Solution Overview

Problem

Existing massage devices fail to provide effective regional massage solutions, particularly in the field of sex toys, lacking the ability to achieve regional massage and resulting in poor massage experiences.

Innovation Solution

The device includes a shell comprising a head portion, a connecting portion, a connecting portion comprising a connecting portion, a connecting portion, a connecting portion comprising a connecting portion, a connecting portion, a connecting portion comprising a shell comprising a head portion, a connecting portion comprising a connecting portion comprising a connecting portion, a head portion, a handle, and a connecting portion, a connecting portion comprising a sub-massage portion, a sub-massage portion comprising a housing defined by a part of the shell, a movement space with a first opening, a driving device, and a massage head accommodated in the movement space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If massage modules use only insertable or tapping methods, then the structure is simple, but the massage area is limited and regional massage cannot be achieved

Engineering Contradiction:
Improvemassage areaVSAvoidstructure complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The massage module is divided into multiple independent massage heads (first massage head, second massage head, third massage head) that can operate simultaneously on different areas. Each massage head can be independently controlled to provide targeted massage to specific regions, thereby expanding the overall massage area without requiring a completely new device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from single-point or linear massage (insertable/tapping methods) to multi-point simultaneous massage by adding multiple massage heads positioned at different spatial locations. This dimensional expansion allows the device to cover a broader area and provide regional massage capabilities.

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

2Adaptability or versatility

If a single massage method is used, then the device is simple to operate, but the massage experience is poor and lacks variety

Engineering Contradiction:
Improvemassage method varietyVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The massage module integrates multiple massage functions into a single device, with different massage heads capable of performing various massage techniques simultaneously. The control system allows users to select different operational modes (e.g., simultaneous operation, sequential operation, or independent control of each head), providing versatile massage experiences while maintaining ease of operation through centralized control.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The device provides a wide massage area by simultaneously massaging three different areas, enhancing the massage experience with a reciprocating sliding mode and vibration effects, providing a more practical and effective massage experience.

Implementation Method 1

a driving device, and a massage head accommodated in the movement space. The driving device drives the massage head to move (e.g. vibration and swing) in the movement space

Methodology Applied
Scientific EffectVibration: Vibration

Implementation Method 2

The massage head slides reciprocally to massage through the driving device. The reciprocating sliding massage mode of a stimulating portion

Methodology Applied
Scientific EffectReciprocating motion:
