Solution Overview
Problem
Existing odor presentation technologies fail to effectively control the presentation of odors to users, leading to discomfort due to variations in wind pressure and duration, which affects the perceived impression of the odor, limiting the expression of odors to either local or drifting types.
Innovation Solution
An odor presentation module with a first and second airflow system, where the first airflow containing an odor exits through a first opening and a second airflow exits through a second opening, allowing the movement of the first airflow to be controlled by the second airflow, enabling adjustment of flow velocity and direction to achieve various odor expressions, including local and drifting types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If an odor is injected by an injection device such as a spray, then the odor can be delivered to the user, but the user perceives wind pressure at the same time and the perception time is short
Solution Approach 1:
The invention divides the airflow into two separate systems: a first airflow for odor delivery and a second airflow for controlling the odor plume. This segmentation allows independent optimization of each airflow's characteristics, enabling fast odor delivery without the harmful wind pressure sensation by using a gentler second airflow to carry the odor plume to the user.
Solution Approach 2:
The second airflow acts as an intermediary that carries the odor plume from the first airflow to the user. Instead of directly injecting odor-laden airflow at high speed, the system uses the second airflow as a mediator to gently transport the odor, eliminating the wind pressure sensation while maintaining effective odor delivery.
2Speed
If an odor is injected by an injection device such as a spray, then the odor can be delivered to the user, but the perception time is short
Solution Approach 1:
By separating the odor delivery function (first airflow) from the odor plume transport function (second airflow), the system can maintain a sustained odor presence. The second airflow continuously carries the odor plume to the user, extending the perception duration while the first airflow provides rapid odor generation.
Solution Approach 2:
The second airflow provides continuous odor plume transport to the user, ensuring sustained odor perception. Unlike direct injection that delivers odor in brief pulses, this system maintains a continuous flow of odor-laden air, extending the duration of odor perception while keeping the delivery mechanism efficient.
3Device complexity
If a single airflow system is used, then the device structure is simple, but the odor expression is limited to either local or drifting types
Solution Approach 1:
The invention segments the airflow system into two independent controllable flows, enabling flexible combination of different airflow patterns. This allows the system to switch between local odor presentation (strong first airflow with weak second airflow) and drifting odor presentation (weak first airflow with strong second airflow), achieving versatile odor expression while maintaining manageable device complexity.
Solution Approach 2:
The system dynamically adjusts the relative strengths and directions of the two airflows to achieve different odor presentation modes. By varying the flow rates and directions of the first and second airflows independently, the system can adapt to different odor expression requirements, transitioning between local and drifting odor types as needed.
