The Unique MySpot 500/510
Design challenges and Solutions
The MySpot 500 and the MySpot 510 share a mechanical platform. These are advanced products made to look simple and elegant from the outside. This page provides a look inside.
The design challenges we faced included keeping a low profile for the housing, to allow even low-slung cars to drive over the unit when it is in the "un-obstruct" mode. Our research found that 99% of the cars on the road have a road clearance of just below 4" (90 mm). The MySpot 510 (and MySpot 500) lowered height is only 3" (76mm).
Another goal was to allow 10,000 up/down cycles on 5 standard D alkaline batteries. None of the competing products on the market come even close. A review showed that they all use worm gears to drive the barriers up and down. Worm gears have high friction losses and are less than 30% efficient. Replacing the worm gear with a direct drive made our unit at least 3 times as efficient, meaning that the battery can last that much much longer. More details are available in our issued US patent 9,464,392.
