Rotary Fan Module Mounting for Faster Server Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficient and labor-intensive process of mounting and dismounting fans in servers due to traditional fixing methods, such as bolts or latches, hinders maintenance efficiency.
Innovation Solution
A fan module mounting device with a positioning and connection base and a rotary mounting cylinder, utilizing a blocking and locking snap mechanism, allows for quick and convenient fan installation and removal by pivoting the rotary mounting cylinder between working and maintenance states, facilitated by a lifting elastic member and snap-fit flange system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixing methods (bolts or latches) are used to mount fans, then the fan mounting is stable and reliable, but the mounting and dismounting process becomes labor-intensive and time-consuming
Solution Approach 1:
The fan mounting device is divided into separate functional components: a positioning base that remains fixed in the server, and a rotary mounting cylinder that can be independently rotated and locked. This segmentation allows the stable positioning function to be maintained while enabling quick rotation-based mounting and dismounting operations without requiring multiple fasteners.
Solution Approach 2:
The mounting cylinder is designed to rotate between different angular positions, transitioning from a locked position (where the blocking snap engages to secure the fan) to an unlocked position (where the fan can be removed). This dynamic rotation mechanism replaces static bolted connections with a movable locking system that maintains reliability during operation while enabling rapid maintenance.
2Stability of the object's composition
If multiple bolts or latches are used to secure the fan, then the fan remains firmly fixed during operation, but the number of fastening components increases and complicates the mounting structure
Solution Approach 1:
Multiple fastening functions are merged into a single integrated rotary mounting cylinder with one blocking and locking snap mechanism. Instead of requiring multiple separate bolts or latches distributed around the fan, the design consolidates the securing function into one rotational locking action, reducing the number of components while maintaining firm fixation during operation.
Solution Approach 2:
The rotary mounting cylinder serves multiple functions: it positions the fan during insertion, secures the fan in the locked position through the blocking snap, and enables removal when rotated to the unlocked position. This multi-functional design replaces what would traditionally require separate positioning features, fastening mechanisms, and release systems, thereby simplifying the overall mounting structure.
3Reliability
If frequent fan maintenance is required, then heat dissipation can be optimized, but the repeated mounting and dismounting increases operational workload
Solution Approach 1:
The rotary mounting cylinder is pre-configured with the blocking and locking snap mechanism positioned to automatically engage when the fan is inserted and rotated into place. This preliminary setup of the locking mechanism eliminates the need for manual fastening operations during each maintenance cycle, allowing technicians to quickly install or remove fans by simply rotating the cylinder without performing additional fastening actions.

Implementation Method 1
a lifting elastic member arranged between the rotary mounting cylinder and the positioning and connection base
Implementation Method 2

AI summary
A fan module mounting device includes a positioning and connection base fixed inside a case; a bottom surface of a connecting end of a rotary mounting cylinder is hinged to the positioning and connection base; and a pick-and-place end of the rotary mounting cylinder is provided with a passage for a fan to enter and exit. The positioning and connection base is provided with a blocking and locking snap; in the working state, the blocking and locking snap blocks and limits the fan, thereby limiting the fan and ensuring that the fan cannot move out from the rotary mounting cylinder. During dismounting, it is only necessary to release the limiting of the blocking and locking snap on the rotary mounting cylinder, the rotary mounting cylinder is rotated and lifted upward, the fan is picked from the rotary mounting cylinder.
