Solution Overview

Problem

Current repellents against hematophagous arthropods, such as mosquitoes and ticks, either have limited efficacy, short persistence, or come with undesirable side effects, and plant essential oils require large quantities for effective repellency.

Innovation Solution

A composition combining 3,4-dimethoxybenzaldehyde with one or more plant essential oils like litsea cubeba and wintergreen, in specific weight ratios, to enhance repellency and persistence against hematophagous arthropods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If plant essential oil is used as a repellent, then environmental friendliness is improved, but repellent efficacy and persistence are reduced

Engineering Contradiction:
Improveenvironmental friendlinessVSAvoidrepellent efficacy
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The invention combines plant essential oil with 3,4-dimethoxybenzaldehyde to create a composite repellent formulation. This composite approach allows the product to maintain environmental friendliness from the plant-based essential oil while achieving enhanced and prolonged repellent efficacy through the synergistic combination with the specific chemical compound, thereby resolving the contradiction between environmental safety and repellent effectiveness

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention optimizes the concentration ratio of plant essential oil to 3,4-dimethoxybenzaldehyde to achieve maximum repellent effect. By carefully controlling the parameters of the formulation (specific ratios of ingredients), the product achieves both high repellent efficacy and extended persistence while maintaining environmental friendliness, thus resolving the contradiction between efficacy and environmental safety

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If plant essential oil is used as a repellent, then environmental friendliness is improved, but repellent persistency is reduced

Engineering Contradiction:
Improveenvironmental friendlinessVSAvoidrepellent persistency
Core Design Contradiction:
Object-affected harmful factorsVSDuration of action of stationary object

Solution Approach 1:

The composite formulation combining plant essential oil with 3,4-dimethoxybenzaldehyde creates a synergistic effect where the plant-based ingredients provide environmental friendliness while the specific chemical compound extends the duration of repellent action, thereby resolving the contradiction between environmental safety and repellent persistency

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention achieves continuous and prolonged repellent action through the combined formulation. The plant essential oil provides initial repellent effect while the 3,4-dimethoxybenzaldehyde component ensures sustained protection over time, maintaining both environmental friendliness and extended persistency

Inventive Principle:
Principle #20Continuity of useful action

3Reliability

If DEET is used as a repellent, then repellent efficacy is improved, but side effects increase

Engineering Contradiction:
Improverepellent efficacyVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention extracts and utilizes the effective repellent properties from plant essential oil combined with 3,4-dimethoxybenzaldehyde, thereby achieving high repellent efficacy comparable to DEET while eliminating the harmful side effects associated with conventional synthetic repellents like DEET, including skin irritation and environmental damage

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention converts the limitation of plant essential oil (lower efficacy when used alone) into a benefit by combining it with 3,4-dimethoxybenzaldehyde in specific ratios. This transformation creates a formulation that achieves DEET-level efficacy without the harmful side effects, turning the initial weakness into a strength

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
