Server Tray Handle with Elastic Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the assembly and disassembly of server chassis in communication and information centers, the rapid counter-acting force generated can lead to the ejection of assistant handles, causing operator injury and instability due to the swinging of handles.
Innovation Solution
A tray and electronic device design that incorporates a handle with an elastic component featuring a first protrusion portion, which is selectively locked in either the first or second locking hole of the mounting plate, decelerating the handle's ejection speed and enhancing operator convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the chassis is disengaged from the cabinet, then the connector connection is released, but the assistant handle is instantly ejected out from the cabinet by the counter-acting force, causing operator injury
Solution Approach 1:
The elastic component is pre-installed on the handle to provide cushioning during the disassembly process. When the chassis is disengaged from the cabinet, the elastic component compresses to absorb the counter-acting force, preventing the handle from being instantly ejected and causing operator injury.
Solution Approach 2:
The elastic component acts as an intermediary between the handle and the counter-acting force generated during disassembly. It mediates the force transmission, converting the sudden ejection force into controlled compression and rebound, thereby preventing direct impact on the operator.
2Adaptability or versatility
If there is a gap between the assistant handle and the chassis for accommodating components, then components can be installed, but the assistant handle is easy to swing in the operating process, requiring more power to stabilize the movement
Solution Approach 1:
The elastic component introduces dynamic characteristics to the handle system. Instead of a fixed rigid connection, the elastic component allows controlled movement and rebound, enabling the handle to adapt to operational forces while maintaining stability through elastic restoration rather than rigid constraint.
Solution Approach 2:
The elastic component changes the mechanical parameters of the handle system by introducing elasticity. This transforms the handle from a rigid structure prone to swinging into a system with controlled compliance, where the elastic force provides stabilizing feedback during operation.
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
The elastic component effectively reduces the risk of operator injury by decelerating the handle's ejection speed, while also providing convenience during operation by stabilizing the handle's movement.
Implementation Method 1
an elastic component disposed on the handle and includes a first protrusion portion... The elastic component may decelerate the ejection speed of the handle

AI summary
A tray is for an electronic device. The tray includes a bottom plate, a mounting plate, a handle, and an elastic component. The mounting plate is fixed on the bottom plate, and includes a first locking hole and a second locking hole. The handle is disposed pivotally on the bottom plate. The handle is disposed between the mounting plate and the bottom plate. The handle includes a through groove and a holding portion. The holding portion is disposed at one end of the handle and is exposed out of the bottom plate. In addition, the elastic component is fixed on the handle and includes a first protrusion portion. The first protrusion portion in the through groove protrudes toward the mounting plate, and is selectively disposed in the first locking hole or the second locking hole.
