Bioptic Barcode Reader Carrier Assembly for Easier Sealing and Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bioptic barcode readers have complex housing assemblies with multiple parts, leading to increased electrostatic discharge and dust ingress, complicated component access, and difficult assembly and servicing due to distributed components and cabling, requiring disassembly for testing and service.
Innovation Solution
A bioptic barcode reader design with a two-part housing (upper and lower housings) and a single carrier frame assembly for optical and electronic components, eliminating intermediate housings and removable covers, allowing for simplified sealing, easier assembly, and serviceable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional housing assemblies with three or more housing portions and various covers are used, then the barcode reader can be assembled with distributed optical and electronic components, but the number of electrostatic discharge, water, and dust paths increases, requiring a large number of seals and making sealing more difficult
Solution Approach 1:
The patent merges multiple housing portions and covers into a simplified two-part housing assembly (first housing and second housing). This consolidation reduces the number of interfaces and sealing locations from three or more to just two, directly addressing the sealing difficulty while maintaining the ability to house distributed optical and electronic components.
Solution Approach 2:
The patent segments the housing into exactly two portions (first housing and second housing) that can be separately assembled and then joined. This segmentation approach simplifies the assembly process while minimizing the number of seals required, as each housing portion can be pre-assembled with components before final joining.
2Device complexity
If traditional housing assemblies with three or more housing portions are used, then components can be distributed through housing sections, but access to optical and electronic components becomes more complicated with cabling passing between components and through all housing portions
Solution Approach 1:
The patent combines the housing structure into two parts, which simplifies the pathways for cabling and component access. With fewer housing portions to navigate, cables and service personnel have more direct access to components, reducing the complexity of routing through multiple sections.
3Ease of manufacture
If optical and electronic components are distributed and mounted to different housing sections, then the barcode reader can be assembled with separated components, but the entire barcode reader has to be assembled before it can be tested, requiring disassembly if a problem is found
Solution Approach 1:
The patent segments the housing into two separable portions, allowing components to be mounted within each housing section independently. This enables partial assembly and testing of individual housing portions before final integration, reducing the need for complete disassembly during servicing.
4Ease of repair
If traditional barcode readers are disassembled to service electronic components and printed circuit boards, then components can be accessed, but the risk of broken connectors increases
Solution Approach 1:
The patent merges the housing into two parts that can be separated for servicing and then reconnected. This controlled separation and reconnection process reduces the risk of connector damage compared to disassembling multiple small housing portions, as fewer connectors need to be handled and reconnected.

AI summary
Bioptic barcode readers are disclosed herein. An example bioptic barcode reader includes an upper housing and a lower housing secured directly to the upper housing, the lower housing and the upper housing defining an interior region. The upper housing includes a horizontally extending portion, an integral and unitary tower portion extending above the horizontally extending portion, a generally horizontal window positioned in the horizontally extending portion, and a generally upright window positioned in the tower portion. An imaging sensor, at least one intermediate mirror, at least one vertical output mirror, and at least one horizontal output mirror are positioned within the interior region.
