Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicide delivery systems are inefficient, inaccurate, and pose safety risks due to liquid sprays, pellet fragility, and environmental concerns, particularly in challenging terrains and arid conditions.
Innovation Solution
A semi-rigid, shell-less, water-soluble herbicide pellet system designed to maintain integrity during projection, releasing herbicide upon contact with moisture, and delivered using mechanisms like pellet guns or drones, with dosage calculated based on plant height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If liquid sprays are used for herbicide delivery, then application can be made, but drift and imprecise application occur affecting non-target vegetation
Solution Approach 1:
The patent extracts the herbicide from liquid form and incorporates it into solid pellets, eliminating the drift problem associated with liquid sprays. The pellets are delivered as discrete solid units that can be precisely targeted at unwanted vegetation without affecting non-target areas.
Solution Approach 2:
The patent changes the physical state of the herbicide from liquid to solid form. This parameter change enables precise delivery through pellet projection while eliminating the harmful drift effect of liquid sprays, achieving both improved precision and reduced environmental harm.
2Measurement precision
If dissolvable pellets are used, then delivery accuracy improves, but they lack sufficient weight and structural integrity for long-distance delivery
Solution Approach 1:
The patent uses composite materials to create pellets that combine sufficient weight for long-distance projection with water-soluble properties for effective herbicide release. The pellets are formulated with binding agents and herbicide compounds that provide both structural integrity during flight and dissolvability upon contact with moisture.
3Ease of operation
If paintball guns are used to deliver liquid-filled capsules, then delivery can be made, but capsules are fragile and may break during acceleration or flight
Solution Approach 1:
The patent removes the fragile capsule component from the delivery system and uses solid herbicide pellets instead. This eliminates the risk of capsule breakage during acceleration and flight while maintaining the ability to deliver herbicide effectively to target vegetation.
4Measurement precision
If workers physically approach each unwanted plant individually, then precise application can be made, but time consumption increases limiting coverage to 2-4 acres per day
Solution Approach 1:
The patent replaces the manual mechanical process of workers physically approaching each plant with an automated projection system. The pellet gun or drone delivers herbicide pellets remotely, enabling precise application while dramatically increasing the coverage area from 2-4 acres per day to much larger areas.
5Ease of operation
If traditional herbicide delivery methods are used in arid environments, then application can be made, but water scarcity limits activation of certain herbicide formulations
Solution Approach 1:
The patent changes the delivery method from liquid spray to solid pellet, which eliminates the water requirement for formulation activation. The water-soluble herbicide pellets are designed to dissolve upon contact with minimal moisture, enabling effective herbicide application in arid environments where water scarcity would otherwise limit formulation activation.

AI summary
An herbicide pellet system for efficient and accurate delivery of herbicides to plurality of unwanted plants is disclosed. Comprising the herbicide pellet system comprising an herbicide pellet and a delivery system for distributing the herbicide pellet to a portion of the plurality of unwanted plants. The herbicide pellet comprises a non-liquid degradable herbicide configured to release an herbicide near unwanted plant after a period or a rain event. The delivery system is configured to project the herbicide pellet as a projectile toward the unwanted plant among the plurality of unwanted plants. The herbicide pellet is of sufficient weight and shape to travel through the air in a predictable trajectory when projected by the delivery system. The herbicide pellet is configured to carry an herbicide dosage of an herbicide. The herbicide dosage is calculated to correlate with a plant height of the unwanted plant.
