Solution Overview

Problem

The inefficiency of retail inventory storage systems that occupy valuable floor space in retail stores, leading to reduced space for customer navigation and product display.

Innovation Solution

Implementing a rack system positioned above the dropdown ceiling of a retail store, utilizing unmanned vehicles to transport reusable totes containing products through a rail system, and accessing products via access stations strategically placed throughout the store.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If inventory is stored in a back storage area, then storage capacity is provided, but valuable floor space is occupied reducing customer navigation and product display area

Engineering Contradiction:
Improveinventory storage capacityVSAvoidfloor space for customer navigation and product display
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent moves inventory storage from the horizontal plane (floor space) to the vertical dimension by installing racks above the dropdown ceiling. This dimensional transition allows the store to maintain full floor space for customer activities while creating substantial storage capacity in the previously unused overhead space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If a rack system is positioned above the dropdown ceiling, then floor space is freed for customer use, but complexity of the storage and retrieval system increases

Engineering Contradiction:
Improvefloor space availabilityVSAvoidrack system and retrieval mechanism complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The system employs autonomous unmanned vehicles that autonomously navigate the rail network, locate products via barcode scanning, and transport inventory to designated locations. This self-service capability eliminates the need for manual retrieval operations, making the complex automated system operate with minimal human intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical retrieval operations with an automated electromechanical system. Unmanned vehicles equipped with sensors, motors, and control systems substitute for human workers physically retrieving products, transforming a simple manual process into an automated intelligent system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If unmanned vehicles are used to transport products, then retrieval efficiency is improved, but device complexity and initial investment increase

Engineering Contradiction:
Improveinventory retrieval efficiencyVSAvoidunmanned vehicle and control system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The unmanned vehicles are designed as multi-functional units that can perform various tasks including product retrieval, transportation, inventory tracking via barcode scanning, and autonomous navigation. This universality allows a single system design to handle diverse inventory management operations, reducing the need for multiple specialized systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)
