Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional touch screen interaction is used, then the device can sense finger operations, but it cannot determine the position and type of external electronic objects placed on the screen
Solution Approach 1:
The touch screen is divided into multiple recognition regions, each corresponding to a specific coil antenna. By segmenting the detection area into discrete zones, the system can identify which specific region contains an electronic object, thereby enabling position detection while maintaining system simplicity
Solution Approach 2:
Coil antennas are introduced as intermediary components between the touch screen and the electronic objects. These coils generate magnetic fields that interact with electronic objects containing conductive materials, enabling indirect detection of object position and type without requiring direct contact or complex sensors
2Measurement precision
If coil antennas are added behind the touch screen to detect electronic tags, then position recognition is enabled, but device complexity increases
Solution Approach 1:
The coil antennas serve multiple functions: they generate magnetic fields for detecting electronic objects, determine the position of detected objects, and identify the type of electronic object. This multi-functionality reduces the need for separate detection systems, thereby limiting the increase in device complexity
Solution Approach 2:
The system detects changes in magnetic field parameters (such as field strength, phase, or frequency) when electronic objects are present. By monitoring these parameter changes, the system can infer object position and type without requiring complex hardware, thus balancing detection capability with device simplicity
