Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of printed circuit board assemblies is challenging due to the need for precise alignment of connectors, which can be damaged by uneven or excessive force, and poses risks of injury from direct handling of electronic components.
Innovation Solution
A circuit board mounting and demounting device using a guide and fulcrum mechanism with an actuation mechanism, including a substrate and linkage assembly, allows for force-saving alignment and assembly without direct contact, using a handle to pivot an actuating rod for precise connector alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user directly handles and applies force to assemble printed circuit board assemblies, then the assembly process can be performed manually, but the connectors may be damaged due to uneven or excessive force, and the user may be injured from direct contact with electronic components
Solution Approach 1:
The patent introduces a mechanical assembly device as an intermediary between the user and the circuit boards. This device includes a holding mechanism that securely grasps the first circuit board and a pushing mechanism that applies controlled force to push the second circuit board into alignment and connection. The mechanical device mediates the interaction, ensuring even force distribution through guide rails and alignment features, thereby preventing connector damage while maintaining ease of operation.
2Area of stationary object
If the size of printed circuit board assemblies is large, then more electronic components can be accommodated, but a considerable force is required for holding and inserting during assembly
Solution Approach 1:
The mechanical assembly device serves as an intermediary that amplifies and directs the user's input force. The pushing mechanism with lever arms and the guide rail system provide mechanical advantage, allowing the user to apply a smaller force that is then magnified and distributed evenly across the large circuit board assembly. This resolves the contradiction by enabling handling of large assemblies without requiring proportionally large forces.
Solution Approach 2:
The assembly device segments the assembly process into distinct phases: the holding mechanism secures the first board, the pushing mechanism applies force to the second board, and the guide rails provide alignment. This segmentation allows each component to be optimized for its specific function, reducing the overall force required compared to manual handling of the entire large assembly.
3Manufacturing precision
If connectors need to be accurately aligned between two circuit board assemblies, then electrical connection quality improves, but the alignment process becomes more difficult and time-consuming
Solution Approach 1:
The guide rails and alignment features are pre-configured on the mechanical assembly device and circuit boards. Before the actual connection process, the device establishes the correct alignment geometry through its rigid guide structure. This preliminary setup ensures that when the pushing mechanism operates, the connectors are already positioned for accurate engagement, eliminating the need for complex real-time adjustment mechanisms during assembly.

AI summary
A circuit board mounting and demounting device, which is used with a guide and fulcrum device, includes at least one actuation mechanism. The at least one actuation mechanism includes a substrate and a linkage assembly. The substrate is connected to a second circuit board and has at least one second guiding portion. The at least one second guiding portion is guided by the guide and fulcrum device. The linkage assembly includes an actuating rod pivotally disposed on the substrate by a pivot shaft. The actuating rod is pivotable between a first position and a second position and one end of the actuating rod abuts against the guide and fulcrum device. When the actuating rod is pivoted from the first position to the second position, the substrate is moved through the at least one second guiding portion along a guiding direction of the at least one guide and fulcrum device.
