Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of taller wooden buildings is hindered by the difficulty in creating large wooden columns that can support the weight, and traditional metal fasteners are not suitable for joining large wooden construction components effectively.
Innovation Solution
A method using bundled tubes formed from multiple wooden pillars of varying lengths, combined with threaded stepped dowels for enhanced structural integrity and connection, allowing for the creation of taller columns and improved joining of wooden components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional metal fasteners are used to join wooden components, then the connection process is simple, but the fasteners are not suitable for joining large wooden construction components effectively and compromise structural integrity
Solution Approach 1:
The patent applies homogeneity by using wood-to-wood fastening components (wooden dowels, wooden connectors) instead of metal fasteners. This ensures material compatibility between the fastening system and the wooden construction components, eliminating the material incompatibility issue that arises when using metal fasteners in wooden structures. The wooden fasteners match the material properties of the surrounding wood, providing better structural integrity while maintaining ease of installation through straightforward insertion and joining processes.
2Strength
If larger wooden columns are created to support taller buildings, then the load-bearing capacity increases, but the manufacturing and assembly difficulty increases significantly
Solution Approach 1:
The patent applies segmentation by dividing large wooden columns into multiple smaller, manageable segments or components that can be manufactured separately and then assembled using the wooden fastening system. Instead of attempting to create and handle monolithic large-diameter wooden columns that are difficult to manufacture and transport, the column is segmented into smaller sections joined together with wooden dowels and connectors, reducing manufacturing complexity while achieving the required load-bearing capacity through the cumulative strength of multiple segments.
Solution Approach 2:
The patent applies composite materials by combining multiple wooden components and fastening elements into a unified structural system. The large wooden column is constructed as a composite assembly of smaller wooden members joined together with wooden dowels, connectors, and adhesives, creating a composite structure that achieves the load-bearing capacity of a solid large column while maintaining the manufacturing advantages of smaller component sizes.
3Ease of manufacture
If platform construction method is used, then each level can be constructed independently, but the weight of higher floors is borne by lower floors causing compression issues
Solution Approach 1:
The patent applies composite materials by using engineered wood products such as cross-laminated timber (CLT) and glued laminated timber (glulam) for the wooden pillars and structural components. These composite wood materials have enhanced compression resistance compared to conventional wood, allowing platform construction to maintain its advantage of independent level construction while the strengthened wooden pillars can support the cumulative loads from upper floors without excessive compression.

AI summary
A system and method for creating a column for construction using bundled tube are provided. The column having a bottom portion, a middle portion, and a top portion. Each portion consists of a bundle of individual pillars, comprising a center pillar, a plurality of corner pillars, and a plurality of middle pillars. From the bottom portion of the column, addition pillars can be affixed on top of the pillars of the bottom portion, thus forming the middle and the top portion of the column. Each pillar can be secured to another component using a thread stepped dowel comprising of a base section, at least one middle section, and a tip section, with each section being progressively smaller in circumference than the last. The at least one middle section of the threaded stepped dowel further comprises thread spiraling around the outer surface of the at least one middle section.
