Solution Overview

Problem

Current urodynamic examinations for urinary and digestive health are invasive, painful, and lack effective, objective monitoring for urine and excrement analysis, which are crucial for early detection of urinary and digestive tract tumors, hindered by the unpleasant nature of the samples.

Innovation Solution

A closestool type urine and excrement detection robot equipped with an intelligent moving module, interactive module, height adjustment, user identification, detection modules, and an IoT system for autonomous operation, data processing, and security, enabling convenient and non-invasive monitoring of urination and defecation behaviors and components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional urodynamic examination is used, then urinary function can be examined, but the examination process is long and causes unbearable pain

Engineering Contradiction:

Improveurinary function examination accuracyVSAvoidexamination comfort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the invasive mechanical catheter-based urodynamic examination system with a non-invasive robotic detection system that uses sensors and imaging technology to monitor urinary function, thereby eliminating pain while maintaining examination capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The robotic detection device enables patients to perform urinary monitoring independently at home without requiring hospital visits or professional operator assistance, making the examination process convenient and pain-free

Inventive Principle:

Principle #25Self-service

2Reliability

If urine and excrement detection is performed for early tumor screening, then early detection effectiveness is improved, but the dirty and smelly nature of samples reduces user cooperation

Engineering Contradiction:

Improveearly tumor screening effectivenessVSAvoiduser cooperation willingness

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a robotic detection device as an intermediary between the user and the urine/excrement samples, allowing automated sample analysis without direct user contact with the unpleasant samples, thereby maintaining detection effectiveness while improving user acceptance

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces manual sample handling and analysis with automated robotic detection using optical and chemical sensors, eliminating the need for users to directly interact with dirty and smelly samples while preserving early tumor screening capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If manual urine and excrement analysis is performed, then detection can be conducted, but the process requires hospital visits and is inconvenient

Engineering Contradiction:

Improvedetection accuracyVSAvoiddetection convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The robotic detection device enables patients to perform urinary and digestive health monitoring independently at home, eliminating the need for hospital visits while maintaining reliable detection accuracy through automated analysis

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent integrates multiple detection functions (urine analysis, excrement analysis, early tumor screening) into a single robotic device that can be used at home, providing comprehensive health monitoring convenience without sacrificing detection reliability

Inventive Principle:

Principle #6Universality (Multi-functionality)
