Building Repairs TRIZ Cases
- Seismic Precast Concrete Blocks with Internal Bars for Axial Resistance
Interlocking PC blocks use internal bars and filler to resist axial loads without fireproof coating.
- In-Frame Dissipation Devices for Seismic Retrofit of Existing Frames
This case uses a concrete-filled rigid body inside frame apertures to dissipate seismic energy without external enlargement.
- Extendable Needle Davit Assembly with Fixed Beam and Telescopic Reach
This davit assembly separates fixed structural support from telescopic adjustment for modular, secure rope access on lightweight surfaces.
- Demolition Machine Layout for Balanced Lifting and Confined-Space Maneuvering
This case shows how engine, reservoirs, counterweights, and a central boom support improve lifting balance and controlled movement.
- Protruding FRP Panels for Underwater Corrosion Repair
Pre-manufactured FRP panels with protruding profiles simplify underwater repairs and form a durable grout-filled reinforcement layer.
- Self-Supporting Equipped Wall Structure for Seismic Partition Stability
Elastomeric pads, adjustable connections, and modular framing stabilize partition walls while shielding occupants from falling debris.
- Carpet Cutter With Slanted Blade and Winch-Pulled Strip Removal
A foot-supported cutter, cable, clamps, and winch automate carpet strip cutting and pulling, reducing manual removal effort.
- Structural Connector With Dual Tension Rods for Sagging Floors
An adjustable connector tensions adjacent joists with dual rods, lifting sagging floors and reducing deflection, bounce, and squeaks.
- Civil Structure Reinforcement Using High-Grammage Fabric and Staged Resin
This case uses larger, then smaller resin particles to fully impregnate heavy woven fabric for civil structure reinforcement.
- Marine Concrete Crack-Healing Agent for Corrosive Ion Binding
A composite core, PMMA wall, and cement layer help seal cracks and bind chloride, sulfate, and magnesium ions in seawater.
