Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for erectile dysfunction, such as drug therapy and mechanical devices, provide limited and temporary solutions, often with side effects and are not effective for chronic conditions, particularly for men with heart conditions or those seeking aesthetic improvements in erections.
Innovation Solution
A non-invasive system that applies alternating phases of sub-atmospheric and above atmospheric pressure, or mechanical force, synchronized with the cardiac pulse-wave to induce cyclic augmented penile blood volume changes, improving endothelial function and tissue elasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vacuum pump is used to draw blood into the penis, then erection is achieved, but the erection is less aesthetically pleasing and cooler in temperature
Solution Approach 1:
The patent applies periodic pressure cycles alternating between negative pressure (to draw blood in) and positive pressure (to maintain and enhance erection quality). This periodic action allows the system to achieve reliable erections while improving aesthetic appearance by controlling blood flow dynamics and temperature through repeated pressure phases.
Solution Approach 2:
The system dynamically changes pressure parameters over time, transitioning from negative pressure during the drawing phase to positive pressure during the maintenance phase. This parameter change enables the system to overcome the limitations of constant negative pressure vacuum pumps, achieving both reliable erection achievement and improved aesthetic appearance through controlled pressure variation.
2Duration of action of stationary object
If compression ring is used to maintain erection, then erection is maintained for approximately 30 min, but it can be painful due to tight constriction
Solution Approach 1:
Instead of continuous compression, the patent uses periodic pressure application with cycles of negative and positive pressure. This periodic action maintains erection duration by repeatedly stimulating blood flow into the penis while avoiding continuous constriction, thereby reducing pain while preserving the duration benefit.
Solution Approach 2:
The system uses pneumatic pressure cycles to control blood flow dynamically. By alternating negative pressure (drawing blood in) and positive pressure (maintaining flow), the system achieves prolonged erection duration without the harmful continuous mechanical constriction of compression rings, eliminating pain while maintaining duration.
3Reliability
If phosphodiesterase type 5 inhibitors are used, then erectile function is improved, but side effects occur such as headaches, gastrointestinal upsets, and blurred vision
Solution Approach 1:
The patent replaces pharmacological intervention with a mechanical pressure-based system. By using controlled negative and positive pressure cycles to directly manipulate blood flow into the penis, the system achieves reliable erectile function improvement without involving chemical substances, thereby eliminating all drug-related side effects while maintaining therapeutic effectiveness.
4Loss of time
If vacuum pump is used just prior to sexual intercourse, then temporary solution is provided, but no reasonable treatment for chronic condition exists
Solution Approach 1:
The patent employs periodic pressure therapy that can be applied repeatedly over time. This periodic action allows the system to serve both as a temporary solution prior to intercourse and as a chronic treatment regimen, where repeated sessions progressively improve endothelial function and tissue health, addressing both immediate and long-term needs.
Solution Approach 2:
The system performs preliminary action by repeatedly applying pressure cycles before sexual intercourse to ensure adequate erection. Simultaneously, these repeated preliminary actions accumulate therapeutic effects over time, improving vascular health and tissue elasticity chronically, thus transforming a temporary pre-intercourse aid into a sustained treatment for chronic conditions.
