Refillable Volatile Dispenser Rupture Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing volatile composition dispensers are often non-replenishable and require activation only once, making them difficult to refill and reuse, and they face challenges in maintaining the composition's integrity during storage without leakage.
Innovation Solution
A volatile composition dispenser design featuring a top portion with slots for cartridges and a base portion with a rupture member that activates the cartridges upon rotation, allowing for easy refilling and continuous dispensing through a microporous membrane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a volatile composition dispenser is designed for one-time use with single activation, then the device structure can be simplified, but the device cannot be refilled or replenished
Solution Approach 1:
The dispenser is divided into two main segments: a reusable base portion containing the housing and dispensing mechanism, and replaceable cartridges containing the volatile composition. This segmentation allows the cartridge to be refilled or replaced while the base structure remains intact, enabling refillability without requiring complete device replacement.
Solution Approach 2:
The base portion is designed with universal functionality to accommodate multiple different cartridge types. The activation mechanism and housing structure can work with various cartridge configurations, allowing the same base device to be refilled with different volatile compositions over time, enhancing adaptability.
2Ease of operation
If a volatile composition cartridge is sealed to maintain integrity during storage, then leakage is prevented, but activation becomes difficult when needed
Solution Approach 1:
The cartridge is pre-sealed with a rupturable substrate that maintains integrity during storage. The activation mechanism is pre-positioned in the base portion, ready to puncture the substrate when the cartridge is inserted. This preliminary preparation allows easy activation without compromising storage reliability.
Solution Approach 2:
A rupturable substrate acts as an intermediary barrier between the sealed cartridge interior and the external environment. This substrate can be easily punctured by the activation mechanism's piercing element, allowing controlled release of the volatile composition while maintaining seal integrity during storage and transport.
3Reliability
If a rupturable substrate is used to seal the cartridge, then easy activation is enabled, but the composition may leak during storage
Solution Approach 1:
The rupturable substrate is designed with localized weakness or specific rupture characteristics at the precise location where the activation mechanism will contact it. This local quality allows the substrate to remain intact under normal storage conditions while being easily punctured by the activation mechanism's piercing element when activated.
Solution Approach 2:
The activation mechanism is designed so that the act of inserting and rotating the cartridge automatically engages the piercing element with the rupturable substrate. The system self-activates through the user's natural refilling action, eliminating the need for separate activation steps or complex control mechanisms.

AI summary
A volatile composition dispenser includes a top portion and a base portion. The top portion includes one or more slots for receiving one or more volatile composition cartridges. The base portion includes a rupture member. When the top portion is engaged with the base portion and rotated at least 45 degrees, the rupture member engages and ruptures a rupturable substrate of one or more of the one or more volatile composition cartridges, thereby allowing a volatile composition to be dispensed.
