Direct Injection Fluid Reservoir for Precision Pesticide Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current farming technologies, particularly in pesticide application, face challenges in optimizing crop yield while ensuring operator safety and minimizing environmental impact, as conventional crop sprayers often require mixing tanks and lack efficient packaging solutions for reusable and recyclable containers.
Innovation Solution
A fluid delivery system incorporating a product reservoir with a flexible bag and carton, designed for direct injection systems, where the pesticide is mixed with water inline, eliminating the need for mixing tanks and allowing for closed transfer systems, thereby enhancing precision farming and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional crop sprayers use mixing tanks for pesticide application, then pesticide can be applied to crops, but operator exposure to pesticides increases and mixing complexity is required
Solution Approach 1:
The patent removes the mixing tank component from the crop sprayer system entirely. Instead of mixing pesticide and water in a tank before application, the system uses a direct injection approach where concentrated pesticide is injected directly into the water stream at the nozzle, eliminating the need for a separate mixing tank and reducing operator exposure to mixed pesticide solutions
Solution Approach 2:
The patent introduces water as an intermediary medium. Concentrated pesticide is injected into a water stream, and the two mix in the flowing water rather than in a stationary mixing tank. This allows mixing to occur in a controlled manner during flow, reducing static exposure risks while maintaining mixing functionality
2Object-affected harmful factors
If reusable pesticide containers are used, then environmental impact is reduced, but cleaning and sanitization between uses becomes more complex
Solution Approach 1:
The patent describes a system where pesticide containers can be disposed of after use rather than cleaned and reused. The container design includes features that facilitate complete drainage and disposal, eliminating the need for complex cleaning and sanitization processes while reducing environmental impact through proper disposal programs
Solution Approach 2:
The patent implements a system where used pesticide containers are discarded and recovered through specialized recycling programs. The container design facilitates easy emptying and identification of contents, enabling efficient recovery and proper disposal or recycling processes that are simpler than cleaning and sanitizing requirements
3Object-affected harmful factors
If direct injection systems are used for pesticide application, then operator safety is improved, but precision in pesticide delivery becomes more challenging
Solution Approach 1:
The patent incorporates feedback mechanisms in the direct injection system, including flow sensors and pressure regulators that monitor and adjust the injection rate of pesticide into the water stream. This feedback control ensures precise delivery of the correct amount of pesticide while maintaining operator safety through automated control
Solution Approach 2:
The patent replaces manual mixing and delivery controls with automated electronic control systems. The direct injection system uses electronically controlled pumps and valves to regulate pesticide flow, replacing mechanical mixing processes with electronically monitored injection, thereby maintaining precision while improving operator safety

AI summary
A product reservoir is provided that includes a flexible bag and a carton to receive and retain the flexible bag. The bag may contain liquid chemical substances that are dispensed from the bag through a bag spout. The product reservoir may serve as a component to a fluid delivery system, such as a direct injection system employed by agricultural seed planting machines. When the bag is connected to the direct injection system, the liquid substance is placed in fluid communication with a delivery device whereby the substance can be dispensed to a selected area for treatment. The liquid substance may be mixed in-line with water received from a water reservoir prior to being dispensed by the delivery device. The planting machine may be equipped with a plurality of product reservoirs. A method of applying a liquid pesticide to a selected area is also provided.
