Piercable Capsule Flexible Pouch Detachment Suction Sampling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic capsules struggle with sampling components with dynamic viscosities between 0.001 and 500 Pa.s, as these components often stick to the capsule walls or cover, making them inaccessible to suction sampling devices, especially when stored in various positions.
Innovation Solution
A perforable capsule design featuring a flexible pocket inside a rigid body, where the pocket is movable and detachable upon suction, allowing the sampling device to access the component without manual opening, using a hollow needle and suction system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid capsule with a fixed lid is used to package viscous cosmetic components, then the capsule maintains structural integrity and hermetic sealing, but the component becomes stuck to the lid or bottom and inaccessible to sampling devices
Solution Approach 1:
The capsule is divided into two functional parts: a rigid outer body that maintains structural integrity and hermetic sealing, and a flexible inner pouch that contains the cosmetic component. This segmentation allows the rigid body to provide reliable sealing while the flexible pouch enables component accessibility through deformation during aspiration.
Solution Approach 2:
The inner pouch is designed to be flexible and mobile rather than fixed, allowing it to deform dynamically during the aspiration process. The pouch can change shape to facilitate component flow toward the sampling device while maintaining hermetic sealing when in its resting state.
2Adaptability or versatility
If the capsule is stored in various positions, then storage flexibility is improved, but the viscous component sticks to the capsule walls or cover making it inaccessible
Solution Approach 1:
The flexible inner pouch adapts its shape based on storage position and external forces. Whether the capsule is stored upright, inverted, or on its side, the pouch naturally conforms to the component's position, ensuring the component remains accessible for sampling regardless of orientation.
Solution Approach 2:
The flexible pouch automatically adjusts its configuration in response to gravitational forces and aspiration pressure, eliminating the need for manual repositioning or special storage orientations. The pouch self-adjusts to keep the component accessible to the sampling device.
3Manufacturing precision
If a hollow needle and suction system are used to extract the component, then precise dosing is achieved, but the viscous component cannot be extracted because it is stuck to the capsule
Solution Approach 1:
The flexible pouch deforms under the negative pressure generated by the suction system, creating a pathway for the viscous component to flow toward the hollow needle. This dynamic deformation enables complete extraction of the component while maintaining precise dosing control through the aspiration mechanism.
Solution Approach 2:
The flexible pouch acts as an intermediary between the rigid capsule structure and the sampling device. It transmits the aspiration force from the hollow needle to the viscous component, facilitating extraction while the rigid capsule body maintains structural integrity during the process.
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 effective sampling of components with varying viscosities by ensuring the flexible pocket detaches from the rigid body, allowing the suction device to access the component, regardless of the capsule's storage position, while maintaining aseptic and preservative-free packaging.
