Problem

Manual inspection of product storage facilities is time-consuming and increases operational costs due to the large number of shelves and products, necessitating a more efficient inventory management system.

Innovation Solution

Implementing a system with a trained machine learning model and image capture device to automatically process images of product storage areas, categorizing images into groups based on product recognition, and using a control circuit to retrain the model for improved accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual inspection is used to inventory products, then workers can identify and categorize products, but the process is time-consuming and increases operational costs

Engineering Contradiction:
Improveinventory accuracyVSAvoidinspection time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the mechanical manual inspection system with an automated image processing system. Image capture devices capture images of product storage areas, and machine learning models automatically analyze these images to identify products, count quantities, and update inventory records, eliminating the need for manual visual inspection while maintaining or improving inventory accuracy

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

Solution Approach 2:

The system enables self-service inventory management where the automated image processing system continuously monitors and updates inventory without human intervention. The machine learning models automatically detect products, recognize them from training data, and update database records, allowing the inventory system to service itself rather than requiring manual worker involvement

Inventive Principle:
Principle #25Self-service

2Measurement precision

If manual inspection is used to inventory products, then workers can identify products, but operational costs increase significantly

Engineering Contradiction:
Improveinventory accuracyVSAvoidoperational cost
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The patent replaces the mechanical manual inspection system with an automated image processing system. Image capture devices capture images of product storage areas, and machine learning models automatically analyze these images to identify products, count quantities, and update inventory records, eliminating the need for manual visual inspection while maintaining or improving inventory accuracy

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

Solution Approach 2:

The system uses feedback loops where the machine learning models continuously learn from new images and update their recognition capabilities. The control circuit receives feedback about product identification accuracy and adjusts the models accordingly, improving operational efficiency over time while reducing the need for manual verification and associated labor costs

Inventive Principle:
Principle #23Feedback

3Productivity

If automated image processing is implemented, then manual labor is reduced, but system complexity increases

Engineering Contradiction:
Improveinventory management efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent employs a universal machine learning model that can identify multiple types of products across different storage areas using a single trained system. The model is trained on diverse product images and can generalize to recognize various products, eliminating the need for separate specialized systems for different product categories and reducing overall system complexity

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

Solution Approach 2:

The system creates a digital copy of the physical inventory through image capture and stores it in a database. The machine learning models work with these digital representations rather than physically manipulating products, simplifying the system architecture. The control circuit manages these digital copies and uses them to update inventory records, reducing the complexity compared to direct physical inventory management

Inventive Principle:
Principle #26Copying
