Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing furcated steel posts are costly, inefficient, and limit the incorporation of anti-corrosion coatings, post-cutting, and hole-punching operations, while requiring tapered arms and restricting the use of different steel grades.
Innovation Solution
A method involving cold profile rolling of steel strips to form composite posts with welded arms, allowing for anti-corrosion treatments, post-cutting, and hole-punching before or after rolling, using various steel grades and profiles, and incorporating fencing wire retainers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional steel post manufacturing processes are used, then high production rates can be achieved, but the cost becomes high and small quantities cannot be produced cost-effectively
Solution Approach 1:
The post is divided into multiple strips that are joined together along their length in a furcated manner. These strips can be manufactured separately and then assembled, allowing flexible production quantities and reducing tooling costs for small batches while maintaining efficiency for large quantities.
Solution Approach 2:
The post is constructed as a composite structure from multiple steel strips of potentially different grades joined together. This allows optimization of material usage and cost while maintaining structural integrity, and enables small quantity production to be cost-effective by using standard steel strip products.
2Ease of manufacture
If anti-corrosion coating is applied after post manufacturing, then the coating application is possible, but the process becomes more complex and time-consuming
Solution Approach 1:
Anti-corrosion coating is applied to the individual strips before they are joined together to form the complete post. This preliminary coating action simplifies the overall manufacturing process by eliminating the need for complex post-assembly coating operations and allowing each strip to be coated using standard, simple processes.
3Ease of manufacture
If post-cutting and hole-punching are performed after post manufacturing, then the operations are possible, but the process becomes less efficient
Solution Approach 1:
Cutting and hole-punching operations are performed on the individual strips before they are joined together to form the complete post. This preliminary processing of strips improves manufacturing efficiency by allowing these operations to be performed on smaller, more manageable pieces using simpler, faster equipment rather than attempting to cut and punch the completed assembled post.
4Ease of manufacture
If steel strips are tapered in the manufacturing process, then the manufacturing is simpler, but the arms cannot be non-tapered at their free ends
Solution Approach 1:
The post is segmented into multiple strips that are joined together. This segmentation allows the free ends of the arms to remain non-tapered (straight) while the joining structure accommodates any necessary tapering in the main body, providing design flexibility without complicating the manufacturing of individual strip components.
5Ease of manufacture
If a single grade of steel is used throughout the post, then the manufacturing is simpler, but different grades of steel cannot be incorporated
Solution Approach 1:
The post is constructed as a composite structure from multiple steel strips that can be of different grades. This composite approach enables the incorporation of different steel grades in different regions of the post to optimize performance and cost, while each individual strip can still be manufactured using simple, standard processes for that specific grade.

AI summary
A method of manufacturing a furcated composite post (1) comprising at least two strips (7, 8) that are joined together along their length in a furcated manner. The method comprises the steps of feeding one or more of the strips (7, 8) at a set rate to working rolls of a roll mill for profile rolling to a desired cross section/profile, feeding the strips (7, 8) at the same set rate to positioning rolls for holding the strips (7, 8) in a correct orientation for joining, and joining the strips together, preferably by welding the strips (7, 8) along their length.
