Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If antenna modules operate continuously in high-frequency bands to maintain communication performance, then data transmission rate is improved, but temperature increases leading to performance deterioration
Solution Approach 1:
The patent implements periodic switching between multiple antenna modules, where each module operates for a certain period then switches to another module. This periodic operation allows individual modules to cool down during idle periods while maintaining continuous communication service through the other modules, thus resolving the contradiction between continuous operation for high data rate and temperature control for performance maintenance
Solution Approach 2:
The patent divides the antenna system into multiple separate antenna modules, each capable of independent operation. By segmenting the overall antenna function across multiple modules, the system can rotate usage among them, preventing any single module from overheating while maintaining the required data transmission performance through the collective capability of all modules
2Temperature
If multiple antenna modules are used to manage temperature, then temperature control is improved, but device complexity increases
Solution Approach 1:
The patent designs multiple antenna modules with identical or similar functional capabilities, where each module can perform the same communication functions. This universality allows the system to switch between modules without requiring complex reconfiguration, as each module is a interchangeable unit with the same interface and functionality, thus managing temperature effectively while minimizing the increase in system complexity

AI summary
The present disclosure relates to a device for activating a radio frequency (RF) module which is to be used efficiently in an electronic device that operates a plurality of RF modules (or antenna modules) in a wireless communication system, and to a method for controlling same. To this end, the electronic device checks the temperatures of the plurality of antenna modules using a first frequency band, and identifies candidate antenna modules in consideration of the temperatures of the plurality of antenna modules. The electronic device selects a serving antenna module from among the candidate antenna modules so that an available temperature state, in which the temperatures of the candidate antenna modules are lower than a threshold temperature, is maintained, and transmits and receives a signal using the first frequency band in the serving antenna module. The candidate antenna modules may include antenna modules which support communication performance of a threshold level or higher.
