Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If chemical and electronic components are connected mechanically, then the sensor can be assembled, but the assembly process becomes time-consuming and complex
Solution Approach 1:
The patent combines chemical sensing components and electronic components onto a single substrate, eliminating the need for mechanical connection and assembly between separate components. This integration directly resolves the technical contradiction by making the assembly process trivial (merging components) while eliminating assembly time loss.
2Reliability
If chemical and electronic components are connected mechanically, then the sensor can be assembled, but the mechanical interface becomes a potential failure point
Solution Approach 1:
By integrating chemical and electronic components on the same substrate with direct electrical connections, the patent eliminates mechanical interfaces entirely. This merging approach improves reliability by removing failure-prone mechanical connections while simplifying the overall device structure.
3Ease of manufacture
If the sensor is mounted to the circuit board before testing, then the device is complete, but factory calibration processing becomes complicated
Solution Approach 1:
The patent enables device-level testing to be performed before final mounting to the circuit board by integrating all necessary components on a single substrate. This preliminary testing capability allows factory calibration to be completed earlier in the manufacturing process, simplifying the overall calibration procedure and reducing manufacturing complexity.
