In an example, a lacing engine apparatus can include a housing and a drivetrain. The housing can be securable within a footwear article. The drivetrain can include a motor, a sun gear, a planet gear,a rotating ring gear, and a spool. The spool can be secured to the ring gear and can be rotatable therewith. The spool can be configured to control a lace of the footwear article and can be configuredto wind the lace as the ring gear rotates in a first direction. 在一示例中，系鞋带引擎设备可以包括壳体和传动系。该壳体可以固定在鞋物品内。传动系可以包括马达、太阳轮、行星齿轮、旋转齿圈和线轴。线轴可以固定到齿圈并且可以随其旋转。线轴可以配置为控制鞋物品的鞋带，并且可以配置为随着齿圈沿第一方向旋转而缠绕鞋带。
