Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive voltage or current of functional modules is increased to improve signal quality and display performance, then the interference immunity of functional modules is improved, but the interference generated to the communication module increases
Solution Approach 1:
The patent implements dynamic adjustment of drive voltage or current for functional modules based on real-time communication states. The terminal device monitors communication parameters and adaptively changes the drive strength of functional modules to balance interference immunity and interference generation, resolving the contradiction between maintaining signal quality and reducing electromagnetic interference.
Solution Approach 2:
The patent changes the drive voltage or current parameters of functional modules according to communication states. By adjusting these electrical parameters dynamically, the system optimizes the balance between interference immunity (needing higher drive strength) and interference reduction (needing lower drive strength), thereby resolving the technical contradiction.
2Object-generated harmful factors
If the drive voltage or current of functional modules is decreased to reduce interference to the communication module, then the interference to communication module is reduced, but the interference immunity of functional modules deteriorates
Solution Approach 1:
The system dynamically adjusts drive strength based on communication requirements. When communication quality is good, drive voltage/current is reduced to minimize interference. When communication conditions deteriorate, drive strength is increased to maintain functional module performance, thus dynamically balancing interference reduction and immunity maintenance.
Solution Approach 2:
The terminal device performs preliminary assessment of communication states and proactively adjusts drive parameters before interference problems occur. By monitoring communication parameters in advance and preemptively adjusting functional module drive strength, the system prevents both excessive interference and insufficient immunity.
3Reliability
If the drive voltage or current is continuously adjusted to optimize both interference reduction and immunity, then the user experience is improved, but the system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the terminal device continuously monitors communication states and adjusts drive parameters accordingly. The communication module provides feedback on signal quality, and the processing unit uses this feedback to automatically adjust functional module drive strength, creating a closed-loop control system that improves user experience while managing complexity through automation.
Solution Approach 2:
The system performs self-adjustment of drive parameters without requiring external intervention. The terminal device autonomously monitors its own communication state and regulates functional module drive strength internally, enabling the system to optimize performance and resolve interference issues automatically, thereby improving user experience without proportionally increasing operational complexity.

AI summary
Disclosed is a signal processing method for regulating interference and interference immunity in a terminal device and a related apparatus. A terminal device obtains a state factor used for reflecting a communication state of a communication module and a usage state of a functional module. The terminal device down-regulates the source drive voltage or the source drive current when a frequency division frequency or frequency multiplication frequency of a signal transmitted on the signal line falls within a working frequency range. The terminal device up-regulates the source drive voltage or source drive current when a voltage amplitude of an electromagnetic wave component that is of an electromagnetic wave radiated by the communication module and that is coupled to the signal line is greater than a threshold. In this way, phenomena such as dropped calls and blurry screens can be mitigated, optimizing the user experience.
