Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If conventional agrochemical compositions are used, then they can provide agricultural activity, but they exhibit poor chemical and physical stability under varying storage and use conditions leading to phase separation

Engineering Contradiction:

Improvechemical and physical stabilityVSAvoidphase separation

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The patent changes the chemical parameters of the formulation by using laminarin as the active ingredient at specific concentrations (0.1-10% w/v) and combining it with specific polyols (glycerol, sorbitol, mannitol) at optimized ratios. This parameter optimization resolves the contradiction by achieving both agricultural efficacy and enhanced stability without phase separation, even under extreme storage conditions.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite formulation system combining laminarin (a polysaccharide) with polyols as co-solvents. This composite approach leverages the synergistic interaction between the biostimulant properties of laminarin and the stabilizing properties of polyols, resulting in a formulation that maintains both effectiveness and stability without phase separation.

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If liquid products are stored in bulk facilities, then they can be handled efficiently, but they are subject to high shear forces at high and low temperatures causing instability

Engineering Contradiction:

Improvebulk handlingVSAvoidtemperature stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent incorporates polyols (glycerol, sorbitol, or mannitol) as protective agents that cushion the laminarin molecules against the damaging effects of high shear forces and temperature extremes. This beforehand protection ensures the formulation remains stable during bulk storage and handling operations, preventing degradation that would otherwise occur under these stressful conditions.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Productivity

If adjuvants are added to enhance biological activity, then agricultural performance improves, but the number of approved auxiliary chemicals is decreasing due to stringent standards

Engineering Contradiction:

Improveagricultural performanceVSAvoidchemical approval availability

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent replaces complex, heavily regulated adjuvants with simpler, naturally-derived substances (laminarin and common polyols) that are more readily approved by regulatory authorities. This substitution maintains agricultural performance while reducing regulatory barriers, as these natural substances face fewer restrictions compared to synthetic adjuvants.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The formulation allows laminarin to perform multiple functions independently - providing both the biostimulant effect and the stability enhancement without requiring additional auxiliary chemicals. The polyols serve dual purposes as both solvents and stabilizers, reducing the need for separate adjuvants and simplifying the formulation approach.

Inventive Principle:

Principle #25Self-service
