Pull-out aiding device and chassis-wall module with pull-out aiding function
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, which allows for easy and convenient removal of apparatus by pivoting and moving the handle member between closed and pulled-out positions, overcoming the limitations of conventional mechanisms.
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 movement distance is limited to 3-5mm making it difficult to remove due to partitioning walls
Solution Approach 1:
The unloading mechanism is transformed from a static push structure to a dynamic lever system with pivot sections. The first pivot section allows the pulling member to rotate, while the second pivot section enables the handle member to swing between closed and pulled-out positions, creating a dynamic mechanical advantage system that extends the effective pull distance beyond the limited 3-5mm push distance.
Solution Approach 2:
The mechanism introduces rotational motion around pivot sections as a new dimension of movement. Instead of purely linear push motion, the handle member swings in an arc around the second pivot section, and the pulling member rotates around the first pivot section, converting limited linear displacement into extended operational reach that overcomes the partitioning wall constraint.
2Ease of operation
If the unloading mechanism moves the apparatus by a small distance, then the structure remains compact, but the user cannot easily remove the ejected card from the chassis
Solution Approach 1:
The lever system with two pivot sections creates a dynamic amplification effect. When the handle member swings from the closed position to the pulled-out position, it rotates around the second pivot section, causing the abutting section to pull the apparatus forward by a distance much greater than the handle's own displacement, effectively extending the ejection distance without increasing chassis depth.
Solution Approach 2:
The pulling member acts as an intermediary between the handle member and the apparatus. It transfers and amplifies the motion from the handle's swinging motion around the second pivot section into a larger linear pull on the apparatus through rotation around the first pivot section, enabling the user to pull out the apparatus far enough to clear the partitioning walls.
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 effortless and convenient removal of apparatus from the chassis by allowing greater movement and engagement with the partitioning walls, facilitating easy access and handling of components.
Implementation Method 1
The pulling member is movably coupled with the first partitioning wall and includes a first pivot section and an abutting section. 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.

AI summary
A pull-out aiding device is configured for mounting on an object, in which a corresponding apparatus is mounted. The pull-out aiding device includes a pulling member and a handle member. The pulling member includes a first pivot section and an abutting section for abutting against the corresponding apparatus to move the latter forward. 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 relative to the pulling member and brings the latter to move forward.
