Solution Overview

Problem

Existing cooling systems for information handling systems face challenges in efficiently accommodating cooling fans of varying sizes, leading to inefficiencies and increased costs due to the need for replacing fan brackets, which can result in gaps and recirculation of air, degrading cooling performance.

Innovation Solution

A reconfigurable cooling fan holder with adjustable dimensions and sealing mechanisms, such as foldable sealing plates and adjustable position resiliency screws, allows for easy installation and customization of cooling fans of different sizes without compromising cooling efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-size fan bracket is used, then the manufacturing cost is reduced and the structure is simplified, but the system cannot accommodate fans of varying sizes and the cooling performance degrades due to gaps and air recirculation

Engineering Contradiction:
Improvecompatibility with fans of varying sizesVSAvoidfan bracket structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fan bracket incorporates adjustable components including resiliency screws with threaded engagement and foldable sealing plates that can be reconfigured between multiple positions. This dynamic structure allows the same bracket to adapt to different fan sizes while maintaining secure mounting and proper sealing, resolving the contradiction between adaptability and structural simplicity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The fan bracket is designed as a universal mounting structure that can accommodate multiple fan sizes (e.g., 80mm, 92mm, 120mm, 140mm) using the same bracket body. The resiliency screws and foldable sealing plates provide multi-functional capability to adjust both mounting position and sealing configuration, eliminating the need for multiple dedicated brackets for different fan sizes

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

2Adaptability or versatility

If the fan bracket is made reconfigurable to accommodate different fan sizes, then the adaptability is improved, but the manufacturing cost and complexity increase

Engineering Contradiction:
Improvecustomization capability for different fan sizesVSAvoidfan bracket production
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The fan bracket is divided into distinct functional segments: the main bracket body, adjustable resiliency screws, and foldable sealing plates. Each segment can be manufactured independently using standard machining processes, and then assembled together. This segmentation allows for simplified manufacturing of individual components while achieving the complex adaptive function through their combination

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The resiliency screws feature nested threaded engagement where the screw thread integrates with the bracket body structure. The foldable sealing plates are nested within the bracket framework, folding flat when not in use. This nesting approach minimizes the overall component count and reduces manufacturing complexity while maintaining the reconfigurable adaptability

Inventive Principle:
Principle #7Nested doll (Nesting)

3Manufacturing precision

If standard mounting screws are used without adjustment capability, then the manufacturing is simpler, but the mounting precision and cooling performance are compromised due to improper fit

Engineering Contradiction:
Improvefan mounting precisionVSAvoidmounting mechanism
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The resiliency screws incorporate adjustable threaded engagement that allows precise positioning of the fan mounting points. By changing the engagement depth and position of the screws along the threaded path, the mounting precision can be optimized for different fan sizes and configurations, ensuring proper alignment and secure attachment without requiring complex custom-machined components

Inventive Principle:
Principle #35Parameter changes
