Fan Unit With Pivoting Handle For Quick Connector Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fan modules in electronic devices, such as servers, are difficult to assemble, remove, and maintain quickly due to their design, which hinders efficient heat dissipation and increases manufacturing costs.
Innovation Solution
A fan unit with a fixture, fan, and handle that allows for easy assembly and removal by pivotally moving the handle to connect and disconnect the fan unit mechanically and electrically, using a flexible bolt and guiding structure for secure fixation and alignment, and accommodating wires for smooth installation of the fan indicator light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fan unit uses upper and lower elastic members disposed in side of fan unit for latching, then the fan unit can be secured in the fan bracket, but the assembly and removal process becomes time-consuming and complex
Solution Approach 1:
The fan unit is divided into separable components including the fan bracket, elastic members, and fan assembly. The elastic members are positioned at specific locations (upper and lower sides) to provide independent latching functions, allowing the fan unit to be secured through distributed attachment points rather than a single complex mechanism.
Solution Approach 2:
The elastic members are designed to automatically engage and latch the fan unit in the fan bracket without requiring additional fastening operations. The elastic deformation of these members provides self-latching functionality, where the members naturally snap into position to secure the fan unit, eliminating the need for manual tightening or complex assembly procedures.
2Stability of the object's composition
If the fan unit uses elastic members for latching, then the fan unit can maintain stable connection, but the removal and maintenance process becomes difficult and slow
Solution Approach 1:
The elastic members are designed with dynamic characteristics that allow them to deform and flex during the attachment and removal processes. When the fan unit is installed, the elastic members deform to engage the latching features, providing stable connection. During removal, the elastic members can deform in reverse to release the latch, enabling easy detachment without permanent deformation or damage.
Solution Approach 2:
The elastic members utilize changes in their physical state (elastic deformation) to achieve both secure connection and easy removal. By controlling the degree and direction of elastic deformation, the system transitions between a locked state (when deformed to engage) and a released state (when returned to original position), providing both stability and operational ease.

AI summary
The invention relates to a method for assembling a fan unit into an electronic device and removing therefrom. The electronic device has a first connector. The fan unit includes a fixture, a fan, a second connector and a handle. The fan is assembled into the fixture and electrically connected to the second connector. The handle is pivotally connected to the fixture and operable to be pivotally moved between a first position and a second position of the fixture. When the handle is operated to move to the first position, the fixture is pushed to approach to the first connector, so as to so as make the second connector connect to the first connector in mechanical and electrical. When the handle is operated to move to the second position, the fixture is pulled out by the handle, so as to make the second connector disconnected to the first connector.
