Penile Tumescence Device Axial Radial Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current measurement techniques for penile tumescence and rigidity, such as the Rigiscan, are invasive, impractical, and only provide intermittent data, failing to capture continuous axial and radial rigidity measurements, which limits their effectiveness in diagnosing erectile dysfunction.
Innovation Solution
A device with axial and radial monitoring means using sensors with different elasticity to measure penile rigidity and tumescence continuously, comprising strain gauge or extensometer sensors applied in the axial and radial directions, allowing for real-time data collection and analysis of physiological parameters like hardness and diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If prior art measurement techniques (Rigiscan) are used, then measurement function is provided, but the device is invasive and impractical
Solution Approach 1:
The patent replaces invasive mechanical measurement systems with non-invasive optical sensing technology. Optical sensors detect penile rigidity and tumescence through light interaction with tissue, eliminating the need for invasive mechanical probes while maintaining measurement capability. This substitution directly resolves the contradiction by removing invasiveness while preserving the core measurement function.
2Loss of information
If prior art measurement techniques are used, then intermittent data is obtained, but continuous monitoring is not achieved
Solution Approach 1:
The patent implements continuous monitoring through multiple optical sensors that continuously track penile rigidity and tumescence parameters throughout the nocturnal period. The system captures real-time data across the entire duration of sleep cycles, providing uninterrupted measurement coverage rather than intermittent snapshots. This ensures complete data capture for accurate NPT assessment.
3Measurement precision
If single-direction sensors are used, then simple measurement is achieved, but comprehensive rigidity assessment is limited
Solution Approach 1:
The patent employs sensors arranged in multiple spatial dimensions (axial and radial directions) to capture comprehensive rigidity characteristics. By measuring rigidity along different anatomical axes simultaneously, the system obtains a complete three-dimensional understanding of penile rigidity, significantly improving measurement precision while the modular sensor design keeps device complexity manageable.
4Loss of information
If measurement device covers full penile length, then comprehensive data is obtained, but device size and complexity increase
Solution Approach 1:
The patent divides the measurement device into multiple modular sensor segments distributed along the penile length. Each segment contains optimized sensing elements that independently contribute to the overall measurement. This segmentation allows comprehensive coverage of the entire penile structure while keeping each individual module compact and manageable, avoiding a single large complex device.
