Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single motor driving the massage head to do linear reciprocating motion is used, then the device structure is simple, but the stimulation range is limited and stimulation effect is unsatisfactory
Solution Approach 1:
The patent divides the driving system into two independent driving units: a first driving unit (vibration motor) and a second driving unit (gearbox with swing arm). This segmentation allows each unit to perform a specific motion function, collectively achieving multi-dimensional stimulation while maintaining reasonable structural complexity
Solution Approach 2:
The patent transitions from one-dimensional linear reciprocating motion to two-dimensional annular trajectory motion by introducing the swing arm mechanism. The massage portion moves along an annular trajectory in addition to vibration, expanding the stimulation range and creating a kneading effect that covers a larger area of the rectum or vaginal wall
2Device complexity
If a single motor driving the massage head to do linear reciprocating motion is used, then the device structure is simple, but the stimulation effect is unsatisfactory
Solution Approach 1:
The patent segments the stimulation function into two distinct mechanisms: vibration from the first driving unit and annular kneading motion from the second driving unit. This segmentation ensures that each mechanism can be optimized for its specific function, thereby improving overall stimulation effectiveness without excessive complexity
Solution Approach 2:
The patent merges two different types of motion (vibration and annular reciprocating motion) into a single integrated device. The combination of these motions creates a comprehensive stimulation effect that addresses multiple aspects of sexual stimulation, thereby improving reliability of the stimulation effect
3Area of stationary object
If the massage portion moves along an annular trajectory to knead the vagina or rectum, then the stimulation area is enlarged and stimulation effect is improved, but the device complexity increases
Solution Approach 1:
The patent employs dynamic mechanisms including a vibration motor for vibrational motion and a swing arm with gearbox for annular reciprocating motion. These dynamic components enable the massage portion to move along an annular trajectory, enlarging the stimulation area while maintaining manageable device complexity through efficient mechanical design
Solution Approach 2:
The swing arm acts as an intermediary mechanism that converts the rotational motion from the gearbox into annular reciprocating motion of the massage portion. This intermediary mechanism enables complex motion patterns without requiring direct complex actuation, thereby balancing stimulation area enlargement with acceptable device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a more comfortable and effective sexual experience by enlarging the stimulation area and improving the stimulation effect, making it more likely for users to reach orgasm.
Implementation Method 1
a first driving unit including a vibration motor arranged in the massage portion
Implementation Method 2
a second driving unit including a gearbox and a swing arm driven by the gearbox, one end of the swing arm being connected to the massage portion, under the driving of the second driving unit, the massage portion moving along an annular trajectory to make the massage surface form a kneading effect on the rectum wall or the vaginal wall

AI summary
A sexual stimulation device includes a shell, a first driving unit and a second driving unit. The shell includes a massage portion formed at one end thereof, wherein the massage portion is configured to be inserted into a rectum or a vagina of a human body. An outer surface of the massage portion serves as a massage surface of the sexual stimulation device for contacting a rectum wall or a vaginal wall. The first driving unit includes a vibration motor arranged in the massage portion; and the second driving unit includes a gearbox and a swing arm driven by the gearbox. One end of the swing arm is connected to the massage portion, and under the driving of the second driving unit, the massage portion moves along an annular trajectory to make the massage surface form a kneading effect on the rectum wall or the vaginal wall.
