Refill Sealing Mechanism for Volatile Substance Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air freshener devices fail to ensure that only original and correctly positioned refills are used, risking the release of toxic volatile substances during diffusion.
Innovation Solution
A refill system with a sealing element that requires correct positioning and complementary threading to allow the release of volatile substances, utilizing an elastic element to maintain a closed position until the refill is properly aligned, ensuring safe and accurate diffusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple wick or pump system is used for transporting volatile substances, then the device complexity is reduced, but the reliability of ensuring correct refill positioning and original refill usage is compromised
Solution Approach 1:
The sealing element is pre-positioned in a locked state that prevents liquid flow before the refill is correctly installed. The elastic element pre-loads the sealing element against the hole, ensuring that no liquid can escape until the activation element is properly positioned to displace the sealing element during correct refill insertion.
Solution Approach 2:
The activation element is housed within a cavity in the diffusing means, and the sealing element is positioned within the refill structure. When the refill is correctly inserted, the activation element engages with the sealing element through nested positioning, triggering the unlocking mechanism without requiring external complex mechanisms.
2Object-affected harmful factors
If no sealing mechanism is used, then the ease of operation is improved, but the harmful effects of accidental release or misuse of toxic volatile substances increase
Solution Approach 1:
The elastic element applies a preliminary counteracting force to the sealing element, holding it in a locked position that actively prevents liquid escape. This anti-action is built into the system before use, requiring specific correct insertion of the refill to overcome the pre-applied sealing force, thereby preventing accidental or incorrect releases.
Solution Approach 2:
The sealing element acts as an intermediary component between the liquid reservoir and the diffusion system. It physically blocks the hole in the partition and can only be displaced by the activation element through correct refill insertion, serving as a safety mediator that prevents direct access to the toxic liquid.
3Reliability
If the sealing element is always open, then the productivity of volatile substance diffusion is improved, but the reliability of preventing toxic substance release increases risk
Solution Approach 1:
The sealing element transitions from a static closed state to a dynamic state where it can be displaced by the activation element during correct refill insertion. This dynamic mechanism ensures the hole remains sealed during storage and transport but opens automatically when the system is properly activated, balancing safety with operational functionality.

AI summary
The diffusion device comprises a refill (1) in which liquid containing the volatile substances is housed, the refill (1) comprising: a hole (2) for the passage of the liquid; a sealing element (3) movable between a closed position in which it prevents the passage of the liquid and an open position in which it allows the liquid to pass through the hole (2); and an elastic element (4) that presses the sealing element (3) into its closed position, wherein the sealing element (3) comprises a housing (8) for housing an activation element (7) that moves the closure element (3) from the closed position to the open position against the action of the elastic element (4). It permits to provide a device that only works when the refill is original and is inserted in the correct position.
