Bioptic Reader Assembly Layout for Integrated Video Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bioptic reader assemblies lack sufficient space within the lower portion of the housing for integrating a video processing module and routing required cables, hindering the implementation of machine vision capabilities for object recognition and anti-shrink applications.
Innovation Solution
Position the video processing module within the upper portion of the housing, utilizing a separate decoder module and multiple imaging assemblies to capture and process image data for both indicia decoding and vision processing, with cables routed through the top portion to facilitate efficient integration and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the video processing module is integrated into the lower portion of the housing, then the barcode reading function can be maintained, but there is insufficient space for the video processing module and cable routing
Solution Approach 1:
The patent relocates the video processing module from the lower portion to the upper portion of the housing, utilizing the previously underutilized upper space. This dimensional relocation resolves the space conflict by exploiting the vertical dimension of the housing structure, allowing both barcode scanning and video processing functions to coexist without interference.
2Adaptability or versatility
If the video processing module is added to enable machine vision capabilities, then object recognition and anti-shrink applications become possible, but the device complexity and cable routing difficulty increase
Solution Approach 1:
The patent extracts the video processing module as a separate, independent component located in the upper portion, distinct from the barcode scanning subsystem in the lower portion. This separation allows each module to have dedicated cable routing paths, reducing overall system complexity and making installation and maintenance easier.
3Adaptability or versatility
If multiple imaging assemblies are integrated for both indicia decoding and vision processing, then functional versatility is improved, but the device complexity increases
Solution Approach 1:
The patent divides the imaging system into two separate segments: a first imaging assembly for barcode/indicia decoding positioned in the lower portion, and a second imaging assembly for video processing positioned in the upper portion. Each assembly is independently optimized for its specific function, with separate processing modules, reducing the complexity of integrating multiple functions into a single system.

AI summary
A bioptic indicia reader assembly includes a housing with a bottom portion and a top portion, each containing respective windows. A platter with an optically transmissive window aligns with the bottom-portion window. The assembly features a decoder module for decoding indicia from image data and a separate video processing module (VPM) for processing video streams. The VPM is strategically positioned within the top portion of the housing. The assembly includes a first imaging assembly capturing image data for the decoder module and a second imaging assembly capturing image data for the VPM, each extending through the respective windows. The top portion of the housing may include separate compartments for optical components and the VPM, with environmental sealing and heat dissipation features. The VPM is configured for various machine vision tasks, enhancing the functionality of the bioptic indicia reader in retail and other applications.
