Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-use blister packs integrated with administration devices are fragile and unsuitable for rough environments, such as triage centers, as they can be punctured or have layers separate under stress, making them unreliable for quick and efficient beneficial agent administration.
Innovation Solution
A package arrangement featuring a compartment with a flexible portion that collapses under pressure, hermetically sealed in storage, and includes a rigid insert with a conduit and frame coupling mechanism to restrict motion and ensure fluid communication, providing structural support and preventing seal failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If single-use film containers are used for beneficial agent storage, then the package is lightweight and easy to manufacture, but the container is fragile and can be punctured or have layers separate under stress
Solution Approach 1:
The package combines a flexible film container with a rigid frame structure to create a composite packaging system. The rigid frame provides structural support and protection against puncture and layer separation, while the flexible film container maintains its manufacturing advantages. This composite structure resolves the contradiction by integrating materials with different mechanical properties to achieve both ease of manufacture and high reliability in rough environments.
2Reliability
If a rigid frame is added to support the flexible package, then structural strength and reliability are improved, but device complexity increases
Solution Approach 1:
The package is divided into distinct functional segments: a flexible film container for agent storage and a rigid frame for structural support. This segmentation allows each component to be optimized independently and assembled together, providing the necessary strength without requiring a completely redesign of the entire package structure. The modular approach manages complexity by separating functions into independent elements.
Solution Approach 2:
The flexible film container is nested within the rigid frame structure, with the frame providing external support while the container maintains its flexible properties. This nesting arrangement allows the rigid frame to protect the flexible container without requiring complex integration mechanisms, as the container simply fits within the frame's protective structure.
3Productivity
If the compartment is made flexible to allow collapse under pressure, then dispensing efficiency is improved, but hermetic sealing becomes more difficult to maintain
Solution Approach 1:
The hermetic sealing system combines the flexible film container material with sealing mechanisms integrated into the rigid frame. The frame provides stable mounting points for seals and sealing surfaces, while the flexible container can still collapse during dispensing. This composite sealing approach maintains hermetic integrity even as the container deforms under pressure differentials during the dispensing process.
