Innovation Solution
A device with a housing containing a handle section and stimulation section, a drive unit, a pressure chamber, a movable chamber wall section, and a housing opening, utilizing a coil assembly within a stationary magnetic field to generate a variable pressure field through alternating currents, allowing for overpressures and underpressures for non-contact stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotating electric motor with eccentric shaft is used, then the piston can be moved repeatedly, but the piston stroke is fixed and cannot be changed during operation
Solution Approach 1:
The patent replaces the mechanical eccentric shaft mechanism with an electromagnetic linear motor that uses a magnetic core and coil elements. This substitution allows the piston stroke to be variable and adjustable during operation, as the magnetic field strength can be controlled electronically rather than being fixed by mechanical geometry.
Solution Approach 2:
The patent implements a dynamic drive system where the piston stroke can be changed during operation through control of the electromagnetic field. The magnetic core can be axially displaced by varying the control current, enabling real-time adjustment of the piston stroke length without changing the physical structure.
2Adaptability or versatility
If an electric linear motor with magnetic core is used, then variable piston stroke is achieved, but the maximum axial displacement is determined by the number, design, arrangement and circuitry of the coils
Solution Approach 1:
The patent changes the operating parameters of the electromagnetic linear motor by varying the control current supplied to the coil elements. This allows the magnetic core to be axially displaced to different positions, creating variable piston strokes and vibration frequencies without changing the physical coil arrangement.
Solution Approach 2:
The patent uses periodic alternating current to drive the magnetic core back and forth axially, creating rhythmic piston movement. The frequency and amplitude of the periodic action can be adjusted by modifying the electrical characteristics of the control current.
3Adaptability or versatility
If a fixed piston stroke is used, then the device structure is simple, but the frequency of vibration cannot be varied
Solution Approach 1:
The patent replaces fixed mechanical linkages with an electromagnetic drive system where the piston stroke and vibration frequency can be independently controlled through electrical parameters. The magnetic core and coil arrangement allows for flexible control of both stroke length and frequency without complex mechanical adjustments.

AI summary
The invention relates to a device for stimulating the clitoris by means of a variable pressure field, comprising a housing (21) in which a handle section and a stimulation section are formed; a drive unit (32) which is arranged in the housing (21) and configured to repeatedly provide a drive movement; a pressure chamber (4) which is arranged in the housing (21) to provide a variable pressure field and is at least partially surrounded by a chamber wall; a movable chamber wall section which forms a section of the chamber wall and couples to the drive unit (32) such that the movable chamber wall section can be repeatedly moved between different wall positions in response to the drive movement coupled thereto, thereby repeatedly increasing and decreasing the chamber volume of the pressure chamber (4) to generate the variable pressure field;a housing opening (22) located in the stimulation section and in fluid communication with the pressure chamber (4), such that the variable pressure field generated by the pressure chamber (4) can be released via the housing opening (22) in the form of underpressure and overpressure; and a battery device (28) configured to provide drive energy for the drive device (32). In the drive device (32), a coil device, through which an electric current flows during operation, is movably arranged in an associated stationary permanent magnetic field and couples to the movable chamber wall section to transmit the drive movement. Furthermore, a method for generating a variable pressure field is provided. (Fig. 1b);
