Dual-Fluid Packaging Device with Breakable Sealing Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices for two fluids, such as liquids and powders, face issues with optimal separation and protection during storage, leading to potential contamination by oxygen and water, and obstacles during mixing and discharge, as seen in prior art devices like DE19917942.
Innovation Solution
A packaging device with a first part containing a breakable element and a second part with a protective layer, where the breakable element is moved by a striking element to release the fluid, and the protective layer is perforated to allow mixing, ensuring optimal packing and preventing obstacles during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable closing element is used to open the first part, then the first part can be opened, but the removable element penetrates the package and forms an obstacle that obstructs optimal mixing and discharge of fluids
Solution Approach 1:
The closing element is segmented into a breakable sealing portion and a non-breakable frame portion. The sealing portion breaks away upon opening to eliminate obstacles, while the frame portion remains to maintain structural integrity and guide fluid flow.
Solution Approach 2:
The harmful obstacle (breakable sealing portion) is extracted from the system by designing it to break away and be removed from the package upon opening, leaving only the beneficial frame portion.
2Ease of operation
If the closing element is moved to the second position before the second part is opened, then the first part is opened, but the process of opening the two compartments is not ensured
Solution Approach 1:
The breakable sealing portion is pre-positioned to break upon movement of the closing element, ensuring that opening of the first part automatically triggers the opening mechanism for proper fluid release.
Solution Approach 2:
The breakable sealing portion acts as an intermediary that transfers the opening action from the closing element to the fluid release mechanism, ensuring proper sequencing without requiring direct user intervention.
3Stability of the object's composition
If the device is designed to separate fluids in a first position, then proper separation is achieved, but no measures are taken to protect fluids from oxygen and water penetration during storage
Solution Approach 1:
The package employs composite materials including aluminum foil layers and plastic materials that provide both separation and protection against oxygen and water penetration during storage, while still allowing fluid release when opened.
Solution Approach 2:
Flexible barrier films and layers are used to seal the package contents, providing protection against harmful factors while maintaining the ability to open and release fluids when needed.
4Object-affected harmful factors
If a protective layer covers the second fluid, then the second fluid is protected, but the protective layer obstructs optimal mixing and discharge of fluids after use
Solution Approach 1:
The protective layer is segmented into a breakable sealing portion that can be easily penetrated or removed to allow fluid mixing and discharge, while maintaining protection during storage.
Solution Approach 2:
The protective layer incorporates perforations or porous sections that allow fluid passage while maintaining overall protective functionality, enabling both protection and mixing/discharge operations.
