Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional inventory tracking on store shelves is labor-intensive, prone to errors, and inefficient, leading to underutilization of shelf space and inaccurate planogram conformance due to manual data collection and reliance on human operations.

Innovation Solution

Implementing intelligent racks with circuit boards, processors, and network interfaces that electronically track and map product information, including UPCs, and a master controller for precise inventory management and planogram adherence, providing real-time alerts for incorrect product placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual inspection and counting methods are used to track inventory, then device complexity is low, but productivity is reduced and measurement precision deteriorates

Engineering Contradiction:

Improveinventory tracking efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The intelligent rack automatically performs inventory tracking functions without human intervention. Sensors detect product presence and automatically update inventory records, eliminating the need for manual counting while maintaining high productivity and accuracy.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual mechanical counting methods are replaced with electronic sensing systems. Optical sensors and RFID readers automatically detect and track products, substituting human labor with automated electronic systems that provide continuous, accurate inventory data.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If manual inventory tracking is performed, then device complexity remains low, but measurement precision and reliability deteriorate due to human error

Engineering Contradiction:

Improveinventory data accuracyVSAvoidtracking system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

Human visual inspection and manual recording are replaced with automated optical sensors and image recognition systems. These electronic systems objectively detect product characteristics and inventory levels without human error, providing precise and reliable measurement data.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system continuously monitors inventory levels and automatically compares actual stock against planned quantities. When discrepancies are detected, the system provides real-time feedback alerts to staff, enabling immediate correction of placement errors and maintaining high measurement precision.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If frequent manual audits are conducted to ensure planogram conformance, then measurement precision improves, but loss of time and productivity worsen

Engineering Contradiction:

Improveplanogram conformance accuracyVSAvoidaudit time consumption

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The intelligent rack continuously monitors product placement and inventory levels in real-time, eliminating the need for periodic manual audits. This continuous automated monitoring maintains high planogram conformance accuracy without interrupting store operations or consuming audit staff time.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

Manual planogram verification processes are replaced with automated image capture and analysis systems. Cameras mounted on racks continuously capture shelf images, and software automatically compares product placement against planogram requirements, providing precise conformance measurement without time-consuming manual inspection.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If manual inventory tracking is used, then ease of operation is maintained with simple procedures, but reliability and measurement precision deteriorate

Engineering Contradiction:

Improveinventory tracking reliabilityVSAvoidoperational simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The intelligent rack system automatically performs all inventory tracking functions without requiring staff intervention. The system self-monitors stock levels, detects placement errors, and maintains accurate records, providing high reliability while requiring minimal operational input from store employees.

Inventive Principle:

Principle #25Self-service

AI summary

A system includes a plurality of racks each storing packs of cigarettes, a display device associated with each rack and a master controller coupled to the racks and the display devices. A processor of the master controller is configured to receive a first indication that a scanner has scanned a first code associated with a first rack of the plurality of racks while the scanner is in a product checking mode. In response, the processor obtains from a memory a first rack number of the first rack and a first UPC associated with the rack number based on a planogram. The processor subsequently receives a second UPC scanned by the scanner of a pack actually stored in the first rack. Based on determining that the first and second UPCs do not match, the processor transmits an alert message indicating incorrect product placement in the first rack.
