Rotating Valve Mixing Device for Precise Liquid Combination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for mixing two-part hair color and similar applications are complex and require high accuracy, often resulting in user errors due to the need for precise mixing of two liquids, which can lead to undesired color outcomes.
Innovation Solution
A device with a rotating valve mechanism that separates two liquids within a housing, allowing for selective storage and precise mixing by external manipulation, preventing accidental mixing until desired, using valve positioning members that exert forces to maintain separation and facilitate mixing when actuated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mixing of two liquids is performed by user, then the process can be simple and accessible, but the mixing precision deteriorates leading to user errors
Solution Approach 1:
The device enables self-service mixing where the system automatically performs the mixing function when activated. The user simply activates the mixing mechanism, and the device internally controls the precise combination of liquids through the valve system, eliminating the need for user skill in achieving proper mixing ratios.
2Stability of the object's composition
If two liquids are stored separately to prevent contact, then the stability of individual liquids is improved, but the device complexity increases
Solution Approach 1:
The device divides the internal storage into separate compartments using a valve mechanism that physically segments the space. This segmentation allows two different liquids to be stored in the same device without contact, maintaining their individual stability while enabling controlled mixing when the valve is activated.
3Manufacturing precision
If precise mixing ratio is required to achieve desired results, then the quality of output is improved, but the ease of operation deteriorates
Solution Approach 1:
The device performs the precise mixing function automatically once activated. The valve system internally controls the exact mixing ratio without requiring the user to manually measure or calculate proportions, thus achieving high precision while maintaining operational simplicity.

AI summary
A device for selectively storing and mixing two liquids. The device comprises a first interior portion for storing a first liquid, a second interior portion for storing a second liquid, and a valve intermediate to the first and second interior portions. The valve moves between at least two positions, a first position preventing the first and second liquids from mixing, and a second position allowing the first and second liquids to mix. The valve includes a first member protruding from a first side and a second member protruding from a second side.
