Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high concentrations of active ingredients are used in agrochemical formulations, then effectiveness against phytopathogenic fungi and undesirable plant growth is improved, but cost increases and compatibility issues arise
Solution Approach 1:
The patent introduces hydroxyalkyl polyoxylene glycol ethers as intermediary substances (adjuvants) that mediate between the active ingredient and the target organism. These compounds enhance the biological activity and effectiveness of the active ingredient, allowing lower concentrations to achieve the same or better efficacy. The adjuvants act as carriers or penetration enhancers, facilitating better delivery and action of the active ingredient.
Solution Approach 2:
The patent changes the formulation parameters by incorporating specific adjuvants (hydroxyalkyl polyoxylene glycol ethers) that modify the physical and chemical properties of the formulation. This changes the delivery mechanism and bioavailability of the active ingredient, enabling effective pest control at reduced concentrations.
2Reliability
If conventional adjuvants are used to improve pesticide activity, then effectiveness is enhanced, but compatibility issues and limited effectiveness under adverse conditions persist
Solution Approach 1:
The patent creates composite formulations by combining pesticides with hydroxyalkyl polyoxylene glycol ethers. This composite approach integrates multiple functional components that work synergistically: the active ingredient provides pesticidal activity while the adjuvant provides enhanced compatibility, stability, and performance under adverse environmental conditions.
Solution Approach 2:
The hydroxyalkyl polyoxylene glycol ethers serve multiple functions simultaneously: they act as penetration enhancers, compatibility agents, stability improvers, and effectiveness boosters. This multi-functionality allows a single adjuvant component to address multiple formulation challenges and improve performance across diverse application conditions.
3Quantity of substance
If reduced amounts of active ingredient are used, then cost is minimized and legislation requirements are met, but effectiveness may be compromised
Solution Approach 1:
The adjuvant acts as an intermediary that amplifies the effect of reduced active ingredient concentrations. By incorporating hydroxyalkyl polyoxylene glycol ethers, the formulation compensates for lower active ingredient levels through enhanced penetration, retention, and biological activity, maintaining effectiveness while reducing quantity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hydroxyalkyl polyoxylene glycol ether enhances the activity and uptake of pesticides, allowing for reduced active ingredient usage, improved compatibility, and increased effectiveness against phytopathogenic fungi and undesirable plant growth, as demonstrated by field trials and greenhouse studies.
Implementation Method 1
Frequently, they take the form of surface-active or salt-like compounds. As regards the uptake of the active ingredient into the leaf, surface-active substances may act as modifiers and adjuvants.
Implementation Method 2
In general, it is assumed that suitable surface-active substances are capable of increasing the effective contact area of fluids on leaves by providing better wetting.
Implementation Method 3
Moreover, certain surface-active substances act as plasticizer, i.e. are capable of changing the epicuticular waxy layer from a crystalline to an amorphous state, which facilitates the sorption of the active ingredient.
Implementation Method 4
Furthermore, some surface-active substances are also capable of improving the solubility of active ingredients in formulations, thereby avoiding, or at least delaying, crystal formation.
Implementation Method 5
Finally, in certain cases they can also influence the absorption of active ingredients by retaining moisture.
