Bedridden Patient Excrement Care Robot with Motion Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional excrement treating apparatuses for bedridden patients are poorly designed, leading to usability issues due to difficulty in contact with the body's bends, resulting in leakage and discomfort, and fail to accommodate position changes, which can cause bedsores.
Innovation Solution
An excrement care robot with a body-fitted treating apparatus equipped with a sensor unit and motion analysis unit that measures and analyzes three-axis rotation angles to determine the patient's position and condition, enabling appropriate pressure distribution and preventing bedsores by integrating motion and condition analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the excrement treating apparatus is designed to focus only on excrement treatment function, then the excrement treatment capability is improved, but the usability and contact with body bends deteriorates
Solution Approach 1:
The excrement treating apparatus is designed to perform multiple functions: excrement treatment, motion analysis, and condition monitoring. The sensor unit and motion analysis unit are integrated into the apparatus, enabling it to not only treat excrement but also analyze the user's position and induce appropriate pressure distribution, thereby improving usability while maintaining excrement treatment capability
2Device complexity
If the excrement treating apparatus does not consider the user's body structure, then the device complexity is reduced, but the contact with body bends and leakage prevention deteriorates
Solution Approach 1:
The apparatus applies different properties to different parts of the body. The sensor unit is strategically placed to detect position changes in critical areas, and the pressure distribution is locally adjusted based on detected motion and body structure, improving leakage prevention without significantly increasing overall device complexity
3Stability of the object's composition
If the bedridden patient cannot change position while wearing the excrement treating apparatus, then the apparatus stability is improved, but bedsores occur due to prolonged pressure
Solution Approach 1:
The sensor unit continuously monitors the user's position and motion, providing feedback to the motion analysis unit. Based on this feedback, the system induces appropriate pressure distribution by adjusting the apparatus's pressure application points, enabling position changes without removing the apparatus, thus preventing bedsores while maintaining stability
4Ease of operation
If the excrement treating apparatus requires removal for position changes, then the contact with body is maintained, but the convenience and continuous treatment capability deteriorates
Solution Approach 1:
The apparatus performs self-adjustment based on sensor data and motion analysis. The system automatically induces appropriate pressure distribution and facilitates position changes without requiring user intervention or removal of the apparatus, maintaining both convenience and continuous treatment capability
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 excrement care robot effectively prevents leakage and bedsores by ensuring proper contact with the body and facilitating position changes, improving usability and comfort for bedridden patients.
Implementation Method 1
The sensor unit may include an inertial sensor that measures rotation angles with respect to a X (pitch) axis, a Y (roll) axis, and a Z (yaw) axis of the body
