Bolt-Together Silo Compression Ring Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current particulate material storage bins, such as grain silos, face issues with bolts extending into the interior, limiting interior smoothness, bin size, and weight capacity, increasing assembly time and cost due to numerous small pieces and requiring personnel inside for assembly.
Innovation Solution
A modular, bolt-together silo design with a continuous compression ring and external bolts, featuring a smooth interior and external assembly, allowing for easy expansion and heavier load capacity without internal bolt protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bolts are used to connect panels in traditional bin construction, then structural strength is improved, but bolts extend into the interior of the bin causing rough interior surface and requiring personnel inside for assembly
Solution Approach 1:
The patent inverts the traditional bolt connection arrangement by moving all bolts to the exterior of the bin. Instead of bolts extending through panels into the interior space, the connection system uses external flanges with bolts positioned outside, eliminating interior protrusions while maintaining structural strength through properly designed external connection geometry
Solution Approach 2:
The patent introduces flanges as intermediary elements between panels. These flanges provide external connection surfaces that allow bolts to secure panels together without extending into the bin interior. The flanges act as mediators that transfer structural loads while keeping the interior surface smooth and accessible
2Ease of manufacture
If traditional bolt-together panel construction is used, then assembly is possible, but assembly time and cost increase due to numerous small pieces and complex procedures
Solution Approach 1:
The patent divides the bin structure into modular panel sections with standardized flange connections. This segmentation allows panels to be manufactured separately and assembled efficiently on-site using simple external bolting procedures, reducing overall assembly time compared to traditional methods requiring interior access
Solution Approach 2:
The flange connections are designed to be pre-positioned on panel exterior surfaces during manufacturing. This preliminary preparation of connection elements allows for rapid on-site assembly without requiring complex field fabrication or interior access operations, significantly reducing assembly time and cost
3Ease of manufacture
If traditional bin construction methods are used, then bins can be assembled, but bin size and weight capacity are limited
Solution Approach 1:
The patent employs a dynamic modular design where panels and flanges can be configured in various arrangements to create bins of different sizes and capacities. The standardized external connection system allows the structure to be scaled up or modified without fundamental design changes, enabling larger and heavier-duty configurations while maintaining assembly simplicity

AI summary
A bulk storage bin is provided for grain and particulate material and includes a hopper bottom formed by a plurality of trapezoidal panels, each having upper and lower edges and opposite side edges. Flanges extend outwardly along each edge of each panel to provide a bolted flanged joint for adjacent panels. Plate assemblies extend along the upper edge of each panel to form a continuous 360° compression ring when the panels are assembled. Each flange has a portion extending behind the plate assemblies, with interior bolt holes. An access hole is provided at each end of each plate assembly for access to the interior bolt holes.
