Interlocking Profiled Beam Assembly for Lightweight Cellular Structures

The patent employs composite material construction by combining a core material (such as foam, honeycomb structure, or lightweight polymer) with flange materials (such as aluminum, steel, or fiber-reinforced composites) that have high strength-to-weight ratios. This composite approach achieves the required structural integrity while significantly reducing the overall weight compared to traditional solid metal beams, directly resolving the contradiction between strength and weight.

The patent utilizes composite materials including polymers, plastics, or fiber-reinforced composites for the core and flanges, which are generally less expensive than traditional metal construction. These materials can be manufactured through cost-effective processes such as molding or extrusion, reducing both material and manufacturing costs while maintaining structural integrity through optimized composite design.

The patent replaces traditional mechanical fastening systems (bolts, welds) with an integrated monolithic or pre-assembled structure where the flanges and core form a unified beam element. This substitution eliminates the need for secondary fastening operations, reducing assembly complexity and manufacturing steps while maintaining structural integrity through the inherent design of the composite beam itself.

The patent eliminates time-consuming fastening operations by designing the profiled beam elements as integrated units where the core and flanges are already bonded or formed as a single piece. This substitution of the fastening system with an integrated design allows for rapid installation through simple placement and connection, dramatically reducing assembly time while preserving structural integrity through the engineered composite construction.
