Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rack-mounted computers face challenges in space-saving and easy maintenance of fans due to high-density arrangements, where existing mounting solutions do not efficiently utilize available space and complicate fan installation and removal processes.
Innovation Solution
A mounting apparatus for fans featuring a rotatable locking unit with a resilient member, allowing the fan to be easily locked and unlocked within a housing, enabling secure installation and removal from a casing while minimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing mounting solutions are used in rack-mounted computers, then fan installation is possible, but space efficiency is reduced and maintenance becomes complicated
Solution Approach 1:
The mounting apparatus integrates multiple functional components within a compact structure. The fan is nested within a housing that includes integrated mounting features, allowing the entire assembly to occupy minimal space while maintaining ease of installation and removal through the rotatable locking mechanism.
Solution Approach 2:
The rotatable locking unit provides dynamic mounting and demounting capability. By rotating the locking unit between locked and unlocked positions, the fan can be quickly installed or removed without complex tools or procedures, significantly improving ease of operation while maintaining compact dimensions.
2Ease of repair
If existing mounting solutions are used, then fan fixation is achieved, but maintenance accessibility is reduced
Solution Approach 1:
The mounting apparatus is segmented into distinct functional components: the housing, the rotatable locking unit, and the fan assembly. This segmentation allows the fan to be independently accessed and maintained by simply unlocking and removing it from the housing, greatly simplifying maintenance procedures without requiring disassembly of the entire mounting structure.
Solution Approach 2:
The rotatable locking unit is pre-configured to provide quick lock and unlock functionality. The resilient member is pre-positioned to engage with the locking unit, enabling rapid maintenance operations without requiring complex adjustment or preparation steps.
3Area of stationary object
If compact mounting is implemented, then space efficiency improves, but locking reliability may be compromised
Solution Approach 1:
The rotatable locking unit utilizes a resilient member with curved or arc-shaped geometry that provides reliable engagement through rotational movement. The curved path of the resilient member ensures consistent and reliable locking force while maintaining a compact overall structure, preventing fan loosening or detachment during operation.

AI summary
A mounting apparatus for an easily-demountable fan and cooling devices includes a fan housing for accommodating the fan and a locking unit rotatably installed to the fan housing. The locking unit is rotatable between a locking position and an unlocking position. The locking unit includes a locking portion. When the locking unit rotates to the locking position, the locking portion protrudes out of the fan housing for easy manual access, and when the locking unit rotates to the unlocking position, the locking portion is received in the fan housing.
