Dual Chamber Storage Device with Piercing Dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for mixing materials prior to use are prone to errors due to inaccurate measurement, combination, and dispensing, especially when dealing with different states of materials like solids, liquids, and semi-solids, which can lead to instability and contamination during storage and handling.
Innovation Solution
A dual chamber storage device with a non-deformable first chamber and a deformable second chamber that allows for separation and precise mixing of materials, featuring a cap and dispenser system that ensures stability and controlled mixing, even when inverted or shaken, with a deformable base that can be pierced or cut to combine materials, and a dispensing tip for precise delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If materials are stored separately in manual mixing systems, then storage stability is improved, but measurement and mixing accuracy deteriorates
Solution Approach 1:
The device divides the storage system into separate first and second chambers that remain isolated during storage, then integrates them through a controlled mixing mechanism. This segmentation allows stable separate storage while the integrated dispenser ensures accurate mixing ratios by design, eliminating manual measurement errors.
2Ease of operation
If materials are mixed manually prior to use, then ease of operation is improved, but reliability of mixing accuracy deteriorates
Solution Approach 1:
The dispenser mechanism automatically performs the mixing function when activated. The user simply operates the dispenser which then reliably combines materials in precise ratios through its integrated design, eliminating the need for manual measurement and mixing operations while ensuring consistent accuracy.
3Productivity
If a deformable second chamber is used for mixing, then mixing effectiveness is improved, but risk of leakage deteriorates
Solution Approach 1:
The second chamber is designed with a deformable base that can be compressed to mix materials effectively. The chamber walls and sealing mechanisms are engineered to maintain integrity during deformation, preventing leakage while allowing the base to flex for thorough mixing of the combined materials.
4Manufacturing precision
If chambers are designed for precise mixing control, then manufacturing precision is improved, but device complexity deteriorates
Solution Approach 1:
The device combines multiple functions into integrated components: the dispenser mechanism simultaneously controls both chambers, the deformable base integrates mixing and sealing functions, and the single actuation system manages both material release and mixing. This merging reduces overall system complexity while maintaining precise mixing control through design integration.

AI summary
A dual chamber storage device includes a first chamber having a base and a hollow body for storing a first material. A second chamber within the hollow body of the first chamber has a base, a hollow body for storing a second material, and a neck portion. A dispenser housed within the second chamber has a hollow body, a dispensing tip, and a cutting edge. A cap surrounds the end of the dispenser with the cutting edge, is rotatingly connectable with the second chamber neck portion, and is non-rotatingly connectable with the first end of the dispenser. When the cap is rotated relative to the second chamber neck portion, the second end of the dispenser moves toward the base of the second chamber and the cutting edge pierces the base of the second chamber thereby allowing the second material to enter the hollow body of the first chamber.
