Solution Overview
Problem
Current methods for determining the necessary amount of application material for agricultural areas are imprecise, leading to inefficiencies and residual materials in spreading machines, which are time-consuming and costly to empty.
Innovation Solution
A method that uses a data processing device to calculate the required application material by distinguishing between interior and border areas of the agricultural field, accounting for varying application rates and restrictions, ensuring precise filling and zero-residual material in the machine post-process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a uniform amount of spreading material is applied across the entire agricultural area, then the interior areas receive adequate material, but border areas receive excessive material that cannot be evenly distributed
Solution Approach 1:
The patent applies different spreading rates to different zones within the agricultural area. Interior areas receive a first spreading rate while border areas receive a second, lower spreading rate. This local differentiation resolves the contradiction by ensuring uniform distribution where needed while reducing excess application at boundaries where even distribution is physically impossible.
2Area of stationary object
If the spreading machine is filled with a large amount of material to cover the entire area, then complete coverage is achieved, but residual material remains in the machine after completion
Solution Approach 1:
The system performs preliminary calculation of the exact material quantity needed by integrating the area of interior zones multiplied by the first spreading rate and the area of border zones multiplied by the second spreading rate. This preliminary determination allows precise filling of the spreading machine, ensuring complete area coverage while minimizing residual material through accurate quantity planning.
3Quantity of substance
If the spreading machine is filled with a small amount of material to avoid residuals, then refilling frequency increases, but coverage completeness is compromised
Solution Approach 1:
The system incorporates feedback through precise calculation of total material requirements based on mapped interior and border areas, their respective spreading rates, and the spreading machine's capacity. This feedback loop enables optimal filling that maximizes operational efficiency by minimizing refilling frequency while maintaining complete coverage and avoiding residuals.
4Measurement precision
If border spreading is excluded to avoid material loss, then material precision improves, but border areas remain uncovered
Solution Approach 1:
The patent changes the spreading rate parameter for border areas compared to interior areas. By applying a reduced second spreading rate to border zones rather than excluding them entirely, the system maintains coverage of all areas while improving material application accuracy through localized parameter adjustment that accounts for the physical constraints of border spreading.

AI summary
The invention relates to a method for determining the quantity of application material required for an application process on an agricultural area, comprising the steps of: identifying the boundaries of an agricultural area and determining the necessary quantity of application material for an application process on the agricultural area, wherein, when determining the necessary quantity of application material for the application process on the agricultural area, the boundary application within areas near the boundaries of the agricultural area, which deviates from the substantially uniform material application within interior areas far from the boundaries of the agricultural area, is taken into account.
