Building Roofs TRIZ Cases

Radial projections on slat shafts engage beam fittings to prevent structural bending without adding material cost.

Automated sliding power lift system replaces manual effort with motor-driven drive blocks and latch dogs to secure boat hatches.

Nail-fastened purlins and integrated starter-terminator simplify roofing assembly.

Stability members with stabilizing arms engage surface tile corners to restrict lateral and vertical movement between adjacent elevated deck components.

V-grooves in lightweight concrete enable moisture venting while adhesive mortar eliminates mechanical fastener damage.

Multi-stage design accounts for nonlinear deformations, ensuring structural safety and reliability.

A motor-driven wheel translates a fixing element while a rotatable housing pivots to minimize bulk.

Continuous unidirectional rotation via a rocker arm eliminates reverse motion, preventing component interference and collision damage during closure.

Segmented tubular corner blocks with coplanar faces and adjustable spacers maintain precise trim cover alignment across varying panel heights.

V-shaped grooves in rigid layers enable a flexible covering to adapt to complex curved surfaces, reducing manufacturing time and installation costs.

Metal rafter bracket connects posts to beams using vertical side plates and a horizontal plate.

Modular floor beams feature locking mechanisms that enable rapid assembly of grid structures for temporary applications.

Segmented dwelling members housed in a transportable main frame resolve the contradiction between movability and extensibility for prefabricated housing.

Annular beads on coaxial tubular sections guide accurate cutting, preserving sufficient axial length for hose clamps and preventing seal damage.

A cantilevered deck system uses a moment-resisting frame to support the structure without columns.

Resilient fastener portions telescope into passageways while a nested locking member secures elements for adjustable orientations.

Segmented gongpo parts with interlocking slots reduce construction time and labor costs while preserving decorative quality in hanok buildings.

Square timber pieces connect via wooden plugs to form modular structures, overcoming wood anisotropy and enabling flexible plan modifications.

Segmented anchor assembly provides secure mounting on piers while enabling rapid disassembly for seasonal storage.
