Roofs TRIZ Cases

A pushrod and lift-ramp lock lets one person install and secure a retractable pickup bed cover with compact panel stacking.

A shared lateral layout for lifting and guiding devices keeps roof panel tracks aligned, enabling smooth transfer and a narrower rear support.

Flexible hinges and magnetic securing members let rigid tonneau panels fold upright securely while simplifying removal and cargo access.

Connection channels route water from the sunroof groove into the vehicle drainage path, preventing cabin ingress even on inclined vehicles.

A second interior rib deflects and spreads airflow before it reaches the cabin, reducing wind drop while preserving roof appearance over time.

Equal-width intermediate bars simplify hard folding car cover assembly, cut tooling and transport costs, and ease locking maintenance.

Integrated cam and support grooves in the sunroof frame cut parts, simplify assembly, and maintain stable deflector blade movement.

A ribbed stiffener and rail attachment create cover tension, improve lateral holding strength, and shed water on a rolling truck bed cover.

An omega-profile one-piece roof bow integrates attachment sections and rollers to cut trailer body assembly work while keeping high load capacity.

A triangular folded stack and bulkhead placement assembly keep a truck bed cover stable upright while clearing the center stop lamp.
