Solution Overview

Problem

Existing outdoor insect repellent systems are not effectively portable, easy to set up, or efficient in creating a mosquito-free zone, and often require complex maintenance and fuel replenishment.

Innovation Solution

A portable insect repellent system powered by a hydrocarbon fuel cartridge, mounted on a pole that can be staked into the ground or held in a moveable base, which disperses insect repellent and allows for easy replacement of fuel cartridges and integration of additional functional elements like lights and scented pads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a portable insect repellent system is designed for easy setup and movement, then portability and ease of operation are improved, but maintaining a substantial insect-free zone becomes more difficult

Engineering Contradiction:
Improveease of setupVSAvoideffectiveness of insect-free zone
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system divides the insect repellent function into multiple independent devices positioned around the perimeter. Each device operates autonomously with its own fuel cartridge and heating element, allowing the overall zone protection to be achieved through distributed units rather than a single complex system. This enables easy setup and movement while maintaining effective coverage through coordinated placement of multiple units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pole-mounted device serves multiple functions: it provides structural support for the heating element, holds the fuel cartridge, positions the insect repellent dispersal mechanism at optimal height, and can accommodate additional functional elements like lights and scented pads. This multi-functionality consolidates what would otherwise require multiple separate components into a single portable unit.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple functional elements are integrated into the pole-mounted device, then versatility is improved, but device complexity increases

Engineering Contradiction:
Improvefunctional elements integrationVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Additional functional elements such as lights and scented pads are nested within the existing pole-mounted housing structure. The housing contains compartments and mounting mechanisms that accommodate these optional elements without requiring a complete redesign of the base device. Users can configure the device with only the essential insect repellent components or add optional elements as needed.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The device configuration is made dynamic and adjustable rather than fixed. Optional functional elements can be added or removed from the pole-mounted housing depending on user needs. The modular design allows the system to adapt its complexity level - users can start with a simple insect repellent device and progressively add functional elements like lights or scented pads only when required.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the system uses a portable fuel cartridge for easy replacement, then ease of operation is improved, but fuel efficiency and duration of action may be reduced

Engineering Contradiction:
Improvefuel replacement easeVSAvoidoperational duration
Core Design Contradiction:
Ease of operationVSDuration of action of moving object

Solution Approach 1:

The system is designed to be quickly reconfigured with a new fuel cartridge without requiring complex disassembly or specialized tools. The pole-mounted device includes accessible compartments and simple connection mechanisms that enable users to perform fuel replacement themselves in a straightforward manner, maintaining operational continuity with minimal interruption.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system operates in periodic cycles where the heating element cycles on and off to vaporize the insect repellent from the impregnated mat. This periodic operation optimizes fuel consumption by heating only when needed to maintain effective vapor concentration in the zone, rather than continuous heating that would waste fuel. The cycle timing is calibrated to maintain protective vapor levels while extending operational duration between fuel cartridge replacements.

Inventive Principle:
Principle #19Periodic action
