Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If shielding members are added to reduce signal noise, then signal-noise ratio is improved, but device complexity increases
Solution Approach 1:
The detection device is segmented into multiple independent pixel-type electrodes arranged in a matrix, with each electrode having separate signal processing circuits. This segmentation allows individual signal processing for each electrode, improving signal separation and reducing noise without requiring additional shielding members, thus maintaining device simplicity while improving measurement precision.
2Area of stationary object
If multiple electrodes detect signals simultaneously at different locations, then detection coverage is improved, but signal separation becomes difficult
Solution Approach 1:
The detection device divides the detection area into multiple pixel-type electrodes arranged in a matrix, with each electrode independently detecting signals from its specific region. Each electrode is connected to separate anode and cathode wirings with dedicated signal processing circuits, enabling clear separation and identification of signals from different locations simultaneously, thus improving both detection coverage and signal separation accuracy.
Solution Approach 2:
The patent introduces intermediate connection structures including connection pads and wiring layers that act as intermediaries between the electrodes and external circuits. These intermediaries facilitate organized signal routing from multiple electrodes, enabling clear signal separation and identification even when multiple signals occur simultaneously at different locations.
