Breathing-Synced Scent Ejection Control for Inhalation Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scent ejection systems, such as those described in Patent Literature 1, fail to eject fragrance at appropriate timing, particularly when the door is re-closed, leading to inefficiencies in mood alteration through scent release.
Innovation Solution
A control apparatus that calculates a user's breathing cycle to determine the optimal timing for scent ejection, using a signal generation section to ensure the scent reaches the user during inhalation periods, and includes image processing to target the nose for precise delivery, with optional scent selection and vehicle state detection for personalized scent release.

Engineering Contradiction Analysis
1Extent of automation
If scent ejection is triggered by door closure detection, then the system can automatically release fragrance when user enters vehicle, but the ejection timing is not optimal for user inhalation
Solution Approach 1:
The system performs preliminary detection of user presence and breathing cycle before triggering scent ejection. The breathing cycle detection is conducted in advance to determine the optimal inhalation phase, ensuring the scent is ejected at the precise moment when the user is most likely to inhale, rather than simply reacting to door closure.
Solution Approach 2:
The system continuously monitors the user's breathing cycle and uses this feedback to adjust the scent ejection timing. By detecting the rhythmic motion of the user's chest or face during breathing, the system adapts the ejection moment to coincide with the inhalation phase, creating a closed-loop control that optimizes fragrance delivery based on real-time physiological data.
2Productivity
If scent is ejected without considering breathing cycle, then the system structure remains simple, but the scent delivery efficiency is reduced
Solution Approach 1:
The system utilizes the user's own breathing motion as the trigger mechanism for scent ejection. The breathing cycle detection leverages the natural physiological rhythm of the user without requiring external complex sensors or systems. The user's breathing action itself serves as the control signal, eliminating the need for separate complex control mechanisms while maximizing scent delivery efficiency.

AI summary
[Object] To provide a control apparatus, a control system, a control method, and an ejection apparatus capable of ejecting a scent at an appropriate timing.[Solving Means] A control apparatus according to an embodiment of the present technology includes a calculation section and a signal generation section. The calculation section calculates a breathing cycle based on an output of a body motion detection section that detects a breathing body motion of a user. The signal generation section generates an output signal that causes an ejection section to eject a scent to a predetermined space region based on the output of the calculation section.
