Escalators TRIZ Cases
- Escalator Floor Cover Coupling Element Resilient Return
Resilient return sections in the coupling element generate restoring force to prevent unintentional lifting of escalator floor covers caused by shoe entrapment.
- Escalator Handrail Tension Monitoring via Imaging Sensors
Imaging sensors analyze handrail tension features against preset intervals to prevent over-tension abrasion and under-tension safety hazards in escalators.
- Escalator Structural Frame for Elevator Integration
Fastening points on the escalator frame support an attachable elevator platform, resolving wheelchair accessibility without disrupting transport flow.
- Escalator Step Crossbeams with Bulbous Profile
Variable-height crossbeams deliver uniform stress distribution to resolve the trade-off between structural stability and material weight in escalator steps.
- Escalator Steps with Angled Side Flanges for Entrapment Prevention
Angled side flanges on escalator steps form continuous barriers to prevent object entrapment between moving components and stationary panels.
- Treadmill Rear Guard Comb Mechanism for Debris Deflection
Segmented interlaced comb guard prevents debris entry into treadmill rear area, enhancing safety and reducing maintenance needs.
- Passenger Conveyor Step Anti-Jump Member Design
An integrated support structure merges emergency tracks with step guides, eliminating separate components and reducing installation complexity.
- Escalator Tread Element Cantilever Arm Design
Pivotable riser panels and cantilever arms reduce turnaround bending radius while maintaining narrow safety gaps.
- Escalator Step Tread Element Fixing via Interference Fit
Rigid fixing elements eliminate elastic layers to prevent vibration noise and simplify assembly in escalator steps.
- Escalator Pit Cover Safety via Detector Feedback
An escalator system uses a pit detector to monitor access cover position and control movement.
- Driving Pulley for Flexible Handrail with Liquid-Filled Tire
Liquid filling in the driving pulley prevents bulge formation and slip-stick noise while maintaining continuous contact drive.
- Escalator Combplate Tooth Detection via Ultrasonic Signal Analysis
Automated acoustic detection replaces manual inspection to monitor tooth integrity, preventing escalator shutdowns caused by mispositioned components.
- Escalator Step with Dual-Radius Seating Element
Dual-radius sheet metal geometry ensures a uniform step gap during inclined-to-horizontal transitions, preventing finger entrapment hazards.
- Truss Reinforcement Device for Escalator Braking Retrofit
A truss reinforcement device absorbs braking forces via rotatable shaft supports.
- Escalator Unattended Child Detection and Safety Intervention
Evaluation unit compares sensor signals against detection profiles to trigger warnings or stop the escalator, preventing child injury.
- Belt-Driven People Conveyor with Flexible Toothed Drive Belt
Replacing chain links with a direct belt engagement system reduces wear-induced elongation and noise while minimizing the conveyor footprint.
