Fragrance Dispenser with Non-Volatile Memory for Precise Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance dispensing devices lack bidirectional data transmission and automatic regulation based on fragrance type and filling level, and do not allow users to read information about the installed fragrance container.
Innovation Solution
A device with a housing containing an electronic data processing unit, a discharge unit for aerosol or gaseous fragrances, and a product container with a non-volatile read-write memory for controlling the discharge unit, enabling information exchange and user-readable data storage, and using a control unit connected to the product container's data processing unit for activating the discharge unit based on stored information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bidirectional data transmission and automatic regulation are implemented, then control precision and user interaction are improved, but device complexity increases
Solution Approach 1:
The patent embeds a data processing unit with non-volatile read-write memory directly within the product container, creating a nested structure where the container holds both fragrance and electronic components. This integration allows bidirectional data transmission between the container's memory and the housing's control unit, enabling automatic regulation of the discharge unit based on stored fragrance information without significantly increasing overall device complexity.
Solution Approach 2:
The product container's integrated data processing unit automatically provides information about the fragrance type and filling level to the housing's control unit. This self-service capability eliminates the need for manual intervention or complex external sensing systems, as the container itself generates and transmits the data needed for precise control and user information display.
2Productivity
If thermal or electrochemical dispensing is used, then fragrance release is improved, but fragrance properties may change undesirably and storage capacity is limited
Solution Approach 1:
The patent employs a discharge unit that delivers aerosol or gaseous fragrances through parameter changes in physical state rather than through thermal or electrochemical processes. This approach allows fragrance release while maintaining the stability of fragrance properties, as the transformation from liquid to aerosol/gas phase occurs without the harsh conditions that could alter chemical composition.
3Volume of moving object
If micro-chambers or micro-tanks are used for fragrance storage, then device size is reduced, but storage capacity becomes small
Solution Approach 1:
The patent uses a product container that is interchangeably fixed in the housing, allowing for modular segmentation. The container can be designed with optimal storage capacity for the desired fragrance quantity, while the overall device remains compact due to the integrated data processing unit and efficient space utilization in the housing. This segmentation allows independent optimization of storage capacity without compromising device portability.
