Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beams for cantilevered structures are not versatile, difficult to adjust, and poorly handle torsion and thermal stresses, leading to instability and durability issues in building construction.
Innovation Solution
A beam with elongated, tubular structure and adjustable attachment bars and nuts, allowing precise positioning and torsion resistance, filled with reinforcing material, and featuring thermal breaks for improved stability and thermal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a specific beam is designed for a specific cantilevered structure, then the connection is simplified, but the versatility of the beam is reduced
Solution Approach 1:
The beam is designed with a universal attachment system featuring multiple holes arranged in different patterns (first pattern for metal structures, second pattern for concrete structures) and adjustable attachment means that can be positioned at various locations along the beam. This allows a single beam design to accommodate multiple types of cantilevered structures (metal structural work, reinforced concrete, prefabricated elements) while maintaining simple connection procedures for each type.
2Ease of manufacture
If the beam design is fixed, then the manufacturing is simplified, but the adjustment capability of the cantilevered structure position is reduced
Solution Approach 1:
The beam incorporates adjustable attachment means (such as bolts or screws) that can be positioned at multiple locations along the beam's length, combined with holes arranged in specific patterns. This allows the attachment position to be dynamically adjusted along the beam while maintaining a fixed, simple beam structure. The adjustment capability enables precise positioning of cantilevered structures relative to the building facade without requiring complex or variable beam designs.
3Strength
If traditional beams are used for cantilevered structures, then the structural function is provided, but the resistance to torsion stresses is insufficient
Solution Approach 1:
The beam employs a composite steel-concrete construction where a steel I-beam provides the primary structural framework and is partially or fully surrounded by concrete. This composite design leverages the high tensile strength of steel and the compressive strength of concrete, creating a structure with superior resistance to torsion stresses compared to traditional single-material beams, while maintaining the necessary structural function for supporting cantilevered structures.
4Ease of manufacture
If the beam directly connects to the building structure, then the connection is simplified, but the thermal stress durability is reduced
Solution Approach 1:
The beam incorporates thermal break elements (such as plastic or wooden blocks) positioned between the steel beam and the building structure at attachment points. These intermediary elements prevent direct thermal contact, blocking heat transfer pathways that would otherwise create thermal stresses in the building's finishes, plasters, and masonry infills. The thermal breaks maintain connection simplicity while significantly improving thermal durability.
