Solution Overview

Problem

Existing sexual stimulation devices, such as vibrators, can cause skin irritation and hygiene issues, and direct contact may not be desirable for some users, while indirect stimulation methods like using the clitoral hood are often more pleasurable but not effectively simulated by current devices.

Innovation Solution

A stimulation device with a pressure generator that uses a chamber with a movable container and a drive unit to create alternating positive and negative pressures, mimicking natural sexual stimulation through a suction effect, enhancing blood circulation and sensitivity without direct contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If vibrators are used to apply direct contact stimulation, then sexual stimulation effect is improved, but skin irritation and hygiene issues worsen

Engineering Contradiction:
Improvestimulation effectVSAvoidskin irritation
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a pressure generator as an intermediary device that applies stimulation through pressure changes rather than direct contact. The device uses a chamber with movable and stationary components to generate pressure variations that stimulate the erogenous zone indirectly, eliminating the need for direct contact between the vibrator and skin, thus reducing skin irritation and hygiene issues while maintaining stimulation effectiveness

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If direct contact stimulation is used, then sexual stimulation effect is improved, but hygiene and personal reservation issues worsen

Engineering Contradiction:
Improvestimulation effectVSAvoidhygiene issues
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The pressure generator serves as a non-contact intermediary that transmits stimulation through pressure waves. The device comprises a chamber with a movable container and stationary sleeve that work together to generate pressure variations without requiring direct skin contact, thereby addressing hygiene concerns and personal reservations while maintaining effective stimulation

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If pressure generator with movable container is used, then realistic simulation of natural stimulation is improved, but device complexity worsens

Engineering Contradiction:
Improverealistic simulationVSAvoidchamber structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs a nested structure where a movable container is positioned within a stationary sleeve, both housed within a chamber. The movable container includes a movable member that reciprocates within the chamber, creating a compact integrated assembly. This nesting arrangement enables realistic simulation of natural stimulation through coordinated movements while managing device complexity through space-efficient design

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

Embodiments of the present disclosure disclose a stimulation device. The stimulation device includes a pressure generator comprising a chamber including a bottom wall and an opening configured to engage a portion of a body of a user, a drive unit, and a linear reciprocating mechanism. The drive unit is configured to cause reciprocating motion of the bottom wall via the linear reciprocating mechanism, thereby resulting in a changing volume of the chamber. The pressure generator further comprises a stationary sleeve and a motional sleeve, with motional sleeve disposed between the stationary sleeve and the bottom wall, such that, stationary sleeve and the motional sleeve are concentric with each other and define the chamber with the bottom wall.
