Rotating Reservoir Volatile Dispenser for Passive Diffusion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing volatile material dispensing devices have limited diffusion options and high manufacturing and operating costs due to reliance on heating apparatuses and fans, and often operate in a finite number of pre-programmed states with indirect user control over diffusion rates.
Innovation Solution
A volatile material dispensing system with a rotating reservoir and wicking surface, where user-applied force mechanically rotates the reservoir to adjust the amount of volatile material in contact with the wicking surface, allowing direct control over diffusion rates and operating conditions, including passive, boost, and intermediate states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heating apparatuses and fans are used to enhance volatile material release, then diffusion rate is improved, but manufacturing cost and operating cost increase
Solution Approach 1:
The patent extracts and eliminates the heating apparatus and fan components from the volatile material dispensing system. Instead of using these expensive active components, the invention relies on passive diffusion enhanced by a rotatable reservoir mechanism that allows users to control the exposed surface area of volatile material, thereby managing diffusion rate without additional manufacturing or operating costs.
Solution Approach 2:
The system enables self-service diffusion control through manual rotation of the reservoir. Users directly adjust the diffusion rate by rotating the reservoir to expose different amounts of volatile material to the environment, eliminating the need for externally controlled heating or fan systems and their associated costs.
2Productivity
If heating apparatuses and fans are used to enhance volatile material release, then diffusion rate is improved, but operating cost increases due to electrical power requirements
Solution Approach 1:
The patent removes all electrical power-consuming components (heating apparatus and fans) from the system. The diffusion process is entirely passive, relying on natural vapor pressure and user-controlled reservoir rotation to regulate the release rate, thereby eliminating operating costs associated with electrical power consumption.
Solution Approach 2:
The system performs diffusion control through manual user action rather than electrical power. Users rotate the reservoir to adjust exposure, making the system self-sufficient without external energy input, thus eliminating operating costs.
3Ease of operation
If diffusion devices operate in pre-programmed states with indirect control, then device complexity is reduced, but user control over diffusion rate is limited
Solution Approach 1:
The patent implements a dynamic control mechanism where the reservoir can be freely rotated to any position, allowing continuous adjustment of the exposed volatile material surface area. This dynamic adjustment provides direct and precise user control over diffusion rate, contrasting with pre-programmed discrete states while maintaining simple mechanical construction.
Solution Approach 2:
The rotatable reservoir acts as an intermediary mechanism between the user and the volatile material release process. By rotating the reservoir, users indirectly control the amount of material exposed to diffusion, providing intuitive and direct control without complex electronic programming or additional control systems.
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
Enables user-controlled diffusion rates and operating conditions, reducing costs and increasing flexibility beyond traditional devices, while maintaining efficient volatile material release without the need for electrical power.
Implementation Method 1
A reservoir contains a volatile material, wherein the reservoir rotates from a first position to a second position when the at least one engagement member contacts the mechanical assembly
Implementation Method 2
Such rotation may be directly correlated to the amount of volatile material that contacts a wicking surface. The amount of volatile material that contacts the wicking surface, in conjunction with the material type of the wicking surface, directly influences the diffusion rate of the volatile material.
