Shopping Cart Bagging Station Coupler System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The need for bagging stations in retail stores has evolved with the rise of electronic purchasing and self-checkout, requiring a solution to allow customers to bag their purchases as they shop, rather than solely at checkout stations.
Innovation Solution
A shopping cart bagging station that includes a bag dispenser and a coupler system, where the bag dispenser holds and dispenses shopping bags, and the coupler secures the bagging station to the shopping cart, enabling customers to bag items conveniently as they shop, with the coupler system using a back plate and L brackets to clamp the cart securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bagging station is mounted in a shopping cart, then customers can bag purchases at any location in the store, but the device complexity increases due to the coupler system
Solution Approach 1:
The bagging station is divided into separate functional modules: a bag dispenser unit, a coupler system with L-brackets and back plate, and mounting hardware. This segmentation allows the system to be assembled and disassembled easily while maintaining adaptability to different shopping cart types.
Solution Approach 2:
The coupler system is designed with universal mounting capabilities that can attach to various shopping cart configurations. The L-brackets and back plate configuration allows the same basic design to work with different cart sizes and frame structures, making the bagging station adaptable across multiple cart types without requiring custom designs for each.
2Reliability
If a secure coupler system is used to attach the bagging station to the shopping cart, then the station remains stable during use, but the ease of manufacture decreases
Solution Approach 1:
The coupler system components (L-brackets, back plate, bolts) are pre-configured and pre-assembled into a complete mounting unit before final installation on the shopping cart. This preliminary assembly ensures proper alignment and secure attachment while simplifying the final installation process, as the entire coupler assembly can be mounted as a single unit rather than assembling multiple small components on-site.
3Ease of operation
If the bagging station is made portable by coupling it to a shopping cart, then customers can move it freely, but the reliability of secure attachment may be compromised
Solution Approach 1:
The coupler system utilizes the existing curved frame structure of shopping carts as part of its mounting geometry. The L-brackets are designed to interface with the tubular metal frames that characterize most shopping carts, using the natural curvature and shape of these frames to provide secure attachment points that maintain reliability while preserving mobility.

AI summary
A shopping cart bagging station that couples to a shopping cart is described. The shopping cart bagging station includes a bag dispenser and a shopping cart coupler. The bag dispenser holds a plurality of shopping bags, and dispenses the shopping bags one at a time as products are placed in a shopping bag. The shopping cart coupler is coupled to the bag dispenser and couples the shopping cart bagging station to a shopping cart. The shopping cart bagging station is coupled to a shopping cart by coupling the shopping cart coupler to the bag dispenser such that a side of the shopping cart is clamped between the shopping cart coupler and the bag dispenser. The shopping cart bagging station can be mounted in various locations on a shopping cart, making it easy and convenient for a customer to carry and load a number of shopping bags as they shop.
