Solution Overview

Problem

Existing inventory systems are limited by the need for on-site personnel, susceptibility to vandalism and theft, inefficient auditing, and the difficulty in moving and restocking due to centralized storage, posing risks for large items and hazardous materials.

Innovation Solution

An automated mobile inventory system integrated with a standardized shipping container, featuring modular storage locations, an order picking device, and a secured inventory portal subsystem with an operator station, enabling secure, mobile, and efficient inventory management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If centralized storage is used to ensure availability of stock, then stock availability is improved, but personnel travel time and retrieval efficiency deteriorate

Engineering Contradiction:

Improvestock availabilityVSAvoidpersonnel travel time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The inventory system is divided into multiple distributed modular units that can be placed at different job sites, eliminating the need for centralized storage and reducing personnel travel time while maintaining stock availability through local presence

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inventory system is designed to be mobile rather than fixed, allowing it to be transported to different job sites as needed. This dynamic positioning maintains stock availability at the point of use without requiring personnel to travel to a centralized location

Inventive Principle:

Principle #15Dynamics

2Reliability

If physical inventory room is established for secure storage, then security is improved, but susceptibility to vandalism, theft, and damage deteriorates

Engineering Contradiction:

ImprovesecurityVSAvoidvandalism, theft, and damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Physical security measures are replaced with electronic and automated systems including remote monitoring, electronic access control, and automated inventory management. This reduces vulnerability to physical vandalism and theft while maintaining security through technological means

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system incorporates automated monitoring and alerting capabilities that enable self-protection against theft and vandalism without requiring constant human presence, allowing the inventory system to defend itself through automated detection and notification

Inventive Principle:

Principle #25Self-service

3Ease of operation

If on-duty personnel are required for inventory management, then accessibility is improved, but operating time limitations and human error in auditing worsen

Engineering Contradiction:

ImproveaccessibilityVSAvoidoperating time limitations

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The inventory system performs automated auditing, tracking, and inventory management functions without human intervention. Sensors and RFID tags automatically monitor stock levels, track movements, and generate reports, eliminating operating time limitations and human error while maintaining continuous accessibility

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual inventory auditing and management by personnel is replaced with automated electronic systems including RFID tracking, weight sensors, and software management. This eliminates human error in auditing and removes operating time limitations while preserving accessibility

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of manufacture

If modular storage locations are used for mobile inventory, then ease of deployment is improved, but system complexity worsens

Engineering Contradiction:

Improveease of deploymentVSAvoidsystem complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

Standardized shipping containers serve multiple functions as both the structural housing and the mobile platform for inventory storage. This universal use of the container simplifies the overall system design while maintaining ease of deployment through standardized, off-the-shelf components

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An automated inventory system which enables secure and highly mobile inventory storage. The system comprises a standardized shipping container which houses a plurality of storage locations for storing inventory items in the shipping container. An order picking device is positioned inside the shipping container to move one or more selected inventory items, and a secured inventory portal subsystem is attached to a wall of the shipping container. The portal subsystem comprises an operator station for a user to order and collect the one or more selected inventory items through operation of the order picking device.
