Solution Overview

Problem

Traditional pesticidal granules for controlling house flies are prone to lump formation and chemical degradation due to their hydrophilic nature, leading to reduced shelf life and effectiveness, and they often have inconsistent granule sizes that affect luring and visibility.

Innovation Solution

A hydrophobic granular composition comprising an insect controlling agent, food, lure, bitter constituent, luring dye, structure-stabilizer, and tenside, with a specific formulation and manufacturing process to ensure a dust-free, dry product with a narrow granule size range, enhancing both luring efficacy and visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional hydrophilic substrates are used for pesticidal granules, then the bait is palatable and effective initially, but it forms lumps and degrades chemically over time, reducing shelf life

Engineering Contradiction:
Improveshelf lifeVSAvoidchemical stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent changes the fundamental parameter of substrate hydrophilicity to hydrophobicity. By using hydrophobic substrates such as paraffin, microbeads, or hydrophobized materials, the granules resist water absorption and chemical degradation, thereby maintaining their composition stability and extending shelf life without forming lumps.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite material structures where the active ingredient is combined with hydrophobic carrier materials. This composite approach allows the bait to maintain both its pesticidal effectiveness and its physical-chemical stability over time by selecting materials that are inert and resistant to degradation.

Inventive Principle:
Principle #40Composite materials

2Reliability

If granule size is not controlled, then manufacturing is simpler, but luring effectiveness and visibility are reduced

Engineering Contradiction:
Improveluring effectivenessVSAvoidgranule size consistency
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent specifies optimal granule size parameters (0.5-5mm diameter) as a critical quality attribute. This parameter control ensures that granules are small enough to be effective baits but large enough to be visible and removable, balancing manufacturing complexity with performance requirements.

Inventive Principle:
Principle #35Parameter changes
