Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air fresheners contain harmful chemicals like phthalates and VOCs, posing health risks, and often produce a uniform fragrance that may not be desirable, lacking customization options and using chemical-based fragrances.
Innovation Solution
A multi-cartridge air freshener system with programmable fan units and compartments for independent fragrance emission, utilizing essential oils that can be customized and switched easily, providing a vegan-friendly, environmentally safe, and biodegradable alternative.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional air fresheners use chemical-based fragrances, then strong fragrance emission is achieved, but harmful chemicals like phthalates and VOCs are released posing health risks
Solution Approach 1:
The patent changes the chemical composition parameter by substituting harmful synthetic fragrances with natural essential oils, thereby eliminating phthalates and VOCs while maintaining fragrance emission functionality through programmable fan control
Solution Approach 2:
The patent extracts and removes harmful chemicals from the air freshener system by using only natural essential oils in cartridges, separating the beneficial fragrance function from the harmful chemical components
2Adaptability or versatility
If conventional air fresheners use single fragrance emission, then simple device structure is maintained, but customization and versatility are limited
Solution Approach 1:
The patent divides the air freshener into multiple independent compartments, each capable of holding different fragrance cartridges and controlled by separate fan units, enabling independent operation and customization of multiple fragrances simultaneously
Solution Approach 2:
The patent creates a multi-functional system where each compartment can independently hold and emit different fragrances, allowing the device to perform multiple fragrance emission functions simultaneously or independently based on user needs
3Ease of operation
If conventional air fresheners emit continuous fragrance, then simple operation is maintained, but controlled and timed emission capability is lost
Solution Approach 1:
The patent transforms the static continuous emission system into a dynamic programmable system where fan units can be controlled to operate at different times, speeds, and durations, allowing flexible and adaptive fragrance emission patterns
Solution Approach 2:
The patent implements periodic fragrance emission through programmable fan units that can be set to operate intermittently at scheduled times, enabling timed and controlled release of fragrances rather than continuous emission
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables controlled release of different fragrances at various times, offering a customizable and healthier air freshening solution that avoids the health risks associated with chemical-based products, providing a pleasant and therapeutic scent experience.
Implementation Method 1
a fan unit disposed within the housing and configured to promote discharge of the fragrance emitting substance from the housing
Data Source
AI summary
An air freshener includes a housing having at least a first compartment and a second compartment, each of the first and second compartments having vents. The air freshener includes a first fan unit disposed within the first compartment and a second fan unit disposed within the second compartment. The air freshener also includes a first fragrance emitting substance disposed within the first compartment proximate the first fan unit and a second fragrance emitting substance disposed within the second compartment proximate the second fan unit. A programmable processor is operatively connected to a power source and the first and second fan units and configured to drive at least one of the first and second fan units so as to promote discharge of one of the first and second fragrance emitting substances from the housing.
