Solution Overview

Problem

Existing ejaculation promotion devices face issues with excessive air pressure causing discomfort, difficulty in moving the penis, and inefficient stimulus delivery due to sealed spaces, which can lead to incomplete ejaculation and increased manufacturing costs from excessive use of gel-like resin.

Innovation Solution

The design incorporates non-closed air cells between the core member and container body, utilizing adjustable air pressure and air resistance members to provide a variable stimulus and reduce material usage, allowing for easier operation and cost-effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If sealed empty spaces are formed between the container body and core member, then air pressure stimulus is enhanced, but excessive pressure causes discomfort and difficulty in moving the penis

Engineering Contradiction:
Improveair pressure stimulusVSAvoidexcessive pressure discomfort
Core Design Contradiction:
ForceVSObject-affected harmful factors

Solution Approach 1:

The core member is designed with a porous structure that allows air to pass through, transforming the sealed empty spaces into non-closed air cells. This enables the air pressure stimulus to be regulated as air can escape through the porous core member, preventing excessive pressure buildup while maintaining the beneficial air cushion effect for stimulus enhancement.

Inventive Principle:
Principle #31Porous materials

2Force

If sealed empty spaces are formed, then air cushion function is maximized, but air removal becomes impossible causing vacuum state and adhesion

Engineering Contradiction:
Improveair cushion functionVSAvoidpenis movement freedom
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The porous structure of the core member allows air to be removed from the insertion empty space as the penis moves, preventing vacuum state formation. Air can escape through the porous walls of the core member, eliminating the adhesion problem while maintaining the air cushion function for effective stimulus delivery during movement.

Inventive Principle:
Principle #31Porous materials

3Force

If ribs are provided in mesh manner to form sealed spaces, then stimulus enhancement is improved, but manufacturing cost increases due to excessive gel-like resin usage

Engineering Contradiction:
Improvestimulus enhancementVSAvoidmanufacturing cost
Core Design Contradiction:
ForceVSEase of manufacture

Solution Approach 1:

The porous structure eliminates the need for complex mesh rib configurations to create air cells, as the porosity itself provides the air passage function. This simplifies the core member design, reduces the amount of gel-like resin required, and lowers manufacturing costs while maintaining the stimulus enhancement effect through the porous air cell structure.

Inventive Principle:
Principle #31Porous materials

4Stress or pressure

If completely airtight sealed spaces are formed, then pressure application is maximized, but penis rubbing movement becomes difficult

Engineering Contradiction:
Improvepressure application to penisVSAvoidrubbing movement smoothness
Core Design Contradiction:
Stress or pressureVSEase of operation

Solution Approach 1:

The porous core member allows pressure to be applied to the penis through the air cushion effect while simultaneously allowing air to escape as the penis moves back and forth. This prevents pressure buildup that would resist movement, enabling smooth rubbing motion while maintaining effective pressure application for stimulus enhancement.

Inventive Principle:
Principle #31Porous materials

AI summary

Provided are an ejaculation promotion apparatus and an ejaculation promotion device by which a varied stimulus and tightening force by an appropriate pressure can be obtained, by using an air pressure in a non-closed air cell formed between a core member and a container as a pressure source that provides a stimulus and tightening force to a penis. Included are a core main body (31) including an insertion inlet (33) and an insertion empty space (35), a plurality of first ribs (40) projectingly provided on an outer peripheral surface of the core main body at necessary intervals, and extending in an approximately the same direction, and an air resistance member (50) that allows passage of air along a flow path F while serving as a resistance against the air flowing in the flow path at the time of expansion of an outer diameter of the core main body.
