Engineering Contradiction Analysis
1Measurement precision
If a temperature detection module is integrated into the MEMS microphone, then the ability to detect ambient temperature is improved, but the device complexity increases
Solution Approach 1:
The temperature detection module is integrated into the ASIC chip that is already part of the MEMS microphone assembly. The ASIC chip hosts multiple functional modules including signal processing, voltage regulation, and now temperature detection, merging multiple functions into a single integrated circuit component. This approach adds temperature sensing capability while minimizing the increase in overall device complexity by utilizing existing chip real estate and shared infrastructure.

If the ASIC chip integrates multiple modules including temperature detection, then the adaptability to environment is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The ASIC chip is designed as a multi-functional integrated circuit that handles signal processing, power management, and environmental sensing (including temperature). By making the ASIC chip universal and multi-functional, the system achieves high environmental adaptability without proportionally increasing manufacturing complexity, as the same manufacturing process fabricates all functional modules on a single chip.
