Solution Overview

Problem

Server chassis designs face challenges with load capacity and structural deformation due to unsupported areas between server trays, leading to reduced load-bearing capacity and potential damage to lower components during high-density server stacking.

Innovation Solution

A server chassis with a three-dimensional reinforcing pattern on the bottom plate, featuring chain-type serial texture groups and embossed patterns, is integrated into the design to enhance structural strength and prevent deformation, with the pattern covering at least 10% of the loading surface area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple servers are stacked in high-density configuration, then the space utilization is improved, but the load-bearing capacity of the tray is reduced causing bending deformation

Engineering Contradiction:

Improvespace utilizationVSAvoidload-bearing capacity

Core Design Contradiction:

ProductivityVSStrength

Solution Approach 1:

The patent applies three-dimensional reinforcing patterns (convex hulls, embossed patterns, and textured surfaces) on the bottom plate to add structural strength without increasing the horizontal footprint. This dimensional transformation from 2D flat surface to 3D reinforced structure enables high-density server stacking while preventing tray bending deformation under heavy loads

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the tray area between support sides is increased, then the ease of operation is improved, but the structural stability deteriorates leading to downward recession

Engineering Contradiction:

Improveease of pullingVSAvoidstructural stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent implements localized reinforcing patterns at critical areas of the bottom plate, including convex hulls at corners and embossed patterns along stress paths. This local quality enhancement provides targeted structural support to prevent downward recession in unsupported areas while maintaining overall tray smoothness for easy operation

Inventive Principle:

Principle #3Local quality

3Strength

If the bottom plate thickness is increased, then the strength is improved, but the device complexity increases

Engineering Contradiction:

Improvestructural strengthVSAvoidstructural complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent segments the bottom plate structure into multiple functional zones: convex hulls at corners for point-load support, embossed patterns in intermediate areas for distributed load resistance, and textured surfaces for overall reinforcement. This segmentation provides comprehensive strength enhancement while maintaining a relatively simple single-plate design without additional components

Inventive Principle:

Principle #1Segmentation

AI summary

A server chassis includes a housing and two support portions. A bottom plate of the housing includes a loading surface and a three-dimensional reinforcing pattern integrally formed on the loading surface for reinforcing the structural strength of the bottom plate. The support portions are respectively located on an outer surface of the sidewall of the housing. A coverage area of the three-dimensional reinforcing pattern is greater than 10% of the total area of the loading surface. The three-dimensional reinforcing pattern includes a plurality of texture patterns regularly reproduced on the loading surface toward a linear axial direction. The three-dimensional reinforcing pattern also includes a plurality of first arc portions and a plurality of second arc portions arranged in a staggered alignment.
