Matching center holes and spring pins let modular truss beams align and lock quickly without tools, improving reuse and portability.

Pre-formed metal sheets are welded into a box beam with non-radiused corners, enabling flexible cross sections, lower weight, and strong impact resistance.

Preformed metal sheets welded into tubular bumper beams enable varied cross-sections, lower weight, and stronger impact performance with less tooling.

A slit locking clamp stabilizes extendible slit-tube masts by resisting edge shear, improving stiffness and safer deployment under heavier loads.

Locking the slit edges at intervals prevents local shear in deployable tube masts, increasing stiffness for longer spans and heavier loads.

A web-and-flange blocking structure with stud-mounting ears improves installation tolerance and load capacity beyond flat straps or C-channels.

Localized continuous-fiber layers in a chopped-fiber plastic body improve tensile load and impact resistance without the weight of metal.

A folded and flattened tubular end creates four material layers, boosting strut connection bending stiffness without inserts or costly forming.

A folded, flattened tubular end creates four material layers that raise strut connection stiffness without added inserts or costly forming.
