Solution Overview

Problem

Existing male penis stimulation devices provide unsatisfactory stimulation, are unwieldy due to large housings, lack adaptability to different penis sizes, and are difficult to clean, often requiring lubrication to prevent skin irritation.

Innovation Solution

A stimulation device with an applicator and a pressure field generating device that applies a contactless pneumatic alternating pressure field to the penis, using an applicator with a pressure chamber and sealing device to ensure effective stimulation without direct contact, allowing for modular design and easy cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the entire penis is inserted into a closed receiving chamber for stimulation, then stimulation function is provided, but the device becomes unwieldy due to large housing and is difficult to clean

Engineering Contradiction:
Improvestimulation functionVSAvoidcleaning ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device is divided into a reusable pressure field generating device and a disposable applicator. The applicator contains the receiving chamber and contact structures, while the pressure field generating device contains the pump and control systems. This segmentation allows the applicator to be discarded after use, eliminating cleaning requirements, while the pressure field generating device can be easily wiped clean.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The receiving chamber and contact structures are extracted from the pressure field generating device and placed in the disposable applicator. This extraction removes the components that require extensive cleaning from the permanent device, simplifying maintenance while preserving the stimulation function.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a closed receiving chamber is used for stimulation, then stimulation effect is achieved, but lubricant is necessary to prevent skin irritation caused by friction

Engineering Contradiction:
Improvestimulation effectVSAvoidskin irritation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The applicator is designed as a disposable component that is discarded after a single use. This eliminates the need for lubricant and cleaning, as the applicator is replaced rather than reused. The disposable nature ensures no skin irritation from residual lubricant or bacterial growth, while maintaining effective stimulation during the single use period.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Device complexity

If a standard size receiving chamber is used, then device complexity is reduced, but adaptability to different penis sizes is insufficient

Engineering Contradiction:
Improvesize varietyVSAvoidadaptability to different penis sizes
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The device offers multiple applicator sizes (small, medium, large) that can be selected based on user needs. Each applicator is optimized for specific penis sizes, providing effective stimulation without requiring the single device to accommodate all sizes through complex adjustable mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pressure field generating device serves as a universal platform that can work with multiple applicator sizes. The standardized connection interface allows one pressure field generating device to control different sized applicators, providing size adaptability without requiring multiple complete device systems.

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

4Device complexity

If manual movements are performed for stimulation, then device complexity is reduced, but stimulation effectiveness is insufficient compared to automatic devices

Engineering Contradiction:
Improveautomation mechanismVSAvoidstimulation effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The pressure field generating device creates alternating pressure fields that cause rhythmic expansion and contraction of the receiving chamber. This mechanical vibration provides automatic stimulation that is more effective than manual movements, while keeping the device relatively simple through the use of a basic pump mechanism.

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The device uses a pneumatic system with a pump to generate alternating positive and negative pressure fields within the receiving chamber. This pneumatic mechanism automates the stimulation process, providing consistent and effective stimulation without requiring complex mechanical actuators or motors.

Inventive Principle:
Principle #29Pneumatics and hydraulics

AI summary

The invention relates to a stimulation device for a male penis comprising a pressure field generation unit (1) for generating a pneumatic pressure field and an applicator (11) for applying the pressure field to a part of the penis to be stimulated. The applicator (11) has a pressure chamber (2) which can receive a pressure field generated by the pressure field generation unit (1). The pressure chamber (2) has an opening (3) in a contact area (31) of the applicator (11), so that the pressure field can be applied directly to a part of the penis to be stimulated via the opening (3). A sealing device (32) is arranged on the applicator (11), which is configured to seal the pressure chamber (2) from the environment when the applicator (11) is applied to the penis.
