Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a device supports multiple frequency bands for communication, then communication compatibility and coverage are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent implements dynamic frequency band switching where the electronic device automatically selects between first and second frequency bands based on communication needs. The switching mechanism allows the device to adapt its operating frequency dynamically, supporting multiple bands without requiring permanent hardware configurations for each band, thus reducing overall device complexity while maintaining versatility.
Solution Approach 2:
The patent creates a universal communication mechanism that can operate across multiple frequency bands using a single integrated approach. The switching module and communication module work together to provide multi-band support through a unified system rather than separate dedicated hardware for each band, achieving multi-functionality without proportional increase in complexity.
2Adaptability or versatility
If a device supports multiple frequency bands for communication, then communication compatibility and coverage are improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic frequency band switching where the electronic device automatically selects between first and second frequency bands based on communication needs. The switching mechanism allows the device to adapt its operating frequency dynamically, supporting multiple bands without requiring permanent hardware configurations for each band, thus reducing overall device complexity while maintaining versatility.
Solution Approach 2:
The patent changes the operating frequency parameter dynamically based on communication requirements. By switching between different frequency bands (first frequency band and second frequency band) rather than operating continuously at all possible frequencies, the device optimizes power consumption while maintaining communication compatibility across different bands.
3Adaptability or versatility
If frequency band switching is implemented, then communication flexibility is improved, but control complexity increases
Solution Approach 1:
The patent implements an automatic switching mechanism where the electronic device autonomously selects between frequency bands based on pre-set conditions and communication needs. The switching module automatically manages frequency band transitions without requiring manual intervention or complex external control systems, reducing control complexity while maintaining communication flexibility.
Solution Approach 2:
The patent incorporates a switching module that monitors communication conditions and automatically adjusts frequency band selection based on feedback from the communication environment. This feedback mechanism enables flexible frequency band adaptation while simplifying control by using automated decision-making rather than complex manual control systems.

AI summary
An operation method of an electronic device includes determining whether a first communication module based on a first radio access technology (RAT) and a second communication module based on a second RAT operate in a connected state; determining whether a combination of a first band used by the first communication module and a second band used by the second communication module is a combination causing interference; and if the combination of the first band and the second band is a combination causing interference, transmitting a signal requesting to change one of the first band or the second band. The interference is caused by at least one transmission signal of the first RAT or at least one other signal derived from the at least one transmission signal.
