Dynamic Store Feedback System for Navigation Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In retail environments, particularly grocery stores, workers face challenges in locating items on shopping lists accurately and efficiently, leading to customer dissatisfaction and slower fulfillment times due to outdated or incorrect product location information.
Innovation Solution
A dynamic store feedback system using a network of feedback devices such as electronic shelf labels (ESLs), computer vision monitoring, and sensor-based navigation to provide real-time, user-specific guidance to customers and workers, updating their routes and tasks based on current inventory and user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If workers manually locate items using traditional methods, then they can fulfill orders, but navigation accuracy is poor and errors increase
Solution Approach 1:
The system implements real-time feedback through electronic shelf labels that provide workers with accurate item location information. The feedback loop continuously updates workers on the correct positions of items, allowing them to navigate efficiently and locate products without error. This resolves the contradiction by providing precise navigation guidance while maintaining high reliability in item location.
Solution Approach 2:
The patent replaces manual mechanical search methods with an automated electronic guidance system. Instead of workers physically searching through shelves and aisles, the system uses electronic shelf labels and digital interfaces to guide them directly to items. This substitution of mechanical search with electronic guidance improves both navigation accuracy and reduces location errors.
2Reliability
If workers spend more time searching for items, then they can ensure accuracy, but fulfillment time increases
Solution Approach 1:
The system performs preliminary action by pre-calculating and displaying the correct item locations before workers arrive at shelves. Electronic shelf labels are updated in advance with accurate position information, allowing workers to navigate directly to items without searching. This preliminary preparation ensures both accuracy in item selection and reduces fulfillment time.
Solution Approach 2:
Real-time feedback through the electronic shelf label system provides workers with immediate confirmation of item locations and selection accuracy. The system continuously monitors and updates workers on their progress and any location corrections needed, ensuring accurate item selection while maintaining fast fulfillment speeds through efficient guidance.
3Productivity
If the store uses static product location information, then the system is simple to maintain, but navigation efficiency decreases due to outdated information
Solution Approach 1:
The system transitions from static product location information to dynamic real-time updates through electronic shelf labels. The labels automatically refresh with current item positions based on inventory management data, ensuring navigation efficiency is maintained even as product locations change. This dynamic approach improves productivity while the automated update mechanism manages system complexity.
Solution Approach 2:
The electronic shelf label system performs self-service by automatically updating product location information without manual intervention. The system integrates with inventory management databases to autonomously refresh label data, improving navigation efficiency through current information while reducing the operational complexity of manual updates. The system serves itself by automatically synchronizing location data across all labels.
