Solution Overview
Problem
Tobacco retailers face challenges such as theft, improper sales to minors, and manual inventory tracking errors, which are time-consuming and prone to manipulation.
Innovation Solution
An electronically controlled and monitored dispensing cabinet with multiple chambers, a tracking system using light emitting and detection elements, and an electronic system for recording transactions, including a keypad for operator input and a storage device for inventory data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inventory tracking is used, then device complexity is reduced, but measurement precision and reliability of inventory data deteriorate due to errors and manipulation
Solution Approach 1:
The patent replaces manual mechanical inventory tracking with an automated optical detection system. Light emitting elements and light detection elements form an optical tracking system that automatically monitors tobacco product packages in chambers, eliminating human error and manipulation while maintaining relatively simple device architecture through non-contact optical sensing.
Solution Approach 2:
The system enables self-monitoring of inventory through automatic detection. The light emitting and detection elements continuously track package presence and quantity without requiring manual intervention, allowing the system to automatically update inventory records and alert when restocking is needed.
2Reliability
If electronically controlled dispensing is implemented, then theft prevention improves, but device complexity increases due to control and monitoring systems
Solution Approach 1:
The dispensing system is divided into separate functional modules: light emitting elements for active sensing, light detection elements for signal reception, control circuits for logic operations, and dispensing mechanisms for physical package release. This segmentation allows each component to perform its specific function simply, reducing overall system complexity while maintaining strong theft prevention through integrated electronic control and monitoring.
3Productivity
If real-time inventory monitoring is implemented, then productivity improves through automated tracking, but use of energy increases due to continuous operation of tracking systems
Solution Approach 1:
The light emitting elements and detection elements operate periodically rather than continuously. The system can be configured to scan inventory at regular intervals or trigger detection events based on specific conditions such as attempted access or time-based schedules, reducing energy consumption while maintaining real-time monitoring capability when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides accurate real-time inventory tracking, reduces theft, ensures compliance with sales restrictions, and streamlines restocking and reordering processes by automating the dispensing and monitoring of tobacco products.
Implementation Method 1
The tracking system is configured to track the number of tobacco product packages in each chamber as tobacco product packages are dispensed from the chambers and to include one or more light emitting elements and one or more light detection elements
Data Source
