High-Capacity Mixing Stopper With Helical Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing stoppers have limited capacity and are not suitable for mixing high quantities of substances, particularly for pharmaceutical products that require a solid and liquid mixture, where the solid needs to be dissolved at the time of consumption.
Innovation Solution
A high-capacity mixing stopper composed of four interconnected pieces: a capsule for anchoring, a receptacle with a pouring mouth, a lid for closure, and a helical spring that separates the receptacle from the lid upon threading, allowing for efficient mixing of solid and liquid substances within a bottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a traditional mixing stopper design is used, then the device is simple in structure, but the capacity for containing and mixing substances is limited
Solution Approach 1:
The cap is divided into four independent pieces: an anchoring capsule, a receptacle container, a lid, and a helical spring. This segmentation allows each component to perform its specific function while collectively achieving high capacity for containing and mixing substances. The receptacle container can be enlarged independently while maintaining the overall structural integrity through the modular design.
2Quantity of substance
If the cap is composed of multiple independent pieces, then the capacity for mixing substances increases, but the manufacturing and assembly process becomes more complex
Solution Approach 1:
The four independent pieces (anchoring capsule, receptacle container, lid, and helical spring) are coupled together to form a unified mixing stopper assembly. The anchoring capsule provides a common structure that houses the receptacle container and spring mechanism, while the lid closes the receptacle opening. This merging of components achieves high mixing capacity while maintaining manufacturability through standardized coupling interfaces.
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 design enables secure containment and controlled release of the mixed substances, ensuring accurate dosing and ease of use by allowing the solid to mix with the liquid only when the cap is opened, addressing the capacity limitations of previous designs.
Implementation Method 1
a helical spring responsible for causing the opening of the receptacle... The helical spring is fitted in a compressed manner between the bottom of the capsule and the receptacle container and serves to cause the separation between said receptacle and the closing lid thereof
