Solution Overview

Problem

Existing sex toys provide limited stimulation range and unsatisfactory stimulation effect, failing to adequately satisfy human physiological and psychological needs.

Innovation Solution

A massage device with a shell, driving assembly, and massage member that generates a kneading effect through the rotation of the massage member, featuring an enlarged stimulation range and improved stimulation effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

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

Engineering Contradiction:

Improvestimulation rangeVSAvoidstimulation effect

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The massage member transitions from linear reciprocating motion to rotational motion, dynamically changing the movement pattern to enhance stimulation effectiveness and expand the stimulated area through circular kneading actions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The massage member extends both into the moving space and around the outer surface of the shell, adding a radial dimension to the stimulation coverage and enabling multi-dimensional contact with the human body for enhanced stimulation range

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the massage member partly extends into the moving space and partly surrounds the outer surface of the shell, then the stimulation range is enlarged, but the device structure becomes more complex

Engineering Contradiction:

Improvestimulation rangeVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The massage member serves multiple functions simultaneously: it rotates within the moving space to provide internal stimulation and extends around the outer surface of the shell to provide external stimulation, making the single component multi-functional and reducing the need for separate massage elements

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The massage member integrates the functions of internal and external massage components into a single unified structure, combining the moving space interaction and outer surface contact into one continuous rotational element, thereby simplifying the overall device structure while expanding stimulation range

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A massage device includes a shell defining a chamber and a moving space therein, a driving assembly supported by the shell, and a massage member. 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, one of the driving wheel and driven wheel is accommodated inside the chamber and another one of the driving wheel and driven wheel is accommodated inside the moving space. The massage member is mounted around the driving wheel and driven wheel, wherein the massage member partly extends into the moving space and partly surrounds an outer surface of the shell adjacent to the moving space.
