Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor assemblies with electrodes are integrated into the base plate to detect moisture propagation, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The sensor assembly is integrated directly into the base plate structure, combining the adhesive layer, electrodes, and monitoring functions into a single unified component. This merging approach enables moisture detection capability while maintaining a compact design that does not significantly increase overall device complexity
Solution Approach 2:
The base plate serves multiple functions: it provides structural support, adheres to the skin, and incorporates sensor capabilities for detecting moisture propagation. The adhesive layer itself serves dual purposes as both the bonding medium and the sensing medium, eliminating the need for separate sensor components
2Reliability
If real-time monitoring of adhesive performance is implemented, then reliability is improved, but use of energy increases
Solution Approach 1:
The monitoring system operates by periodically measuring capacitance changes between electrodes rather than continuous monitoring. This periodic measurement approach provides reliable detection of moisture propagation while minimizing energy consumption by keeping the system in a low-power state between measurements
Solution Approach 2:
The adhesive material itself serves as the sensing medium, utilizing its inherent dielectric properties to detect moisture. The system leverages the natural physical changes in the adhesive when exposed to moisture, eliminating the need for additional active sensing components that would consume energy
