Solution Overview

Problem

Current RFID systems face challenges in tracking and tracing marijuana plants and products due to adverse RF propagation characteristics, particularly with materials like soil and water, and require effective solutions for regulatory compliance and efficient tracking throughout the plant's life cycle.

Innovation Solution

The implementation of an RFID tag system that includes a strap and waterproof, chemically resistant RFID labels, allowing for attachment to plants or their pots, and utilizing RFID buy cards for transaction control and tracking, enabling serialization and central serialization for regulatory compliance and tax collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If RFID tags are used to track marijuana plants through soil and water environments, then tracking capability is improved, but RF signal propagation is degraded by adverse characteristics of soil and water materials

Engineering Contradiction:
Improvetracking capabilityVSAvoidRF signal propagation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the intermediary principle by introducing a waterproof chemically resistant label as a mediator between the RFID tag and the adverse soil/water environment. This label protects the RFID tag from direct exposure to harmful materials while maintaining tracking functionality, allowing the system to operate reliably in challenging agricultural environments.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements parameter changes by modifying the physical and chemical properties of the label material to be waterproof and chemically resistant. This changes the environmental parameters (water exposure, chemical exposure) that the RFID tag experiences, thereby improving signal propagation and tag reliability in soil and water environments.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If RFID tags are attached to plants through their life cycle from seed to sale, then tracking completeness is improved, but device complexity increases due to need for durable attachment mechanisms

Engineering Contradiction:
Improvetracking completenessVSAvoidattachment mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a waterproof chemically resistant label that serves multiple functions: it protects the RFID tag, provides durable attachment to plants through various growth stages, and maintains functionality across different environmental conditions. This multi-functional design reduces the need for multiple separate components.

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

Solution Approach 2:

The patent uses composite materials by combining RFID tag technology with waterproof chemically resistant label material. This composite structure integrates the electronic tracking component with a protective and adhesive material system that can withstand plant handling, washing, and environmental exposure throughout the plant's life cycle.

Inventive Principle:
Principle #40Composite materials

3Reliability

If centralized RFID tag provisioning is implemented for regulatory compliance, then regulatory control is improved, but system complexity increases

Engineering Contradiction:
Improveregulatory complianceVSAvoidsystem architecture
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by implementing centralized RFID tag provisioning that pre-serializes and pre-configures tags before they reach end users. This advance preparation ensures regulatory compliance is built into the system from the outset, and the ordering subsystem automatically manages tag distribution and tracking without requiring complex real-time regulatory decision-making at each usage point.

Inventive Principle:
Principle #10Preliminary action

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

This solution ensures reliable tracking of marijuana plants from seed to sale, enhances regulatory compliance, and facilitates efficient inventory management and tax collection, while maintaining security and consistency in RFID tag production.

Implementation Method 1

RFID (Radio Frequency Identification) technology is an identification technology that is commonly used to identify, track, and/or trace goods... Radio frequency identification (RFID) technology enables automatic identification of unique items by using radio frequency (RF) signals.

Methodology Applied
Scientific EffectRadio frequency identification: Electromagnetic Induction

Implementation Method 2

Passive RFID tags do not contain an on-tag power source. Passive tags harvest all of the tag's operational energy from the RFID reader's communication signal and use this harvested power to send back a signal with the information on the tag.

Methodology Applied
Scientific EffectEnergy harvesting: Electromagnetic Induction
