Solution Overview

Problem

Businesses face challenges in maintaining optimal shelf inventory levels to maximize sales rates, as existing methods fail to accurately predict when restocking is needed to prevent stock depletion or overflow, leading to decreased sales.

Innovation Solution

A system utilizing cameras, sensors, and sales data to create and update a rate of sales model that generates a restocking schedule based on real-time inventory levels, adjusting for factors like product location, day of the week, weather, and customer demographics, to maintain desired sales rates by predicting optimal inventory thresholds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If real-time inventory monitoring and dynamic restocking scheduling are implemented, then sales rate is improved, but device complexity increases

Engineering Contradiction:
Improvesales rateVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables self-service through automated inventory monitoring and dynamic restocking scheduling. The server automatically receives inventory data from cameras and sensors, updates the rate of sales model, generates restocking schedules, and sends notifications to mobile devices without human intervention, allowing the system to manage itself and eliminate manual inventory tracking

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical inventory checking with automated optical and sensor-based detection. Cameras and sensors automatically capture shelf inventory data, substituting human visual inspection with electronic detection systems that continuously monitor and transmit data to the server for processing

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

2Loss of time

If manual inventory checking is performed, then device complexity is reduced, but loss of time increases

Engineering Contradiction:
Improvetime for inventory managementVSAvoidsystem complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system achieves continuous inventory monitoring through cameras and sensors that operate continuously or at regular intervals, capturing shelf data in real-time. This continuous action eliminates the discontinuous, periodic nature of manual checking, ensuring inventory status is always current without requiring repeated human intervention

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

Manual mechanical inventory checking is replaced with automated electronic detection systems including cameras and sensors that continuously capture and transmit inventory data to the server, eliminating the time-consuming manual process of physically counting and recording stock levels

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

3Productivity

If static restocking schedules are used, then device complexity is reduced, but sales rate deteriorates

Engineering Contradiction:
Improvesales rateVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system transitions from static, pre-determined restocking schedules to dynamic schedules that automatically adapt based on real-time inventory data and actual sales performance. The rate of sales model is continuously updated with new data, and restocking schedules are regenerated to reflect current conditions, optimizing sales opportunities as they arise

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback loops where inventory data and sales transactions are continuously collected, the rate of sales model is updated based on this feedback, and restocking schedules are adjusted accordingly. This closed-loop system ensures restocking decisions are based on actual performance data rather than static predictions

Inventive Principle:
Principle #23Feedback

AI summary

In various examples, a system identify a first issue object associated with the alert by making a first set of determinations, based on an alert of an active issue of a system resource. Additionally, the system can determine whether the active issue associated with the first issue object can be automatically corrected by one or more self-healing processes, based on the first issue object. Moreover, the system can implement the one or more self-healing processes, based on determining that the active issue associated with the first issue object can be automatically corrected by one or more self-healing processes.
