Fragrance Capsule Single-Layer Substrate Airflow Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance diffusion systems, particularly dry capsules of polymer beads, lack specific details on substrate positioning, leading to inefficient fragrance release and diffusion, and require higher air flow pressures and flow rates for effective scenting.
Innovation Solution
A fragrance capsule design featuring a frame with two grilles holding substrate elements in a single layer, allowing optimized air circulation and uniform fragrance desorption, reducing air flow requirements and ensuring consistent fragrance release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If substrate elements are arranged in multiple layers, then the fragrance diffusion capacity increases, but the air flow pressure requirements increase and the device complexity increases
Solution Approach 1:
The patent transitions from vertical stacking (multiple layers) to horizontal expansion (single layer with increased surface area). The substrate elements are arranged in a single layer within the capsule, maximizing their exposure to air flow without requiring additional pressure to push air through multiple layers. This dimensional change allows sufficient fragrance diffusion capacity while maintaining lower air flow pressure requirements.
2Quantity of substance
If substrate elements are arranged in multiple layers, then the fragrance diffusion capacity increases, but the device structure becomes more complex
Solution Approach 1:
Instead of adding vertical layers which would require complex support structures, spacing mechanisms, and alignment features, the patent expands the single layer horizontally. This simplifies the capsule structure while maintaining adequate fragrance diffusion capacity through optimized substrate element arrangement and surface area within the single layer configuration.
3Stress or pressure
If substrate elements are arranged in a single layer, then the air flow pressure requirements are reduced, but the fragrance diffusion capacity may be limited
Solution Approach 1:
The patent merges multiple substrate elements into a single continuous layer that maximizes collective surface area. By optimizing the arrangement, spacing, and total surface area of the substrate elements within the single layer, the system achieves sufficient fragrance diffusion capacity without requiring multiple layers, thus maintaining lower air flow pressure requirements while preserving adequate diffusion capacity.
