Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex conversion processes are used to switch between drilling and on-demand delivery systems, then delivery mode transformation is achievable, but transformation time increases and operational efficiency decreases
Solution Approach 1:
The delivery system is divided into modular components: a removable dosing device module that can be quickly exchanged between drilling and on-demand delivery configurations. The seed box, air box, and dosing mechanisms are segmented into interchangeable units that simplify the conversion process and reduce transformation time.
Solution Approach 2:
The system incorporates adjustable and reconfigurable components that allow dynamic switching between delivery modes. The air box and dosing device are designed with movable parts and adjustable settings that enable rapid transformation without requiring complete disassembly or complex tool-based operations.
2Adaptability or versatility
If specialized tools and personnel are required for conversion, then precise transformation is achieved, but operational complexity and cost increase
Solution Approach 1:
The system is designed for operator self-service conversion. The modular dosing device and air box components feature tool-free attachment and detachment mechanisms that allow field operators to perform mode transformations without specialized tools or technical expertise. Quick-connect interfaces and snap-fit mechanisms enable simple configuration changes.
Solution Approach 2:
The air box and dosing device are designed as universal components that can function in multiple delivery modes. The same basic structure supports both drilling and on-demand delivery operations, eliminating the need for mode-specific equipment and simplifying the conversion process to a matter of component reconfiguration.
3Adaptability or versatility
If the seed drill is removed from the field for conversion, then proper transformation is ensured, but operational continuity is interrupted
Solution Approach 1:
The system incorporates dynamically reconfigurable components that can be adjusted in the field without removing the seed drill from operation. The air box and dosing device feature quick-change mechanisms that allow mode transformation while the machine remains positioned in the field, maintaining operational continuity.
Solution Approach 2:
The modular components are pre-configured for both drilling and on-demand delivery modes during manufacturing. This preliminary preparation allows field operators to simply exchange pre-built modules rather than performing complex conversions, enabling rapid mode switching without interrupting field operations.
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
Enables quick and simple transformation of seed drills between delivery modes, reducing downtime and optimizing hopper autonomy for various grain types.
Implementation Method 1
transporting granulated solid materials via an air current, from a container or hopper to the means of implantation of said materials
Implementation Method 2
The air box is basically formed by a hollow body in the form of a tunnel, with an air inlet at its rear end, air current that at its opposite end proceeds to drive the granulated material

AI summary
Agricultural implement assembly, for the rapid transformation of a seed drill with a drilling or dragging dosing device, volumetric supplier to an on-demand supplier and vice versa, including at least one hopper containing a granular input, such as grains, seeds or granules of agrochemicals, and a delivery device arranged under the hopper. This device has a structure consisting of two physically delimited areas. A seed box is formed by side walls that delimit its width, a bottom wall, a rear wall with the air inlet from the fan, and a front partition that has at least the passage of the seed to the area where the dragging rotor is eventually located for the case of drilling work, or to the area where the containment slope is located for the case of on-demand supply.
