Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted aromatherapy devices face issues such as liquid perfumes spilling due to vehicle vibration, safety hazards from flammable components, low volatilization of solid devices, and waste from disposable products that cannot be reused.
Innovation Solution
A vehicle-mounted aromatherapy device with a main body featuring a ventilation structure for air flow from the car's air conditioner, a rotatable fan blade for enhanced volatilization, and a design allowing easy replacement of solid perfume sheets, reducing waste and ensuring stable mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If liquid perfumes are used in automobiles, then the fragrance can keep people clear headed and have a gentle mood, but the liquid perfumes may spill out due to vibration causing pollution and safety hazards
Solution Approach 1:
The patent changes the physical state of the perfume from liquid to solid form. The solid perfume sheet is placed in contact with a heating element that gradually heats it, causing controlled sublimation or evaporation of fragrance. This phase change approach eliminates spilling issues while maintaining effective fragrance diffusion throughout the vehicle interior.
2Reliability
If solid aromatherapy devices are used, then the volatilization speed is low and they do not pollute the automobile interior trim, but the effect of diffusing fragrance is not ideal
Solution Approach 1:
The patent replaces passive solid aromatherapy devices with an active heating system. A heating element (such as a PTC heater or resistive heating wire) is positioned in direct contact with or close to the solid perfume sheet, providing controlled thermal energy to accelerate fragrance volatilization. This mechanical/thermal substitution significantly enhances diffusion efficiency while maintaining the spill-resistant and clean advantages of solid perfume.
3Ease of operation
If disposable aromatherapy devices are used, then they are simple to use, but they do not support replacement of aromatherapy substances resulting in waste of resources
Solution Approach 1:
The patent divides the aromatherapy device into separable components: a reusable base unit containing the heating element and control mechanisms, and replaceable perfume sheets. The perfume sheets can be independently replaced when depleted, while the expensive heating mechanism is reused. This segmentation allows users to maintain simple operation (just replace the sheet) while reducing resource waste through reuse of the base unit.
Solution Approach 2:
The patent implements a system where the consumable perfume sheets are discarded after use, but the valuable heating base unit is recovered and reused indefinitely. This approach separates the disposable aromatic material from the durable functional component, enabling resource recovery and reducing overall waste while maintaining ease of use through simple sheet replacement.
4Productivity
If the air temperature in summer is high, then the liquid perfumes release fragrance quickly, but they contain flammable components and are easy to cause safety hazards
Solution Approach 1:
The patent changes the physical state from liquid to solid and controls the heating temperature to remain below the flash point of flammable components. The solid perfume sheet is heated gradually by a controlled heating element, causing slow sublimation or evaporation. This parameter control (temperature management) maintains effective fragrance release while eliminating fire hazards associated with high-temperature liquid perfume in summer conditions.
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
The device effectively diffuses fragrance without spilling or safety hazards, allows for multiple uses by replacing perfume sheets, and reduces resource waste through a stable and convenient replacement process.
Implementation Method 1
the air flow of the air outlet of the automobile air conditioner is used to accelerate the volatilization of a solid aromatherapy, and the volatilization of the solid aromatherapy is further accelerated by rotating fan blade
Implementation Method 2
the air flow of the air outlet of the automobile air conditioner is used to accelerate the volatilization of a solid aromatherapy
