Improvemounting reliabilityVSAvoidease of detachment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking member is designed to be manually operable without requiring additional tools. The user can directly operate the locking member to engage or disengage the mounting feature, making the system self-servicing for both secure mounting and easy detachment operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The locking member transitions between fixed (locked) and movable (unlocked) states, allowing the fitting device to be securely mounted when locked and easily detached when unlocked. This dynamic state change enables both high reliability during operation and ease of detachment when needed.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the fitting device is designed for tool-free detachment, then ease of operation is improved, but the strength of the connection may be compromised

Engineering Contradiction:
Improveease of detachmentVSAvoidstrength of the connection
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The manual operation of the locking member provides sufficient connection strength when engaged, while allowing easy tool-free detachment when operated. The design achieves both ease of operation and adequate connection strength through the mechanical advantage of the locking member geometry.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The locking member utilizes curved or inclined surfaces to create mechanical advantage, where a small manual force can generate sufficient locking force to maintain a strong connection during operation, while still allowing easy release when the locking member is operated.

Inventive Principle:
Principle #14Spheroidality (Curvature)
