Solution Overview

Problem

Existing sex toys provide monotonous stimulation, failing to satisfy users due to insufficient stimulation effects.

Innovation Solution

A sex toy design featuring rotatable massage rollers that stimulate opposite sides of the penis, combined with a clamping mechanism and drive mechanism to adjust the position and movement of the rollers for personalized massage, and a second massage portion for comprehensive stimulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If vibration motors are used for stimulation, then the device can provide sexual pleasure, but the stimulation becomes monotonous and insufficient

Engineering Contradiction:
Improvestimulation varietyVSAvoidstructure simplicity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into multiple independent massage rollers (first massage roller and second massage roller) that can be arranged in different configurations. Each roller can be independently controlled to provide different massage patterns, replacing the single vibration motor approach and enabling diverse stimulation without excessive complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The massage rollers are designed to be rotatable with adjustable speeds and directions. The rotation speeds of the first and second massage rollers can be independently controlled, allowing dynamic adjustment of massage intensity and patterns, thereby providing varied stimulation experiences

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple massage rollers are added to provide varied stimulation, then stimulation effectiveness improves, but device complexity increases

Engineering Contradiction:
Improvestimulation effectivenessVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The first and second massage rollers serve multiple functions: they can rotate in different directions, operate at different speeds, and be controlled independently or simultaneously. This multi-functionality allows a relatively simple structure to achieve complex massage patterns, improving stimulation effectiveness without proportionally increasing device complexity

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

Solution Approach 2:

The device combines the functions of multiple massage rollers into a unified structure with shared control mechanisms. The first and second massage rollers work together in coordinated patterns, merging their individual capabilities to provide comprehensive stimulation while maintaining structural integration

Inventive Principle:
Principle #5Merging (Combining)
