Wireless Merchandise Detector for Retail Inventory Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retail inventory management faces challenges in obtaining real-time data on stock levels and merchandising due to resistance against installing additional equipment, which is perceived as cluttering and requiring power supplies.
Innovation Solution
A wireless inventory monitoring system using merchandise detectors with sensors and transmitters that communicate as a wireless sensor network, minimizing visual impact and power dependence, allowing for comprehensive data collection on stock levels and merchandising without visible wiring or external power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional monitoring equipment is installed in retail outlets, then comprehensive real-time inventory data can be collected, but the retail environment becomes cluttered and visually impacted
Solution Approach 1:
The patent extracts the monitoring functionality from traditional visible equipment and relocates it to invisible wireless sensor nodes that can be concealed within or behind existing retail infrastructure, eliminating the visual clutter while preserving data collection capabilities
Solution Approach 2:
The patent introduces wireless communication technology as an intermediary between the physical retail environment and the data collection system, allowing monitoring equipment to operate invisibly through wireless signal transmission rather than requiring visible physical connections
2Reliability
If traditional monitoring equipment with power supplies is installed, then reliable data collection is achieved, but power infrastructure requirements increase complexity
Solution Approach 1:
The patent enables the sensor nodes to power themselves through wireless energy transmission techniques, allowing the monitoring equipment to be self-sufficient without requiring external power connections or infrastructure modifications in the retail environment
Solution Approach 2:
The patent replaces traditional mechanical/electrical power connection systems with wireless energy transmission methods, eliminating the need for physical power infrastructure while maintaining reliable operation of the monitoring equipment
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
Enables cost-effective, real-time inventory management with minimal visual impact, providing comprehensive data on stock levels and merchandising, reducing clutter and power dependency, and facilitating effective inventory management across retail outlets and supply chains.
Implementation Method 1
a plurality of proximity sensors fitted on the base layer in an elongate array, each said proximity sensor being configured to detect the presence or absence of an object on one side of the base layer
Data Source
AI summary
An inventory monitoring system (10) is provided, which includes a number of merchandise detectors (12) that each include a number of sensors that are configured to detect the presence or absence of products in a predetermined merchandise position, a position on a shelf in a retail space, and to emit a detect signal confirming such presence or absence. Each of the merchandise detectors (12) also includes a rear unit (28) with a transmitter that is connected to the sensor and that transmits the detect signal. The system (10) includes one or more gateway device (36,40) that receives the detect signals from the merchandise detectors (12) and compiles a merchandise data signal from the detect signals, and transmits it a computer (42) to be used in monitoring and managing inventory.
