Solution Overview

Problem

Conventional insect repelling vaporizer devices face issues with inconsistent repellant dispersal and safety due to open flames, and electric devices are not portable as they require a line voltage source, limiting their use to specific areas.

Innovation Solution

A portable insect repelling vaporizer device with a body comprising a top and bottom portion, a cartridge adapter, a heating element, and a movable detecting element that only activates the heating element when a cartridge is present, allowing for safe and portable use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a flame is used to vaporize repellant, then the device can be simple in structure, but the dispersal of repellant becomes inconsistent and fire danger increases

Engineering Contradiction:

Improvestructure simplicityVSAvoidrepellant dispersal consistency

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent replaces the mechanical/chemical flame-based vaporization system with an electric heating element system. The electric heater provides controlled, consistent thermal energy to vaporize repellant uniformly, eliminating the inconsistencies and safety hazards of open flames while maintaining structural simplicity through the use of standard electrical components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If an open flame is used, then the device can be portable, but fire safety risks increase and movement is limited

Engineering Contradiction:

ImproveportabilityVSAvoidfire danger

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes the open flame with an electric heating element that can be safely contained within a housing. This eliminates fire hazards while maintaining portability through the use of a battery-powered electrical system that can be moved without risk of burning structures or causing fires.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a housing structure and electrical control system as intermediaries between the power source and the vaporization process. These intermediaries contain the heating process, prevent direct contact with flammable materials, and enable safe movement of the device while maintaining the vaporization function.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If electric vaporizer devices are used, then repellant vaporization is effective, but portability is limited due to reliance on line voltage

Engineering Contradiction:

Improvevaporization effectivenessVSAvoidportability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the power supply system into a portable battery unit separate from the vaporization housing. This allows the device to be used independently of fixed electrical outlets, providing both effective vaporization through the electric heater and full portability through the removable battery pack that can be recharged externally.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a universal power solution by incorporating a rechargeable battery system that can be charged from any standard electrical outlet. This enables the device to function effectively as an electric vaporizer while being fully portable and adaptable to various locations without requiring fixed electrical infrastructure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

If a movable cartridge detecting element is added, then safety is improved by preventing activation without cartridge, but device complexity increases

Engineering Contradiction:

Improvesafety controlVSAvoidcomponent quantity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a self-service safety mechanism where the movable cartridge detecting element automatically engages with the heating element when the cartridge is properly installed. This self-activating design provides reliable safety control by preventing heating only when the cartridge is absent, while the mechanical interaction between the detecting element and heating element keeps the overall component structure relatively simple.

Inventive Principle:

Principle #25Self-service
