Solution Overview

Problem

Conventional slide assemblies for server racks suffer from instability due to the lack of strength in the middle portion of the front support bracket, leading to deformation under heavy loads, which compromises the stability of the entire assembly.

Innovation Solution

A support structure featuring a first support bracket with a bent side portion and extension section, where support members with curved faces are connected to the bracket and engage with the second rail, providing additional support when the rail is pulled, thereby reinforcing the load-bearing capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the middle portion of the front support bracket is designed without additional support structures, then the device complexity is reduced, but the strength and stability of the bracket deteriorate under heavy loads

Engineering Contradiction:
Improvestructure complexityVSAvoidbracket strength
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The support bracket is divided into multiple functional sections: a connection section for attaching to the rail, an extension section that defines a path, and support portions with support members. This segmentation allows each part to perform its specific function optimally while maintaining overall structural integrity under load.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Support members with curved faces are introduced as intermediary elements between the support bracket and the second rail. These support members act as mediators that transfer and distribute loads, providing additional strength to the middle portion of the bracket without requiring a complete redesign of the bracket structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If support members are added to the front support bracket, then the load-bearing capacity is improved, but the device complexity increases

Engineering Contradiction:
Improveload-bearing capacityVSAvoidnumber of components
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The support members are integrated with the extension section of the support bracket, forming a unified structural element. This merging reduces the number of separate components and simplifies the assembly process while still providing the necessary load-bearing enhancement to the middle portion of the bracket.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If the support bracket structure is simplified, then the ease of manufacture is improved, but the stability of the slide assembly deteriorates under heavy loads

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidassembly stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

Additional support structures are applied locally to the middle portion of the support bracket where loads are most critical, rather than reinforcing the entire bracket uniformly. This localized approach enhances stability under heavy loads while minimizing the impact on manufacturing complexity and maintaining ease of production for the majority of the bracket structure.

Inventive Principle:
Principle #3Local quality

AI summary

A support structure for support bracket and rail includes a first rail (10), a second rail (16), a first support bracket (12) and a support member (50). The second rail (16) is slidably connected to the first rail (10) and has two second sidewalls (44) and a second lateral wall (46) which is connected between the two second sidewalls (44). The first support bracket (12) is connected to the first rail (10) and has two support portions (32) between which a path (34) is defined. The support member (50) is connected to one of the support portions (32) of the first support bracket (12) and located corresponding to one of the second sidewalls (44) of the second rail (16). When the second rail (16) is pulled to a position in the path (34) of the first support bracket (12) and contacts the support member (50), the support member (50) supports the second rail (16).
