Removable Powder Container with Bypass Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for mixing powders with liquids, such as in baby bottles, often result in clogging or require external force for mixing, and do not effectively maintain freshness or usability, especially for moisture-sensitive powders.
Innovation Solution
A removable container with a housing that seals within a bottle, featuring a spilling mechanism and bypass element, allowing easy release and mixing of powders or liquids without clogging, and maintaining separation from the liquid until needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cap mechanism is used to allow powder and liquid to mix, then mixing capability is improved, but the powder may clog up the opening during gradual opening
Solution Approach 1:
The container is divided into separate sections: an inner container for powder and an outer container for liquid, with independent access mechanisms. This segmentation allows the powder and liquid to be stored separately and mixed only when needed, preventing clogging while enabling mixing capability.
Solution Approach 2:
The cap is pre-positioned in a closed state sealing the powder container, and the mixing mechanism is pre-configured. When mixing is needed, the cap can be opened in a controlled manner that prevents powder from clogging the opening, and the preliminary arrangement of components facilitates easy mixing without requiring forceful opening.
2Ease of operation
If external force is applied to mix powder and water in a sealed bottle, then mixing can occur, but the operation becomes complex and difficult
Solution Approach 1:
The container is designed so that the act of opening the cap or removing the inner container from the outer container automatically allows the powder and liquid to mix. The system serves itself by using the natural motion of accessing the contents to trigger mixing, eliminating the need for separate external mixing forces or complex mechanisms.
Solution Approach 2:
The container transitions from a static sealed state to a dynamic mixing state through simple mechanical actions. The inner container can be easily removed from or placed into the outer container, and the cap can be opened or closed, creating a dynamic system that mixes powder and liquid on demand without requiring complex external forces.
3Reliability
If powder is stored separately from the liquid bottle, then freshness and usability are maintained, but the mixing mechanism becomes more complex
Solution Approach 1:
The inner container holding the powder is nested within the outer container holding the liquid. This nesting arrangement maintains separation and freshness of the powder while allowing easy access and mixing when needed. The compact nested structure minimizes space and simplifies the overall design compared to separate storage systems.
Solution Approach 2:
The outer container serves multiple functions: it stores the liquid, provides structural support, and acts as the mixing chamber when the inner container is removed or the cap is opened. This multi-functionality reduces the need for separate components and simplifies the overall mixing mechanism while maintaining powder freshness during storage.

AI summary
A removable container for powder or liquid includes a housing, a spilling mechanism and a bypass element. The housing hangs within a bottle and is capable of storing powder within the bottle while being sealed from a precursor liquid held within the bottle. The spilling mechanism enables the powder to spill out of the housing and into the precursor liquid and the bypass element provides the precursor liquid out of the bottle without mixing with the stored powder.
