Removable cartridge for liquid diffusion device with a cartridge insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid diffusion devices face challenges in efficiently refilling and replacing scents or products, often resulting in messy bulk refills, leakage, contamination, and complex, costly cartridge systems.
Innovation Solution
A removable cartridge with a multi-functional insert that includes a tortuous passage to reduce liquid particle size, preventing leakage and allowing for easy replacement, featuring a venturi device for atomization and a convoluted flow path to ensure only fine particles are discharged, with a design that prevents liquid from leaking when the cartridge is upended.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional refilling methods are used, then the reservoir can be refilled with new liquid, but the process becomes messy and creates contamination risks
Solution Approach 1:
The diffusion device is divided into a permanent housing and a removable cartridge. The cartridge contains the liquid reservoir and can be easily removed and replaced without messy refilling. This segmentation allows the liquid-containing component to be disposed of or replaced cleanly, eliminating contamination risks associated with traditional refilling.
Solution Approach 2:
The cartridge is designed as a disposable or replaceable component that contains the liquid reservoir. When the liquid is depleted, the entire cartridge is removed and replaced with a fresh one, eliminating the need for refilling operations that could cause mess or contamination. This approach trades the cost of replacing cartridges for the cleanliness and convenience of no-refilling-required operation.
2Ease of operation
If a removable cartridge system is implemented, then refilling becomes easier, but the device complexity increases
Solution Approach 1:
The device is segmented into a permanent housing containing the motor and control electronics, and a removable cartridge containing the liquid reservoir and diffusion components. This segmentation simplifies the overall system architecture by separating the complex permanent components from the simple disposable cartridge, making the replacement process straightforward despite the added modular structure.
Solution Approach 2:
The permanent housing is designed with a universal interface that can accommodate different cartridge types or configurations. The housing contains all the complex mechanisms (motor, sensors, controls) that work with various cartridges, allowing the system to handle multiple functions through a single standardized interface, thereby managing complexity efficiently.
3Ease of operation
If the cartridge is designed for easy removal, then cartridge replacement becomes simpler, but leakage risks increase
Solution Approach 1:
The cartridge is completely extracted from the housing as a self-contained unit. All liquid-containing components, seals, and diffusion elements are integrated into the cartridge itself. When removed, no liquid remains in the housing, eliminating leakage risks. The cartridge can be easily replaced without concern for leakage because the extraction is complete and the housing is left empty and clean.
Solution Approach 2:
The cartridge is designed as a disposable component that is sealed and self-contained. Once removed from service, it is discarded rather than refilled or reused, eliminating the need for complex sealing mechanisms that would be required for reusable cartridges. The simplicity of the disposable design allows for easy removal while maintaining reliability through proper sealing during its service life.
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 enables efficient, mess-free refilling and effective diffusion of fine particles, reducing leakage and contamination risks while maintaining the integrity of the diffused liquid, making it suitable for commercial and home use.
Implementation Method 1
a diffusion head positioned within the internal housing cavity, which includes a venturi device for generating a diffused liquid from the liquid contained in the internal housing cavity
Implementation Method 2
a tortuous passage extending between the inlet and the outlet zone to aid in further reducing an average particle size of the diffused liquid as the diffused liquid moves through the tortuous passage

AI summary
An insert of a cartridge for use with a liquid diffusing device is provided. The insert includes a body, an inlet provided in the body to receive diffused liquid generated within the cartridge during operation of the liquid diffusing device, an outlet zone defined at least in part by the body through which to discharge the diffused liquid toward an external environment, and a tortuous passage extending between the inlet and the outlet zone to aid in further reducing an average particle size of the diffused liquid as the diffused liquid moves through the tortuous passage. Removable cartridges for use with a diffusion device are also provided which include such an insert.
