Replaceable Cartridge Diffusion Device with Venturi Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diffusion devices face challenges in easily changing scents or products, risk cross-contamination, and require frequent cleaning or replacement of diffusion heads due to clogging issues, making them inconvenient for use in public or commercial settings and home applications.
Innovation Solution
A removable and replaceable cartridge system for diffusion devices that includes a housing with a source of compressed gas, a tube, venturi, and mixing areas, allowing for easy switching between scents or products without cross-contamination, and featuring a unitary diffusion head with a gas conduit and liquid conduit in fluid communication with a venturi for efficient dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional reservoirs are refilled directly with liquid, then refilling capability is achieved, but cross-contamination and messy operation occur
Solution Approach 1:
The diffusion device is divided into a permanent housing and a replaceable cartridge. The cartridge contains the reservoir and diffusion head as an integrated unit that can be removed and replaced without refilling, eliminating cross-contamination while maintaining ease of operation.
Solution Approach 2:
The diffusion head is extracted from the permanent housing and integrated into a removable cartridge. This allows the diffusion function to be separated from the reservoir, enabling complete replacement without contact between different liquids.
2Productivity
If diffusion heads have small openings for efficient diffusion, then diffusion efficiency is improved, but clogging susceptibility increases
Solution Approach 1:
The diffusion head is made part of a dynamic system where the entire cartridge can be quickly replaced. This transforms the problem from maintaining static small openings to simply replacing the entire diffusion component when clogging occurs, maintaining high diffusion efficiency without reliability compromise.
Solution Approach 2:
The diffusion head is integrated into a disposable or replaceable cartridge. When clogging occurs, the entire cartridge is discarded or replaced rather than attempting to clean the small openings, ensuring continuous reliable operation while maintaining efficient diffusion performance.
3Adaptability or versatility
If complete scent changing is required, then pure scent diffusion is achieved, but device complexity and cleaning requirements increase
Solution Approach 1:
The device is segmented into a permanent housing and a replaceable cartridge containing both reservoir and diffusion head. This allows complete scent changing by simply replacing the cartridge, achieving pure scent diffusion without requiring cleaning of the diffusion head or complex disassembly procedures.
