Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first antenna transmits wireless signals with high power to ensure reliable communication, then communication reliability is improved, but wireless reception performance of the second antenna deteriorates due to interference
Solution Approach 1:
The patent implements dynamic transmission power adjustment where the processor continuously monitors the reception status of the second antenna and adjusts the transmission power of the first antenna in real-time. When the second antenna is actively receiving signals, the processor reduces the first antenna's transmission power to minimize interference, thereby maintaining communication reliability while protecting reception performance
Solution Approach 2:
The patent changes the transmission power parameter of the first antenna based on the operational state of the second antenna. By dynamically modifying this key parameter, the system resolves the contradiction between maintaining high transmission power for reliability and reducing interference for stable reception of the second antenna
2Productivity
If the first antenna transmits information frequently to ensure data synchronization, then communication efficiency is improved, but wireless reception performance of the second antenna deteriorates
Solution Approach 1:
The patent implements periodic transmission of information by the first antenna, controlled by the processor based on the reception status of the second antenna. Instead of continuous transmission, the system uses timed intervals and conditional triggering to send information only when necessary, reducing interference while maintaining synchronization efficiency
Solution Approach 2:
The processor monitors the reception status of the second antenna and uses this feedback to control the transmission behavior of the first antenna. This closed-loop control ensures that transmission frequency is optimized based on actual reception conditions, balancing communication efficiency with reception stability

AI summary
A communication device and an image display apparatus including the same are disclosed. A communication device of an embodiment of the present disclosure includes a first antenna and a second antenna to receive or transmit a wireless signal of a first and a second communication standard, respectively, and a processor to receive and process a signal or to transmit a processed signal, wherein, in case in which the second antenna receives a wireless signal while the first antenna wirelessly receives first data and wirelessly transmits information related to the first data with a first power, the processor is configured to wirelessly transmit the information related to the first data with a second power lower than the first power. Accordingly, wireless reception performance can be stably secured during wireless communication based on a plurality of communication standards.
