Engineering Contradiction Analysis
1Use of energy by moving object
If conventional port state detection methods are used to identify multiple identical chips, then chip identification can be achieved, but the detection process is slow and consumes excessive power
Solution Approach 1:
The port state detection is segmented into multiple voltage threshold comparisons. The detection circuit divides the voltage range into multiple segments using different reference voltages, allowing the system to determine port state through sequential threshold comparisons rather than a single complex measurement, thereby reducing power consumption while maintaining accuracy
Solution Approach 2:
The invention changes the detection parameter from direct current measurement to voltage threshold comparison. By converting port state detection into voltage level comparisons against multiple reference thresholds, the system achieves faster detection speed and lower power consumption while maintaining reliable state identification
2Measurement precision
If complex detection processes are used to distinguish chip states, then detection accuracy can be improved, but the detection speed decreases and power consumption increases
Solution Approach 1:
The detection circuit performs preliminary voltage threshold comparisons using multiple reference voltages before final state determination. This preliminary action of comparing against predetermined voltage thresholds enables rapid elimination of impossible states, achieving both high precision and fast detection speed
Solution Approach 2:
The invention replaces complex mechanical or sequential detection processes with an electrical voltage comparison system. By using electrical potential differences and comparator circuits, the system achieves simultaneous multi-threshold evaluation, dramatically improving detection speed while maintaining precision
3Adaptability or versatility
If multiple identical chips are used in a communication terminal, then system functionality is enhanced, but the complexity of identifying and distinguishing each chip increases
Solution Approach 1:
The detection circuit is designed with universal reference voltage generation that can identify multiple identical chips using the same circuit architecture. Each chip can be configured with different port states, and the universal detection mechanism handles all identification tasks through standardized voltage threshold comparisons, enhancing adaptability without increasing system complexity
