Payment Terminal Camera Nesting in Card Reader Overhang
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic payment terminals face challenges in achieving compactness while maintaining the reliability of magnetic card readers and cameras, as the space requirements for optimal card guidance and camera functionality often conflict.
Innovation Solution
The integration of a horizontal magnetic card reader and front/rear cameras in an electronic payment terminal, where the card reader is positioned above the screen and the camera is integrated below the card passage, optimizing compactness without compromising performance, and allowing for distinct vision angles and flexible placement on a single printed circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic card reader with a card passage is integrated into the electronic payment terminal, then magnetic card reading functionality is provided, but the terminal size increases due to space requirements for optimal card guidance
Solution Approach 1:
The card passage is configured to extend in a plane substantially parallel to the top face of the terminal, with the bottom wall extending beyond the top wall to create an overhang. This dimensional arrangement allows the camera to be positioned in the overhanging region, utilizing space that would otherwise be wasted and eliminating the need for additional terminal volume.
Solution Approach 2:
The camera is integrated within the space created by the overhanging bottom wall of the card passage. The camera housing is positioned in the region where the bottom wall extends beyond the top wall, effectively nesting the camera within the card reader structure rather than adding separate space.
2Adaptability or versatility
If a front camera is integrated into the electronic payment terminal for barcode reading, then barcode scanning capability is provided, but the terminal size increases due to space requirements for camera placement
Solution Approach 1:
The camera is integrated within the space created by the overhanging bottom wall of the card passage. The camera housing is positioned in the region where the bottom wall extends beyond the top wall, effectively nesting the camera within the card reader structure rather than adding separate space.
Solution Approach 2:
The card passage is configured to extend in a plane substantially parallel to the top face of the terminal, with the bottom wall extending beyond the top wall to create an overhang. This dimensional arrangement allows the camera to be positioned in the overhanging region, utilizing space that would otherwise be wasted and eliminating the need for additional terminal volume.
3Adaptability or versatility
If both magnetic card reader and front camera are integrated into the electronic payment terminal, then multiple payment options are provided, but the terminal size increases due to cumulative space requirements
Solution Approach 1:
The camera and magnetic card reader are merged into a single integrated structure. The camera is positioned within the overhanging region of the card passage, combining two functional elements into one compact unit that provides both magnetic card reading and barcode scanning capabilities without cumulative space increase.
Solution Approach 2:
The card passage is configured to extend in a plane substantially parallel to the top face of the terminal, with the bottom wall extending beyond the top wall to create an overhang. This dimensional arrangement allows the camera to be positioned in the overhanging region, utilizing space that would otherwise be wasted and eliminating the need for additional terminal volume.
4Measurement precision
If the camera is positioned to have optimal vision cone for barcode reading, then scanning accuracy is improved, but the terminal thickness increases
Solution Approach 1:
The card passage is configured to extend in a plane substantially parallel to the top face of the terminal, with the bottom wall extending beyond the top wall to create an overhang. This dimensional arrangement allows the camera to be positioned in the overhanging region, utilizing space that would otherwise be wasted and eliminating the need for additional terminal volume.
