Perfume Composition Spatial-Temporal Olfactory Profile Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective evaluation and creation of perfumes that exhibit coherent, fast-developing, and prolonged olfactory impact at a distance from their source, particularly under convection flows, due to inadequate understanding of perfume ingredients' behavior in directional air flows.
Innovation Solution
A method for determining the spatial-temporal olfactory profile of perfumes by selecting ingredients based on their volatility and odour detection threshold, using a Distance Perception Boundary Line (DPBL) to ensure reliable detection and recognition at a distance, and a device for generating directional air flows to assess perfume compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If perfume ingredients are selected based on volatility and odour detection threshold using DPBL, then olfactory impact at distance is improved, but evaluation complexity increases
Solution Approach 1:
The patent applies parameter changes by establishing quantitative relationships between volatility, odour detection threshold, and distance perception. The DPBL uses specific parameter thresholds (log volatility ≥ -3, log ODT ≤ 6) to predict perfume performance at distance, transforming qualitative perfume evaluation into a quantitative parameter-based selection process.
Solution Approach 2:
The patent segments the perfume ingredient selection process into distinct evaluation stages: close-range evaluation (traditional), distance evaluation (new), and DPBL-based prediction. This segmentation allows systematic assessment of different perfume performance aspects using appropriate methods for each range, reducing overall evaluation complexity.
2Productivity
If convection flows are used to transport odorants, then olfactory trail is improved, but measurement precision deteriorates
Solution Approach 1:
The patent introduces convection flow as an intermediary mechanism to transport odorants from the source to the detection point. By controlling airflow parameters (velocity, direction, stability), the system enables reliable trail performance while the flow itself acts as a mediator that carries the odorant information through space, decoupling the measurement challenge from the trail performance goal.
3Reliability
If perfume composition is optimized for trail, then sillage is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies parameter changes by defining specific volatility and odour detection threshold ranges for trail-optimized ingredients. The DPBL provides clear parameter boundaries (log volatility ≥ -3, log ODT ≤ 6) that guide ingredient selection and formulation, enabling manufacturers to achieve reliable sillage through parameter-based formulation rather than trial-and-error concentration adjustments.
