Intermediary Sheet Metal Container for Flammable Liquid Fire Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportation and storage containers for liquids require frequent refilling into special containers to meet fire protection regulations when storing highly flammable liquids, which is inconvenient and may not ensure adequate fire resistance.
Innovation Solution
Incorporating an intermediary sheet metal container between the inner plastic container and the outer metal jacket, with a container lid and support base, to enhance fire resistance and prevent liquid leakage, while maintaining minimal weight increase and allowing for conventional top-loading and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an intermediary container is added between the inner container and outer jacket, then fire resistance is improved, but device complexity increases
Solution Approach 1:
The patent implements a nested container structure where the intermediary sheet metal container is placed inside the outer jacket and surrounds the inner plastic container. This nesting arrangement provides enhanced fire resistance through the fire-resistant sheet metal layer while maintaining a compact overall structure, resolving the contradiction between improved reliability and increased device complexity.
Solution Approach 2:
The intermediary sheet metal container acts as a mediator between the inner plastic container and the outer jacket. It provides the necessary fire resistance for storing highly flammable liquids while allowing the inner container to remain relatively simple. This intermediary layer resolves the technical contradiction by providing fire protection without requiring complete redesign of the entire container system.
2Reliability
If an intermediary container is added between the inner container and outer jacket, then fire resistance is improved, but weight increases
Solution Approach 1:
The patent applies local quality by using the fire-resistant sheet metal intermediary container only in the specific area where fire protection is needed - between the inner container and outer jacket. This localized application of fire-resistant material provides the necessary fire resistance for highly flammable liquids without requiring the entire container structure to be heavily reinforced, thus minimizing weight increase while improving reliability.
3Ease of operation
If the container lid is detachably connected, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamics by making the container lid detachably connected to the intermediary container rather than permanently fixed. This allows the lid to be removed for cleaning and maintenance operations, improving ease of operation. The detachable connection mechanism enables dynamic reconfiguration of the container assembly for maintenance while maintaining structural integrity during normal use.
