Tapered Interface for Structural Column Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in building construction is the time-consuming and costly process of welding column segments together at the construction site, especially when transporting full-length columns is difficult for taller buildings, leading to inefficiencies in erecting multistory frames.
Innovation Solution
A tapered interface system for column segments, where a female end section with a transversely outwardly tapering interior surface and a male end section with a complementary transversely inwardly tapering exterior surface allow for mechanical coupling without welding, facilitated by fasteners, enabling efficient alignment and assembly of column segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If column segments are welded together at the building site, then structural integrity is achieved, but assembly time and cost increase significantly
Solution Approach 1:
The patent replaces the welding process (thermal/chemical joining method) with a mechanical connection system consisting of a tapered interface between column segments. The tapered male end section inserts into the tapered female end section, creating a mechanical interlock that eliminates the need for welding while maintaining structural integrity through friction and geometric constraint.
Solution Approach 2:
The patent changes the joining method from permanent welding to reversible mechanical connection. The tapered interface geometry allows for easy insertion and removal, transforming the assembly process from a time-consuming welding operation to a quick mechanical coupling operation, thereby reducing assembly time and cost.
2Productivity
If full-length columns are transported to the building site, then construction efficiency improves, but transportation difficulty increases for taller buildings
Solution Approach 1:
The patent divides full-length columns into multiple transportable segments that can be easily transported to the building site. Each segment includes end sections with tapered interfaces that allow for quick mechanical assembly, transforming the single full-length column into multiple manageable pieces that can be transported separately and assembled efficiently on-site.
3Ease of operation
If column segments are divided for transportation, then transportation ease improves, but assembly complexity increases
Solution Approach 1:
The patent employs asymmetric tapered interfaces where the male end section has a taper that complements the female end section's taper. This asymmetric geometry provides self-aligning properties during assembly, guiding the segments into correct orientation and reducing assembly complexity despite the segmented design. The tapered shapes naturally guide alignment, eliminating the need for complex alignment procedures.

AI summary
An interface for a structural column includes a female end section that includes at least one first sidewall that extends from a first end along a longitudinal direction and defines a first cavity. An interior surface of the at least one first sidewall tapers transversely outwardly along the female end section towards the first end. The interface also includes a male end section that includes at least one second sidewall that extends from a second end along the longitudinal direction and defines a second cavity. The at least one second sidewall is configured to be received within, and oriented in substantially face-to-face adjacent relationship with, the at least one first sidewall. An exterior surface of the at least one second sidewall tapers transversely inwardly, complementary to the at least one first sidewall, along the male end section towards the second end.
