Horizontal Capacitor Module Layout for Compact PCB Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrolytic capacitors mounted vertically on printed circuit boards (PCBs) lead to significant wasted mounting space, limiting the integration density and increasing the physical size of electronic devices due to their size and orientation.
Innovation Solution
Horizontally mounting electrolytic capacitors on PCBs using a case with electrode pads and a frame that surrounds the capacitor, allowing for reduced vertical space occupation and improved integration density through automated manufacturing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrolytic capacitors are mounted vertically on PCBs, then the mounting process is simple and straightforward, but the vertical space occupation increases significantly, reducing integration density
Solution Approach 1:
The patent transitions the capacitor mounting orientation from vertical to horizontal, changing the dimension in which the capacitor occupies space. By mounting the capacitor horizontally on the PCB surface, the vertical profile is minimized while the horizontal footprint is optimized, effectively resolving the contradiction between mounting simplicity and vertical space occupation.
2Ease of manufacture
If electrolytic capacitors are mounted vertically on PCBs, then the electrical connections are straightforward, but the overall device size increases due to wasted mounting space
Solution Approach 1:
The patent changes the mounting dimension from vertical to horizontal, allowing the capacitor to be positioned within the PCB's planar area rather than extending vertically. This dimensional change reduces the overall device volume while maintaining electrical connection simplicity through the electrode pad configuration.
3Device complexity
If conventional vertical mounting is used, then the capacitor structure is simple, but the integration density is limited due to size constraints
Solution Approach 1:
The patent resolves the contradiction by changing the mounting orientation from vertical to horizontal, which optimizes the use of available PCB area. This dimensional change allows for better space utilization and improved integration density while maintaining a relatively simple capacitor structure with electrode pads configured for horizontal mounting.
