Solution Overview

Problem

Existing penis rings primarily rely on mechanical constriction for stimulation and erection enhancement, lacking a therapeutic effect, particularly in increasing sperm activity and male potency.

Innovation Solution

A penis ring with integrated LED light sources emitting blue and blue-violet light in the visible wavelength range (410-450 nm) for targeted irradiation, enhancing blood flow and sperm activity, combined with adjustable constriction for comfort and therapeutic efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blue and blue-violet light irradiation is added to the penis ring, then therapeutic effect and sperm activity increase, but device complexity increases

Engineering Contradiction:
Improvetherapeutic effectVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple light sources (blue and blue-violet LEDs) with power supply (accumulator), control circuitry, and mechanical constriction functions into a single integrated penis ring device. This merging approach delivers comprehensive therapeutic effects for improving sperm activity and erectile function while maintaining a compact, user-friendly form factor suitable for home use.

Inventive Principle:
Principle #5Merging (Combining)

2Illumination intensity

If multiple light sources are integrated into the penis ring, then stimulation effect is intensified, but ease of operation deteriorates

Engineering Contradiction:
Improvestimulation effectVSAvoidease of operation
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The penis ring incorporates an integrated accumulator (rechargeable battery) that automatically powers the light sources and control circuitry without requiring external power connections during use. The device can be recharged via USB connection, enabling convenient portable operation. This self-service design intensifies the stimulation effect through multiple LEDs while maintaining ease of operation through automatic power management and simple USB recharging.

Inventive Principle:
Principle #25Self-service

3Duration of action of moving object

If the penis ring is left on the penis for extended periods, then therapeutic effect increases, but comfort deteriorates

Engineering Contradiction:
Improvetreatment durationVSAvoidcomfort
Core Design Contradiction:
Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The penis ring uses periodic pulsed light emission rather than continuous illumination, with the control circuitry switching the LEDs on and off in controlled cycles. This periodic action allows the penis to receive therapeutic light doses over extended periods while providing rest intervals that prevent overheating and maintain comfort during prolonged treatment sessions.

Inventive Principle:
Principle #19Periodic action

4Reliability

If blue and blue-violet light is used for irradiation, then sperm activity increases, but energy consumption increases

Engineering Contradiction:
Improvesperm activityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent employs LEDs emitting in the blue and blue-violet wavelength ranges (400-480 nm), which have higher photon energy but are used at low power levels suitable for phototherapy. The control circuitry optimizes the duty cycle and intensity parameters to deliver effective therapeutic doses for improving sperm activity while minimizing overall energy consumption, enabling extended operation from a compact rechargeable accumulator.

Inventive Principle:
Principle #35Parameter changes
