Solution Overview
Problem
Existing sexual products with dual motors and cam mechanisms suffer from large volume, high cost, non-linear motion, and monotonous stimulation due to motor interference, leading to suboptimal user experience.
Innovation Solution
A dual-drive structure utilizing a single rotating motor with a driving mechanism that converts rotational motion into vertical reciprocating motion through a driving block and groove, enabling two stimulation modes with linear and high-frequency movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual motors with cam mechanisms are used to drive telescoping and swinging structures, then the massage function is achieved, but the volume and cost increase significantly
Solution Approach 1:
The patent combines two separate driving functions (telescoping and swinging) into a single driving mechanism. The rotating motor drives a driving block that moves along a driving groove, which in turn drives both the telescoping structure and the swinging structure through mechanical linkage, eliminating the need for dual motors and reducing overall device volume.
Solution Approach 2:
The single rotating motor with driving block and groove mechanism serves multiple functions simultaneously. The same driving mechanism produces both the telescoping motion and the swinging motion, allowing one motor to perform what previously required two motors, thus reducing volume and cost.
2Adaptability or versatility
If dual motors with cam mechanisms are used, then the massage function is achieved, but the production cost increases significantly
Solution Approach 1:
The patent merges two separate motor systems into one integrated driving mechanism. The rotating motor with driving block and groove replaces two cam mechanism systems, reducing component count and assembly complexity, which directly lowers production costs while maintaining the dual massage function.
Solution Approach 2:
The patent extracts and eliminates the expensive cam mechanism components in favor of a simpler driving block and groove system. This substitution removes the need for precision-cam manufacturing and reduces the overall bill of materials, thereby reducing production cost while maintaining functional equivalence.
3Adaptability or versatility
If cam mechanisms are used to drive the structures, then the massage function is achieved, but the motion becomes non-linear and frequency is limited
Solution Approach 1:
The patent employs a dynamic driving block that moves along the driving groove in a controlled manner. The driving block's motion along the groove's contours enables the transmission of dynamic forces, allowing for higher frequency movements and more linear motion patterns compared to the fixed cam profile approach, thereby improving motion frequency and linearity.
4Adaptability or versatility
If dual motors are used to achieve two stimulation modes, then the versatility is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines two separate motor-driven systems into a single integrated mechanism. The rotating motor with driving block and groove produces both stimulation modes through mechanical linkage, reducing the number of components and simplifying the overall structure while maintaining the ability to provide diverse sexual stimulation.
Solution Approach 2:
The single driving mechanism serves multiple functions by producing both telescoping and swinging motions through one motor. This universal mechanism eliminates the need for separate motors for different stimulation modes, reducing device complexity and cost while maintaining versatility.
