Building Repairs TRIZ Cases
- Vertical Joint System for Uneven Surface Installation
Non-symmetrical vertical joint system with transversely extending surfaces enables relative rotation of engaged substrates.
- Multilayer PVC Floor Coating Resolving Abrasion and Heat Trade-offs
Segmenting the coating into base and top layers resolves the abrasion versus heat resistance contradiction while preventing yellowing.
- Suspended Platform Diagonal Motion for Wall Coating
A suspended platform uses diagonal motion to apply coatings uniformly on external walls.
- Hydraulic Cylinder Cover Flange Design for Debris Protection
A hydraulic cylinder cover uses a segmented flange and arcuate edge to dissipate operational forces while protecting the piston rod.
- Interconnected Trough Deck Drainage System
Interconnected troughs direct rainwater into a gutter via tab-and-channel joints, preventing moisture accumulation under the deck.
- Re-bonding Loose Tiles with Sealed Applicator Chamber
A pliable sealing ring forms a vacuum chamber for precise adhesive delivery to hollow tiles.
- Assistive Support Mechanism for Space Truss Removal
An assistive support mechanism lowers space trusses via a lifting assembly.
- Seam-Mounted Snow Guard for Metal Roof Attachment
A snow guard base with a seam channel and moveable fastener clamps the metal roof seam securely.
- Wall Reinforcement Bracket and Adhesive Strap System
A wall reinforcement system couples structural elements to support members using a bracket and adhesive strap.
- Benchmark Marking Tool Segmentation for Nuclear Water Tightness
A benchmark marking tool uses a segmented stainless steel plate and carbon steel stud to maintain precise reference positions during construction.
- Tower Shuttle for Mobile Stage Assembly
A caster-mounted tower shuttle positions structural towers on mobile stages using ball-and-socket joints.
- Crack Restoration via Curved Injection and Slope Monitoring
Injection stops when the detection curve shows an abrupt slope reduction, neutralizing parasitic stresses while ensuring complete crack closure.
- Mesoporous Silica Gel for Stone Strengthening
Uniform mesopores reduce capillary pressure to prevent fractures while maintaining steam permeability.
- Muntin Bar Joiner Clip With Stress Riser for Configurable Patterns
A muntin bar joiner clip features a weakened stress riser region that allows the component to be broken into separate pieces by hand flexing.
- Modular Building Lock Mechanism for Rigid Frame Connection
Segmented lock mechanisms join structural frames with tension screws, eliminating wear from threaded engagement while maintaining rigidity.
- Garage Door Window Frame Rib-Groove Impact Absorption
Front and rear frame members sandwich a transparent pane using an integrated rib and groove locking mechanism.
- Gapped Inclined Brace Seismic Retrofit
A gapped inclined brace system transmits axial forces only during significant column deformation to enhance structural support.
- Multifunctional Demolition Tool Tine Leverage Design
A prying head with tapered tines and a cylindrical cross frame provides mechanical leverage for demolition tasks.
- Drywall Repair Plug with Tensioner and Plank
Tensioner guides frustoconical plug into drywall hole while anchoring elongated plank, eliminating multiple mud applications.
