Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional vibration apparatus with motor and eccentric block is installed, then vibration function is achieved, but the size increases and compactness is lost
Solution Approach 1:
The patent combines the motor, eccentric block, and vibration transmission mechanism into a single integrated vibration apparatus that fits within the cup structure. The motor is positioned at the bottom of the cup with the eccentric block mounted on its output shaft, creating a compact assembly that maintains vibration functionality while minimizing overall device size.
Solution Approach 2:
The vibration apparatus is nested within the cup structure, with the motor and eccentric block arranged to utilize the internal space efficiently. The telescopic stroke mechanism is integrated into the cup body, allowing the vibration apparatus to be contained within the overall device footprint.
2Productivity
If the deceleration ratio of the gear box is reduced, then telescopic frequency increases, but telescopic force becomes insufficient
Solution Approach 1:
The patent optimizes the deceleration ratio of the gear box to achieve a balance between telescopic frequency and force. By carefully selecting the gear ratio parameters, the system achieves high telescopic frequency while maintaining sufficient telescopic force for effective vibration transmission to the penis.
Solution Approach 2:
The use of an eccentric block with a curved surface allows for smooth, continuous vibration transmission. The eccentric block's rotational motion converts rotational kinetic energy into vibrational motion, maintaining both frequency and force effectiveness through the curved geometry of the vibration transmission path.
3Volume of moving object
If the vibration apparatus size is reduced, then compactness is achieved, but vibration amplitude and effectiveness may decrease
Solution Approach 1:
The motor is pre-positioned at the bottom of the cup with the eccentric block mounted on its output shaft, creating a compact assembly that maintains vibration functionality while minimizing overall device size.
Solution Approach 2:
The eccentric block rotates at high speed to generate centrifugal force that drives the cup body to vibrate in different directions. This mechanical vibration mechanism achieves strong vibration amplitude within a compact structure by utilizing the rotational motion of the eccentric block rather than requiring large linear displacements.

AI summary
A vibration apparatus (1), and a masturbation cup (7) and vibration rod (14) comprising the vibration apparatus (1). The vibration apparatus (1) comprises a motor (2), a speed reduction mechanism and a rotating body. The output of the motor (2), after being decelerated by the speed reduction mechanism, drives the rotating boy to rotate. The rotating body is an eccentric structure, internally provided with a cavity. The motor (2) and the speed reduction mechanism are both arranged in the internal cavity of the rotating body. In the present vibration apparatus (1), by means of a built-in high-speed rotating ball, centrifugal forces in different directions are generated by means of high-speed rotation of the eccentric ball, such that a cup body (10) of the masturbation cup (7) is driven to move in various directions, so that requirements of vibration strength and vibration amplitude can be met, and requirements of high telescopic frequency and strength can also be met
