"Traditional clips are single-piece plastic parts designed for one-time installation. Over time, they loosen, rattle, and transmit road noise, suspension vibrations, and minor panel buzz directly into the passenger compartment. Tesla's new design turns that ordinary item into a reusable, two-material vibration-damping system built for long-term silence."
"The clip consists of four components drawn from just two material families. The pin and grommet are molded from rigid glass-fiber-reinforced nylon, giving them the strength needed to hold panels firmly in place. Not a Tesla App reported on the patent."
"A soft thermoplastic elastomer (TPE) is then overmolded onto the assembly in a distinctive mushroom shape that flares outward beyond the pin shaft. This soft layer does the heavy lifting for comfort: it spreads mechanical loads over a wider area and actively damps oscillations before they can reach the interior trim."
A vehicle interior trim clip secures panels to the body structure. Conventional single-piece plastic clips loosen over time, rattle, and transmit road noise, suspension vibrations, and panel buzz into the passenger compartment. A new design makes the clip reusable across multiple service cycles. The clip uses two material families: rigid glass-fiber-reinforced nylon for a pin and grommet to provide strength and stable panel retention. A soft thermoplastic elastomer is overmolded onto the assembly in a mushroom shape that flares outward beyond the pin shaft. The elastomer spreads mechanical loads over a wider area and actively damps oscillations before they reach the interior trim, reducing noise and vibration.
