Waterproof Sexual Stimulation Device With Sealed Pressure Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sexual stimulation devices with waterproof seals face issues with pressure gradients due to volume changes, which are often relieved through airholes or valves that compromise waterproofing and can lead to water ingress, contaminating internal components.
Innovation Solution
A closed-system pressure balancing mechanism using an active stretchable seal and a secondary passive stretchable element, such as a flexible capsule, to manage internal pressure without compromising waterproofing, where the passive element expands and contracts to balance pressure within a sealed compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If airholes or valves are used to relieve pressure gradients, then smooth operation of the device is ensured, but waterproofing is compromised and water may ingress to contaminate internal components
Solution Approach 1:
A breathable membrane is introduced as an intermediary component between the internal chamber and the external environment. This membrane allows pressure equalization through breathability while physically blocking water ingress, thus resolving the contradiction between needing pressure relief and maintaining waterproofing integrity
Solution Approach 2:
The patent employs a flexible breathable membrane as a thin film structure that can deform to accommodate pressure changes while maintaining its barrier function. This membrane flexes with pressure gradients to ensure smooth operation but prevents water penetration, solving both operational smoothness and waterproofing requirements
2Ease of operation
If airholes or valves are located close to the reciprocating element, then direct air path is created for smooth reciprocating motion, but water ingress risk increases due to weaker sealing
Solution Approach 1:
The breathable membrane serves as a mediator that allows the airhole to be positioned close to the reciprocating element for smooth motion while the membrane itself acts as the protective barrier against water, eliminating the need for separate valve structures that would compromise sealing
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
Maintains waterproof integrity by isolating the passive stretchable element from potential fluid ingress, ensuring the device operates effectively and safely without contamination of sensitive components.
Implementation Method 1
The change in volume within the waterproof skin may generate a pressure gradient with respect to the ambient pressure and this pressure gradient is often released by the use of air holes or valves
Implementation Method 2
A closed-system pressure balancing mechanism using an active stretchable seal and a secondary passive stretchable element, such as a flexible capsule, to manage internal pressure without compromising waterproofing

AI summary
A sexual stimulation device includes a housing, a drive unit at least partially disposed within the housing, a first stimulation element directly or indirectly coupled with the drive unit and driven by the drive unit to generate a movement, the movement configured to stimulate a sensitive area of a human body, and a removable attachment having a second stimulation element coupled with the first stimulation element and configured to reciprocate with a reciprocating movement of the first stimulation element.
