UV-Triggered Microcapsule Substrate for Smell Information Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies are limited in transferring smell information, as they only convey sounds and images, lacking the ability to effectively diffuse and transmit scent, which is essential for enhancing realism in various applications.
Innovation Solution
A smell-diffusing cell array substrate with microcapsules having a core-shell structure, where the shell contains a photocatalyst and wall material, and the core includes a smell-diffusion material and hydrophilic liquid, is used in conjunction with a UV-emitting device to radiate UV rays, causing the microcapsules to release scent when exposed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional information transfer methods (broadcasting, phones, internet) are used, then sounds and images can be transmitted, but smell information cannot be transferred
Solution Approach 1:
The system segments the information transfer process into separate functional modules: UV-emitting device for activation, microcapsules for smell storage, and wall material for controlled release. This segmentation allows each component to specialize in one function, enabling smell information transfer while maintaining compatibility with existing sound and image transmission infrastructure.
Solution Approach 2:
The patent introduces microcapsules as an intermediary medium between the UV-emitting device and the environment. These microcapsules contain smell-diffusion material and use UV light as a mediator to trigger controlled release, thereby enabling indirect but precise smell information transfer that can be integrated with conventional digital information systems.
2Loss of information
If microcapsules with photocatalyst are used to diffuse smell, then smell information can be transferred, but the structure becomes complex with core-shell design
Solution Approach 1:
The microcapsule employs a nested core-shell structure where the smell-diffusion material is enclosed in the core, surrounded by wall material containing photocatalyst. This nesting allows multiple functional layers to be integrated within a single microcapsule unit, achieving complex smell control functionality without requiring separate external components for each function.
Solution Approach 2:
The wall material is designed as a composite containing both structural components and photocatalyst particles. This composite structure combines the mechanical integrity needed for microcapsule formation with the photochemical properties required for UV-triggered smell release, achieving multiple functions within a single material layer.
3Ease of operation
If UV rays are used to trigger smell release, then controlled smell diffusion is achieved, but additional UV-emitting device components are required
Solution Approach 1:
The system replaces mechanical or chemical trigger mechanisms with optical control using UV light. The UV-emitting device uses electromagnetic radiation to activate the photocatalyst, eliminating the need for mechanical actuators, chemical initiators, or complex electrical switches, thereby achieving precise control with simpler overall system architecture.
