Offset Laminate Seam for Storage Bin Panel Tearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional particulate storage bins face failures due to significant outward forces from stored materials, particularly grain, which cause tearing of sheet metal panels at the seam connections, even when stronger bolts are used, as they create a single shear point leading to structural weaknesses.
Innovation Solution
An offset laminate seam system where three or more panels are connected with multiple vertical rows of end fasteners to form a ring structure, distributing forces and reducing the likelihood of panel tearing, allowing for either fewer or smaller bolts to be used while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If stronger bolts are used to prevent failure at single shear points, then the bolt capacity is improved, but the sheet metal panels still tear due to significant forces at distal ends
Solution Approach 1:
The invention divides the continuous seam into multiple discrete connection points by using offset laminate seams with multiple horizontal seams spaced vertically apart. This segmentation distributes the circumferential force from stored particulate materials across multiple separate bolt groups rather than concentrating it at a single shear plane, thereby preventing panel tearing even when using standard bolt specifications.
Solution Approach 2:
The invention transitions from a single-plane shear connection to a multi-dimensional distribution by spacing horizontal seams at different vertical positions. This creates multiple shear planes distributed along the vertical dimension, transforming a one-dimensional force concentration problem into a multi-dimensional force distribution solution that enhances overall seam strength.
2Device complexity
If only two panels are connected together creating a single shear point, then the device complexity is reduced, but the bolt capacity is insufficient to handle outward forces from stored materials
Solution Approach 1:
The seam is segmented into multiple horizontal seams spaced vertically apart, with each seam containing multiple bolts arranged in vertical rows. This segmentation increases the total bolt capacity to handle outward forces from stored materials while maintaining relatively simple individual connection elements, achieving a balance between complexity and strength.
Solution Approach 2:
Multiple panels are merged through a composite seam construction where horizontal seams and vertical seams intersect to form a lattice-like pattern. This merging of multiple connection systems creates a distributed fastening network that provides superior bolt capacity while using standard panel and fastener components.
3Stability of the object's composition
If three or more panels are connected with multiple vertical rows of end fasteners to form a ring structure, then the force distribution is improved, but the device complexity increases
Solution Approach 1:
The complex force distribution problem is solved by segmenting the seam into standardized modular units (horizontal seams with vertical rows of bolts). Each module is identical and can be assembled independently, providing stable force distribution across the entire ring structure while reducing construction complexity through standardization.
Solution Approach 2:
The horizontal and vertical seam patterns serve multiple functions simultaneously: they distribute forces from stored materials, provide structural rigidity, and enable modular assembly. This multi-functionality achieves stable force distribution without proportionally increasing construction complexity.

AI summary
An offset laminate seam system for storage bins for increasing the capacity of bolts in a seam of a storage bin. The offset laminate seam system for storage bins generally includes three or more panels connected together with two or more vertical rows of end fasteners to form a vertical seam. The interconnection of three or more panels continues to form a ring structure. A plurality of the ring structures are stacked upon one another and attached together with fasteners to form the wall of the storage bin and a roof is attached to the uppermost ring structure.
