Height-Adjustable Fan Fixing Structure for Server Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fan fixing structures in server and memory products are not adaptable to different height scenarios, limiting the use of the same type of fan across various configurations due to varying layout requirements, which can lead to inadequate heat dissipation and system shutdown risks.
Innovation Solution
A height adjustable fan fixing structure that includes a fan box rear cover, fan box front cover, and a height adjusting block with rotatable wire plugs and damping pads, allowing for tool-free and precise adjustment of the fan's height using a method that involves loosening wire plugs, adjusting the height block, and aligning the connector fixing seat, enabling the same fan type to be used across different heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different fixing structure forms are used for different height scenarios, then the fan can be securely fixed at various heights, but the same type of fan cannot be used universally across different configurations
Solution Approach 1:
The patent implements a universal fixing structure where a single fan model can be installed at multiple height positions (e.g., 1st, 2nd, 3rd, 4th positions) using the same fixing mechanism. The fixing structure includes adjustable components that allow the fan to be securely mounted at different vertical positions within the chassis without requiring different fan types or completely different fixing mechanisms, thus achieving multi-functionality and universality.
Solution Approach 2:
The fixing structure incorporates dynamic adjustment capabilities through movable fixing blocks and adjustable mounting positions. The structure allows for height adjustment during installation and maintenance, enabling the same fixing mechanism to adapt to different height requirements. This dynamic characteristic resolves the contradiction by making the fixing structure flexible rather than fixed, allowing universal application across different scenarios.
2Stability of the object's composition
If fixed fixing structures are used for each height position, then the fan is securely mounted, but the structure cannot be adjusted for different height requirements
Solution Approach 1:
The fixing structure transforms from a static, fixed-position design to a dynamic, adjustable design. The structure includes movable components such as adjustable fixing blocks and repositionable mounting elements that allow the fan to be securely mounted at different height positions. This dynamic characteristic enables both secure mounting (stability) and height adjustment (adaptability) simultaneously.
Solution Approach 2:
The fixing structure is divided into modular segments that can be independently adjusted. The fixing mechanism includes separate adjustable components (e.g., individual fixing blocks at different positions, modular mounting elements) that can be configured for different height requirements while maintaining secure mounting. This segmentation allows flexibility in positioning while preserving the stability of each individual mounting point.
3Adaptability or versatility
If multiple types of fans are used for different height scenarios, then each height position has an optimized fan, but the inventory and maintenance costs increase
Solution Approach 1:
The patent achieves universality in the fixing structure, allowing a single fan type to be installed at multiple height positions (1st, 2nd, 3rd, 4th positions) within the chassis. This eliminates the need to maintain multiple fan types for different heights, reducing spare parts inventory to just one fan model while still providing optimized cooling for different scenarios through the adjustable fixing mechanism rather than through different fan types.
