Solution Overview

Problem

Existing tackifiers for hydraulic applications in ground surface treatments face challenges such as high cost, limited solubility, and poor dispersion, leading to inefficient mixing, adhesion, and erosion resistance, particularly in water and wind exposure scenarios.

Innovation Solution

A novel tackifier formulation combining modified starch treated with a borate-containing solution and acrylamide, which enhances solubility and dispersibility, reducing lump formation and improving viscosity, adhesion, and resistance to water and wind erosion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional tackifiers are used for hydraulic applications, then adhesion and erosion resistance are provided, but cost is high and solubility and dispersion are limited

Engineering Contradiction:
Improveadhesion and erosion resistanceVSAvoidsolubility and dispersion
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines modified starch and acrylamide to create a composite tackifier formulation. The modified starch provides solubility and dispersion benefits while the acrylamide component enhances adhesion and erosion resistance, achieving both reliability and ease of manufacture through material composition rather than relying on a single substance with limited properties

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent modifies the physical and chemical parameters of starch through treatment processes to improve its solubility and dispersion characteristics. By changing the molecular structure and properties of the starch (e.g., degree of substitution, particle size distribution), the formulation achieves better mixing efficiency while maintaining the required adhesion and erosion resistance

Inventive Principle:
Principle #35Parameter changes

2Reliability

If traditional tackifiers are used, then adhesion is achieved, but mixing efficiency is poor due to limited solubility and dispersion

Engineering Contradiction:
ImproveadhesionVSAvoidmixing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The composite formulation of modified starch and acrylamide creates synergistic effects where the modified starch component provides excellent solubility and dispersion, enabling efficient mixing, while the acrylamide component ensures adequate adhesion performance. This division of functional responsibilities within the composite resolves the contradiction between adhesion reliability and mixing productivity

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The modified starch undergoes parameter changes including molecular weight reduction and increased hydrophilicity through chemical modification, which significantly improves its dissolution rate and dispersion uniformity in water, thereby enhancing mixing efficiency without compromising the final adhesion strength of the cured formulation

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If existing tackifiers are used for erosion control, then some resistance is provided, but performance in water and wind exposure is poor

Engineering Contradiction:
Improveerosion resistanceVSAvoidperformance under water and wind exposure
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent develops a composite tackifier system where modified starch and acrylamide work synergistically to provide enhanced resistance against both water erosion and wind erosion. The formulation creates a more robust protective matrix that maintains integrity under combined environmental stresses, achieving reliable performance across multiple harmful factors rather than resistance to a single type of erosion

Inventive Principle:
Principle #40Composite materials

4Reliability

If traditional tackifiers are used, then ground surface treatment is achieved, but cost is high

Engineering Contradiction:
Improveground surface treatment effectivenessVSAvoidcost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent replaces expensive traditional tackifiers with a cost-effective formulation based on modified starch, which is derived from abundant renewable resources. The acrylamide component is used in optimized quantities to provide necessary performance enhancement, creating an economical formulation that achieves ground surface treatment effectiveness at lower material cost

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The composite formulation allows for cost optimization by combining a low-cost base material (modified starch) with a smaller amount of performance-enhancing additive (acrylamide). This hierarchical structure provides effective ground surface treatment while minimizing the quantity of expensive substances required, thereby reducing overall treatment cost

Inventive Principle:
Principle #40Composite materials
