Injection Molded Preform Barrier Layer Composite
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing preforms face challenges in maintaining barrier properties due to hydrophilic materials like nylon, leading to moisture penetration and delamination, and the high cost and limited applicability of expensive barrier layers, as well as the need for additional tertiary materials to enhance mechanical, thermal, and barrier properties.
Innovation Solution
A preform with a secondary material incorporating a tertiary fluid as an initiator or activator forms an internal composite barrier layer, allowing for a controlled addition of tertiary materials with improved mechanical and/or thermal and/or barrier properties, reducing the need for excessive secondary material and minimizing delamination, while maintaining effective barrier functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a barrier layer is produced using expensive materials, then barrier properties are improved, but production cost increases
Solution Approach 1:
The patent uses composite materials by incorporating tertiary barrier materials into the secondary material matrix, creating an internal composite barrier layer that combines the benefits of different materials while reducing overall cost
Solution Approach 2:
The invention applies barrier functionality locally by creating concentrated barrier zones within the preform wall through the incorporation of tertiary materials, rather than using expensive materials throughout the entire structure
2Reliability
If additional tertiary material is introduced to enhance properties, then mechanical and barrier properties are improved, but delamination occurs between layers
Solution Approach 1:
The patent merges the tertiary barrier material with the secondary material by incorporating it as an additive or filler within the secondary material matrix, creating a unified composite structure that eliminates interfacial delamination problems
Solution Approach 2:
The invention creates a composite intermediate layer where tertiary materials are distributed within the secondary material, forming an integrated composite structure that maintains layer stability while enhancing barrier properties
3Reliability
If excessive secondary material is used to ensure barrier functionality, then barrier properties are maintained, but material costs and delamination risk increase
Solution Approach 1:
The patent concentrates barrier functionality in specific zones by incorporating tertiary barrier materials into the secondary material, allowing reduced overall secondary material usage while maintaining effective barrier properties
Solution Approach 2:
The invention uses composite materials to achieve enhanced barrier properties with reduced material quantities, as the tertiary materials provide concentrated barrier functionality within the composite intermediate layer
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
The use of tertiary fluids as a barrier layer enhances the preform's mechanical and barrier properties, reduces material costs, and ensures stable product preservation by minimizing interactions with the environment, achieving excellent lamination and uniformity without delamination issues, even at elevated temperatures.
Implementation Method 1
fluids which naturally have a tendency to disperse homogeneously in a certain volume
Implementation Method 2
