Resolving events in item-identifying carts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional shopping process in materials handling facilities is inefficient due to the need to manually retrieve items, place them in carts, and then transfer them to bags or carriers for checkout, which slows down the process and mitigates the advantages of using carts for transportation.
Innovation Solution
The introduction of item-identifying carts equipped with cameras and weight sensors that automatically identify items placed in or removed from the cart, determine the actions taken with these items, and update a virtual cart, allowing for seamless checkout without the need for manual scanning at a checkout stand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual item retrieval and transfer to bags is used, then users can transport items, but the process becomes slow and inefficient
Solution Approach 1:
The cart system performs automatic item identification and tracking without requiring user intervention at checkout. The cameras and weight sensors enable the cart to autonomously detect items placed in or removed from it, eliminating the need for manual scanning and bagging processes.
Solution Approach 2:
The patent replaces manual mechanical operations (hand-carrying items to checkout, manual scanning, manual bagging) with an automated optical and sensing system. Cameras capture images of items, weight sensors measure changes, and a processor automatically updates the virtual cart, substituting human labor with automated detection and data processing.
2Ease of operation
If traditional checkout process is used, then items can be scanned and bagged, but the process complexity increases
Solution Approach 1:
The patent merges the shopping cart with checkout functionality by integrating cameras, weight sensors, and a virtual cart system directly into the cart. This combines item collection, identification, tracking, and payment preparation into a single unified device, eliminating the need for separate checkout equipment and processes.
Solution Approach 2:
The cart system autonomously performs item identification, weight measurement, and virtual cart updates without requiring user interaction with checkout equipment. The system self-manages the entire checkout process from item detection to final payment preparation.
3Productivity
If manual item scanning at checkout stand is used, then items can be registered, but the process requires additional equipment and space
Solution Approach 1:
The patent transitions the checkout function from a stationary horizontal plane (checkout stand) to a mobile vertical dimension (handheld cart). The cart moves with the user through the facility, bringing the scanning and tracking capabilities directly to the items as they are collected, eliminating the need for dedicated checkout areas.
Solution Approach 2:
The cart serves as an intermediary device between the user and the checkout system. It captures item data via cameras and weight sensors, maintains a virtual cart, and communicates with the facility's inventory system, replacing the traditional role of the checkout stand as the intermediary between items and the payment system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution streamlines the shopping process by eliminating the need for manual item transfer and scanning, enabling users to efficiently select and checkout items directly from the cart, reducing the time and effort required for shopping and checkout.
Implementation Method 1
component(s) to receive image data generated by one or more cameras of the mobile cart, and analyze the image data to identify one or more items
Implementation Method 2
receive weight data generated by one or more weight sensors of the mobile cart, and determine an outcome of an event involving the identified item
Data Source
AI summary
This disclosure is directed to item-identifying carts that may be utilized by users to automatically identify items that the users place in their carts. In addition, these carts may automatically determine the outcome of respective events that occur with respect to these identified items. For example, the carts may be configured to identify one or more items that are placed into or removed from the cart, and thereafter determine one or more actions taken with respect to the identified items and a quantity of the items involved. For example, after identifying a first item and a second item either placed into or removed from the cart, the cart may determine that the user added two instances of the first item and removed one instance of the second item. In response to making this determination, the cart may update a virtual cart of a user operating the physical cart.
