Polymeric Tank Collar and Foot Ring for Corrosion-Resistant Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressurized tanks, particularly large ones used for industrial or home heating, face issues with insufficient support and corrosion due to water accumulation and exposure to the elements, affecting stability and longevity.
Innovation Solution
A polymeric foot ring and collar design that includes drainage features and releasable attachment systems to prevent water accumulation and corrosion, providing enhanced structural support and protection for tanks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a metal foot ring is used to support the tank, then the tank achieves stable support and uplift from the ground, but the metal foot ring is prone to rust due to water accumulation
Solution Approach 1:
The patent changes the material parameter of the foot ring from metal to polymeric material, which fundamentally alters the corrosion resistance property while maintaining the support function. The polymeric material does not rust or corrode like metal, solving the reliability issue while preserving stability.
Solution Approach 2:
The patent uses polymeric composite materials for the foot ring and collar assemblies. These composite materials combine structural integrity with inherent corrosion resistance, allowing the components to withstand water accumulation and environmental exposure without degrading like traditional metal constructions.
2Object-affected harmful factors
If a metal collar is used to protect valves and regulators, then the valves are protected from damage, but the collar is also prone to corrosion from water accumulation
Solution Approach 1:
The patent changes the material composition of the collar from metal to polymeric material. This parameter change eliminates the corrosion vulnerability of the collar while maintaining its protective function over the valves and regulators. The polymeric collar resists water accumulation and environmental degradation.
3Reliability
If preformed plastic supports are used to reduce rust formation, then corrosion is reduced, but the supports may not provide sufficient weight bearing capacity for large tanks
Solution Approach 1:
The patent employs polymeric composite materials with enhanced structural properties for the foot ring and collar. These composites are designed to achieve both corrosion resistance and sufficient strength to bear the weight of large tanks, resolving the contradiction between material protection and structural capability.
Solution Approach 2:
The patent incorporates ribbing reinforcements and strategically placed support structures within the polymeric foot ring and collar assemblies. These local structural enhancements concentrate strength where needed to bear tank weight while maintaining the overall corrosion-resistant polymeric construction.
