Diffusion Device with Segmented Band for Intensity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for diffusing volatile substances, such as perfume, lack accuracy in regulating evaporation surface exposure and are prone to liquid spillage due to lack of a sealing mechanism, making them unreliable for controlling olfactory intensity and preventing accidental leakage.
Innovation Solution
A device comprising a receptacle with a flexible band and a rigid band in contact, where the rigid band is regulated by a complementary inner closing element and a threading-connected regulation element, allowing precise control of the exposed surface and a hermetically sealed mouth to prevent spillage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a flexible band is used to regulate evaporation surface, then the device construction is simple and cost is low, but the positioning accuracy is poor and the band can easily leave the predefined position
Solution Approach 1:
The band is divided into a flexible band and a rigid band segment. The rigid band portion provides stable, predefined positioning at the neck of the receptacle, while the flexible band allows for easy adjustment and movement. This segmentation combines the simplicity of flexible adjustment with the positioning accuracy of rigid structure.
Solution Approach 2:
The device uses a composite structure combining flexible material (for the adjustable band portion) and rigid material (for the positioning portion). This composite approach allows the band to be both easy to move and accurately positioned when engaged with the neck of the receptacle.
2Productivity
If the bottle is opened to allow diffusion, then the volatile substances can be released, but the liquid can be spilled in case of accidental drop or pressure
Solution Approach 1:
The band system provides dynamic control of the opening. When the band is positioned around the neck, it maintains a controlled opening for diffusion. In case of accidental drop or pressure, the flexible band can contract or the rigid band can disengage, allowing the cap to close and prevent spillage.
Solution Approach 2:
The device incorporates a safety mechanism that anticipates accidental drops or pressure. The rigid band's predefined position at the neck and the flexible band's ability to contract provide a cushioning effect that prevents complete opening and potential spillage before an accident occurs.
3Productivity
If the evaporation surface is increased to enhance diffusion intensity, then more volatile substances are released, but the liquid consumption increases
Solution Approach 1:
The device allows users to change the parameter of evaporation surface area by adjusting the band position. Users can select different exposure levels of the band to the atmosphere, thereby controlling the diffusion intensity and liquid consumption rate according to their needs.
Solution Approach 2:
The dynamic adjustment capability allows the evaporation surface to be changed on demand. Users can increase the exposed surface area when high diffusion intensity is needed, and reduce it when lower consumption is desired, providing flexible control over the trade-off between productivity and substance loss.
