Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing multimedia electronic devices are used, then basic display and input functions are provided, but skin moisture level information cannot be sensed or displayed
Solution Approach 1:
The input sensor is designed to perform multiple functions: it can detect both touch input operations and skin moisture levels using the same sensing structure. This allows the display device to provide both conventional touch functionality and biometric sensing capability without adding separate dedicated sensors, thereby improving versatility while controlling device complexity
2Adaptability or versatility
If skin moisture level sensing is added to display devices, then biometric information capability is improved, but device complexity increases
Solution Approach 1:
The input sensor serves dual purposes by detecting both touch operations and skin moisture levels through the same sensing mechanism, eliminating the need for separate biometric sensors and reducing overall system complexity
Solution Approach 2:
The readout circuit distinguishes between touch input and moisture level measurement by analyzing different electrical parameters from the input sensor. By changing the measurement mode and interpreting different signal characteristics, the system can extract both touch position information and skin moisture level data from the same sensor without requiring additional hardware
