Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spreading devices for fertilizers lack the ability to efficiently spread materials uniformly over fields due to fixed rotational speeds of spreading units, which limits their adaptability to varying field shapes and sizes.
Innovation Solution
The spreading device incorporates a power transmission mechanism with a speed-changing unit, allowing the rotational speed of each spreading unit to be adjusted independently, enabling different spreading distances and directions to achieve uniform coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed rotational speed is used for spreading units, then device structure is simple, but spreading uniformity and adaptability to varying field shapes deteriorate
Solution Approach 1:
The patent applies the dynamics principle by making the rotational speed of spreading units adjustable rather than fixed. The power transmission mechanism includes a speed changing unit that allows each spreading unit to operate at different rotational speeds, enabling adaptation to various field shapes and sizes while maintaining a relatively simple overall device structure.
Solution Approach 2:
The patent implements parameter changes by allowing the rotational speed parameter of each spreading unit to be varied independently. The power transmission mechanism enables adjustment of speed parameters to optimize spreading patterns for different field conditions, achieving versatility without significantly increasing device complexity.
2Manufacturing precision
If fixed rotational speed is used for spreading units, then device structure is simple, but spreading precision and uniformity deteriorate
Solution Approach 1:
The power transmission mechanism incorporates a speed changing unit that dynamically adjusts the rotational speed of each spreading unit. This enables precise control over material distribution patterns, ensuring uniform spreading across the field while the overall mechanism remains integrated and not overly complex.
Solution Approach 2:
The patent changes the speed parameter of the spreading units through the power transmission mechanism. By allowing independent speed adjustment, the system achieves precise control over spreading uniformity and precision without requiring multiple separate devices or overly complicated mechanisms.
3Productivity
If material is spread beyond boundaries, then spreading coverage is increased, but material loss and inefficiency increase
Solution Approach 1:
The patent uses parameter changes in the form of adjustable rotational speeds for each spreading unit. By optimizing the speed parameters, the spreading pattern can be precisely controlled to match field boundaries, ensuring complete coverage without excessive material spread beyond the intended area, thus improving efficiency and reducing loss.
Solution Approach 2:
The ability to independently adjust the rotational speed of each spreading unit creates a feedback mechanism where the operator can observe the spreading pattern and modify speeds to achieve optimal coverage. This allows real-time optimization to prevent material loss while maintaining high productivity.
