Vehicle Perfume Diffuser Cartridge Identification and Usage Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle-mounted perfume diffusers lack the ability to accurately determine the usage amount and type of fragrance cartridges, making it difficult for users to manage replacement timing.
Innovation Solution
A vehicle-mounted perfume diffuser system that includes a pair of electrodes and a resistance plate in the fragrance cartridge, where a controller applies a voltage and detects current flow to identify the fragrance cartridge type and calculate usage based on operation intensity and time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a perfume diffuser is mounted in a vehicle to generate fragrance, then the driver can reduce stress while driving, but it is not possible to clearly grasp the usage amount or remaining amount of the perfume diffuser
Solution Approach 1:
The controller measures the resistance value of the resistance plate and calculates the usage amount based on the change in resistance value over time. This feedback mechanism provides real-time information about the remaining perfume amount to the user through the display device, resolving the information loss problem while maintaining the stress reduction benefit.
Solution Approach 2:
The system automatically monitors and calculates the usage amount without requiring user intervention. The resistance plate inherently changes resistance as perfume is consumed, and the controller automatically detects this change and computes the remaining amount, making the system self-monitoring and eliminating the need for manual checking.
2Ease of operation
If a perfume diffuser is mounted in a vehicle to generate fragrance, then the driver can reduce stress while driving, but it is not possible to identify what kind of fragrance is being used
Solution Approach 1:
The controller detects the resistance value of the resistance plate, which is uniquely associated with each fragrance cartridge type. Based on the measured resistance value, the controller identifies the specific fragrance type and displays this information to the user, providing feedback about what fragrance is currently being used while maintaining the stress reduction benefit.
3Ease of operation
If additional devices are installed in the vehicle to stimulate emotions and reduce stress, then the driver can reduce stress while driving, but the device complexity increases
Solution Approach 1:
The controller performs multiple functions: it controls the perfume diffuser operation, measures the resistance value of the resistance plate, calculates the usage amount, identifies the fragrance type, and displays information. By making the controller multi-functional, the patent avoids adding separate dedicated devices for each function, thus reducing overall system complexity while maintaining all necessary features for stress reduction and monitoring.
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 easy identification of fragrance cartridge types and usage tracking, allowing users to timely replace cartridges, thereby reducing manufacturing costs by eliminating the need for additional dedicated controllers.
Implementation Method 1
a resistance plate (21) provided in the fragrance cartridge (20), wherein the resistance plate (21) has a resistance value which changes according to a liquid level of the liquid perfume (100)
Implementation Method 2
the controller (30) identifies the types of the fragrance cartridge (20) based on the size of current flowing through the pair of electrodes (11, 12) and the resistance plate (21)
Data Source
AI summary
A vehicle includes a perfume diffuser including a pair of electrodes, at least one fragrance cartridge including a resistance plate electrically connected to the pair of electrodes, and a controller identifying the types of the fragrance cartridge based on the size of current flowing through the pair of electrodes and the resistance plate.
