Solution Overview

Problem

Conventional stimulation devices for sensitive body parts, such as the clitoris, face limitations in design and function due to the use of membranes, which restrict the maximum volume change and amplitude of pressure waves, leading to design and implementation challenges.

Innovation Solution

A stimulation device with a cavity having a circumferential side wall that is continuously variable in length, allowing the distance between the ends to change between a minimum and maximum value, enabling greater volume change and amplitude of pressure waves without design restrictions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a conventional membrane is used to close the cavity, then the device structure is simple, but the maximum volume change and amplitude of pressure waves are limited

Engineering Contradiction:
Improvevolume change of cavityVSAvoidstructure complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The side wall is designed as a dynamic structure with variable length instead of a fixed membrane. The side wall can be extended or retracted along its longitudinal axis, allowing the cavity volume to change dynamically between minimum and maximum values, thereby overcoming the volume limitation of conventional membranes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The side wall is divided into multiple sections, with at least one section being the variable length structure. This segmentation allows the side wall to achieve extension and retraction functionality while maintaining structural integrity, resolving the contradiction between volume change capability and structural simplicity.

Inventive Principle:
Principle #1Segmentation

2Stress or pressure

If a conventional membrane is used, then the device is easy to manufacture, but the amplitude of pressure waves is restricted

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The variable length side wall enables dynamic adjustment of cavity volume, which directly increases the amplitude of pressure waves generated during stimulation. This dynamic structure allows for greater pressure wave amplitude compared to fixed membranes, while the modular design keeps manufacturing complexity manageable.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The side wall's length parameter is made variable, allowing the cavity volume to change between minimum and maximum values. This parameter change enables the generation of pressure waves with higher amplitude, overcoming the limitation of conventional membranes with fixed geometry.

Inventive Principle:

Core Design Contradiction:

Solution Approach 1:

The variable length side wall creates a dynamic cavity volume that can be adjusted between minimum and maximum values. This dynamic volume change generates more effective stimulating pressure fields with higher amplitude waves, improving reliability of the stimulation effect while the segmented design controls structural complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The side wall's length in the longitudinal dimension is made variable, adding a degree of freedom to the cavity volume control. This dimensional change enables greater pressure wave amplitude and improved stimulation effectiveness without proportionally increasing overall device complexity.
