Capsule Liquid Transporting Element for Complete Depletion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic smoking devices often suffer from incomplete liquid depletion in disposable capsules, leading to waste and inconvenience, as the remaining liquid is not fully drawn into the atomizer, posing both commercial and environmental disadvantages.
Innovation Solution
A capsule design featuring a shell with a puncturable membrane and a liquid transporting element, such as a fibrous material with small cavities, ensures that the liquid is efficiently transported to the atomizer by capillary action, minimizing leakage and spillage, and facilitating complete depletion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a disposable capsule is used without a liquid transporting element, then the device complexity is reduced and ease of manufacture is improved, but the liquid is not completely drawn into the atomizer resulting in loss of substance and waste
Solution Approach 1:
The patent applies porous materials (fibrous material with small cavities) as a liquid transporting element within the capsule. This porous structure enables capillary action to transport liquid from the bottom of the capsule to the membrane, ensuring complete liquid depletion and preventing waste, while adding minimal structural complexity to the disposable capsule design.
2Ease of operation
If the capsule is designed without internal liquid transport structure, then ease of manufacture is improved, but liquid leakage and spillage occur during handling and replacement
Solution Approach 1:
The porous fibrous material serves as an internal liquid transport structure that absorbs and contains the liquid within the capsule. This structure prevents liquid leakage and spillage during handling and replacement operations, while the material can be easily integrated into the capsule manufacturing process using conventional techniques.
3Reliability
If a liquid transporting element is added to the capsule, then liquid transport reliability is improved and complete depletion is achieved, but the device complexity increases
Solution Approach 1:
The patent employs a simple porous fibrous material as the liquid transporting element, which relies on natural capillary action rather than complex mechanical or electronic systems. This approach significantly improves liquid transport reliability and ensures complete depletion while adding minimal structural complexity to the disposable capsule.

AI summary
A capsule for use with an electronic smoking device includes a shell (105) having a lateral wall (101, 102) and an end wall (103), wherein the lateral wall (101, 102) and the end wall (103) defines a cavity (110) open at one end (111). A puncturable membrane (104) seals the open end (111) of the cavity (110). A liquid is contained within the cavity (110) by the shell (105) and the puncturable membrane (104), wherein a liquid transporting element (120) is arranged within the cavity (110) enclosed by the puncturable membrane (104) and immersed in the liquid.
