Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seed treatment methods result in stickiness and tackiness on seed surfaces, leading to flow issues in manufacturing and planting equipment, non-uniform coverage, and poor visual appearance, which can cause planting errors and lower crop yields.
Innovation Solution
A method involving a liquid seed treatment composition with a flowability agent followed by a dry powder effect pigment application, enhancing seed flowability and visual appeal by creating a uniform coating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a liquid seed treatment composition is applied as a coating, then agrochemical coverage is achieved, but stickiness and tackiness are imparted to the seed surface causing flow problems
Solution Approach 1:
The coating is divided into two distinct layers: a liquid seed treatment composition layer providing agrochemical coverage, and a dry powder outer layer providing flowability. This segmentation allows each layer to independently fulfill its function without interfering with the other, resolving the contradiction between coverage and flowability
Solution Approach 2:
The seed coating becomes a composite structure combining liquid treatment composition (providing agrochemical functionality) with dry powder material (providing flowability). This composite approach allows the system to simultaneously achieve both agrochemical coverage and improved seed flow through equipment
2Quantity of substance
If conventional seed treatment formulations are used, then agrochemical application is achieved, but non-uniform coverage and poor visual appearance result
Solution Approach 1:
The liquid seed treatment composition is applied first to establish uniform agrochemical coverage on the seed surface. This preliminary action ensures that the agrochemical layer is evenly distributed before the dry powder is added, preventing the non-uniform coverage and blotchiness associated with conventional single-step formulations
3Reliability
If seed treatments are applied to improve agrochemical coverage, then protection is provided, but planting errors and lower crop yields occur due to flow issues
Solution Approach 1:
By segmenting the coating into functional layers (liquid treatment layer for protection, dry powder layer for flowability), the invention maintains reliable agrochemical protection while eliminating flow problems that cause planting errors and yield reduction
Solution Approach 2:
The invention changes the physical parameters of the coating by adding a dry powder component that modifies surface characteristics. This parameter change improves flowability and reduces planting errors while maintaining the protective function of the agrochemical layer, thereby preserving crop yield
