Advanced hygienic excreta system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Western toilet seats pose health risks and hygiene challenges, particularly for elderly and disabled individuals, due to the need for the Valsalva Maneuver during bowel movements, inadequate support for perineal cleaning, and potential contamination of vaginal and urethral areas during bidet use, as well as accommodating larger body sizes and reduced flexibility.
Innovation Solution
An advanced hygienic excreta system with a frame, rear and front handle assemblies, a seat with adjustable positions, and a footrest that can be elevated to support the user's feet and legs, reducing pressure on the rectum and allowing easier cleaning, featuring a motorized system for actuating the seat, footrest, and armrest to facilitate a safer and more comfortable bowel movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional Western toilet seat is used, then the structure is simple and easy to manufacture, but it causes health risks due to the Valsalva Maneuver and inadequate support for proper bowel movement
Solution Approach 1:
The patent applies dynamics by making the toilet seat adjustable in height and angle. The seat can be elevated to reduce knee strain and tilted to optimize the bowel movement angle, transforming a static structure into a dynamic one that adapts to user needs and reduces health risks
Solution Approach 2:
The toilet seat is segmented into multiple adjustable components including height adjustment mechanism, angle adjustment mechanism, and footrest. This segmentation allows each component to be optimized independently for health safety while managing overall system complexity
2Ease of operation
If the toilet seat is elevated to support feet and knees, then knee and back health is improved, but the device complexity increases
Solution Approach 1:
The footrest is designed as a dynamic component that can be adjusted to different heights and angles. This allows users to optimize knee and back comfort according to their specific needs, transforming a fixed structure into an adaptable one that improves ease of operation
3Ease of operation
If the seat is tilted to raise genitals above rectum, then hygiene is improved, but the device complexity increases
Solution Approach 1:
The seat incorporates an angle adjustment mechanism that dynamically tilts the seat surface to raise the genitals above the rectum. This dynamic positioning improves perineal cleaning accessibility by creating optimal anatomical alignment, while the mechanism itself manages the added structural complexity
4Ease of operation
If bidet water source is used for cleaning, then hygiene is improved, but there is risk of contaminating vagina and urethra
Solution Approach 1:
The patent introduces an intermediary positioning mechanism that tilts the seat to raise the genitals above the rectum. This intermediary anatomical positioning acts as a physical barrier that prevents bidet water from flowing forward into the vagina and urethra, thereby eliminating the contamination risk while maintaining cleaning effectiveness

AI summary
An accessory for an advanced hygienic excreta system comprising a base disposed around a bowl having a retracted position and an operational position; a seat having a convex surface configured to position a user's rectum below a user's knees when a user is seated on the seat and the seat is in a seated position; a footrest assembly having a footrest wherein the footrest is configured to be received into the base and to extend away from the base to support feet and legs of the user when the user is in a seated position; and, a controller carried by the base and connected to a motor set connected to the seat, footrest assembly and arm rest assembly and configured to receive input from an input device and actuate the motor set to extend and retract the seat, footrest, and arm rest.
