Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stimulation devices for erogenous zones, particularly the clitoris, suffer from issues such as skin irritation, hygiene problems, habituation effects, and complexity, including direct contact irritations, manual operation annoyance, and hygienic issues with vacuum pumps.
Innovation Solution
A stimulation device with a flexible wall portion and a drive unit that creates modulated positive and negative pressures through a changing chamber volume, avoiding direct contact and using a closed system to prevent dehydration and contamination, with a simple construction and automatic pressure control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If direct contact stimulation devices (vibrators) are used on erogenous zones, then stimulation effectiveness is improved, but skin irritation and inflammation occur
Solution Approach 1:
The patent introduces an intermediary fluid medium (water or lubricant) between the stimulation device and the erogenous zone. The device delivers vibrations through this fluid medium rather than direct solid-to-skin contact, thereby maintaining stimulation effectiveness while preventing skin irritation and inflammation. The fluid acts as a buffer that transmits mechanical energy without direct mechanical contact.
2Object-affected harmful factors
If vacuum pumps are used for indirect stimulation, then direct contact irritation is avoided, but manual operation becomes annoying and distracting
Solution Approach 1:
The patent replaces the manual mechanical hand pump with an electrically driven vacuum pump. This substitution eliminates the need for manual operation, removing the annoyance and distraction associated with hand pumping while maintaining the indirect stimulation benefit of avoiding direct skin contact. The electrical drive provides automated, consistent vacuum generation.
Solution Approach 2:
The patent implements cyclic or pulsed vacuum operation instead of continuous vacuum. The vacuum pump operates in periodic cycles, creating alternating phases of negative pressure and atmospheric pressure. This periodic action maintains stimulation effectiveness while preventing habituation effects that would occur with continuous uninterrupted vacuum application.
3Reliability
If continuous negative pressure is applied by vacuum pumps, then clitoral engorgement is achieved, but habituation effects limit long-term effectiveness
Solution Approach 1:
The patent employs cyclic or pulsed vacuum operation where the vacuum pump alternates between creating negative pressure and releasing to atmospheric pressure. This periodic application of negative pressure achieves clitoral engorgement during the vacuum phases while preventing habituation effects by introducing intervals of normal pressure, thereby maintaining long-term effectiveness throughout extended use.
4Adaptability or versatility
If vacuum pumps with valves and complex pressure control are used, then pressure regulation is achieved, but device complexity increases
Solution Approach 1:
The patent utilizes the natural elastic resilience of the clitoris and surrounding tissues to automatically regulate pressure. When negative pressure is applied, the tissue expands and engorges, naturally limiting further pressure increase. When vacuum is released, the tissue's elastic recoil returns it to its original state. This self-regulating mechanism eliminates the need for complex valves and electronic pressure control systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides effective, hygienic, and non-habituating stimulation by mimicking natural sexual arousal, enhancing sensitivity without direct contact, and preventing skin drying, with easy operation and reduced risk of injury.
Implementation Method 1
A drive unit of the stimulation device is in physical communication with the flexible wall portion so as to cause deflections of the flexible wall portion in opposing directions, thereby resulting in a changing volume of the chamber
Implementation Method 2
The changing volume of the chamber results in modulated positive and negative pressures with respect to a reference pressure. The modulated positive and negative pressures are applied to a body part (e.g., a clitoris) through an opening of the stimulation device
