Delivery Engine Reservoir Segmentation for Volatile Material End-of-Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing delivery engines for volatile materials often leave a visible residue at end-of-life, causing consumer confusion and dissatisfaction due to the presence of non-volatile components and incomplete evaporation.
Innovation Solution
The delivery engine features a primary reservoir portion visible to the user and at least one secondary reservoir portion that is not visible, with the secondary reservoir portion positioned gravitationally below the primary reservoir. This configuration ensures that any remaining volatile material at end-of-life is not visible, reducing consumer confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single visible reservoir is used to allow users to see remaining perfume, then users can easily determine how much perfume remains, but visible residue at end-of-life causes consumer confusion and dissatisfaction
Solution Approach 1:
The reservoir is divided into two distinct portions: a first reservoir portion that is visible through the housing front and a second reservoir portion that is not visible. This segmentation allows the visible portion to show perfume availability while the hidden portion captures and conceals the residue at end-of-life, resolving the contradiction between visibility and accurate end-of-life indication.
2Reliability
If the second reservoir portion volume is increased to hold more residue, then consumer confusion is reduced, but the overall device size increases
Solution Approach 1:
The second reservoir portion is designed with a specific volume ratio (at least 4% of initial volatile material volume) optimized to hold the expected residue amount without excessive size. This local optimization ensures the hidden reservoir is just large enough to capture residue and prevent consumer confusion, while maintaining compact overall device dimensions.
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
The solution effectively hides the residual volatile material, clearly indicating the end-of-life of the product and reducing consumer confusion, while ensuring aesthetic benefits and easy usage.
Implementation Method 1
a primary reservoir portion containing an initial volume of volatile material, where the volatile material is configured to evaporate from the primary reservoir portion
Implementation Method 2
at least one secondary reservoir portion; wherein when the delivery engine is oriented for use: at least one secondary reservoir portion is gravitationally below the primary reservoir portion

AI summary
A delivery engine for delivering a volatile material, and an apparatus comprising the delivery engine are provided. The delivery engine may include a primary reservoir portion containing an initial volume of volatile material, where the volatile material is configured to evaporate from the primary reservoir portion after an activation step is performed, and at least one secondary reservoir portion. When the delivery engine is oriented for use, at least one secondary reservoir portion is gravitationally below the primary reservoir portion and a total volume of the at least one secondary reservoir portion that is gravitationally below the primary reservoir portion is above a certain threshold.
