Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrodes are distributed on the same side of the sensor, then the sensor can perform electrochemical analysis, but the process difficulty and technical requirements increase
Solution Approach 1:
The patent transitions from a single-sided electrode arrangement to a double-sided electrode configuration, utilizing both faces of the sensor substrate to distribute electrodes. This dimensional change allows multiple electrodes to be arranged on opposite sides, reducing the crowding and complexity on any single side while maintaining electrochemical analysis capability.
2Ease of manufacture
If electrodes are distributed on two sides of the sensor, then the process difficulty of sensor production is reduced, but the fixing member becomes more complex and mounting difficulty increases
Solution Approach 1:
The fixing member is divided into distinct functional segments: a first fixing portion for securing the sensor substrate, a second fixing portion for positioning, and conductive path portions for electrical connection. This segmentation allows each portion to be optimized independently, simplifying the overall design and manufacturing of the fixing member while accommodating double-sided electrodes.
Solution Approach 2:
The patent introduces conductive path portions as intermediary elements that bridge the electrical connection between the double-sided electrodes and the external circuitry. These conductive paths are integrated into the fixing member structure, serving as both mechanical support and electrical conduit, thereby reducing the need for separate complex connection components.
3Reliability
If a fixing member with electric contacts on different sides is provided, then double-sided microelectrodes can be connected, but the complexity of the fixing member increases
Solution Approach 1:
The patent merges the mechanical fixing function and electrical connection function into a single integrated fixing member structure. The conductive path portions are built into the fixing member itself, eliminating the need for separate connection components. This integration reduces the number of parts and simplifies the overall device while maintaining reliable electrical connection to double-sided electrodes.
