Rigid Discharge Structure for Container Liner Slippage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container liners face challenges such as difficulty in installation, interference with container operations, and material compatibility issues, particularly in ensuring non-contamination of fluids and meeting performance demands in various applications.
Innovation Solution
A container liner discharge structure featuring a collar, a substantially rigid section, and a neck, all fabricated from the same liner material, which encapsulates an O-ring and provides a passageway, ensuring compatibility and preventing slipping, with the rigid section having a greater cross-sectional thickness than the liner body for enhanced structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the liner material is made thinner to reduce weight and cost, then the ease of manufacture and cost are improved, but the structural strength and resistance to slipping deteriorate
Solution Approach 1:
The discharge structure incorporates a rigid section with greater thickness than the flexible section, creating local reinforcement where structural strength is needed while maintaining thin walls elsewhere for ease of manufacture and cost reduction
Solution Approach 2:
The discharge structure combines rigid and flexible sections of the same material with different thicknesses, creating a composite structure that achieves both strength and manufacturability
2Adaptability or versatility
If different materials are used for different sections of the liner to meet performance requirements, then the functional performance is improved, but the manufacturing complexity and material compatibility issues worsen
Solution Approach 1:
The entire discharge structure is made from the same material as the liner body, ensuring material compatibility and simplifying manufacturing while achieving different functional requirements through geometric variation rather than material variation
Solution Approach 2:
Instead of changing materials to meet different performance requirements, the invention changes physical parameters such as thickness and rigidity while maintaining material homogeneity throughout the structure
3Adaptability or versatility
If the liner is made more flexible to conform to the container interior, then the adaptability to container shapes is improved, but the stability and resistance to slipping worsen
Solution Approach 1:
The discharge structure has a rigid section that provides stability and slip resistance, while the flexible section maintains conformity to the container interior, achieving both adaptability and reliability through localized structural differentiation
