Solution Overview

Problem

Current systems for inventory tracking in retail environments lack efficient methods to determine and track inventory using integrated lighting solutions, which can be affected by heat generation and require manual intervention for tag reading, limiting accuracy and automation.

Innovation Solution

A hybrid lighting and inventory system that incorporates networked light providers with integrated RFID tag readers and controllers, allowing for wireless communication and automated tag reading, minimizing heat impact on light elements and enabling real-time inventory tracking and alert systems through light and auditory alarms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If RFID tag reading operations are performed frequently to improve inventory tracking accuracy, then measurement precision is improved, but heat generated by the internal circuit increases and reduces light element life

Engineering Contradiction:
Improveinventory tracking accuracyVSAvoidheat generated by internal circuit
Core Design Contradiction:
Measurement precisionVSTemperature

Solution Approach 1:

The system performs tag reading operations periodically rather than continuously, scheduling readings during off-peak hours or when lighting is not needed. This reduces cumulative heat exposure to the light element while still achieving accurate inventory tracking through repeated measurements over time.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system proactively manages heat by implementing cooling intervals between tag reading operations and by monitoring temperature levels to prevent excessive heat accumulation. This preliminary anti-action prevents heat-related degradation before it occurs.

Inventive Principle:
Principle #9Preliminary anti-action

2Device complexity

If the light provider is used for both lighting and inventory tracking functions, then device complexity is reduced, but the reliability of each individual function decreases due to shared components

Engineering Contradiction:
Improvesystem integrationVSAvoidfunction performance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The light provider is designed with multi-functionality, incorporating both lighting elements and RFID tag reading capabilities within a single device. The internal circuit can switch between providing illumination and performing inventory tracking, eliminating the need for separate dedicated devices while maintaining operational reliability through proper thermal management.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If continuous monitoring is implemented to improve inventory tracking speed, then productivity is improved, but energy consumption increases

Engineering Contradiction:
Improveinventory tracking speedVSAvoidenergy consumption by light provider
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous monitoring, the system implements periodic tag reading operations at strategically timed intervals. This maintains productivity by ensuring inventory data is updated frequently enough for operational needs while dramatically reducing energy consumption compared to continuous operation.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system intelligently schedules tag reading operations based on its own operational state, performing readings when energy is available and cooling is adequate, thereby self-regulating to balance productivity with energy conservation.

Inventive Principle:
Principle #25Self-service

AI summary

Systems and methods for determining an inventory. The methods comprise: performing operations by an internal circuit of a light provider to control operations of a light element to produce visible light, where the light provider is coupled to a light fixture installed an a physical structure of a facility; and performing operations by the internal circuit to connect with a network, receive a tag identifier associated with an alert event from at least one external device via the network, read tags, and control the light element to modify at least one characteristic of the visible light produced thereby when information read from one of the tags includes the tag identifier.
