Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural sprayers face challenges in achieving even distribution of agricultural products due to irregular field shapes and sprayer configurations, leading to unpredictable application variations and waste of products, with existing systems experiencing lag times and lack of individualized control in mixing and dispensing injection products.
Innovation Solution
A localized product injection system that provides a pressurized source of injection products directly at the product dispensers, such as boom sections or nozzle assemblies, allowing for instantaneous mixing and application with individualized control, eliminating lag time and ensuring precise concentration adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If injection products are mixed and delivered through a header and boom tubes to sections and nozzles, then the agricultural products can be distributed across multiple rows, but lag time and latency occur between injection and application
Solution Approach 1:
The system divides the injection system into multiple independent localized injection interfaces, each serving a specific boom section or nozzle assembly. This segmentation eliminates the need for long header tubes and intermediate mixing chambers, allowing direct injection at each dispensing location and thereby eliminating lag time while maintaining distribution coverage across multiple rows.
Solution Approach 2:
The system transitions from a centralized linear injection approach (through header tubes) to a distributed spatial arrangement where multiple independent injection interfaces are positioned at different locations along the boom. This dimensional redistribution allows simultaneous injection at multiple points, eliminating the sequential lag inherent in centralized systems.
2Device complexity
If a centralized mixing system is used with header tubes and boom tubes, then the system structure is simplified, but individualized control of injection concentration at each dispenser is lost
Solution Approach 1:
The centralized mixing system is segmented into multiple independent localized injection interfaces, each with its own control capability. This allows individualized adjustment of injection concentration at each boom section or nozzle assembly while maintaining a relatively simple overall system structure through modular design.
Solution Approach 2:
The system incorporates dynamically controllable injection interfaces that can independently adjust injection rates and concentrations in real-time. This dynamic control capability enables individualized adaptation at each dispenser location while the modular architecture keeps the overall system structure manageable and not excessively complex.
3Ease of operation
If injection products are delivered through long header tubes and boom tubes, then centralized delivery is achieved, but unpredictable variation in application occurs due to irregular field shapes and sprayer configurations
Solution Approach 1:
The long centralized delivery system is segmented into multiple short localized injection interfaces positioned at different locations along the boom. Each interface independently delivers injection products to its specific target area, eliminating the unpredictable variations that occur in centralized long-tube delivery systems when encountering irregular field shapes and sprayer configurations.
Solution Approach 2:
Each localized injection interface is optimized for its specific location and function, allowing tailored injection parameters and configurations for different boom sections or nozzle assemblies. This local optimization ensures consistent and uniform application across varying field conditions and sprayer configurations, unlike the uniform centralized approach that cannot adapt to local variations.
4Quantity of substance
If inline mixing is performed upstream from or within the header, then mixing occurs before distribution, but waste of agricultural products occurs due to unpredictable application variation
Solution Approach 1:
The upstream centralized mixing process is segmented into multiple localized injection interfaces positioned at or near the dispensing points. This eliminates the need for premature mixing in long header tubes, allowing injection products to be delivered directly to where they are needed, thereby improving mixing efficiency at the point of application and preventing product waste from unpredictable distribution patterns.
Solution Approach 2:
Instead of performing mixing action upstream in the header tubes, the system performs preliminary injection directly at the localized interfaces near the dispensing points. This timing optimization ensures that mixing and application occur in close proximity and time, preventing product waste that would result from premature mixing followed by unpredictable distribution through long tube systems.

Function Achieved in This Case
The system enables instantaneous and precise application of agricultural products with minimal lag time and variation, adapting to field conditions for optimal distribution and reducing waste by providing immediate and controlled injection at each dispenser.
Implementation Method 1
maintains a pressurized source of the injection product immediately adjacent to each of the product dispensers and accordingly ready for instantaneous injection to the flow of the carrier substance immediately prior to dispensing
