Building Repairs TRIZ Cases

A portable modular lifting stand raises transmission towers using hydraulic mechanisms and outriggers to install vertical extension sections.

Coupling caps compress the elastic tube to prevent repair liquid leakage during high-pressure grouting of concrete cracks.

Removing half-landing stairwells allows prefabricated shafts to install, resolving construction disruption while achieving universal floor access.

Segmented brackets bolt into a clamping ring that reinforces corroded poles, eliminating the need for skilled welders and reducing repair complexity.

Concrete anchor blocks and U-shaped tie rods automatically level wall posts, eliminating manual balancing during installation.

Projection-based anchorage absorbs tensile loads without drilling into the steel core, preserving structural integrity.

Epoxy resin cladding and polymer concrete layers prevent premature debonding of prestressed FRP bars by ensuring uniform stress transfer.

A composite window frame combines metal structural members with non-metallic thermal breaks to reduce heat transfer across the building envelope.

Multi-stage resin injection corrects uneven ground subsidence while maintaining strict process control.

Segmented steel cap design bridges new foundations and existing towers, extending service life without increasing structural complexity.

A motorized lifting apparatus uses a wedge mechanism to extract carpet tiles from adhesive floors.

Counterforce generators stabilize suspended cleaning frames against wind displacement while soft brushes remove dirt without scratching coated glass.

A grounded conductive cover dissipates static charge from an insulation hose, preventing moisture damage and ensuring uniform density without water.

A rolling block restraint connector uses a two-rod linkage to form rigid moment connections between structural members.

Autonomous biological agents vascularize deep concrete defects to prevent corrosion and restore strength without toxic chemical inhibitors.

Segmented gypsum plug with spiral recesses absorbs fluid to fasten in plasterboard holes, eliminating multi-layer joint compound drying time.

Segmented diameters in a wood fiber plug enable easy insertion through thick thermal walls while preventing visible markings and thermal bridges.

Post-tensioned strands within a timber module anchor to beams, resolving the trade-off between structural rigidity and fire resistance.

Templates segment FRP application zones around a filler module, resolving stress concentration and delamination risks at structural joints.

A floor hole repair fixture uses a depending rim and intumescent coating to seal concrete deck voids.

A pre-fabricated composite reinforcement device secures metal and fiber reinforced polymer layers to structures using power-actuated fasteners.

A carpet cutting apparatus uses wheels and a strand guard to maintain optimal cutting angles.

Acoustic sensors measure sound transmission through insulation to determine density without destructive testing or repair time.

An acute-angle deformation zone in a carbon fiber profile allows complex shaping while preventing fiber stress, reducing production costs and corrosion risks.
