Solution Overview

Problem

Existing sex toys provide limited stimulation range and unsatisfactory stimulation effects, failing to adequately satisfy human physiological and psychological needs during sexual activity.

Innovation Solution

A massage device with a shell, driving assembly, and annular belt-like massage member that rotates within the shell, providing a kneading effect through the rotation of the massage member, which enlarges the stimulation range and enhances the stimulation effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a motor drives the massage head to do linear reciprocating motion, then the device structure is simple, but the stimulation range is limited and stimulation effect is unsatisfactory

Engineering Contradiction:
Improvedevice structureVSAvoidstimulation range
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The massage member is designed to perform both linear reciprocating motion and rotational motion simultaneously. The linear motion is achieved through the motor driving the massage head, while the rotational motion is achieved through the annular belt structure that rotates around the driving wheel. This dynamic combination of motion types enlarges the stimulation range and improves the stimulation effect without significantly increasing device complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention adds a rotational dimension to the traditional linear reciprocating motion. The massage member not only moves back and forth along the longitudinal axis but also rotates around its own axis. This dimensional addition transforms the stimulation from a single-direction linear contact to a multi-directional contact that covers a larger area and provides more comprehensive stimulation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If a motor drives the massage head to do linear reciprocating motion, then the device structure is simple, but the stimulation effect is unsatisfactory

Engineering Contradiction:
Improvedevice structureVSAvoidstimulation effect
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The dual motion pattern (linear reciprocating + rotational) creates a more effective stimulation mechanism. The rotation of the massage member allows different portions of its surface to contact the human body during the reciprocating motion, generating a kneading effect that significantly enhances the stimulation effect and makes it easier for users to reach orgasm.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The massage member adopts an annular belt shape with a curved surface that contacts the human body. This curved geometry, combined with rotational motion, creates a kneading effect that is more effective than linear motion alone. The spherical/curved surface ensures better contact and distribution of force across the stimulation area.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Area of stationary object

If the massage member extends into the moving space and rotates, then the stimulation range is enlarged, but the device complexity increases

Engineering Contradiction:
Improvestimulation rangeVSAvoiddevice structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The annular belt structure serves multiple functions: it acts as the massage member that contacts the human body, it functions as a transmission element that rotates around the driving wheel, and it provides the structural framework for achieving both linear and rotational motion. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the massage function and the motion transmission function into a single integrated structure. The annular belt既是 the massage element that directly contacts the human body,又是 the transmission element that rotates around the driving wheel and driven wheel. This merging of functions simplifies the overall device structure while achieving the desired rotational motion and enlarged stimulation range.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A massage device includes a shell configured to be inserted into the human body, a driving assembly supported by the shell, and a massage member. The shell defines a moving space therein, and the moving space communicates with an external environment out of the shell. The driving assembly includes a driving wheel and a driven wheel cooperating with the driving wheel. The massage member is shaped as an annular belt and mounted around the driving wheel and the driven wheel, and at least partly extends into the moving space of the shell. The driving wheel engages with the massage member to drive the massage member to rotate, generating a kneading stimulation effect on the human body.
