Sensor-Guided Fragrance Dispensing for Consistent Personal Scent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Humans are desensitized to their own body odors due to olfactory adaptation, making them unaware of their fragrance levels, which can lead to perceived odor intensity fluctuations.
Innovation Solution
A portable dispensing device equipped with sensors and a controller that adjusts fragrance release based on user data, including heart rate, humidity, and location, to maintain a desired scent level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a portable dispensing device is used to maintain fragrance levels, then the user's scent consistency is improved, but the device complexity increases due to multiple sensors and controllers
Solution Approach 1:
The portable dispensing device integrates multiple functions including fragrance storage, sensor monitoring (accelerometer, altimeter, humidity sensor, heart rate monitor, thermometer, GPS), and automated dispensing control into a single device. The controller processes data from all sensors and coordinates the dispenser to maintain optimal fragrance levels, making the device universally functional for both personal care and environmental monitoring.
Solution Approach 2:
The device automatically monitors the user's physiological data and environmental conditions through integrated sensors, then self-regulates fragrance dispensing without user intervention. The controller continuously adjusts dispensing based on real-time sensor input, enabling the system to maintain fragrance levels autonomously based on the user's activity state and surroundings.
2Adaptability or versatility
If sensors continuously monitor user data to adjust fragrance release, then the adaptability to user conditions is improved, but the energy consumption increases
Solution Approach 1:
The device employs periodic sensing and dispensing actions rather than continuous operation. Sensors activate at intervals to collect user data, and the dispenser releases fragrance in periodic pulses based on accumulated sensor data analysis. This approach maintains adaptability to user conditions while significantly reducing energy consumption compared to continuous monitoring and dispensing.
Solution Approach 2:
The device changes operational parameters dynamically based on user state. When sensors detect increased physical activity (through heart rate, temperature, or motion data), the system adjusts fragrance release rate and timing parameters. During low-activity periods, monitoring frequency and dispensing rates are reduced, optimizing energy usage while maintaining fragrance effectiveness.
3Measurement precision
If multiple sensors are integrated to detect user state and environment, then the measurement precision of user conditions is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple independent sensors (accelerometer, altimeter, humidity sensor, heart rate monitor, thermometer, GPS) into a single integrated portable device housing. The controller consolidates data processing from all sensors, merging their functions into a unified system that monitors both user physiological state and environmental conditions, thereby achieving high measurement precision without proportionally increasing overall device complexity.
