Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual wound cleaning is performed by a medical professional, then flexibility and adaptability to the wound surface can be maintained, but consistent high-quality cleaning and uniform coverage are difficult to achieve
Solution Approach 1:
The system incorporates sensors (thermal imaging, hyperspectral, resistance sensors) that continuously monitor the wound surface and provide real-time feedback to the control device. This feedback loop enables the robotic system to automatically adjust cleaning parameters and maintain consistent high-quality cleaning across the entire wound surface, resolving the contradiction between manual flexibility and cleaning consistency.
Solution Approach 2:
The patent replaces the mechanical manual cleaning process with an automated robotic system controlled by computational algorithms. The robotic arm, guided by sensor data and control logic, performs cleaning operations with precise repeatability, eliminating the variability inherent in manual procedures while maintaining adaptability through programmable adjustment.
2Extent of automation
If robotic arm cleaning is used to achieve automated cleaning, then consistent coverage can be improved, but the inhomogeneous structure of wound surfaces results in unsatisfactory cleaning quality
Solution Approach 1:
The system employs multiple specialized sensors (thermal imaging for blood flow detection, hyperspectral for spectral signature analysis, resistance sensors for electrical property detection) that characterize different regions of the inhomogeneous wound surface. The control device uses this local quality information to selectively apply cleaning parameters to specific areas, enabling high-quality cleaning of complex surface structures.
Solution Approach 2:
The robotic system dynamically adjusts cleaning parameters (fluid pressure, flow rate, nozzle position) based on real-time sensor feedback from different wound regions. This parameter adaptation allows the automated system to handle the inhomogeneous structure effectively, maintaining high cleaning quality across varying surface conditions.
3Measurement precision
If multiple sensors are used to assess cleaning quality, then accurate real-time assessment can be achieved, but device complexity increases
Solution Approach 1:
The patent integrates multiple sensor types (thermal imaging, hyperspectral, resistance sensors, MEMS sensors) into a unified multi-functional assessment system. These sensors work together to provide comprehensive cleaning quality evaluation, with the control device processing data from all sensors to generate an overall assessment, thereby achieving high measurement precision while managing system complexity through integrated control.
