Solution Overview

Problem

Current urine flow measurement devices are inadequate for women and are often expensive, limiting their accessibility and effectiveness in diagnosing micturition disorders, which are more prevalent in women than men, and require specialized equipment and invasive testing.

Innovation Solution

A device comprising a truncated pyramid-shaped container with capacitive electrodes and sensors for precise urine flow measurement, capable of home use by both men and women, featuring a holder for versatile installation, and integrated sensors for temperature, movement, and spectrophotometric analysis to provide comprehensive diagnostic data without the need for specialized urodynamic examinations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional urine flow measurement devices are used, then measurement capability is provided, but they are suitable only for men and exclude women from accurate diagnostics

Engineering Contradiction:
Improvesuitability for both men and womenVSAvoidmeasurement accuracy for women
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The device is designed with a universal collection container and positioning system that accommodates both male and female anatomical differences. The container shape, opening size, and placement mechanisms are engineered to work effectively for all users regardless of gender, enabling the same device to serve multiple population groups accurately.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If specialized urodynamic examination equipment is used, then comprehensive diagnostic capability is achieved, but device complexity and cost increase significantly

Engineering Contradiction:
Improvecomprehensive diagnostic capabilityVSAvoidspecialized equipment requirements
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The device segments the diagnostic function into multiple independent sensors that measure different parameters (flow rate, volume, temperature, spectral properties). Each sensor is simple and independent, but together they provide comprehensive diagnostic capability that would otherwise require complex specialized equipment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A single device integrates multiple sensing capabilities (capacitive electrodes for flow and volume, temperature sensors, spectrophotometric sensors) to perform comprehensive urological diagnostics that traditionally required separate specialized devices and procedures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If multiple urine flow measurements are taken for precise diagnosis, then diagnostic accuracy improves, but time consumption and patient burden increase

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidtime for multiple measurements
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The device continuously records multiple parameters (flow rate, volume, temperature, spectral data) simultaneously throughout the entire urination process. This continuous multi-parameter monitoring provides comprehensive diagnostic information from a single measurement event, eliminating the need for multiple separate tests.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The device merges multiple measurement functions (uroflowmetry, volumetry, thermometry, spectrophotometry) into a single integrated system that collects all diagnostic data during one urination event, maximizing information gain while minimizing time and patient burden.

Inventive Principle:
Principle #5Merging (Combining)
