Perforated PCB Modules with Recessed Conductive Tracks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printed circuit board (PCB) systems lack scalability and protection against short circuits when reduced in dimension, as the electrically conductive tracks become accessible to other parts, leading to potential undesired contact and functionality issues.
Innovation Solution
A printed circuit board design featuring a perforation line with a non-straight configuration, including projecting and recessed parts, that intercepts the electrically conductive track, allowing for customization into separable modules while maintaining electrical conductivity and reducing the risk of short circuits by making the track ends recessed, thus minimizing exposure to other conductive elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a scalable PCB system is implemented by reducing dimension, then smaller functional units can be obtained for better stock management, but the electrically conductive tracks become accessible to other parts causing potential short circuits
Solution Approach 1:
The PCB is divided into separable modules through a perforation line with projecting and recessed parts, allowing the board to be segmented into smaller functional units while maintaining electrical connectivity through the conductive track that bridges both areas
Solution Approach 2:
The recessed part creates a nested structure where one PCB area is partially inserted into another, providing mechanical interlocking and electrical connectivity while the projecting part extends outward to prevent contact with external conductive elements
2Adaptability or versatility
If the PCB is made separable into modules, then customization and scalability are improved, but the electrical connectivity between modules becomes more complex
Solution Approach 1:
The conductive track serves multiple functions simultaneously: it provides electrical connectivity between PCB areas, acts as a mechanical guide for alignment, and extends into the projecting part to provide environmental protection. This multi-functionality simplifies the overall design despite the modular separability
3Ease of operation
If the conductive track is made accessible for modular design, then separability is achieved, but protection against undesired contact is reduced
Solution Approach 1:
The perforation line features asymmetric projecting and recessed parts where the conductive track is strategically positioned to be accessible for separability on one side while the projecting part extends to provide protective coverage, creating an asymmetric structure that simultaneously achieves both separability and protection
