Solution Overview

Problem

Existing diffusion devices for volatile substances like insecticides or air-fresheners face issues with safety hazards, fast burning times, and non-uniform release due to reliance on chemical combustion agents, and are not easily customizable.

Innovation Solution

A device using interwoven threads made of natural materials like cotton or linen, impregnated with volatile substances, allows for controlled combustion without additional chemical agents, facilitated by oxygen between threads, and can be impregnated with essential oils for insecticidal or fragrant effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical combustion agents are used to ensure proper combustion, then combustion reliability is improved, but safety hazards and harmful factors increase

Engineering Contradiction:
Improvecombustion reliabilityVSAvoidsafety hazards
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and removes chemical combustion agents from the system. The body is made of natural combustible material (cotton, linen, or other vegetable fibers) that burns without requiring additional chemical additives, thereby eliminating the safety hazards associated with chemical combustion agents while maintaining reliable combustion

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the material parameter of the body from synthetic or chemically-treated materials to natural combustible materials. This parameter change enables the body to self-sustain combustion through its natural fiber structure, which allows oxygen penetration and maintains steady burning without chemical agents

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If combustion paper is used for diffusion, then ease of manufacture is improved, but burning time becomes too fast leading to short usage duration

Engineering Contradiction:
Improveease of manufactureVSAvoidusage time
Core Design Contradiction:
Ease of manufactureVSDuration of action of moving object

Solution Approach 1:

The invention uses a composite structure consisting of natural fiber threads (cotton, linen) woven into a body. This composite material structure provides both ease of manufacture through conventional textile processes and controlled burning characteristics that extend usage time, as the natural fibers burn more slowly and uniformly compared to combustion paper

Inventive Principle:
Principle #40Composite materials

3Duration of action of moving object

If insecticide coils are used for controlled release, then duration of action is improved, but device complexity and manufacturing precision requirements increase

Engineering Contradiction:
Improveusage timeVSAvoiddevice complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The invention applies the self-service principle by using the body's own natural fiber structure to provide the combustion function. The interwoven threads of natural material self-regulate the burning process through oxygen penetration between threads, eliminating the need for complex chemical formulations, combustion agents, or precise manufacturing controls required by traditional insecticide coils

Inventive Principle:
Principle #25Self-service
