Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current applicators for killing weeds and pests like slugs or snails are often bulky and difficult to transport over uneven terrain, and require extensive application time due to inefficiencies in delivering herbicides.
Innovation Solution
A portable applicator that uses a pressurized and heated stream of liquid, potentially mixed with organic herbicides, to effectively target and kill plants and pests by penetrating cellular structures, allowing for directable and efficient delivery to roots, leaves, and confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional applicators use heavy backpacks or rollers to transport herbicides, then herbicide delivery capacity is improved, but portability and ease of transport over uneven ground deteriorates
Solution Approach 1:
The system divides the herbicide delivery function into two separate components: a lightweight handheld applicator for precise application and a separate herbicide source (backpack or reservoir) that can be positioned optimally. This segmentation allows the application device itself to remain portable while maintaining adequate herbicide supply capacity.
Solution Approach 2:
A flexible hose or tube acts as an intermediary connection between the herbicide source and the handheld applicator, allowing the herbicide to be transported over uneven terrain without requiring the applicator itself to be heavy or bulky. The flexible conduit adapts to ground contours while maintaining fluid delivery.
2Productivity
If traditional applicators deliver herbicides without pressurization or heating, then device complexity is reduced, but application time and efficiency deteriorates
Solution Approach 1:
The system changes the physical parameters of the herbicide delivery by introducing pressurization (increasing flow rate and penetration capability) and heating (improving herbicide effectiveness and evaporation rate). These parameter changes significantly enhance application efficiency and reduce treatment time.
Solution Approach 2:
The system replaces passive gravity-based or pump-based delivery with a more sophisticated pressurized thermal delivery system. The combination of mechanical pressurization and thermal processing creates a more effective application mechanism that overcomes the limitations of simple mechanical pumping.
3Reliability
If traditional applicators use unpressurized liquid delivery, then device complexity is reduced, but herbicide penetration into plant cellular structures deteriorates
Solution Approach 1:
By dramatically increasing the pressure parameter of the liquid delivery system, the patent achieves sufficient force to penetrate plant cellular structures and deliver herbicides effectively to target organisms. The high pressure overcomes the natural resistance of plant tissues and ensures reliable herbicide uptake.
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
The pressurized and heated liquid stream enhances lethality, reduces herbicide usage, and allows for precise targeting, making the applicator more effective and efficient in killing plants and pests with less material, while being portable and easy to use.
Implementation Method 1
The applicator may include a heating element configured to heat the liquid
Implementation Method 2
The applicator may include a pump configured to pressurize the liquid

AI summary
Embodiments provide an applicator configured to pressurize and heat a mixture of water and herbicide, and expel the heated and pressurized water/herbicide mixture from the applicator. In some embodiments, the herbicide may be an organic herbicide such as organic acids, simple sugars, surfactants, or ammonia. The applicator may include an inline heating element coupled with a spray tip of the applicator such that the inline heating element may receive a water/herbicide mixture from a water line of the applicator, heat the water/herbicide mixture, and then supply the water/herbicide mixture to the spray tip.
