Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi fan assemblies experience increased vibration leading to misalignment, noise, and inefficient assembly and maintenance due to numerous parts, which complicates fan mounting and electrical connections.
Innovation Solution
A multi fan assembly design featuring a simplified mount rack with interlocking members and positioning pins that securely lock fan modules, reducing vibration and streamlining assembly through reduced parts and precise electrical coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple fans are assembled together in a multi fan assembly, then cooling performance is improved, but vibration increases causing misalignment and noise
Solution Approach 1:
The patent combines multiple individual fan assemblies into a single integrated multi-fan assembly unit with a common housing and shared mounting structure. This merging approach allows the fans to operate together as one cohesive unit, improving overall cooling performance while the integrated structure helps dampen and reduce vibration compared to separate assemblies.
2Power
If multiple fans are assembled together, then cooling capacity increases, but misalignment occurs leading to increased noise
Solution Approach 1:
The patent integrates multiple fans into a single assembled unit with common mounting features and alignment mechanisms. This merging ensures that all fans maintain proper alignment during operation, preventing the misalignment that would otherwise occur with separate assemblies and thereby reducing noise generation.
3Reliability
If many parts are used in multi fan assemblies, then fan mounting and electrical connections are achieved, but assembly time increases
Solution Approach 1:
The patent employs pre-assembled fan modules where fans, housings, and electrical connections are prepared in advance as integrated units. These pre-configured modules can be quickly installed into the final assembly, eliminating the need to individually assemble multiple separate components and significantly reducing overall assembly time while maintaining connection reliability.
4Reliability
If many parts are used in multi fan assemblies, then complete fan mounting is achieved, but maintenance and repair become inconvenient
Solution Approach 1:
The patent divides the multi-fan system into modular fan assemblies, where each fan unit is contained within its own housing module. This segmentation allows individual fan modules to be easily removed, maintained, or replaced without affecting the other fans in the assembly, significantly improving maintenance convenience while ensuring complete mounting through standardized interfaces.
5Power
If vibration increases in multi fan assemblies, then more fans provide better cooling, but fasteners loosen
Solution Approach 1:
The patent combines multiple fans into a single integrated assembly with unified mounting brackets and fastening mechanisms. This merged structure distributes vibration forces across the entire assembly rather than concentrating them on individual fasteners, and the increased mass of the combined unit helps dampen vibration, preventing fastener loosening while maintaining improved cooling performance.

AI summary
A multi fan assembly may include a multi fan mount rack and a plurality of fan modules. The multi fan mount rack includes a housing and a mount bracket fixedly disposed to the housing. The mount bracket and housing define a mount space therewithin. Each plurality of fan modules includes a fan frame and a fan assembly rotatably disposed within the fan frame. The fan frame comprises at least two interlocking members, each, respectively disposed protruding from a top plane of the fan frame. The at least two interlocking members is configured to lock each plurality of fan modules to the multi fan mount rack within the mount space, wherein each plurality of fan modules is locked to the multi fan mount rack via a pushing force.
