Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing treatments are used for premature ejaculation, then ejaculation control is provided, but effectiveness in controlling ejaculation timing and duration is inadequate

Engineering Contradiction:

Improveeffectiveness of ejaculation controlVSAvoidcontrol over ejaculation timing and duration

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces mechanical or behavioral techniques with an electrical stimulation system. electrodes deliver controlled electrical fields to specific perineal muscles and nerves, substituting manual control methods with an automated electrical mechanism that provides more reliable and adjustable ejaculation control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs adjustable electrical parameters (voltage, current, pulse duration, frequency) to optimize ejaculation control effectiveness. By changing these electrical parameters, the system can adapt to different treatment needs and maximize control over ejaculation timing and duration beyond what fixed existing treatments provide.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If existing devices are used for perineal electrification, then ejaculation control is achieved, but discomfort is caused to the subject

Engineering Contradiction:

Improveejaculation control capabilityVSAvoiddiscomfort to subject

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies electrical stimulation locally to specific perineal muscles and nerves rather than generalized stimulation. This localized approach targets the bulbospongiosus and ischiocavernosus muscles specifically, providing effective ejaculation control while minimizing discomfort to surrounding tissues and the subject overall.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses dynamically adjustable electrical parameters that can be modified during treatment. The system can adapt voltage, current, and pulse characteristics in real-time based on subject response, allowing effective control while minimizing discomfort by reducing stimulation intensity when needed.

Inventive Principle:

Principle #15Dynamics

3Duration of action of moving object

If electrodes are positioned to target perineal tissues, then ejaculation latency time is prolonged, but device complexity increases

Engineering Contradiction:

Improveejaculation latency timeVSAvoidelectrode positioning and parameter control

Core Design Contradiction:

Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The patent pre-positions electrodes on the perineum before electrical stimulation begins. The electrode placement is established in advance targeting specific muscles, allowing the system to prolong ejaculation latency time without requiring complex real-time positioning adjustments during treatment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses a multi-functional control system that manages both electrode positioning and multiple electrical parameters (voltage, current, pulse duration, frequency) through a single integrated controller. This universal control approach manages device complexity by consolidating multiple functions into one system rather than requiring separate mechanisms for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)
