Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional electrode configurations are used, then manufacturing is simpler, but sensor initialization time is prolonged and measurement accuracy is reduced
Solution Approach 1:
The sensor electrode is divided into multiple discrete electrode elements (working electrode, reference electrode, counter electrode) arranged in a specific spatial configuration. This segmentation allows each electrode to perform its specific function independently, enabling faster hydration and initialization while maintaining manufacturing feasibility through modular assembly
Solution Approach 2:
The patent transitions from traditional planar electrode arrangements to a three-dimensional distributed electrode configuration where electrodes are positioned at different spatial locations and orientations. This dimensional change optimizes fluid flow patterns and hydration distribution, significantly reducing initialization time while the structured arrangement maintains manufacturing complexity at acceptable levels
2Measurement precision
If optimized electrode configurations are implemented, then measurement accuracy improves, but device complexity increases
Solution Approach 1:
Different regions of the sensor are assigned specific electrode types and configurations optimized for their local functions. The working electrode region is designed for analyte detection, the reference electrode region for stable potential maintenance, and the counter electrode region for current completion. This local optimization enhances measurement precision while the modular nature keeps overall device complexity manageable
Solution Approach 2:
The electrode configuration is designed to serve multiple functions simultaneously: the distributed electrodes enable accurate analyte measurement, provide stable reference potential, facilitate efficient current flow, and promote uniform hydration. This multi-functionality achieves high measurement precision without proportionally increasing device complexity
