Solution Overview

Problem

Existing adult products are designed primarily for single-gender use and focus on unidirectional stimulation, failing to provide a synchronized and interactive experience for couples, thus limiting their applicability and market expansion.

Innovation Solution

A bidirectional stimulation massage device featuring a thin-walled structure with a channel, a first stimulation device arranged between the inner and outer walls, and an electric stimulation assembly with a mechanical vibration module, capable of providing simultaneous massage stimulation to both the penis and the inner wall of the vagina.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If adult products are designed for single-gender use with unidirectional stimulation, then the product structure can be simple and focused, but the applicability scope is limited and interactive experience is lost

Engineering Contradiction:
Improveapplicability scopeVSAvoidproduct structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The massage device is designed with a thin-walled structure that can be worn by either gender, featuring stimulation devices on both inner and outer walls to provide bidirectional stimulation. This universal design allows the same product to serve both male and female users, expanding applicability scope while maintaining a relatively integrated structure rather than requiring separate gender-specific products

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

Solution Approach 2:

The device divides the thin-walled structure into functional zones with stimulation devices positioned at different locations (inner wall and outer wall). This segmentation allows independent stimulation of different body parts while using a single integrated device, achieving multi-functionality without proportionally increasing overall structural complexity

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If adult products focus on unidirectional stimulation for one partner, then the device design is simple, but the interactive experience and emotional communication between partners is insufficient

Engineering Contradiction:
Improveinteractive experienceVSAvoidstimulation system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device merges stimulation functions for both partners into a single wearable unit. The thin-walled structure allows simultaneous contact with both the wearer's body (inner wall stimulation) and the partner's body (outer wall stimulation), creating integrated bidirectional interaction rather than requiring separate devices for each partner

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention adds a spatial dimension to stimulation by utilizing the thin-walled structure's dual-sided design. Instead of unidirectional stimulation from one direction, the device enables stimulation from both inner and outer walls simultaneously, creating a multi-dimensional interactive experience that enhances emotional connection

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

3Adaptability or versatility

If invasive stimulation devices are used for strong physiological stimulation, then the stimulation effect is intense, but the product is suitable for only one gender and cannot satisfy both partners simultaneously

Engineering Contradiction:
Improvegender applicabilityVSAvoidinvasiveness
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The device uses a thin-walled flexible structure that can adapt to different body shapes and genders. This flexible shell design allows the same device to be worn by either gender while providing effective stimulation through its inner and outer walls, eliminating the need for gender-specific invasive devices and reducing harm through non-invasive wearable design

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

Disclosed is a bidirectional stimulation massage device, which includes a thin-walled structure having a channel, an inner wall and an outer wall, and a first stimulation device, where the first stimulation device is arranged in a position at a non-end portion of the thin-walled structure and is configured to provide massage stimulation to both the inner wall and the outer wall at the same time. The device can apply pressure and friction in an active or passive manner by introducing the first stimulation device, which not only provides stronger physical stimulation, but also enhances psychological excitement and satisfaction of a user. Further, the first stimulation device can facilitate the bidirectional stimulation massage to both male and female male reproductive organs at the same time according to actions of the user, thereby strengthening emotional connection and interactive pleasure between partners.
