Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex structural configuration is used to ensure effective excrement detection and cleaning, then cleaning effectiveness is improved, but device complexity increases and makes the device bulky and difficult to clean
Solution Approach 1:
The device is divided into two main modular components: a hard body containing the control unit, sensors, and flushing mechanisms, and a soft cup body that can be detached for cleaning. This segmentation allows the cleaning components to be separated from the control components, simplifying the overall structure while maintaining cleaning effectiveness.
Solution Approach 2:
The cup body, which comes into contact with excrement and requires frequent cleaning, is extracted as a separate detachable component from the main body. This allows the cleaning mechanisms to be simplified while the cup body can be easily removed and cleaned independently, reducing the complexity of the integrated structure.
2Reliability
If holes are made in the mattress to connect cleaning device lines, then excrement detection and cleaning capability is improved, but the mattress structure is modified and complicates device installation
Solution Approach 1:
The device is designed to function on conventional beds without requiring specialized mattresses with pre-made holes. The control unit and sensors are positioned to detect excrement through the mattress surface or using proximity sensing, making the device universally applicable to standard bedding configurations.
Solution Approach 2:
The device uses an intermediary sensing mechanism that can detect excrement without direct contact or mattress modification. The control unit processes signals from sensors that detect excrement presence through non-invasive means, eliminating the need for physical holes in the mattress.
3Stability of the object's composition
If a rigid structure is used for the cleaning device body, then structural stability is improved, but wearability and flexibility are reduced
Solution Approach 1:
The device employs different material properties in different regions: the body containing electronics and control mechanisms is made of hard material for structural stability and protection of internal components, while the cup body that contacts the patient is made of soft, flexible material for comfort and wearability. This local differentiation of material properties resolves the contradiction between stability and flexibility.
Solution Approach 2:
The device combines hard and soft materials in a composite structure. The hard body provides structural support and houses electronic components, while the soft cup body provides patient comfort and flexibility. This composite construction allows the device to simultaneously achieve structural stability and wearability.
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 device provides a simpler, more efficient, and user-friendly excrement cleaning solution by increasing the flushing range and improving cleaning effectiveness, while also enhancing wearability and flexibility, thus addressing the limitations of previous devices.
Implementation Method 1
the hardness of the tube base and the nozzle is greater than the hardness of the hose, which allows water pressure through the tube base to the hose to shake the nozzle for increasing cleaning range
