Roofs TRIZ Cases
- Tonneau Cover Tie-Down Assembly With Redundant Tether Backup
A dual tie-down block and tether backup keeps a truck bed tonneau cover secured even if the primary attachment fails.
- Vehicle Open Roof Slide Shoe Retention in Crash Conditions
An enlarged pin head overlaps guide parts to keep the slide shoe engaged during crashes, preserving roof panel positioning and movement.
- Tonneau Cover Clamp Support With Shims for Variable Flange Spacing
Thickness-matched shims fill variable cargo-box flange gaps, while a clamp support limits rotation and keeps the tonneau rail securely attached.
- Wind Deflector Assembly With Single-Leg Biasing Against False Anti-Trap
A single-leg biasing layout keeps the vehicle roof wind deflector taut at high speed while reducing false anti-trap events and noise.
- Modular Centre Guide Rail Layout for Universal Open-Roof Assemblies
A central cable channel between parallel guide channels lets one open-roof rail fit front- or rear-drive layouts with less redesign and processing.
- Vehicle Canopy Three-Panel Join With Offset Sealing Lips
Offset, overlapping lip joints create a flush three-panel canopy seal that blocks water and dust without post-assembly sealant.
- Tonneau Cover Panel With Stowable Table for Cargo and Workspace
A table nested inside the tonneau cover cavity stiffens the panel for top cargo and unfolds into a ground-standing workspace.
- Vehicle Cover Articulation Mechanism With Segmented Sliding Trolley
A segmented trolley and hinge layout simplifies trailer cover assembly while preserving rigidity, load transfer, and smooth folding.
- Hybrid Roof Crossmember Layout for Larger Vehicle Roof Openings
A hybrid roof crossmember merges body and module shells to free roof space, enlarge the viewing opening, and house drive components.
- Vehicle Wind Deflector Assembly With Low-Force Taut Mesh
Bending-spring tensioning keeps the wind deflector mesh taut in multiple active positions without raising operating force or disturbing movement.
- Soft Front Cockpit Cover Linkage for Quick Open-Air Roof Access
A linked soft front cockpit cover folds back from a sealed hard-top roof to give quick open-air access without bulky panel removal or storage issues.
- Pickup Tonneau Cover Extension Panel for Tailgate-Clear Support
A hinged extension panel adds up to 300 mm of truck bed cover length while preserving cargo access and avoiding tailgate interference.
- Commercial Vehicle Sliding Roof With Spring-Assisted Lifting Arms
Prestressed spring ends raise paired lifting arms during opening, cutting sliding roof actuating force and simplifying cargo cover construction.
- Retractable Vehicle Sunshade With Independent Front-Rear Control
Clamped support beams let front and rear occupants extend, retract, and lock sunshade panels while driving without stopping.
- Convertible Soft Top Tensioning With Integrated Cable Winding
A gearbox-integrated winding unit varies traction cable length to keep the convertible soft top cover taut without excessive loads or complex tensioning.
- Lift-Assisted Pivotal Soft Top for Easier SUV Roof Opening
An internal strut in the front rail helps rotate a pivotal soft top, reducing manual effort and improving fabric handling during opening and closing.
