Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid mixing devices require reciprocating or rotating mixing actions, which are not suitable for all applications, and lack the ability to accurately dispense mixed fluids during the mixing process.
Innovation Solution
A multi-chambered mixing apparatus with a primary and secondary chamber, where the back plug's longitudinal movement causes simultaneous dispensing and mixing of substances without the need for reciprocating or rotating motion, using a removable dispensing tip with a mixing chamber to facilitate the mixing of two or more fluids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reciprocating or rotating mixing action is used, then mixing of fluids is achieved, but device complexity and requirement for moving parts increases
Solution Approach 1:
The patent removes the traditional reciprocating or rotating mixing mechanism entirely from the system. Instead of using a mixing shaft with blades that requires complex driving mechanisms, the invention extracts the mixing function and achieves it through simple longitudinal movement of a back plug that forces fluids through a static mixing chamber, thereby eliminating moving parts while maintaining mixing capability
Solution Approach 2:
The patent replaces the mechanical reciprocating or rotating mixing system with a simplified mechanical system based on longitudinal displacement. The back plug's linear movement substitutes for the complex reciprocating or rotating motion, and the mixing is achieved through the interaction of fluids in a static chamber rather than through mechanical agitation
2Stability of the object's composition
If mixing is completed before dispensing, then uniform mixture is achieved, but productivity and speed of application decreases
Solution Approach 1:
The patent performs preliminary mixing action continuously during the dispensing process itself. As the back plug moves forward, it simultaneously forces both fluids into the mixing chamber where mixing occurs, and the mixed fluid is immediately dispensed. This eliminates the need to complete mixing before dispensing, as mixing and dispensing occur concurrently, maintaining both uniformity and productivity
Solution Approach 2:
The patent establishes continuous mixing and dispensing action throughout the operation. The back plug's continuous longitudinal movement ensures continuous forcing of fluids into the mixing chamber, creating a continuous stream of mixed fluid that is immediately dispensed. This continuous process eliminates idle time between mixing and dispensing, maintaining high productivity while ensuring uniform mixing
3Manufacturing precision
If multiple chambers are used for fluid storage, then mixing accuracy improves, but device complexity increases
Solution Approach 1:
The patent divides the fluid storage system into separate chambers (first chamber for first fluid, second chamber for second fluid) to ensure accurate mixing ratios. Each chamber is dedicated to storing a specific fluid, preventing premature mixing and ensuring precise control over the mixing process. The segmentation is achieved through simple longitudinal separation rather than complex multi-dimensional arrangements
Solution Approach 2:
The patent arranges the multiple chambers in a longitudinal dimension rather than using complex spatial arrangements. The first and second chambers are positioned end-to-end along the longitudinal axis, with the back plug moving along this same axis to force fluids into the mixing chamber. This one-dimensional arrangement achieves accurate mixing while minimizing structural complexity
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 efficient and accurate mixing of fluids without moving parts within the mixing chamber, allowing for simultaneous dispensing and mixing, suitable for applications like caulk and colorant mixing, where traditional methods are inefficient.
Implementation Method 1
a movable back plug configured for longitudinal movement along the primary chamber, wherein such longitudinal movement toward the primary chamber dispensing end causes at least a portion of the first substance to exit through the primary chamber dispensing end and at least a portion of the second substance to exit through the primary chamber dispensing end
