Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wired optical line connection is used for high-speed communication in collective housing, then communication speed is improved, but installation complexity increases due to requiring holes in walls
Solution Approach 1:
The patent replaces the mechanical drilling and wiring system with an optical wireless communication system using millimeter waves. The radio wave refracting plate enables the radio waves to bend around obstacles and enter indoor spaces without physical connections, eliminating the need for wall holes and mechanical installation while maintaining high-speed communication capabilities
Solution Approach 2:
The radio wave refracting plate serves as an intermediary device that receives millimeter waves from the base station, refracts them at a predetermined angle, and directs them into indoor spaces. This mediator enables communication coverage in areas with poor base station visibility without requiring direct line-of-sight or physical wiring
2Ease of manufacture
If FWA utilizing public LTE is used, then installation ease is improved, but communication reliability deteriorates when visibility from base station is poor
Solution Approach 1:
The radio wave refracting plate acts as an intermediary that captures millimeter waves from the base station and refracts them into indoor spaces with poor visibility. This mediator extends the coverage area and improves communication reliability in locations that would otherwise be out-of-coverage, while maintaining the installation simplicity of wireless systems
Solution Approach 2:
The system utilizes millimeter wave frequencies (higher frequency range) compared to traditional LTE frequencies. The radio wave refracting plate is specifically designed to refract these high-frequency waves at predetermined angles, enabling the waves to penetrate and propagate into indoor environments more effectively, thereby improving coverage and reliability
3Quantity of substance
If 5G of 28 GHz band is used for large-capacity communication, then communication capacity is improved, but coverage area deteriorates due to poor visibility requirements
Solution Approach 1:
The radio wave refracting plate introduces a new dimensional aspect to millimeter wave propagation by enabling controlled refraction at predetermined angles. This allows the communication system to reach indoor spaces and areas with poor visibility that would otherwise be inaccessible, significantly expanding the coverage area while maintaining the high capacity benefits of 28 GHz band communication
