Pivoting Handle Tool for Deep PCB Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer system architecture, it is challenging to easily insert and remove modules, such as printed circuit boards (PCBs), from deep within slim enclosures while maintaining structural integrity and accessibility, especially when they need to be Field Replaceable Units (FRUs).
Innovation Solution
A device with a single, elongated structure featuring a module mounting region and a pivotally mounted handle allows for the insertion and removal of PCBs from deep within slim enclosures, minimizing volume impact and enabling easy access by folding the handle for grabbing and extracting the module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an access panel is provided on the top, bottom, or sides of the enclosure to enable module removal, then the module can be extracted, but the structural integrity is reduced and EMI shielding is compromised
Solution Approach 1:
The device is segmented into distinct functional regions: a module mounting region for securing the PCB, an intermediate region for structural connection, and a handle portion for user operation. This segmentation allows each region to be optimized independently while maintaining overall structural integrity of the enclosure.
Solution Approach 2:
The device acts as an intermediary tool that enables module extraction without creating permanent openings in the enclosure. By providing a removable access mechanism with a handle that pivots to engage and disengage the module, it achieves ease of operation while preserving the enclosure's structural integrity and EMI shielding.
2Ease of operation
If an access panel is provided on the enclosure to enable module removal, then the module can be extracted, but the device becomes expensive and requires EMI shielding
Solution Approach 1:
The device merges multiple functions into a single integrated structure: the module mounting region, the intermediate structural region, and the handle portion are combined into one piece that performs both structural support and user operation functions, reducing the need for separate EMI shielding components and access panels.
Solution Approach 2:
The device serves multiple purposes: it provides structural support for the module, acts as a mounting mechanism, and functions as a removal tool through its pivoting handle. This multi-functionality eliminates the need for separate access panels and EMI shielding structures, reducing manufacturing costs.
3Shape
If the module is buried deep inside the slim enclosure to optimize architecture, then the enclosure design is optimized, but the module becomes difficult to access and remove
Solution Approach 1:
The handle portion pivots about an axis perpendicular to the longitudinal axis of the device, creating a dimensional change in the access mechanism. This perpendicular pivoting motion allows the handle to reach the module at the deep interior location while the user interacts with the device from the exterior, solving the accessibility problem without compromising the slim enclosure architecture.
4Ease of operation
If a handle is made movable to enable module extraction, then the module can be removed easily, but the device complexity increases
Solution Approach 1:
The handle portion is designed to be movable rather than fixed, pivoting about an axis perpendicular to the longitudinal axis. This dynamic element allows the handle to transition between engaged and disengaged positions, enabling easy module extraction while maintaining relatively simple device architecture through a single pivot mechanism.
