Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trigger-dispensing devices for multiple liquids often fail to achieve a good mixture of substances, frustrating their intended purpose of providing an accentuated action in applications like home hygiene.
Innovation Solution
A trigger-dispensing device with a dispensing head that includes pumping means for simultaneous aspiration and pre-compression of two or more substances before dispensing, ensuring effective mixing by separating and compressing them before combination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple substances are dispensed simultaneously without pre-compression, then the device structure remains simple, but the mixing quality of substances deteriorates
Solution Approach 1:
The patent applies preliminary action by implementing pre-compression chambers that compress substances before they are dispensed. The compression mechanism prepares the substances in advance, ensuring proper mixing and pressurization occurs within the chambers before ejection, thereby resolving the mixing quality issue without requiring complex external mixing devices.
2Manufacturing precision
If pre-compression is applied to multiple substances before dispensing, then mixing quality improves, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated dispensing head structure. The compression chambers, valve mechanisms, and dispensing nozzles are combined into one unified component assembly, reducing the number of separate parts and simplifying the overall device structure while maintaining the pre-compression mixing functionality.
Solution Approach 2:
The dispensing head is designed as a multi-functional component that simultaneously performs compression, mixing, valve control, and dispensing operations. This universal design allows a single component to execute multiple operations that would otherwise require separate devices, thereby reducing overall device complexity.
3Manufacturing precision
If substances are compressed separately before mixing, then mixing effectiveness improves, but the number of components increases
Solution Approach 1:
The patent employs a nested structure where one compression chamber is positioned inside another, with the first compression chamber containing the first substance and the second compression chamber containing the second substance. The chambers are arranged concentrically or adjacently within the same dispensing head housing, allowing separate compression of multiple substances while using a single integrated component structure rather than multiple separate devices.
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 excellent mixing of substances both within the device and on surfaces, enhancing the effectiveness of the combined action and simplifying assembly with a fast and efficient snap connection mechanism.
Implementation Method 1
pumping means operable by the trigger to aspirate simultaneously at least two substances and achieve dispensing, wherein the means for pumping are in addition suitable for carrying out a predetermined pre-compression of these substances
