Solution Overview

Problem

Server cabinets with heavy servers are prone to falling due to shifted center of gravity when servers are drawn out, and traditional stabilizing methods like screws are inconvenient on anti-static floors because they are too large and heavy.

Innovation Solution

An anti-falling apparatus comprising a receiving member, an extending arm, a blocking member, and a supporting sub-assembly is attached to the cabinet, allowing the extending arm to slide and adjust for stability, with a blocking member that secures the arm and an adjustable foot to prevent the cabinet from tipping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If screws or stabilizing members are mounted to the bottom of the cabinet to prevent falling, then the cabinet stability is improved, but the device becomes too large and heavy for convenient use on anti-static floors

Engineering Contradiction:
Improvecabinet stabilityVSAvoidstabilizing member weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of stationary object

Solution Approach 1:

The patent applies the dynamics principle by replacing static, heavy stabilizing members with a dynamic telescopic leg assembly that can extend and retract. The telescopic mechanism allows the leg to provide full extension for stability when needed, while retracting to a compact size for convenient movement and storage, eliminating the need for permanently mounted heavy stabilizing members

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The stabilizing function is segmented into multiple telescopic leg assemblies rather than using a single large stabilizing member. Each leg assembly is divided into multiple telescopic sections that can independently extend and retract, allowing the stability function to be distributed across several lightweight, modular components

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If telescopic legs are used to stabilize the cabinet, then the cabinet becomes more mobile and suitable for anti-static floors, but the device complexity increases

Engineering Contradiction:
Improvecabinet mobilityVSAvoidtelescopic mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The telescopic leg assembly employs a nested doll principle where multiple leg sections are telescopically nested within each other. The inner sections slide within outer sections, allowing the leg to extend to full length for stability and retract to a compact size for mobility, achieving both ease of operation and controlled complexity through efficient space utilization

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

An anti-falling apparatus for a cabinet includes a receiving member (20) capable of being mounted to the cabinet. An extending arm (30) is slidably received in the receiving member. The extending arm includes a first end a second end, and is capable of moving from a first position to a second position. A supporting sub-assembly (50) is attached to the first end of the extending arm. A first distance from the first end to a top of the receiving member is greater than that a second distance from the second end to the top of the receiving member.
