Programmable Electronic Sequencer for Independent Fragrance Intensity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air freshening technologies fail to provide a controlled and lasting fragrance experience due to saturation of the olfactory membrane, as they either sequentially activate/deactivate fragrances or alternate between two compositions without allowing independent variation of intensity and combination of multiple fragrances, leading to uncontrolled and gradual transitions and potential inadequate scent combinations.
Innovation Solution
A programmable electronic sequencer with multiple current outlets and a microprocessor that determines which outlets receive current, for how long, and with what intensity, allowing independent control of each device's activation time and intensity, enabling the combination of multiple fragrances and other devices like insecticides or fans for synergistic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sequential activation or deactivation of fragrances is used, then the olfactory membrane saturation problem is addressed, but the fragrance transitions are gradual and uncontrolled, and multiple fragrances cannot be combined in a controlled manner
Solution Approach 1:
The system dynamically adjusts the operational state of multiple vaporizers through a programmable sequencer, enabling flexible transitions between different fragrance combinations, intensities, and durations. The sequencer can independently control each vaporizer's activation timing and intensity levels, allowing precise control over fragrance delivery patterns without fixed sequential limitations.
Solution Approach 2:
The sequencer modifies operational parameters including activation timing, intensity levels, and duration for each vaporizer independently. By varying these parameters programmatically, the system achieves controlled fragrance transitions and combinations, overcoming the gradual and uncontrolled transitions of simple sequential switching while maintaining manageable system complexity through standardized control mechanisms.
2Adaptability or versatility
If multiple vaporizers are activated simultaneously with independent intensity control, then controlled fragrance balancing and combination is achieved, but the device complexity and programming requirements increase
Solution Approach 1:
The programmable sequencer serves as a universal control unit that can manage multiple vaporizers with different fragrance types, activation patterns, and intensity requirements through a single integrated system. This multi-functional approach enables diverse fragrance combinations and delivery patterns without requiring separate control mechanisms for each vaporizer, thereby enhancing versatility while containing overall system complexity.
Solution Approach 2:
The control system segments the management of each vaporizer into independent controllable units, where each vaporizer's activation, intensity, and duration can be individually programmed. This segmentation allows flexible fragrance combinations while maintaining manageable complexity by treating each vaporizer as a separate controllable element within the unified sequencer framework.
3Reliability
If pre-established compatible fragrances are used, then inadequate scent combinations are avoided, but the ability to combine different independent functions and produce synergic effects is limited
Solution Approach 1:
The system dynamically adjusts the operational state of multiple vaporizers through a programmable sequencer, enabling flexible transitions between different fragrance combinations, intensities, and durations. The sequencer can independently control each vaporizer's activation timing and intensity levels, allowing precise control over fragrance delivery patterns without fixed sequential limitations.
Solution Approach 2:
The sequencer modifies operational parameters including activation timing, intensity levels, and duration for each vaporizer independently. By varying these parameters programmatically, the system achieves controlled fragrance transitions and combinations, overcoming the gradual and uncontrolled transitions of simple sequential switching while maintaining manageable system complexity through standardized control mechanisms.

AI summary
A programmable electronic sequencer with a current collector and different current outlets including a microprocessor such that the sequencer program determines which of the possible outlets the current will be directed to, as well as the intensity of this current and the time the current will be supplied for, having a series of thyristors, one for each of the current outlet lines controlled by the microprocessor, in order to control the intensity of the outlet current in each line.
