Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corrugated plates used in liquefied gas storage tanks for marine equipment face challenges in maintaining sealability, stability, and material uniformity, particularly at the intersection of transverse and longitudinal corrugations, which affects the overall strength and thermal insulation efficiency.
Innovation Solution
A corrugated plate design with a smooth central top surface and four drawbeads extending from it, where the intersection portion has a unique shape with specific dimensions and profiles, providing improved elasticity, contractility, and strength, and can be used as a sealing layer in storage containers to reduce thermal conductivity and enhance heat preservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional corrugated plate design is used, then manufacturing is simpler, but material uniformity and strength at corrugation intersections deteriorate
Solution Approach 1:
The patent applies local quality by creating a smooth central top surface at the corrugation intersection that is free from corrugation deformations, while the surrounding areas maintain the corrugated structure. This localized smooth region ensures material uniformity and proper material flow during forming, resolving the contradiction between manufacturing simplicity and material quality at critical intersection points.
2Strength
If corrugation height is increased to improve strength, then stability improves, but elasticity and contractility deteriorate
Solution Approach 1:
The patent creates a smooth central top surface at the corrugation intersection that is free from corrugation deformations. This localized smooth region maintains material uniformity and elasticity, while the surrounding corrugated structures provide overall strength. The drawbeads extend from this smooth surface to connect with the corrugations, creating a gradient transition that balances both requirements.
Solution Approach 2:
The patent introduces a vertical dimension by creating a smooth central top surface that rises above the corrugation peaks, forming a three-dimensional structure with a smooth summit region. This dimensional change allows the plate to maintain strength through the corrugation geometry while preserving elasticity in the smooth central region that can deform independently.
3Reliability
If sealing layer thickness is increased to improve sealability, then reliability improves, but thermal insulation performance deteriorates
Solution Approach 1:
The patent creates a smooth central top surface at the corrugation intersection that provides a localized high-quality sealing surface, eliminating the need to increase the entire sealing layer thickness. This smooth region ensures reliable sealing at the most critical area while keeping the overall sealing layer thin, thereby maintaining thermal insulation performance.

AI summary
Disclosed are a corrugated plate having a smooth top surface and drawbeads, and a storage container. The corrugated plate includes a corrugated plate body, a longitudinal corrugation, a transverse corrugation, and an intersection portion. The intersection portion includes a smooth top surface and four drawbeads extending from the top surface to the corrugated plate body. The top surface transitions to the drawbeads smoothly. An overall extension direction of each of the drawbeads intersects a transverse direction, a longitudinal direction, and a height direction perpendicular to the corrugated plate body.
