Hinged Weed Applicator Sealing Fluid Treatments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for applying herbicides to weeds in close proximity to desired plants are inefficient, often damaging the desired plants, requiring frequent treatments, and exposing the environment to chemicals, which can lead to contamination and unintended harm.
Innovation Solution
A plant surface contact material applicator with two protective shells joined by a hinge and clasp, creating a sealed containment environment to apply fluid treatments directly to targeted plants while isolating the treatment from the external environment, preventing leakage and exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If broadcast spraying methods are used to apply herbicides, then labor efficiency is improved and large areas can be treated quickly, but the herbicides can drift and contaminate adjacent desired plants causing damage
Solution Approach 1:
The applicator divides the treatment area by using a physical barrier (the applicator device itself) to segment and isolate the herbicide application zone from surrounding areas, preventing drift and contamination while maintaining efficient treatment
Solution Approach 2:
The applicator uses a flexible barrier shell that can conform to plant shapes and seal around targeted vegetation, creating an isolated containment environment that prevents herbicide escape while allowing efficient application
2Reliability
If mechanical weed control methods are used, then weed removal is achieved, but the soil is disrupted leading to erosion and exposure of additional weed seeds
Solution Approach 1:
The invention replaces disruptive mechanical soil disturbance methods with a chemical treatment approach that applies herbicides directly to weed foliage, achieving weed removal without soil erosion or exposure of buried weed seeds
3Productivity
If selective herbicides are applied using broadcast methods, then labor is saved and treatment is quick, but the herbicides are exposed to environmental disturbances and can be absorbed by pets and children
Solution Approach 1:
The flexible barrier shell creates a sealed containment environment that isolates the herbicide from the external environment, preventing exposure to pets, children, and environmental disturbances while maintaining quick treatment application
Solution Approach 2:
The applicator segments the treatment area by sealing around individual plants or small groups, isolating the herbicide within defined boundaries to prevent environmental exposure and contamination

AI summary
An apparatus and method deliver fluid treatments to a targeted plant. The apparatus comprises a two-piece protective shell joined on one side by a spring-hinge. When the two piece outer protective shell is open, a fluid treatment is applied to a liquid retaining material within the protective shell. A portion of a targeted plant is placed within the open outer protective shell. The two piece outer protective shell is then closed, creating a sealed containment environment that is immediately protected from environmental disturbance, prevents distribution of fluid treatment to non-treated plant materials, and will retain, store, and prevent leakage of the fluid treatment. The closed outer protective shell also clasps the plant portion, forcing contact of the target plant portion with fluid treatment residing on and within the liquid retaining material. The apparatus remains attached to the targeted plant while the fluid treatment is absorbed through systemic plant processes.
