Barcode Reader Assembly Retractable Lift Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Barcode reader and barcode reader assemblies with metal frames and/or scale assemblies are difficult to move, maneuver, install, and uninstall due to their size and weight, and existing lift mechanisms are inadequate in providing balance and assistance with lifting and balancing.
Innovation Solution
A barcode reader assembly with retractable lift handles having elongated apertures on both sides of the housing, allowing for a full-hand grip and positioning over the center of gravity, facilitating balanced lifting and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a barcode reader assembly with metal frame and scale assembly is used, then the functionality and durability are improved, but the weight and difficulty to move and install increase
Solution Approach 1:
The patent introduces lift handles as intermediary components that facilitate the movement and installation of the heavy barcode reader assembly. These handles act as mediators between the user and the heavy assembly, providing mechanical advantage and ergonomic grip points to overcome the weight barrier without compromising the metal frame and scale assembly functionality
2Ease of operation
If existing small hook lift mechanisms are used, then the device complexity is reduced, but the ease of operation and lifting assistance are insufficient
Solution Approach 1:
The lift handles are designed to be retractable, allowing them to extend during lifting operations and retract when not in use. This dynamic configuration provides lifting assistance when needed while maintaining a compact profile during normal operation, effectively balancing ease of operation with device complexity
Solution Approach 2:
The lifting function is segmented from the main barcode reader body through separate, movable handle components. This segmentation allows the lifting mechanism to be independently optimized for ease of operation while remaining a detachable or retractable feature that doesn't permanently increase the core device complexity
3Ease of operation
If narrow lift mechanisms covering small area are used, then the device complexity is minimized, but the balance and center of gravity control are insufficient
Solution Approach 1:
The lift handles are designed with elongated apertures that serve multiple functions: providing grip points for lifting, acting as balance control points aligned with the center of gravity, and serving as structural attachment points. This multi-functionality achieves balance control without adding separate dedicated components, thereby minimizing device complexity
4Adaptability or versatility
If barcode reader assemblies with various frame sizes and scale assemblies are offered, then the adaptability and versatility are improved, but the weight and center of gravity variability increase making lifting and balancing difficult
Solution Approach 1:
The retractable nature of the lift handles allows them to be positioned optimally for each specific assembly configuration. Regardless of the frame size or scale assembly variation, the handles can be extended and positioned to align with the specific center of gravity of that configuration, maintaining ease of lifting and balancing across all versatile options

AI summary
Barcode readers and barcode reader assemblies with lift handles are disclosed herein. An example bioptic barcode reader assembly includes a barcode reader having a housing and a metal frame secured to the housing. A retractable first lift handle having an elongated first aperture is positioned on a first side of the housing and a retractable second lift handle having an elongated second aperture is positioned on a second side of the housing, opposite the first side. Each of the first and second lift handles is movable relative to the housing between a retracted position and an extended position and the first and second apertures in the first and second lift handles overlie a first center of gravity of the barcode reader and a second center of gravity of the barcode reader assembly.
