Solution Overview

Problem

Existing sexual stimulation devices often suffer from hygiene issues due to direct contact with the genital area and can be unreliable when pressed firmly against the skin, especially those using air and sound waves, which may cease to function under load.

Innovation Solution

A stimulation device with a silicone-covered housing and motor that generates stimulation patterns through air flow and sound waves, featuring a sensor to detect output and a controller to maintain function even when pressed firmly, ensuring continuous operation and hygiene by preventing bacterial buildup and liquid exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If direct contact between the genital area and the exterior of a stimulation device is used, then pleasurable sensations are provided, but hygiene is reduced and skin irritation occurs

Engineering Contradiction:

Improvepleasurable sensationsVSAvoidhygiene and skin irritation

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces air and sound waves as intermediary elements between the stimulation device and the user's body. The device manipulates air flow and generates sound waves that transmit through the body tissue to provide stimulation without direct contact between the device exterior and the genital area, thus maintaining hygiene while delivering pleasurable sensations

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical vibration contact with acoustic wave transmission. Instead of using a vibrating surface that directly contacts the body, the device uses a motor to generate sound waves that propagate through the body tissue, substituting mechanical contact with acoustic energy transmission

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If air and sound waves are used to stimulate an erogenous zone, then indirect stimulation is provided, but the device becomes unreliable when pressed firmly against the skin

Engineering Contradiction:

Improveindirect stimulationVSAvoidfunction under load

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent incorporates a sensor that detects the output produced by the motor and provides feedback to the controller. When the device is pressed firmly against the skin causing increased load on the motor, the sensor detects the decreased motor output and signals the controller to compensate by adjusting power delivery, thereby maintaining reliable operation under varying load conditions

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent makes the device's power delivery dynamic rather than static. The controller continuously adjusts the power supplied to the motor based on real-time feedback from the sensor, allowing the device to adapt its operation to maintain consistent performance whether lightly or firmly pressed against the skin

Inventive Principle:

Principle #15Dynamics

3Reliability

If the motor operates continuously under varying load, then stimulation is maintained, but energy consumption increases

Engineering Contradiction:

Improvecontinuous operationVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent dynamically changes the power delivery parameters based on actual motor load conditions. Rather than operating at constant maximum power, the controller adjusts electrical parameters (voltage, current) to match the actual needs of the motor, reducing energy consumption during light operation while maintaining sufficient power during heavy load conditions

Inventive Principle:

Principle #35Parameter changes
