Solution Overview

Problem

Retail locations face inefficiencies in product flow due to time lost in processing and locating products during restocking, as existing systems lack effective methods for accurate and rapid identification of storage locations and product tracking.

Innovation Solution

A system utilizing reconfigurable rope lights with RFID technology to visually indicate storage locations, combined with RFID scanners and control circuits, which illuminate specific light sources to guide users to the correct storage or retrieval of products, and can be updated automatically when product locations change.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If manual product location identification is used, then associates can find products, but time is lost in processing and locating products during restocking

Engineering Contradiction:
Improvetime lost in processing and locating productsVSAvoidoperational efficiency in restocking
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

The patent uses color-coded labels and visual indicators on storage locations and products to enable rapid identification. Different colors indicate different product categories, storage zones, or status, allowing associates to quickly locate items without manual searching or complex system navigation.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The system introduces an intermediary visual indication system between the inventory management database and the physical storage locations. This intermediary layer provides immediate visual feedback about product locations, reducing the cognitive load and time required for associates to translate digital information into physical navigation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If traditional inventory tracking methods are used, then product flow can be managed, but accurate and rapid identification of storage locations is lacking

Engineering Contradiction:
Improveaccuracy of storage location identificationVSAvoidcomplexity of inventory tracking system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The storage facility is divided into clearly defined zones, aisles, and locations, each with unique visual identifiers. This segmentation creates a hierarchical structure that simplifies navigation and reduces errors, as associates can progressively narrow down locations from zone to aisle to specific shelf position.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Storage locations are pre-labeled and organized according to a standardized system before products are placed. This preliminary organization ensures that when products need to be located or restocked, the path to the correct location is already established and visible, eliminating the need for complex real-time searching or calculation.

Inventive Principle:
Principle #10Preliminary action

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

AI summary

In some embodiments, apparatuses and methods are provided herein useful for product storage location identification. Reconfigurable lights can be mounted to product storage locations and one or more of the lights can be illuminated to identify a particular storage location, such as for placement or pick up of a product. The system described herein can utilize radio-frequency identification (RFID) chips or tags to identify products and storage locations. So configured, the system can identify which storage location a particular product is in or can identify where a particular product should be placed.
