Pivoting Pull-Out Aiding Device to Overcome Chassis Partitioning Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chassis unloading mechanisms can only move hard disks or circuit boards by a small distance, making it difficult to easily remove them due to partitioning walls and other apparatus within the chassis.
Innovation Solution
A pull-out aiding device with a pulling member and handle member, including pivot sections, abutting sections, and a releasable fastening element, that allows for easy and convenient removal of apparatus by pivoting and moving the pulling member relative to the partitioning walls, with limiting units to control the movement and prevent over-pulling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional unloading mechanism is used, then the hard disk or circuit board can be separated from the connection port, but the ejection distance is limited to 3-5 mm making it difficult to remove due to partitioning walls
Solution Approach 1:
The pull-out aiding device employs a dynamic linkage mechanism with pivot sections that allow the pulling member to move through a larger arc, transforming the limited linear motion of conventional mechanisms into extended curved motion that achieves greater ejection distance while maintaining mechanical advantage
Solution Approach 2:
The invention introduces a multi-dimensional motion path using the pivot section configuration, where the pulling member moves not only linearly but also angularly around the pivot point, effectively adding a rotational dimension to the ejection motion to overcome the partitioning wall constraint
2Ease of operation
If the unloading mechanism moves the hard disk by a small distance, then the connection port separation is achieved, but the partitioning walls hinder easy removal of the ejected card
Solution Approach 1:
The pull-out aiding device acts as an intermediary mechanical system between the user's manual operation and the hard disk removal process, providing the additional force and distance multiplication needed to clear the partitioning wall obstacle that cannot be overcome by direct manual pulling alone
3Length of moving object
If a pull-out aiding device with pivot sections is used, then the ejection distance is increased, but the device complexity increases with additional components
Solution Approach 1:
The invention merges the pulling member, pivot section, and abutting section into an integrated assembly that works as a unified mechanism, where the pivot section serves dual purposes as both a motion articulation point and a structural support element, reducing the need for separate components
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
Enables the easy and effortless removal of apparatus from the chassis by allowing the handle member to pivot and move the pulling member, overcoming the limitations of conventional unloading mechanisms, allowing for greater distance and ease of removal.
Implementation Method 1
The handle member includes a second pivot section and an operating section. The second pivot section is pivotally connected to the first pivot section, such that the handle member is turnable about the second pivot section.
Implementation Method 2
The abutting section of the pulling member is moved forward relative to the first partitioning wall by a pulling distance when the handle member is in the pulled-out position.
