Treads TRIZ Cases
- S-Shaped Tongue and Groove Flooring Locking Mechanism
Segmented plank edges resolve installation difficulty in confined areas while maintaining joint strength and water tightness.
- Prefabricated Concrete Stair Step with Integrated Reinforcement
One-piece prefabricated concrete stair element eliminates thermal expansion loosening by merging foundation and tread sections into a single reinforced unit.
- Temporary Tread Insert with Bullnose Notch for Stairway Safety
A temporary tread insert uses a notched bullnose shape to engage stair pan contours and provide a slip-resistant walking surface.
- Modular Vinyl Stair Capping System for Open and Curved Designs
A modular vinyl stair capping system uses interlocking channels and bend sections to secure treads and nosings without altering existing structures.
- Ceiling Ladder Deep Step Nesting Design
A folding ceiling ladder incorporates a deep step with increased width for user comfort.
- Modular Precast Concrete Steps Segmentation
Segmented precast concrete steps use internal brackets to maintain structural strength while allowing two-person installation.
- Interlocking Modular Floor Tile with Integrated Connectors
Integrated female connectors on the perimeter receive support legs from adjacent tiles, maintaining alignment and connection strength even after trimming.
- Polygonal Tread Elements with Integrated Connectors
Integrated protruding connectors on polygonal tread elements eliminate separate fasteners, reducing installation time and manufacturing costs.
- Grating Step Reinforcement with L-Shaped Sections
L-shaped sections and orthogonal bands reinforce grating steps, reducing weight while maintaining load-bearing capacity.
- Convertible Stairs with Tiltable Platform for Wheelchair Access
Rotating stairs form a continuous ramp surface on a moving platform, eliminating gaps and misalignment that endanger wheelchair users.
- Asymmetric Textured Wooden Handrail for Grip Safety
Randomly distributed asymmetric relief shapes on a wooden handrail prevent repetitive contact with identical textures, improving user comfort and safety.
