When it comes to things like dildos and vibrators, though, we need to don the hat of an engineer and get into the nitty-gritty details to give an all-comprehensive explanation of just how self-thrusting sexual dildo toys work.
A vertical piston mounted with thrust bearing and guiding bearing is built in the shaft. In most cases, the thrust bearings sit at the top of the motor. These bearings can be made of spherical roller bearings or angular contact bearings that can be paired with each other. The type and quantity of thrust bearings required for efficient performance and service life are decided on the basis of the upward and downward forces due to the axial load being applied. Yes, for the most part, this is just technical jargon for us non-engineers, but these sex toys really are that technical! However, upon closer inspection, there are a lot of moving pieces that are all working in concert. Apart from two bearings normally synched with each other with a vertical motor, there is also a motor and a set of metal beads inside of a rotating shaft with a HEAD.
The vertical piston and its bearings are an integral part of how the thrusting dildo toy works. It is the thrust bearings that bear the axial forces produced during the thrusting action. This up-and-down action, meant to mimic the natural thrusting that occurs during sexual intercourse, needs those pressures to work properly. The second, guide bearings, ensures that the piston moves smoothly and accurately inside the shaft. They stop all uneven, abrupt motions that could, potentially, disrupt the user’s experience at any point. Combined, these bearings enable a regulated and constant pushing motion to be applied.
These two motors that drive the rotating head and the metal beads add to the complexity and fun! The rotating head may also give a different kind of sensation, perhaps stimulating different areas of the vagina or creating an effect similar to that of whirling. As they spin around inside the shaft, the metal beads can offer a unique texture and feel as the thrusting action is being performed. They also can just feel like something similar to rolling or massage, further elevating the entire sexual experience.
We will have a great sense of admiration for this one-of-a-kind orgasm-inducing technology when we finally understand the complexity of this type of female dildo sexual toy. In footnotes, for a thrusting dildo to function effectively, a high degree of tech needs to have been developed and to be in place. In order to ensure that these toys give the appropriate degree of stimulation and satisfaction, the manufacturers put in plenty of time and effort researching and producing them. Key factors include how comfortable the user feels, the strength and pattern of thumping and rotating actions (if applied), and how long the device will last. Toy-makers are making these things more sophisticated and capable of meeting the varying needs and tastes of users in the pursuit of sexual pleasure and explosive orgasms. This is achieved through constant innovation and evolution.
