Solution Overview
Problem
Existing diffuser spouts for agricultural fertilizer machines suffer from inefficiencies in material distribution due to rigid designs, leading to uneven spreading, material breakage, and susceptibility to wind, resulting in technical inefficiencies and economic losses.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a rigid flat metal plate or conical structure is used as a diffuser spout, then the material distribution width is increased, but the material breakage and uneven spreading occur
Solution Approach 1:
The patent introduces an adjustable height mechanism that allows the diffuser spout to be dynamically positioned at different heights above the ground. This dynamic adjustment capability enables optimization of the distribution pattern for different materials and soil conditions, resolving the contradiction between distribution width and uniformity by allowing the system to adapt rather than being fixed in a rigid configuration
Solution Approach 2:
The patent changes the geometric parameters of the diffuser spout by providing multiple selectable heights and angles. By varying these parameters, the system can optimize the balance between distribution width and material uniformity, preventing both excessive breakage and uneven spreading through parameter optimization
2Adaptability or versatility
If the diffuser spout height is fixed, then the structure is simple and stable, but the adaptability to different soil heights and materials is reduced
Solution Approach 1:
The patent implements a height adjustment mechanism that transforms the static diffuser spout into a dynamic system. This allows the same basic structure to adapt to various soil heights and material types without requiring multiple different spout designs, achieving versatility through controlled movement rather than structural complexity
Solution Approach 2:
The adjustable height mechanism enables a single diffuser spout design to serve multiple functions across different operating conditions. By making the height variable, the same structure can be optimized for different soil types, material densities, and distribution widths, achieving multi-functionality without proportionally increasing complexity
3Quantity of substance
If the diffuser spout is positioned closer to the ground, then the material spread is more concentrated, but the wind susceptibility and dispersion control are worsened
Solution Approach 1:
The height adjustment mechanism allows dynamic positioning of the diffuser spout to balance concentration and wind resistance. By enabling height variation, the system can be optimized for specific conditions - higher positions for wind-prone areas and lower positions for concentrated application needs - resolving the contradiction through adaptive positioning rather than fixed compromise

AI summary
A wide angle distributor of solid and/or liquid materials for pneumatic fertilizer and/or sowing machines that allows for a much more homogeneous spread of the fertilizer or granular material due to a novel spreading plate thereof that has a faceted surface that prevents the material accumulation and, in turn, provides a more homogeneous distribution and in a larger width than through the conventional spreading spouts of the prior art, and the wide angle distributor of the invention may vary its height in order to be adapted to the different materials and soil conditions in order to provide a correct and proper material spread on the surface.
