Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fan modules for servers are costly and cumbersome to assemble due to multiple parts, leading to misalignment issues and an unstable structure, which can result in the fan module loosening and falling off.
Innovation Solution
A server design featuring a chassis with a holder and a fixing member that includes a hook set with a first and second hook, allowing for secure attachment to the holder, reducing the need for additional fixing parts and simplifying assembly, while maintaining structural stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple parts are used to assemble the fan module, then the fixing strength can be improved, but the assembly complexity and production cost increase
Solution Approach 1:
The patent combines multiple fixing parts into a single integrated fixing member with a unified structure. The fixing member includes a holding portion and a fixing portion that work together as one component, eliminating the need for separate screws, clips, or other fastening elements. This merging approach maintains strong fixing capability while significantly simplifying the assembly process and reducing part count.
Solution Approach 2:
The fixing member is designed to perform multiple functions within a single component: it holds the electronic device, provides fixing attachment, and enables easy installation and removal. The integrated structure serves as both the mounting bracket and the fastening mechanism, eliminating the need for separate fixing parts and reducing overall assembly complexity.
2Reliability
If multiple parts are used to assemble the fan module, then the fixing reliability can be improved, but the alignment precision deteriorates
Solution Approach 1:
By integrating the holding portion and fixing portion into a single fixing member, the patent eliminates alignment issues between multiple separate parts. The unified structure ensures that the electronic device is held and fixed in the correct position without requiring precise alignment between multiple components during assembly.
Solution Approach 2:
The fixing member is pre-configured with the holding portion and fixing portion in the correct spatial relationship. This preliminary arrangement ensures that when the fixing member is installed, the electronic device is automatically positioned correctly without requiring additional alignment steps or adjustments during assembly.
3Stability of the object's composition
If multiple parts are used to assemble the fan module, then the structural stability can be improved, but the production cost increases
Solution Approach 1:
The patent consolidates multiple fixing parts into a single integrated fixing member that can be manufactured as one piece. This reduces the number of manufacturing steps, eliminates the need for assembling multiple small parts, and lowers production costs while maintaining structural stability through the unified design.
Solution Approach 2:
The fixing member is designed with optimized geometric parameters and material properties that provide structural stability equivalent to or better than multiple separate parts. The integrated structure allows for better stress distribution and structural integrity while reducing manufacturing complexity and cost.

AI summary
A server includes a chassis and an electronic device assembly. The electronic device assembly includes a holder and a fixing member. The holder accommodates an electronic device and includes a limiting slot and a positioning hole. The fixing member includes a hook set. The hook set includes a first hook and a second hook. The first hook is connected to the limiting slot to be limited in a first direction. The second hook is connected to the positioning hole to be limited in a second direction. The first direction is substantially different from the second direction. The fixing member and the holder sandwich a connector connected to the electronic device.
