Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single CVCES treatment at a blindly or randomly selected voltage is applied, then the treatment can be implemented without complex analysis, but the electrochemical response becomes unpredictable and may not be optimal for biofilm disruption
Solution Approach 1:
The system performs a preliminary polarization scan before the actual CVCES treatment to characterize the implant's electrochemical properties. This preliminary analysis identifies the hydrogen evolution reaction threshold and alloy composition, enabling selection of an optimal treatment voltage that is tailored to the specific implant rather than using a blind or random voltage selection.
Solution Approach 2:
The system uses feedback from the polarization scan results to automatically adjust and determine the optimal CVCES treatment voltage. The processor analyzes the electrochemical indicators from the scan and feeds this information back into the voltage selection process, eliminating the need for blind voltage selection while ensuring reliable and predictable electrochemical response for biofilm disruption.
2Reliability
If autonomous detection of hydrogen evolution reaction threshold is implemented, then optimal voltage selection is precise and reliable, but the treatment system complexity increases
Solution Approach 1:
The polarization scan apparatus and processor are integrated into the existing CVCES treatment system, allowing the same system to perform both characterization (polarization scan) and treatment (CVCES) functions. This multi-functionality reduces the need for separate dedicated equipment, thereby limiting the increase in overall system complexity while maintaining accurate autonomous detection capabilities.
Solution Approach 2:
The system performs self-characterization by automatically conducting the polarization scan and analyzing its own electrochemical response to determine the hydrogen evolution reaction threshold and optimal treatment voltage. This self-service approach eliminates the need for external manual analysis or additional complex equipment, achieving reliable autonomous detection with minimal added system complexity.
