Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-precision equipment is used to set electrodes on the inspection portion, then the manufacturing precision is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies preliminary action by pre-forming positioning structures (protrusions and recesses) on the substrate and electrode elements before assembly. The substrate includes positioning protrusions that engage with positioning recesses on the electrode, ensuring accurate positioning is built into the components themselves rather than requiring complex external positioning equipment during manufacturing.
Solution Approach 2:
The patent implements self-service through self-positioning mechanisms where the electrode elements automatically locate themselves on the substrate via complementary geometric features (protrusions fitting into recesses). This self-positioning capability eliminates the need for high-precision external positioning equipment, as the components serve their own positioning function.
2Manufacturing precision
If multiple complex processes are used to manufacture the test strip, then the manufacturing precision is improved, but the productivity decreases and manufacturing cost increases
Solution Approach 1:
The patent merges multiple manufacturing steps into integrated processes. The electrode element is designed as a single integrated component that combines the electrode functional layer, insulation layer, and positioning features. This allows multiple functions (conduction, insulation, positioning) to be achieved in one manufacturing step rather than requiring separate processes for each feature.
Solution Approach 2:
The substrate serves multiple functions simultaneously: it provides mechanical support, electrical insulation, fluid distribution channels, and positioning features for electrode alignment. This multi-functionality reduces the number of separate components and assembly steps needed, thereby improving productivity while maintaining precision.
3Manufacturing precision
If multiple complex processes are used to manufacture the test strip, then the manufacturing precision is improved, but the manufacturing cost increases
Solution Approach 1:
The patent applies preliminary action by pre-forming positioning protrusions and recesses during standard manufacturing processes, so that precise alignment features are built into the components before assembly. This eliminates the need for expensive post-assembly adjustment equipment or processes.
Solution Approach 2:
The patent replaces complex mechanical positioning systems with simple geometric interlocking features (protrusions and recesses). Instead of using precision mechanical fixtures or adjustment mechanisms during assembly, the design relies on straightforward geometric compatibility that can be manufactured using conventional, low-cost processes.

AI summary
The present invention relates a setting method for a conducting element of an electrochemical test strip and electrochemical test strip thereof. An inspection body is formed by injection molding polymer plastic materials to coat with the plurality of conducting elements, and an external contact surface on an information outputting end of the conducting element is exposed from an inspection slot of the inspection body, so that the information outputting end of the conducting element is extended from the inspection body. Eventually, the information outputting end is bent to fix on a surface of the inspection body. The present invention is not complex and has more precision and convenience, and the manufacturing cost can be reduced efficiently, so that wide application can be expected in the near future.
