Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional electrochemical detection electrodes use a single detection structure design, then the manufacturing process is simple, but the ability to detect multiple types of substances simultaneously is limited

Engineering Contradiction:
Improvedetection capability for multiple substancesVSAvoidelectrode structure design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The electrode is divided into multiple independent detection regions, each with distinct detection structures (e.g., different geometric shapes, sizes, or material compositions) that can selectively detect different substances. This segmentation allows the electrode to simultaneously detect multiple analytes without cross-interference while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The electrode structure is designed to perform multiple detection functions within a single device. By integrating different detection structures that respond to various electrochemical parameters (current, voltage, impedance) for different substances, the electrode achieves multi-functionality, enabling simultaneous detection of multiple substance types without requiring separate electrodes for each analyte.

Inventive Principle:
Principle #6Universality (Multi-functionality)
