Retail Display Module With Self-Contained Alarm and Product Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for retail displays face challenges in maintaining power for items like digital cameras and MP3 players, as internal batteries drain, and multiple modules connected to a central system complicate alarm identification and maintenance.
Innovation Solution
A self-contained display module with an internal alarm and power supply, connected to a remote power source via lanyard or power cord, ensuring continuous power to the item and activating an alarm upon tampering, with visual indicators and automatic switch activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple display modules are connected to a central alarm system and power supply, then centralized control is achieved, but it becomes difficult to rapidly determine which module caused the alarm and requires system deactivation for maintenance
Solution Approach 1:
The patent divides the centralized alarm system into independent modular units, where each display module contains its own alarm system and power supply. This segmentation allows each module to operate autonomously, making it easy to identify which specific module triggered an alarm without affecting other modules, and enables maintenance without deactivating the entire system.
Solution Approach 2:
The patent extracts the alarm system and power supply from the central control system and places them directly within each display module. This extraction eliminates the need for centralized control while maintaining security functionality, allowing rapid identification of alarmed modules and simplifying maintenance operations.
2Ease of operation
If products with internal batteries are displayed for extended periods, then customer inspection is enabled, but the batteries lose charge requiring constant recharging by store personnel
Solution Approach 1:
The patent implements continuous power supply to displayed products through the display module's power supply system. This ensures that products remain charged and operational throughout the display period without interruption, eliminating the need for periodic recharging by store personnel while maintaining customer accessibility.
Solution Approach 2:
The display module automatically provides power to the displayed product without requiring human intervention for recharging. The system self-manages the power supply, continuously maintaining the product's battery charge or providing direct power to keep the product operational during display.
3Reliability
If products are secured to display shelves with cables, then theft prevention is achieved, but customers cannot handle the items without store personnel assistance
Solution Approach 1:
The patent uses individual sensors attached to each product that are mechanically connected to the display module via flexible lanyards or power cords. This segmentation allows customers to freely move and handle products within the display area while the sensors remain attached to the display module, maintaining security without restricting customer interaction.
Solution Approach 2:
The patent employs flexible lanyards or power cords instead of rigid cables to connect the sensor to the display module. These flexible connections allow customers to move products freely while maintaining the security connection, enabling hands-on inspection without requiring store personnel assistance.

AI summary
A security system and display module therefore protects an item of merchandise mounted on the display module in a retail environment. The item of merchandise is electrically and mechanically connected to a sensor which is removably mounted on the display module by a first power cord. A second power cord connects the display module to the sensor and a third power cord connects the display module to a source of electricity for supplying electric power to the sensor through the display module and then to the displayed item for maintaining the charge on a battery of the displayed item. The display module contains an alarm unit having an audible alarm which is actuated if the integrity of either of the first or second power cords is compromised. A plunger switch and LED may be contained in the sensor and in a base of the display module and connected to the internal alarm to provide additional security for the protected item of merchandise. The alarm is powered from the source of electricity but is automatically switched to the battery upon interruption of this power source.
