Solution Overview

Problem

Information handling systems, such as servers, experience undesirable rotational vibration from components like storage drives, leading to inoperability and acoustic noise, which existing technologies fail to adequately mitigate.

Innovation Solution

A component carrier system with guide flanges oriented to balance the mass on both sides of the carrier, minimizing rotational vibration by defining a plane that equalizes the combined mass on each side when a component is mounted, thereby reducing vibrational interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If components with motors or mechanical devices are installed in the chassis, then the system can perform required functions, but rotational vibration occurs causing inoperability and acoustic noise

Engineering Contradiction:

Improvefunctional capabilityVSAvoidrotational vibration

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies the counterweight principle by positioning guide flanges to create a balanced mass distribution on the component carrier. The flanges are oriented such that the combined mass on a first side of the carrier plane equals the combined mass on a second side, creating a counterbalancing effect that reduces rotational vibration generated by motor-driven components like storage drives.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

2Device complexity

If components are mounted directly in the chassis, then the system structure is simple, but vibration causes inoperability and interference with other components

Engineering Contradiction:

Improvestructural simplicityVSAvoidoperational stability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent introduces a component carrier with guide flanges as an intermediary element between the chassis and the component. This carrier serves as a mediating structure that isolates the component from direct mounting to the chassis, allowing the component to be secured while the guide flanges provide vibration reduction through balanced mass distribution, thereby improving operational stability without significantly increasing overall structural complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If traditional mounting methods are used, then manufacturing is simple, but acoustic noise and vibrational interference occur

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidacoustic noise

Core Design Contradiction:

Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent employs asymmetric positioning of guide flanges relative to the component carrier structure. The flanges extend from specific sides of the carrier at defined orientations, creating an asymmetric mass distribution pattern that is deliberately designed to balance forces during rotational operation. This asymmetric design achieves vibration reduction while maintaining manufacturing simplicity through standard fabrication processes.

Inventive Principle:

Principle #4Asymmetry
