Server Chassis Linkage Tray Assembly Without Rails or Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of server chassis manufacturing due to expensive rails and complex, space-occupying handles, which hinder automated assembly of trays and circuit boards.
Innovation Solution
A chassis design featuring a pivotally connected operating member with linkage portions that allows the tray to be easily assembled and disassembled using a simple mechanism, eliminating the need for inner and outer rails and reducing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If inner and outer rails are disposed on the chassis and tray for sliding installation, then the tray can be installed in the chassis, but the manufacturing cost increases due to high price of rails
Solution Approach 1:
The patent removes the inner and outer rails from the system entirely. Instead of using rails for installation, the tray is directly installed on the chassis through a simplified structure that eliminates the need for separate rail components, thereby reducing manufacturing cost and structural complexity
Solution Approach 2:
The chassis structure is designed to perform multiple functions without requiring separate rail components. The chassis itself provides both the mounting function and the structural support, making the system more cost-effective while maintaining functionality
2Ease of operation
If a handle is equipped on the tray for extraction, then the tray can be extracted manually, but the mechanism becomes complicated and occupies space
Solution Approach 1:
The patent removes the handle mechanism from the tray structure. Instead of using a separate handle component for extraction, the tray is designed to be directly accessible and removable through the simplified installation structure, eliminating the need for complex handle mechanisms
Solution Approach 2:
The extraction function is separated from the tray structure itself. The tray can be easily removed through the simplified mounting mechanism without requiring an integrated handle, allowing for cleaner design and reduced complexity while maintaining ease of operation
3Ease of operation
If a handle mechanism is added to the tray, then manual extraction is enabled, but automated assembly becomes difficult due to space occupation
Solution Approach 1:
The handle mechanism is completely removed from the system. The simplified tray structure without handles allows automated assembly equipment to access and manipulate the tray directly, enabling automation while maintaining ease of manual operation through the simplified mounting mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates automated assembly of trays and circuit boards, reduces manufacturing costs, and optimizes space utilization.
Implementation Method 1
The operating member is pivotally connected to the fixing base
Implementation Method 2
The operating member comprises a first linkage portion. The tray is disposed on the fixing base. The tray comprises a second linkage portion corresponding to the first linkage portion
Implementation Method 3
When the operating member is located at a closed position, the operating member and the fixing base are locked
Implementation Method 4
When the operating member rotates from the closed position to an opened position, the first linkage portion pushes the second linkage portion to drive the tray to move toward outside of the fixing base

AI summary
A chassis includes a fixing base, an operating member, a tray and a cover. The operating member is pivotally connected to the fixing base. The operating member includes a first linkage portion. The tray is disposed on the fixing base. The tray includes a second linkage portion corresponding to the first linkage portion. The cover is disposed on the fixing base and covers the tray. When the operating member is located at a closed position, the operating member and the fixing base are locked, and the first linkage portion blocks the second linkage portion, so as to fix the tray on the fixing base. When the operating member rotates from the closed position to an opened position, the first linkage portion pushes the second linkage portion to drive the tray to move toward outside of the fixing base.
