Solution Overview
Problem
The existing processing and storage facilities for particulate materials face challenges in connecting conduits with differing cross-sectional shapes, as manufacturing and installing adapters to transition between these shapes is difficult, costly, and time-consuming.
Innovation Solution
A transition adapter system comprising a crown piece with an elliptical sectional shape and a box piece with a rectangular sectional shape, formed by bending metal halves, which are joined to provide a smooth transition between conduits with different cross-sectional shapes, allowing for efficient connection and material flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional adapters are manufactured to transition between conduits of different shapes, then the connection between conduits is achieved, but the manufacturing process becomes difficult, costly and time consuming
Solution Approach 1:
The adapter is divided into two separate halves that can be manufactured independently and then assembled together. This segmentation allows each half to be formed from flat metal pieces through bending operations, which are simpler and more cost-effective than manufacturing a complete three-dimensional adapter as a single piece. The divided design also facilitates easier installation and alignment.
Solution Approach 2:
The adapter halves are formed by bending flat two-dimensional metal pieces into three-dimensional shapes that match the required conduit interfaces. This dimensional transformation approach simplifies manufacturing compared to directly forming complex 3D shapes, as it utilizes straightforward bending operations on flat stock material.
2Adaptability or versatility
If adapters are manufactured to connect conduits of different shapes, then shape transition is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
By splitting the adapter into two symmetrical halves, the complex three-dimensional shape transition is achieved through simpler components. Each half contains the necessary geometric features to interface with the respective conduit shapes, and when assembled, they form the complete transition adapter. This reduces manufacturing complexity while maintaining adaptability.
Solution Approach 2:
The adapter halves are designed with asymmetric geometries that match the specific conduit shapes they need to connect. The outer surfaces of each half are shaped to fit one conduit type, while the inner joining surfaces are configured to mate with the corresponding adapter half, creating the shape transition functionality.

AI summary
A material handling system has an input conduit section 12 having an input cross-sectional shape, an output conduit section 14 having an output cross-sectional shape that is different than the input cross-sectional shape, and a transition adaptor 18 connecting the input conduit section 12 and the output conduit section providing a transition between the input and output cross-sectional shapes. The transition adaptor includes a crown piece 20 that has an outer end having an elliptical sectional shape and an inner end. The transition adaptor includes a box piece 30 that has an inner end and an outer end 32 having a rectangular sectional shape, wherein the inner end of the crown piece mates with the inner end of the box piece. The box piece is formed by a first box half and a second box half 42, wherein each box half 40 is formed from a flat piece of metal and is formed by bending the box half 40 about bend lines.
