Solution Overview

Problem

Existing handheld sexual stimulation devices often limit stimulation to a single area and mode, failing to provide comprehensive or enhanced pleasurable experiences.

Innovation Solution

A sexual stimulation device with an elongated arm and paired stimulation portions that can swing, vibrate, and move in various planes and modes, allowing for multi-point stimulation and customizable motion patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a handheld stimulating device uses a single stimulation member with fixed texture and shape, then the device structure is simple, but the stimulation areas and modes are limited

Engineering Contradiction:
Improvestimulation areas and modesVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device divides the stimulation function into multiple independent stimulation members (first stimulation member, second stimulation member, third stimulation member) with different shapes, textures, and vibration characteristics. Each member can independently contact different areas, enabling multi-point simultaneous stimulation without requiring a complex single multifunctional component.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device integrates multiple stimulation members with different functions (vibration, rotation, pressing) into a single device structure. The first stimulation member provides vibration, the second provides rotation, and the third provides pressing, allowing one device to perform multiple stimulation modes that would otherwise require separate devices.

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

2Adaptability or versatility

If a stimulation device provides only one mode of stimulation, then the device structure is simple, but the pleasurable experience is limited

Engineering Contradiction:
Improvestimulation modesVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device incorporates multiple motors (first motor, second motor, third motor) that can be independently controlled to provide dynamic switching between different stimulation modes. The control circuit enables various combinations of vibration, rotation, and pressing modes to be activated simultaneously or sequentially, creating diverse stimulation experiences without requiring multiple separate devices.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a device stimulates only a single area, then the device structure is simple, but the comprehensive pleasure is limited

Engineering Contradiction:
Improvestimulation coverageVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device extends stimulation from a single point to multiple spatial dimensions by positioning three stimulation members at different locations and orientations. The first stimulation member contacts the front wall, the second contacts the side wall, and the third contacts the posterior wall, creating three-dimensional multi-point coverage that comprehensively stimulates different areas simultaneously.

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

AI summary

A sexual stimulation device includes: a main body; an elongated arm configured to be placed in a vagina, the elongate arm connected to the main body and including a first stimulation portion arranged at a distal end of the elongated arm away from the main body, the first stimulating portion configured for stimulating a first region; a second stimulation portion configured for stimulating a second region, the second region being different from the first region; and a third stimulation portion configured for stimulating a third region. The third region is different from the first stimulating region and the second stimulating region, the second stimulation portion and the third stimulation portion are respectively arranged at opposite sides of the elongated arm, a length of the second stimulation portion and a length of the third stimulation portion are shorter than a length of the elongated arm.
