Ejectable Fan with Push-Push Latching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fan systems in server systems require frequent replacement due to mechanical wear, necessitating disassembly and specialized tools, which is time-consuming and costly, and often requires shutting down the system for maintenance.
Innovation Solution
A fan module and receiver assembly with a push-push latching mechanism that allows for easy replacement of fans without tools or specialized skills, using deformable clasps and coiled springs to secure the fan module in place, enabling 'hot swapping' and simplifying the replacement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fan mounting methods are used, then the fan is securely fixed in the chassis, but the fan replacement requires disassembly, specialized tools, and system shutdown
Solution Approach 1:
The fan assembly is divided into a fan module and a receiver assembly, allowing the fan to be independently replaced without affecting the entire cooling system or requiring chassis disassembly
Solution Approach 2:
The deformable clasp mechanism provides dynamic retention, where the clasp automatically deforms to release the fan during ejection and locks into place during installation, enabling tool-free hot-swappable replacement
2Reliability
If fans are replaced frequently due to mechanical wear, then reliable cooling is maintained, but maintenance time and costs increase
Solution Approach 1:
The receiver assembly is pre-installed in the chassis with retention mechanisms ready, allowing the fan module to be quickly swapped without requiring preparation or system shutdown, reducing maintenance downtime
Solution Approach 2:
The deformable clasp mechanism enables users to perform fan replacement themselves without specialized tools or technical expertise, eliminating the need for trained technicians and reducing maintenance costs
3Manufacturing precision
If specialized technicians are required for fan replacement, then proper installation is ensured, but replacement cost increases
Solution Approach 1:
The push-push ejection mechanism and deformable clasp are designed to be operated by any user without specialized training, eliminating the need for certified technicians and reducing service costs
Solution Approach 2:
The mechanical deformable clasp mechanism replaces complex tool-based fastening systems, simplifying the replacement process to manual insertion and ejection actions that require no specialized knowledge

AI summary
A fan receiver assembly (1200) includes a fan receiver (101). The fan receiver includes a rear wall (128) and at least one sidewall (112). At least one deformable clasp (105) is coupled to, and translatable along, the sidewall. The deformable clasp includes at least one latching arm (142) that is pivotable between an axially displaced open position occurring when the latching arm extends beyond a terminal end sidewall and a parallel position occurring when the latching arm is situated between the terminal end and the rear wall. The sidewall defines a d-track (111) having a terminal end (125) and an outward notch (126). A follower situates within the d-track between the deformable clasp and the sidewall. A fan module (102) latches to the fan receiver assembly when the follower situates within the outward notch.
