Fragrance Presentation Device for Head-Mount Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fragrance presentation devices for head-mount displays often present unintended smells due to fragrance leakage and lack the ability to seamlessly switch between different scents, especially when image scenes change.
Innovation Solution
A fragrance presentation device with modular design, featuring fragrance holders positioned away from the presentation area to prevent leakage and conductors that deliver fragrances to presentation modules near the nostrils, allowing for controlled presentation and removal of scents based on user instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fragrance containers are placed in position near the nostrils for presentation, then the fragrance can be presented to the user, but unintended smells occur due to fragrance leakage
Solution Approach 1:
The device is divided into separate functional modules: fragrance storage units are separated from the presentation location. The fragrance container is positioned in a storage chamber away from the nostrils, and only the necessary amount is delivered through conductors to the presentation module near the nostrils, preventing leakage while maintaining presentation capability
Solution Approach 2:
Fragrance conductors act as intermediaries between the fragrance container and the presentation module. These conductors controlledly deliver fragrance from the storage chamber to the presentation location, preventing direct contact and potential leakage of fragrance from containers positioned away from the nostrils
2Duration of action of stationary object
If fragrance is continuously released from containers for a certain period, then the smell presentation function is achieved, but the device cannot switch between different smells when scenes change
Solution Approach 1:
The device enables dynamic switching between different fragrance presentations. Multiple fragrance containers can be selectively activated or deactivated based on scene changes, allowing the system to adapt and present different smells as needed rather than continuously releasing a single fragrance
Solution Approach 2:
The fragrance presentation device is designed to handle multiple fragrance types and presentation modes. The system can selectively present different fragrances corresponding to different scenes, providing multi-functional capability for various smell presentation requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents unintended smell presentation and enables smooth switching between fragrances, ensuring that only the intended scent is experienced by the user, even during scene changes in a head-mount display.
Implementation Method 1
fragrance conductors for conducting the fragrance which has been delivered out of the fragrance holders to the fragrance presentation module
Implementation Method 2
fragrance conductors for conducting the fragrance which has been delivered out of the fragrance holders to the fragrance presentation module

AI summary
The object of the present invention is to provide a fragrance presentation device which prevents an unintended smell from being presented. A fragrance presentation device for use with a display device which can be mounted on the head of a user includes a fragrance presentation module disposed in a fragrance presentation position in the vicinity of the nostrils of a person on which the display device is mounted, a fragrance holder having a fragrance container for holding a fragrance therein, the fragrance holder placing the fragrance container in a position spaced from the fragrance presentation position at least while the fragrance is not presented, and delivering the fragrance out of the fragrance container when the fragrance in the fragrance container is presented, and a fragrance conductor for conducting the fragrance which has been delivered out of the fragrance holder to the fragrance presentation module.
