Solution Overview
Problem
The existing method of fertilizing plants with 5-aminolevulinic acid in a solution is cumbersome and requires frequent applications to achieve a growth-promoting effect, which lasts only about two weeks.
Innovation Solution
Converting 5-aminolevulinic acid into a solid fertilizer form, combined with a nitrogen-rich fertilizer, and coating it with petroleum wax to create a sustained-release formulation that can be easily applied, reducing the frequency of applications while maintaining a remarkable plant growth-promoting effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 5-aminolevulinic acid is applied in liquid solution form, then the application method is simple, but the duration of growth promoting effect is short (about 2 weeks) and frequent administrations are needed
Solution Approach 1:
The patent changes the physical state of 5-aminolevulinic acid from liquid solution to solid granular form by incorporating it into fertilizer granules. This parameter change enables the substance to be applied as a solid that releases gradually, extending the duration of effect from 2 weeks to covering the entire growing season, while maintaining ease of application through standard fertilizer spreading equipment
Solution Approach 2:
The solid fertilizer formulation provides continuous release of 5-aminolevulinic acid throughout the growing season, replacing the discontinuous repeated applications required by liquid solutions. The sustained-release mechanism ensures the plant growth-promoting effect continues without interruption, eliminating the need for frequent re-application
2Ease of operation
If 5-aminolevulinic acid is applied in liquid solution form, then the initial application is easy, but the number of applications must be large and the total effort is great
Solution Approach 1:
By transforming 5-aminolevulinic acid into solid granular fertilizer form, the patent enables single-season application instead of multiple liquid applications. The solid formulation maintains simplicity of application through conventional fertilizer spreaders while reducing the total number of application events from multiple times per season to once per season, significantly reducing time and labor investment
3Duration of action of moving object
If 5-aminolevulinic acid is converted to solid fertilizer form, then the duration of effect is extended and applications are reduced, but the formulation complexity increases
Solution Approach 1:
The patent creates a composite fertilizer material by incorporating 5-aminolevulinic acid into fertilizer granules that contain multiple nutrients (nitrogen, phosphorus, potassium, and other elements). This composite approach extends the duration of effect through sustained release while managing formulation complexity by integrating the active substance into a multi-component fertilizer system that can be produced using existing granulation and coating technologies
