Barcode Scanner Connector Orientation for Flush Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bar code scanners often face challenges in mounting due to limited space behind the scanner, as rearwardly projecting connectors obstruct proper placement in retail checkout counters.
Innovation Solution
A box-shaped scanner housing with a recess in the rear portion featuring sockets oriented parallel to the scan window plane, allowing connectors to be positioned in a 'T' or 'Y' configuration, reducing the need for perpendicular space and facilitating efficient cable routing with optional routing members for strain relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connectors are positioned to project outward from the back of the scanner perpendicular to the window plane, then power and data connections can be made to the scanner, but the rearwardly projecting connectors obstruct proper placement in retail checkout counters due to limited space behind the scanner
Solution Approach 1:
The patent repositions the connectors from projecting perpendicular to the window plane (rearward direction) to projecting parallel to the window plane (lateral direction). This dimensional change in connector orientation allows cables to exit the scanner housing from the sides rather than the back, eliminating the space obstruction problem while maintaining connection functionality.
2Area of stationary object
If connectors are repositioned to project parallel to the scan window plane from opposing rearward walls, then space behind the scanner is conserved and flush mounting is enabled, but the connector arrangement becomes more complex with sockets positioned in opposing walls
Solution Approach 1:
The patent divides the connector arrangement into two separate socket assemblies positioned in opposing rearward walls of the housing. Each socket assembly is independently positioned and oriented, allowing cables to enter from opposite directions. This segmentation enables the complex lateral connection arrangement to be implemented while maintaining modularity and ease of assembly.
3Reliability
If cables are routed through the recess formed in the rear portion of the housing, then cable management is improved and strain relief is enhanced, but the housing structure becomes more complex with additional recess features
Solution Approach 1:
The patent creates a recess structure within the housing that contains and organizes the cable routing path. The recess is nested within the housing walls, providing a dedicated channel for cable passage. This nested structure protects cables from external forces and organizes the wiring space, improving reliability while the recess integration keeps the overall housing compact.

AI summary
A bar code scanner is configured for placement in a retail checkout counter. The barcode scanner includes a box-shaped scanner housing to be received by the checkout counter. The box-shaped scanner housing includes a front portion and a rear portion with a recess formed in the rear portion. The recess includes two opposing walls oriented substantially perpendicular to the scanner window plane. A first socket is positioned in a first of the two opposing walls of the recess. A second socket is positioned in a second of the two opposing walls of the recess. The first socket is oriented to receive a first connector in a direction that is different from a direction perpendicular to the window plane. The second socket is oriented to receive a second connector in a direction that is opposite the first direction.
