Vented Dispensing Device Cover for Accessory Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices lack effective ventilation for storing applicators, leading to issues like mold growth and odor retention, especially when used with liquids, and do not provide a convenient method for storing and drying accessories.
Innovation Solution
A vented dispensing device with a container and a vented cover that creates a ventilated storage volume, allowing airflow to prevent mold growth and odor, and includes a mechanism to confine the dispensing accessory for storage and drying, using a nozzle and trigger system with a vented cover to facilitate airflow around the nozzle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a closed container is used to store the dispensing accessory, then the accessory is protected from contamination, but mold growth and odor occur due to lack of ventilation
Solution Approach 1:
The vented cover incorporates vent openings that allow air circulation through the storage volume. This porous structure enables moisture evaporation and air flow while maintaining the protective enclosure, preventing mold growth and odor accumulation without compromising the accessory's protection from external contamination.
2Ease of operation
If the dispensing accessory is stored inside the container, then it is protected and organized, but it cannot be dried or aerated properly
Solution Approach 1:
The vented cover's vent openings create a controlled porous environment within the storage volume. This allows moisture to escape and air to circulate freely around the dispensing accessory, enabling effective drying and aeration while the accessory remains stored and protected within the container assembly.
3Object-generated harmful factors
If the container is sealed to protect contents, then contamination is prevented, but fragrance dispersal and odor masking are reduced
Solution Approach 1:
The vent openings in the vented cover create a semi-permeable barrier that allows gaseous molecules (fragrances and odors) to pass through while maintaining physical protection. This porous structure enables fragrance dispersal into the environment and allows external odors to be masked by air circulation, without compromising the protective function of the cover.
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 effectively ventilates the storage volume to prevent mold and odor, while keeping the dispensing accessory clean and dry, enhancing the usability and longevity of the device by ensuring the applicator is protected and ready for use.
Implementation Method 1
The vented cover can have a vent opening extending through the vented cover to ventilate the storage volume
Data Source
AI summary
The dispensing device provides dispensable material in a closable container in concert with a corresponding accessory so that the container and the accessory can be commonly stored when not in use, and further provides a ventilated storage volume within the device that can facilitate drying and aerating the accessory.
