Patent No. US11925592 (titled "Penis Massager") was filed by Wu Junpeng on May 29, 2023.
’592 is related to the field of massage devices, specifically penis massagers. These devices aim to simulate a vaginal environment, providing stimulation to the user. Existing designs can be difficult to hold due to vibration and size limitations imposed by the internal sleeve.
The underlying idea behind ’592 is to improve the ergonomics and usability of a penis massager by adding external handles . These handles allow the user to maintain a secure grip, even with strong vibrations, without being constrained by the size of the internal sleeve.
The claims of ’592 focus on a penis massager comprising a housing, a sleeve within the housing defining a cavity for penis insertion, a driving device to move the sleeve, and at least two handles extending outward from the housing . Claim 1 specifies the handles are located at the end of the housing away from the sleeve opening and include buttons. Claims 14 and 15 specify that the handles are slidably or rotatably connected to the housing.
In practice, the invention incorporates a vibrating sleeve inside a housing. A motor drives the sleeve to vibrate, rotate, or reciprocate, providing stimulation. The key addition is the two or more handles on the outside of the housing. These handles are designed to be easily gripped, allowing the user to maintain control of the device even during intense vibration. Some embodiments include buttons on the handles to control the motor.
The differentiation from prior approaches lies in the addition of the handles. Previous designs relied on gripping the housing itself, which could be difficult due to the size constraints imposed by the internal sleeve and the vibrations generated by the motor. By providing dedicated handles, the user has a more secure and comfortable grip, and the design of the sleeve and housing can be optimized for performance rather than grip.
In the early 2020s when ’592 was filed, at a time when personal care devices were typically implemented using embedded microcontrollers for controlling motors and user interfaces. When systems commonly relied on rechargeable batteries rather than wired power sources for portability. When hardware or software constraints made precise motion control and ergonomic designs non-trivial.
The examiner allowed the claims because the prior art of record does not teach or reasonably suggest the specific configuration of handles in combination with a penis massager, nor does it teach or suggest handles connected in the recited manners in combination with such a device.
The patent has 17 claims, with independent claims 1, 14, and 15. The independent claims are directed to a penis massager comprising a housing, a sleeve, a driving device, and handles. The dependent claims generally elaborate on specific features and configurations of the penis massager described in the independent claims, such as the shape and connection of the handles, the driving device components, and the sleeve's interior surface.
