Gasket Arrangement With Deformable Seal for Corrosion-Prone Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gasket arrangements for providing fluid-tight seals between mating surfaces in sectional tanks face challenges such as contamination, corrosion, and the need for precise alignment and application of sealants, especially in underwater conditions.
Innovation Solution
A gasket arrangement comprising a first member and a second member, where the second member is capable of deforming the first member while maintaining a fluid-tight seal when compressed, thereby providing a substantially fluid-tight seal between mating surfaces without the need for precise alignment or on-site application of sealants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional gasket arrangement is used, then fluid-tight sealing is achieved, but the gasket is susceptible to contamination and corrosion from fluid contact
Solution Approach 1:
The patent introduces a protective coating as an intermediary layer between the gasket and the fluid environment. This coating acts as a mediator that prevents direct contact between the gasket material and corrosive/contaminating fluids, thereby protecting the gasket while maintaining seal integrity. The coating is applied to the outer surfaces of the gasket, creating a barrier that eliminates the harmful fluid-gasket interaction.
2Reliability
If sealant is applied on-site to ensure fluid-tight sealing, then sealing reliability is improved, but the alignment precision and application difficulty increase
Solution Approach 1:
The patent incorporates sealing features directly into the gasket design during manufacturing, eliminating the need for on-site sealant application. The gasket is pre-configured with integrated sealing elements that provide fluid-tight sealing upon installation. This preliminary action of embedding sealing functionality into the gasket itself removes the requirement for precise on-site alignment and sealant application, thereby improving both reliability and reducing manufacturing precision requirements.
3Object-affected harmful factors
If a robust gasket material is used to resist contamination, then resistance to harmful factors is improved, but the gasket becomes less deformable and harder to seal
Solution Approach 1:
The patent divides the gasket into functional segments: an inner sealing portion made of soft, deformable material that provides the actual seal, and an outer protective portion coated with contamination-resistant material. This segmentation allows each part to optimize its properties - the inner portion maintains deformability for effective sealing while the outer portion provides resistance to contamination and corrosion.
4Manufacturing precision
If precise alignment is required for gasket installation, then seal quality is improved, but the ease of operation and installation difficulty worsen
Solution Approach 1:
The patent designs the gasket with self-aligning features that automatically position the sealing surfaces correctly during installation. The gasket structure includes built-in alignment mechanisms such as tapered edges, guide ribs, or compliant elements that self-adjust to accommodate minor misalignments. This self-service capability eliminates the need for precise manual alignment, thereby improving installation ease while maintaining high seal quality.
