Innovation Solution
The development of solid herbicidal concentrate compositions comprising glyphosate salt components with specific molar ratios of monovalent salt-forming cations and monocarboxylic acid salts, along with auxin herbicide and co-herbicide salt components, which are prepared through processes involving over-neutralization and drying to form stable granules, thereby incorporating additives that reduce volatility and enhance handling characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If solid herbicidal concentrate compositions are prepared from liquid and solid reactants, then the compositions provide superior handling characteristics and reduced transportation weight, but the production cost and compounding complexity increase
Solution Approach 1:
The patent changes the physical state parameter of the herbicidal composition from liquid to solid form. This fundamental parameter change enables superior handling characteristics and reduced transportation weight while maintaining effectiveness through controlled conversion processes that manage the complexity of the transformation
2Productivity
If multiple herbicide active ingredients are combined in a single solid composition, then mixing errors are reduced and weed control spectrum is broadened, but the compatibility with additives and sensitivity to process conditions increase
Solution Approach 1:
The patent performs preliminary action by pre-combining multiple herbicide active ingredients in a solid composition before field application. This advance combination ensures proper mixing ratios are achieved and allows for preliminary testing of additive compatibility under controlled process conditions, reducing risks during actual use
Solution Approach 2:
The patent creates a composite material by combining multiple herbicide active ingredients with compatible additives in a solid matrix. This composite approach ensures stable interactions between components while maintaining the effectiveness of each ingredient and reducing sensitivity to process variations
3Ease of operation
If additives such as surfactants are added to enhance formulation properties, then efficacy and handling characteristics are improved, but the sensitivity to elevated temperatures during processing increases
Solution Approach 1:
The patent changes the temperature parameter control during processing to accommodate heat-sensitive additives. By adjusting processing temperatures to lower ranges and controlling thermal exposure time, the patent maintains additive stability while still achieving effective solid composition formation
