Dispensing Button Geometry for Homogeneous Fluid Vaporisation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid substance dispensing devices, particularly those using nozzles with pads, are complex and costly due to the moulding and fastening of the pad to the dispenser button, which increases production costs and assembly complexity.
Innovation Solution
A fluid substance dispensing device with a conical or pyramidal surface on the dispensing button, integrated with a spiral groove, minimizes assembly operations and reduces costs by eliminating the need for a separate pad, achieving homogeneous dispersion through a single-piece design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a pad is pressure-fitted into the dispenser button next to the substance delivery channel outlet, then homogeneous vaporisation and considerable turbulence in the substance are achieved, but the production cost and assembly complexity increase significantly
Solution Approach 1:
The patent merges the pad function with the dispenser button by integrating a conical or pyramidal surface directly into the button structure. This eliminates the separate pad component and its associated fastening operations, while maintaining the turbulence-generating function through the geometric surface design.
Solution Approach 2:
The patent uses a conical or pyramidal surface geometry on the dispenser button to generate turbulence in the fluid substance. This curved/geometric surface approach replaces the flat pad structure, achieving homogeneous vaporisation through geometric flow manipulation rather than a separate padded component.
2Manufacturing precision
If a pad is pressure-fitted into the dispenser button, then homogeneous vaporisation is achieved, but production costs increase due to moulding and fastening operations
Solution Approach 1:
The patent combines the pad's vaporisation function with the dispenser button into a single integrated component. This eliminates the need for separate moulding and fastening operations for a pad, reducing production steps and costs while achieving homogeneous vaporisation through the button's conical or pyramidal surface geometry.
Solution Approach 2:
The patent extracts the pad as a separate component and integrates its essential function (generating turbulence for homogeneous vaporisation) directly into the dispenser button structure. This eliminates the need for separate pad production and assembly operations, reducing manufacturing complexity and cost.
3Reliability
If multiple components (pad, dispenser button, nozzle) are assembled separately, then functional performance is achieved, but the number of assembly operations increases
Solution Approach 1:
The patent merges the pad and dispenser button into a single integrated component, reducing the total number of parts that need to be assembled. This maintains functional performance through the geometric design of the integrated button while significantly reducing assembly operations and improving production efficiency.
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 device achieves comparable aerosol homogeneity to devices with pads while reducing production costs and assembly complexity, using a single-piece button with a conical or pyramidal surface and spiral groove for efficient fluid dispersion.
Implementation Method 1
The nozzles of the commonly known kind are rather complex as they have to generate a considerable turbulence in the substance to be dispensed in order to create homogeneous vaporisation
