PCB Connector Shaped Element for Reliable Optical Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printed circuit board connectors in dark colors are difficult to detect for optical sensors, such as cameras, due to their fine contours and holding elements, which hinders precise and reliable registration by automated component applicator devices.
Innovation Solution
A detectable shaped element is integrated into or attached to the housing of the printed circuit board connector, featuring a simple geometric shape like triangles, polygons, or semicircles, and highlighted with contrast elements or markings for easy identification by sensors, ensuring precise positioning and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional dark-colored housings are used for printed circuit board connectors, then manufacturing simplicity and cost-effectiveness are maintained, but detection precision by optical sensors deteriorates
Solution Approach 1:
The patent applies color changes by adding a contrast element with a different color than the housing base color. The contrast element creates optical contrast that enables sensor systems to reliably detect the connector's position and orientation, while the housing itself maintains its conventional dark color for manufacturing simplicity.
Solution Approach 2:
The contrast element acts as an intermediary between the housing and the sensor system. Instead of modifying the entire housing to improve detection, a small dedicated contrast element is added as a mediator that provides the necessary optical contrast for sensor detection without changing the housing's fundamental manufacturing process.
2Device complexity
If conventional single-color housings are used, then manufacturing complexity is minimized, but detection reliability by automated component applicator devices deteriorates
Solution Approach 1:
The patent introduces a contrast element with a color that differs from the housing base color. This simple color differentiation provides sufficient visual contrast for sensor systems to reliably detect the connector, without requiring complex structural modifications to the housing.
Solution Approach 2:
The housing is segmented into two functional parts: the base housing structure that provides mechanical support and connection functions, and the contrast element that provides detection functionality. This segmentation allows each part to be optimized independently for its specific function.
