Roofs TRIZ Cases

Nested panel segments resolve the contradiction between secure storage and maximum opening degree in convertible tops.

A tension rod stiffens the convertible top by resisting downward forces on the four-bar linkage, solving rigidity issues in lightweight designs.

Fabric deflection levers guide convertible top covers during displacement, preventing crumpling and ensuring precise folding in storage.

Repositioning the support frame below the top eliminates vertical lifting effort during loading.

A sunroof apparatus uses a panel support stay to enlarge the movable roof panel support span.

Segmented latches with flexible seals resolve water infiltration while maintaining rear window visibility.

A side panel with a curved pivot mounting reduces vertical space requirements.

A sunshade positioning member incorporates a recess for inwardly folded wings to reduce entrance opening size.

Segmented ratchet locking prevents unintentional unwinding while simplifying manual operation.

A detachable vehicle roof system uses a contoured front support bar and buffer zone to isolate structural components from chassis vibrations.

A single drive motor operates moon roof and roller shade via a selective transmission, reducing overhead space and part costs.

An extendable deflector assembly diffuses incoming air to lower wind noise and aerodynamic drag.

Gas struts offset soft top weight while a cam lockout prevents rotation back to the sunroof position, resolving fabric entanglement.

A sunroof shoe member uses a limiting protrusion to engage the guide rail and support the movable panel.
