Tool-less PCB Extraction Device with Integrated Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handle devices for extracting printed circuit boards often damage the boards and components due to direct contact and require complex installation processes, including flipping the board to attach screws from the bottom, which can be risky and inconvenient.
Innovation Solution
A board extraction device with integrated mounting featuring a base portion, rivets, a flexible handle, and pins that securely attach to the circuit board without the need for tools, minimizing contact with components and allowing for easy handling and installation by inserting rivets and pins through openings, and connecting a flexible handle for secure extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws and washers are used to fix the handle device to the PCB, then the mounting is secure, but the installation process becomes complex and requires tools
Solution Approach 1:
The patent combines the mounting function into the base portion itself, which is directly disposed on the opening of the circuit board. The base portion integrates the mounting structure without requiring separate screws and washers, thereby simplifying the installation process while maintaining secure mounting through the integrated design
Solution Approach 2:
The patent extracts the screws and washers from the mounting system, eliminating the need for these separate components. The mounting function is achieved through the base portion and rivet structure alone, removing the complexity associated with tool-based screw installation
2Reliability
If the handle device is installed using screws from the bottom of the PCB, then secure mounting is achieved, but the risk of damaging components increases
Solution Approach 1:
The patent inverts the installation approach by mounting the handle device from the top surface of the circuit board through the opening, rather than from the bottom surface. This inversion eliminates the need to flip the board and attach screws from underneath, thereby reducing the risk of damaging components during installation while achieving secure mounting
3Adaptability or versatility
If multiple separate components are used for the handle device, then the functionality is complete, but the device footprint increases
Solution Approach 1:
The patent merges multiple separate components (handle, base portion, mounting structure) into an integrated assembly where the base portion is directly disposed on the circuit board opening. This integration reduces the overall device footprint while maintaining complete functionality through the unified structure
Solution Approach 2:
The patent employs a nested structure where the base portion is disposed within the opening of the circuit board, and the handle is connected to the base portion. This nesting arrangement minimizes the external footprint of the device while preserving all necessary functional components

AI summary
A board extraction device with integrated mounting includes a base portion configured to be disposed on an opening of a circuit board, a rivet extending from a surface of the base portion and configured to pass through the opening, a handle flexibly connected to the base portion, and a pin flexibly connected to the base portion. The rivet has a hole extending therethrough. The pin engages the hole so as to fix the base portion to the circuit board.
