Augmented Reality Wayfinding for Warehouse Item Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customers and shoppers often struggle to navigate warehouses efficiently due to varying layouts and find replacements for out-of-stock items, especially when potential replacements are not located near the original items.
Innovation Solution
A wayfinding application on a client device displays augmented reality elements to guide users to target items within a warehouse, identifies replacements if the target item is not found, and alerts users through augmented reality elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If customers navigate warehouses using traditional methods without assistance, then they can find items eventually, but navigation time and efficiency are reduced
Solution Approach 1:
The patent introduces an augmented reality wayfinding system that acts as an intermediary between the customer and the warehouse environment. The system uses a mobile device with camera, display, and processor to capture images of the warehouse, overlay directional arrows and item location indicators on the display, and guide customers to their destinations. This intermediary system resolves the contradiction by providing real-time visual guidance that reduces navigation time while maintaining ease of operation through intuitive AR interface.
Solution Approach 2:
The patent replaces traditional mechanical navigation methods (physical signage, manual asking for directions) with an optical/electronic system. The mobile device captures images through its camera, processes the images to identify aisles and item locations, and displays augmented reality overlays with directional arrows. This substitution of mechanical navigation with optical-electronic processing and display significantly reduces navigation time while maintaining user-friendly operation.
2Adaptability or versatility
If warehouse layouts vary between locations, then customization to local needs is achieved, but customer familiarity and navigation efficiency are reduced
Solution Approach 1:
The patent implements a dynamic wayfinding system that adapts to different warehouse layouts in real-time. Rather than relying on static maps or pre-programmed routes, the system captures current images of the warehouse environment, identifies aisles and item locations dynamically, and generates appropriate directional guidance. This dynamic adaptation allows the system to handle varied layouts across different warehouse locations while providing efficient navigation specific to each location's current configuration.
Solution Approach 2:
The patent changes the parameters of the navigation system based on the specific warehouse layout. The system adjusts its image processing parameters, aisle identification criteria, and directional arrow placement according to the captured warehouse environment. By changing these parameters dynamically rather than using fixed settings, the system adapts to different warehouse configurations while maintaining efficient navigation performance across various locations.
3Loss of information
If traditional navigation methods are used, then system complexity is low, but information accuracy and guidance precision are reduced
Solution Approach 1:
The patent creates a virtual copy of the warehouse environment by capturing images with the mobile device camera and overlaying digital indicators on the captured image. The augmented reality display shows directional arrows and item location markers that are superimposed on the actual warehouse view. This copying approach provides highly accurate item location information by directly mapping digital guidance elements to the physical environment, while the complexity is managed through software-based image processing rather than complex hardware systems.

AI summary
A wayfinding application executing on a client device receives a current location of the device within a warehouse and accesses a layout of the warehouse describing locations of items included among an inventory of the warehouse. The application identifies a route from the current location to one or more locations within the warehouse associated with one or more target items, generates augmented reality elements including instructions for navigating the route, and sends the elements to a display area of the device. The application detects a location within the warehouse associated with a target item and determines whether the item is at the location based on an image captured by the device. Upon determining it is not at the location, the application alerts a user of the device to a replacement item by generating an augmented reality element that calls attention to it and sending the element to the display area.
