Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the discharge circuit discharges the voltage stored in the capacitor of the power stage, then the voltage of the external electronic device drops to less than or equal to a designated voltage, but the discharge time is slow and the reset operation takes a long time
Solution Approach 1:
The discharge process is divided into multiple discrete discharge operations. The processor controls the discharge circuit to perform sequential discharges, where each discharge operation reduces the voltage by a specific amount. This segmentation allows the system to achieve complete discharge faster by breaking down the continuous discharge process into manageable steps, thereby reducing total discharge time while ensuring the voltage reaches the designated level for reliable communication connection.
Solution Approach 2:
The discharge circuit performs preliminary discharge operations before the communication connection is established. By pre-discharging the capacitor to reduce the voltage to an appropriate level before data transmission begins, the system prevents voltage-related malfunctions during communication while minimizing the time the external electronic device remains in a reset state. This preliminary action ensures communication reliability without prolonging the reset duration.
2Loss of time
If the external electronic device is reconnected before the voltage drops to less than or equal to a designated voltage, then communication connection can be established faster, but a malfunction of the external electronic device may occur
Solution Approach 1:
The processor monitors the voltage level of the external electronic device during the discharge process and uses this feedback information to control when to establish the communication connection. The system continuously checks whether the voltage has dropped to the designated level or below, and only enables communication connection when the voltage condition is satisfied. This feedback mechanism ensures that reconnection occurs at the optimal moment, preventing malfunctions while minimizing the waiting time for communication establishment.
