Building Support Scaffolds TRIZ Cases
- Hanging Scaffold Chain Coupling for Easier High-Load Attachment
A stopper-and-cylinder chain coupling simplifies scaffold attachment, raises load capacity, and can reduce the number of chains needed.
- Foldable Elevator Hoistway Work Stage for Fast Safe Deployment
A foldable hoistway stage uses a backspan, lift mechanism, and extensible brace to cut setup time while improving worker safety.
- Wall-Mountable Perch With Tension Arms for Scaffold-Free Window Work
Flexible support and tension arms secure a stable platform through a window opening without wall penetration, reducing scaffolding time, cost, and permits.
- Ridge-Hook Cable Roof Scaffolding for Damage-Free Sloped Roofs
Nodular cables secured by ridge hooks support workers and materials on sloped roofs without nails or damage to roofing materials.
- Ladder Step Prevention Device with Angled Side Flaps
A solid front face and angled side flaps prevent stepping on the first step without bulky attachments.
- Ladder-Mounted Roof Support Platform for Firefighter Stability
Removable ladder platform provides stable footholds, resolving the contradiction between access speed and footing reliability.
- Remote Controlled Overhead Ladder Motorized Folding Mechanism
A motorized drive apparatus with a lifting cable pivots sectional ladder components for automated storage.
- Steep Roof Scaffold with Ridge Hooks and Locking Casters
Locking casters on parallel rails enable lateral movement along steep roofs, resolving the trade-off between repositioning time and platform stability.
- Stepladder with Integrated Conduit Holder and Wire Spool Management
Integrated conduit holders and wire spool mounts resolve the trade-off between ladder simplicity and electrician workflow efficiency.
- Modular Scaffold Ladder with Adjustable Walkway and Support Legs
Telescopic walkways and pivotally coupled ladders eliminate assembly time by allowing rapid repositioning on uneven surfaces.
- Height Reducible Enclosure Platform With Torsion Bar Locking
Spring assisted mechanical folding mechanism replaces hydraulic systems to enable single person operation without increasing shelter complexity.
- Liftable Scaffold Pinion Mechanism for Height Adjustment
Hydraulic motor drives a toothed pinion with rollers to lift the scaffold platform, preventing falls via safety dogs during height adjustment.
- Retractable Ladder Side-Mounted Pivot Mechanism
Side-mounted brackets pivot ladder arms vertically, removing roof load and preventing structural compromise.
- Roofing Ladder Bracket with Integrated Safety Attachment
A rigid bracket secures ladders to roofs while providing attachment points for worker safety gear.
- Weight-releasing ladder lockstep with pivoting shock links
A weight-releasing ladder lockstep uses compression springs and pivoting shock links to retract front wheels upon user weight.
- Modular Roofing Ladder with Angularly Adjustable Platform
Beam lifters separate the ladder from the roof surface during work, eliminating direct contact while maintaining stability and access.
- Ladder Accessory with Rail Channels for Pitched Roof Footing
Segmented platform extends perpendicular to ladder rails to deliver stable footing, reducing fall risk during vertical ventilation on pitched roofs.
