Field-Upgradeable Barcode Reader with Interchangeable Camera Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bi-optic barcode readers are unable to provide non-barcode imaging data, limiting their functionality in monitoring the checkout process beyond barcode reading.
Innovation Solution
The development of field-upgradeable barcode readers that include a receptacle for interchangeable camera inserts, allowing for the capture of non-barcode data through a vertical window, with the ability to change camera orientation and field of view using 'fish eye' lenses, enabling the capture of image data for various applications such as building product databases and detecting fraudulent activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bi-optic barcode readers are designed with fixed imaging components, then the device structure is simple and reliable, but the functionality is limited to barcode reading only
Solution Approach 1:
The imaging system is segmented into separate functional modules: a fixed bi-optic barcode reading system and a removable camera module. This allows the barcode reader to maintain its simple core structure while optionally accepting additional imaging capabilities through interchangeable camera inserts that can be added or removed based on specific application needs.
Solution Approach 2:
The barcode reader is designed with universal adaptability by incorporating a receptacle that can accommodate different camera inserts with varying orientations and fields of view. This multi-functionality approach enables a single device to serve multiple purposes: standard barcode reading, non-barcode imaging data capture, and various monitoring applications, without requiring separate dedicated devices for each function.
2Adaptability or versatility
If camera inserts are made interchangeable and field-installable, then the adaptability and versatility are improved, but the device complexity and difficulty of manufacture increase
Solution Approach 1:
The system separates the camera module from the main barcode reader body, creating independent, standardized components. The receptacle is designed with a simple, repeatable interface that accepts pre-assembled camera inserts. This segmentation allows manufacturers to produce the barcode reader body and camera inserts separately using standardized processes, then assemble them through a straightforward insertion mechanism, reducing overall manufacturing complexity despite the added versatility.
3Adaptability or versatility
If multiple camera orientations and fields of view are supported, then the monitoring capabilities are enhanced, but the device complexity increases
Solution Approach 1:
Instead of incorporating multiple fixed optical paths for different camera orientations, the system uses a dynamic approach where a single receptacle accepts camera inserts that can be oriented differently. The optical path remains simple and fixed, but the camera insert orientation varies to provide different fields of view and monitoring angles, thereby enhancing monitoring capability without complicating the internal optical component arrangement of the main device.

AI summary
An example field-upgradeable barcode reader is configured to be supported by a workstation and includes a first housing portion supporting a generally horizontal platter having a generally horizontal window and a second housing portion supporting a generally vertical window. The second housing includes a receptacle configured to alternatively receive one of a cover and a field-installable imaging assembly insert. The field-installable imaging assembly insert is configured to receive an image acquisition assembly.
