Liquid Container Vertical Bars Buckling Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport and storage containers for liquids, particularly those classified as hazardous substances, face challenges in preventing damage to the inner plastic container at lower corner areas during external forces, leading to potential leakage due to buckling of the lattice jacket, which is not effectively addressed without additional corner reinforcements.
Innovation Solution
The design incorporates vertical bars with a depression adjacent to the connecting section, featuring a trough-like depression on the side facing the inner container, allowing for controlled buckling and redirecting forces away from the inner container, thereby preventing damage without the need for additional corner reinforcements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional corner reinforcements are used to prevent damage to the inner container, then the protection of the inner container is improved, but the device complexity and weight increase
Solution Approach 1:
The patent applies local quality by creating a buckling section with a specific geometric configuration (depression with trough opening facing the inner container) at the critical lower corner area of the vertical bar. This localized structural modification provides enhanced protection against buckling forces without requiring additional corner reinforcements throughout the entire structure. The buckling section is specifically positioned where the inner container is most vulnerable to damage from deformed lattice bars.
2Ease of manufacture
If the connecting section is designed with a flattened cross-section to facilitate welding, then the ease of manufacture is improved, but the resistance to buckling forces deteriorates
Solution Approach 1:
The patent segments the vertical bar into distinct functional sections: a connecting section with a flattened cross-section for welding (facing away from the inner container) and a buckling section with a depression (facing toward the inner container). This segmentation allows each section to be optimized for its specific function - the connecting section for ease of manufacture and the buckling section for resistance to buckling forces - thereby resolving the contradiction between manufacturability and structural strength.
3Object-affected harmful factors
If corner reinforcements are added to prevent kinked vertical rods from injuring the inner container, then the safety against damage is improved, but the weight and complexity of the container increase
Solution Approach 1:
The patent implements self-service by designing the buckling section to automatically deflect and redirect buckling forces away from the inner container through its geometric configuration. The depression with the trough opening creates a controlled buckling path that naturally guides the deformed vertical bar away from the inner container, eliminating the need for additional corner reinforcements and thereby reducing the overall weight of the container while maintaining safety.
