Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Toilets pose challenges for individuals with illnesses, injuries, severe obesity, disabilities, or advanced age due to balance issues and difficulty in cleaning oneself after use, and there is a need for a commode with enhanced cleaning capabilities, especially for those who require assistance.
Innovation Solution
An electronic commode system with artificial intelligence, computer vision, and spectroscopy software that automatically detects and cleans feces using a camera, fluid nozzles, and air dryers, adjusting their position in three dimensions to ensure thorough cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard toilet is used, then the basic function of waste disposal is achieved, but it poses safety risks and cleaning difficulties for individuals with illnesses, injuries, severe obesity, disabilities, or advanced age
Solution Approach 1:
The system uses AI-powered camera detection to automatically identify feces on the user's skin and controls fluid nozzles to self-adjust and clean the detected areas, eliminating the need for manual cleaning operations by the user
Solution Approach 2:
The patent replaces manual mechanical cleaning actions with an automated electronic system that uses computer vision, AI algorithms, and controlled fluid injection to perform cleaning functions
2Manufacturing precision
If bidet nozzles are used for cleaning, then cleaning effectiveness is improved, but the system complexity and difficulty of operation increase for disabled users
Solution Approach 1:
The bidet system automatically detects feces locations using AI camera analysis and self-adjusts nozzle positions and fluid ejection patterns without requiring user intervention or manual positioning
Solution Approach 2:
The system dynamically adjusts nozzle positions in three dimensions based on real-time detection of feces location and user anatomy, adapting the cleaning pattern to individual needs
3Ease of operation
If manual cleaning operations are performed, then cleaning can be achieved, but it is difficult for individuals with illnesses, injuries, severe obesity, disabilities, or advanced age
Solution Approach 1:
The system performs automatic detection and cleaning operations without requiring manual user actions, using AI-powered image analysis and automated fluid control to achieve both ease of operation and cleaning precision
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively identifies and cleans feces using absorption spectra analysis, ensuring complete sanitation and user independence by adapting to individual anatomical variations and conditions, improving hygiene and safety.
Implementation Method 1
the activated commode illuminates the genital, anal, and surrounding areas of the buttock regions of a user through the bowl opening with the light source with white light
Implementation Method 2
the camera captures a first plurality of images, or a first video, of the illuminated genital, anal, and surrounding areas of the buttock regions of the user
Implementation Method 3
analyzed with software to identify feces on the user by detecting the absorption spectra of bilirubin compared to skin of the user in white light
Data Source
AI summary
A free-standing electronic commode bidet system, a bidet system, and an electronic commode bidet system for insertion onto a wheelchair, all three systems using artificial intelligence and spectroscopy software incorporating fecal detection algorithms. The systems use one or more internal cameras, or other sensors, to capture one or more images of a user as he or she sits on the commode prior to use. The systems automatically detect feces on a user by detecting the absorption spectra of bilirubin, a biomarker of feces. The systems calculate the ratio of green or red light to blue light on an RGB light spectrum. In the presence of bilirubin, more blue light will be absorbed by feces, and the green and red light are not absorbed. Once feces are detected and located on the user, the systems activate one or more water sprays to clean the feces from the user.
