Window with Fragrance-Emitting Layer for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices lack enhanced aesthetic and reliability features, particularly in the bezel regions where non-transmissive areas are often used, which can detract from user experience and device appearance.
Innovation Solution
A window and display device design incorporating a fragrance-emitting layer with capsules containing aromatic compounds, an anti-fingerprint layer, and specific bonding layers, which also includes an anti-reflection layer and optical layer to maintain light transmittance and optical properties, while providing fragrance and improved user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fragrance-emitting layer with capsules is added to the window, then aesthetic appeal and user experience are improved, but device complexity increases
Solution Approach 1:
The fragrance-emitting capsules are embedded within the fragrance-emitting layer, which itself is integrated into the window structure. This nested arrangement allows the fragrance function to be incorporated without adding separate external components, thereby enhancing aesthetic appeal while controlling device complexity
Solution Approach 2:
The window is transformed into a multi-functional element that simultaneously serves as a protective cover, an optical element, and a fragrance delivery system. The fragrance-emitting layer integrates scented capsules into the window structure, allowing the same component to provide both visual and olfactory functions
2Reliability
If multiple functional layers are added to the window, then reliability and aesthetic properties are improved, but manufacturing complexity increases
Solution Approach 1:
The window is divided into distinct functional layers including the base layer, fragrance-emitting layer with capsules, anti-fingerprint layer, and anti-reflection layer. Each layer performs a specific function and can be manufactured separately using established techniques, then assembled together. This segmentation allows complex functionality to be achieved through modular construction rather than requiring a single complex manufacturing process
Solution Approach 2:
The window employs a composite structure combining multiple materials with different properties: the base layer provides structural support, the fragrance-emitting layer contains encapsulated aromatic compounds, the anti-fingerprint layer provides protective functionality, and the anti-reflection layer optimizes optical performance. These composite layers are bonded together to create a multi-functional window that maintains high reliability
3Duration of action of stationary object
If the fragrance-emitting layer is made thicker to extend fragrance lifespan, then fragrance durability is improved, but light transmittance decreases
Solution Approach 1:
The fragrance-emitting capsules are designed as thin-walled structures that can be contained in a relatively thin layer. The shell material and thickness are optimized to maintain fragrance retention over extended periods while allowing sufficient light transmission. The thin film approach enables the fragrance layer to provide long-lasting scent emission without significantly compromising optical clarity
Solution Approach 2:
The fragrance emission duration is controlled by adjusting parameters such as capsule wall thickness, fragrance loading concentration, and shell material composition rather than simply increasing the overall layer thickness. This allows optimization of fragrance lifespan while maintaining light transmittance properties

Function Achieved in This Case
The solution enhances the aesthetic appeal and reliability of display devices by offering a fragrance-emitting functionality, extended fragrance lifespan, and maintaining high light transmittance, while ensuring the display device's optical properties and user convenience.
Implementation Method 1
the fragrance source may be released from the shell by pressure applied to an upper surface of the window
Implementation Method 2
an optical layer between the base layer and the fragrance-emitting layer, and a plurality of irregularities may be defined on an upper surface of the optical layer
