Electromechanical pusher assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retail stores face challenges in preventing theft of high-demand items from shelves, as current solutions either limit customer access or require additional labor, and there is a need for an effective time delay mechanism to deter theft without compromising product visibility or increasing labor costs.
Innovation Solution
A product dispenser system with a housing, pusher, and feed device that includes a sensor to control the movement of products with a time delay, ensuring only one item is accessible at a time, thereby deterring theft by introducing a delay between the dispensing of subsequent items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple items are kept accessible on the shelf, then customer convenience and product visibility are improved, but the risk of theft increases
Solution Approach 1:
The system performs preliminary action by automatically advancing the next item forward in the sequence before a customer can reach for it. The sensor detects when an item is removed and immediately triggers the pusher mechanism to bring the next item into the accessible position, preventing thieves from grabbing multiple items simultaneously while maintaining continuous customer access
Solution Approach 2:
The pusher assembly acts as an intermediary mechanism between the stored items and the customer. It controls the release and movement of items one at a time, mediating access to prevent theft while still allowing legitimate customers to obtain products. The sensor-pusher system serves as an automated intermediary that monitors and regulates item distribution
2Object-affected harmful factors
If products are placed behind the counter or under lock and key, then theft is prevented, but labor costs increase and customer self-service is reduced
Solution Approach 1:
The system enables self-service by automating the item advancement mechanism. Sensors automatically detect when an item is removed and trigger the pusher to advance the next item without requiring customer assistance or staff intervention. This maintains product accessibility while preventing theft through automated control
Solution Approach 2:
The patent replaces manual mechanical control (staff monitoring and manual item release) with an automated sensor-actuated mechanical system. The sensor detects item removal and automatically activates the pusher mechanism, substituting human labor with an automated electromechanical system that prevents theft while maintaining customer access
3Object-affected harmful factors
If a time delay mechanism is implemented, then theft is deterred, but device complexity increases
Solution Approach 1:
The system implements preliminary action by having the sensor continuously monitor and the pusher pre-positioned to advance items. When theft is detected (multiple items removed in quick succession), the system has already been prepared to control item release, creating an automatic time delay without requiring complex processing or multiple mechanical stages

AI summary
A product dispenser defines a product dispensing path and includes a housing, a pusher, a driver, and a controller. The housing extends along the product dispensing path. The pusher is configured to translate along the product dispensing path. The driver is operably coupled to the pusher and configured to urge the pusher along the product dispensing path. The controller is in communication with the driver and operable to activate the driver to urge the pusher along the product dispensing path after a threshold period of time.
