Vision-Guided Bidet Nozzle Adjustment for User Anatomy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern bidets do not provide an optimal cleaning experience for users of different sizes, shapes, and genders due to preset water direction settings, leading to cumbersome manual adjustments and potential accidents, and existing technologies like U.S. Pat. No. 5,201,080 suffer from limitations such as difficulty in detecting users with darker skin tones, obese individuals, and those with moles or hair, which complicates accurate orifice detection.
Innovation Solution
An electronic bidet system equipped with internal cameras and object recognition technology that captures images or videos of the user's genital and anal regions to identify types, sizes, shapes, and positions of orifices, automatically adjusting fluid and air nozzle directions based on user anatomy and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bidets use preset fixed nozzle directions and settings, then the device structure remains simple and easy to manufacture, but the cleaning effectiveness deteriorates for users of different sizes, shapes, and genders
Solution Approach 1:
The bidet system automatically performs user identification, anatomical analysis, and nozzle configuration without manual intervention. The camera captures images, the processor analyzes anatomical features, and the system self-adjusts nozzle positions and parameters, eliminating the need for users to manually program settings while achieving personalized cleaning
Solution Approach 2:
The patent replaces manual mechanical adjustment mechanisms with an automated optical-electronic system. Instead of requiring users to physically move nozzles or adjust dials, the system uses cameras to capture images, processors to analyze anatomy, and automated actuators to position nozzles, substituting mechanical user interaction with electronic automation
2Ease of operation
If bidets require manual adjustment of nozzle direction, then users can customize settings for their needs, but the ease of operation deteriorates due to cumbersome adjustment processes and potential embarrassing accidents
Solution Approach 1:
The system performs self-positioning by automatically capturing images of the user's anatomy, analyzing the data to determine optimal nozzle locations, and autonomously adjusting nozzle positions without user intervention, eliminating both the ease of manual adjustment and the risk of misadjustment
Solution Approach 2:
The system uses camera-based visual feedback to continuously monitor user position and anatomical features, processes this information to determine optimal nozzle settings, and adjusts nozzles accordingly, creating a closed-loop control system that ensures precise positioning adapted to each user's specific anatomy
3Measurement precision
If bidets use simplified detection methods like color or edge detection, then the device complexity remains low, but the measurement precision deteriorates for users with varying skin tones, body types, or anatomical conditions
Solution Approach 1:
The system transforms the detection approach by capturing multiple image parameters (color, texture, shape, position) and using advanced processing to extract anatomical features, changing from simple single-parameter detection to multi-parameter analysis that adapts to various skin tones and body types
Solution Approach 2:
The patent replaces simple optical detection mechanisms with a sophisticated image processing system that uses cameras, processors, and software algorithms to analyze anatomical features, substituting basic optical detection with electronic image analysis capable of handling diverse user characteristics
Data Source
AI summary
An electronic bidet system that uses one or more internal cameras to capture one or more images or video of a user as he or she sits on the bidet prior to use. The images or video are analyzed using object recognition technology to identify and segment/bound the types, sizes, shapes, and positions of the lower body orifices, and conditions (e.g. hemorrhoids), in the user's genital and rectal areas. Based on these analyzed images or video, the system automatically adjusts the bidet settings for the specific conditions (e.g. hemorrhoids) and types of orifices, locations of orifices, sizes of orifices, shapes of orifices, gender, body type, and weight of the user.
