Solution Overview
Problem
The existing spreader devices with two rotors struggle to achieve an optimal spreading pattern due to restricted spreading patterns, which are not adaptable to the shape of the agricultural field, the position of the spreader device, and the planting position of crops.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two rotors are used for spreading, then the device structure is simple, but the spreading pattern is restricted and cannot adapt to different field shapes and crop positions
Solution Approach 1:
The spreading device is divided into multiple independent rotor units (first rotor, second rotor, third rotor) that can operate semi-independently. Each rotor can be controlled to rotate at different speeds and directions, allowing the system to create complex spreading patterns by coordinating multiple simpler elements, thus resolving the contradiction between structural simplicity and pattern adaptability.
Solution Approach 2:
The patent implements dynamic control of rotor rotation speeds through a driving-force transmission mechanism with variable gear ratios. The rotation speed of each rotor can be adjusted in real-time based on operational requirements, enabling the system to adapt spreading patterns dynamically to different field shapes and crop positions while maintaining a relatively simple mechanical structure.
2Adaptability or versatility
If multiple rotors with independent control are added to achieve optimal spreading patterns, then spreading pattern adaptability improves, but device complexity increases
Solution Approach 1:
Multiple rotor units are merged into a single integrated spreading device with a shared container portion and a unified driving-force transmission mechanism. This consolidation allows the system to achieve complex spreading capabilities through coordinated operation of multiple rotors while avoiding the complexity of multiple separate devices, thus improving adaptability without proportionally increasing overall device complexity.
Solution Approach 2:
The driving-force transmission mechanism is designed with universal applicability to control multiple rotors through a single system. The mechanism can distribute driving force to different rotors with different gear ratios, enabling one transmission system to perform multiple functions of controlling various rotors at different speeds, thereby reducing the need for separate control systems for each rotor and limiting the increase in device complexity.
3Manufacturing precision
If gear ratios are adjusted to control rotor speeds for optimal spreading, then spreading precision improves, but the driving-force transmission mechanism becomes more complex
Solution Approach 1:
The patent employs variable gear ratios in the driving-force transmission mechanism to precisely control the rotation speeds of different rotors. By changing the gear ratio parameters, the system can achieve optimal spreading patterns with precise control over material distribution, while the modular design of the transmission mechanism keeps the complexity manageable through standardized mechanical components.
