Solution Overview

Problem

Current ant baits face challenges such as low storage stability, rapid loss of attractiveness to ants, and repellent effects due to high phoxim concentrations, temperature sensitivity, and evaporation issues with liquid baits, limiting their effectiveness and practicality.

Innovation Solution

Ant baits containing an insecticidal active substance and sugar syrup, optionally with an embittering substance like Bitrex, which remain attractive and stable for a long period, using preferred active substances like imidacloprid and sugar syrups like invert syrup, ensuring broad ant acceptance and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If phoxim is used in high concentrations (0.5-1%) to achieve sufficient storage stability, then storage stability is improved, but ants exhibit repellent action and refuse to feed on the bait

Engineering Contradiction:
Improvestorage stabilityVSAvoidrepellent action
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The patent changes the concentration parameter of phoxim from high (0.5-1%) to very low (0.01-0.05%) levels, and compensates by adding sugar syrup (5-50%) and embittering substances (0.01-1%) to modify the bait's chemical composition. This parameter adjustment resolves the contradiction by finding an optimal balance point where stability is maintained without triggering repellent effects.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces sugar syrup and embittering substances as intermediary components that mediate between the phoxim and the ants. These additives serve as carriers and flavor modifiers that enable ants to accept the bait even at very low phoxim concentrations, thereby maintaining stability while avoiding repellent reactions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-generated harmful factors

If phoxim is used in low concentrations (0.05%) to avoid repellent action, then ant acceptance is improved, but storage stability becomes insufficient for practical purposes

Engineering Contradiction:
Improverepellent actionVSAvoidstorage stability
Core Design Contradiction:
Object-generated harmful factorsVSStability of the object's composition

Solution Approach 1:

The patent creates a composite bait formulation combining phoxim (0.01-0.05%), sugar syrup (5-50%), and embittering substances (0.01-1%). This composite material approach allows the system to achieve both low phoxim concentration (avoiding repellency) and sufficient stability through the synergistic interaction of multiple components, particularly the sugar syrup which acts as a stabilizing matrix.

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If liquid baits are used to ensure ant preference and easy intake, then ease of operation is improved, but water content evaporates causing solidification and concentration of active substance leading to repellent effects

Engineering Contradiction:
Improveease of intakeVSAvoidevaporation
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The patent adjusts the water content parameter by using sugar syrup (5-50%) instead of pure water, and adds embittering substances (0.01-1%) to modify the bait's physical and chemical properties. This parameter change reduces evaporation rate while maintaining liquid consistency, preventing solidification and the subsequent repellent concentration effect.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs a disposable bait formulation that is designed to be consumed relatively quickly before evaporation can occur. The combination of sugar syrup and embittering substances creates a bait that maintains attractiveness and liquid consistency throughout its service life, eliminating the need for replacement due to evaporation-induced repellency.

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

4Speed

If phoxim is used to achieve rapid action, then speed of insecticidal effect is improved, but trophallaxis does not occur or occurs only to a small extent, reducing complete eradication of the colony

Engineering Contradiction:
Improvespeed of actionVSAvoidcolony eradication effectiveness
Core Design Contradiction:
SpeedVSProductivity

Solution Approach 1:

The patent changes the concentration parameter of phoxim from moderate to very low levels (0.01-0.05%), which slows down the insecticidal action speed. This parameter change allows sufficient time for trophallaxis to occur, as the slower acting phoxim gives ants time to transport the toxin through the colony via regurgitation and feeding behaviors, thereby improving complete colony eradication.

Inventive Principle:
Principle #35Parameter changes
