Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current checkout terminals in retail stores face challenges in efficiently handling customers with many items, leading to long delays and reduced throughput, which can be exacerbated during busy periods, and there is a need to optimize the use of floor space for increased efficiency and environmental benefits.
Innovation Solution
A modular checkout terminal design featuring a U-shaped or S-shaped delivery path with multiple packing stations arranged parallel to each other, a loading conveyor section, a scanning section, and a transfer conveyor section, equipped with product diversion units and conveyor belts, allowing for efficient routing and allocation of packing stations to increase customer throughput while maintaining a compact footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single packing station is used in the checkout terminal, then the device complexity is reduced, but the customer throughput and productivity are limited
Solution Approach 1:
The checkout terminal is segmented into multiple packing stations (first, second, and third packing stations) that are spatially separated and arranged in parallel. Each packing station operates independently to receive products from the transfer conveyor, allowing multiple customers to pack simultaneously and thereby increasing throughput without requiring a single complex centralized packing area.
Solution Approach 2:
The packing stations are arranged in a spatial configuration that utilizes the third dimension (depth) of the terminal structure. The first and second packing stations are positioned at different longitudinal locations, with the third packing station accessible via a rear access point. This spatial distribution allows parallel operations without increasing the horizontal footprint, resolving the contradiction between throughput and device complexity.
2Productivity
If multiple packing stations are provided in parallel, then customer throughput is increased, but the floor space requirement increases
Solution Approach 1:
The checkout terminal employs a nested configuration where the transfer conveyor section runs transversely through the structure, and packing stations are arranged along its length. The first packing station is positioned at one end, the second packing station at the opposite end, and the third packing station is accessible through a rear access point that penetrates through the terminal structure. This nesting allows multiple packing stations to share the same horizontal footprint by utilizing different access points and spatial layers.
Solution Approach 2:
The terminal design utilizes the depth dimension by arranging packing stations at different longitudinal positions and providing rear access to the third packing station. This vertical and depth-based arrangement allows multiple packing stations to be packed into a compact horizontal footprint, increasing throughput without proportionally increasing floor space requirements.
3Productivity
If the transfer conveyor section is arranged transversely perpendicular to loading and packing stations, then product routing efficiency is improved, but the device complexity increases
Solution Approach 1:
The transfer conveyor section is pre-configured in a transverse arrangement that is perpendicular to both the loading conveyor section and the packing stations. This preliminary spatial configuration establishes efficient product routing paths from the loading area through the scanning section to the respective packing stations, minimizing the need for complex real-time routing adjustments and reducing operational complexity.

AI summary
A checkout terminal for customers in a retail store. The terminal provides a path for products from a loading conveyor section, via a scanning section and a common transfer conveyor section, to reach a respective one of a plurality of plurality of packing stations to be bagged or packed by or for the customer. Conveniently, three of these packing stations are arranged substantially parallel to each other. Each packing station may be associated with a corresponding payment interface. Customer throughput is increased by providing multiple packing areas associated with one loading and scanning area, and customer convenience is improved by the faster and more efficient configuration of the checkout terminal.
