Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple base stations are deployed to improve wireless communication coverage in production facilities, then communication quality is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces electromagnetic wave reflectors as intermediary devices to redirect and guide radio waves between base stations and mobile devices. These reflectors act as mediators that improve signal propagation without requiring additional base stations, thus maintaining communication quality while reducing system complexity
Solution Approach 2:
The patent employs meta-reflectors with adjustable reflection coefficients to dynamically control electromagnetic wave reflection characteristics. By changing the reflection parameters of existing infrastructure, the system optimizes wireless communication without adding more base stations, resolving the contradiction between communication quality and system complexity
2Area of stationary object
If electromagnetic wave reflectors are used to direct radio waves, then space usage is optimized, but manufacturing and installation complexity increases
Solution Approach 1:
The patent divides the electromagnetic wave reflector system into modular panels that can be independently manufactured and assembled. Each panel contains meta-reflectors with specific reflection characteristics, allowing flexible deployment and simplified installation while optimizing space usage in production facilities
Solution Approach 2:
The patent designs universal electromagnetic wave reflector panels that can be deployed in various configurations and locations within production facilities. These multi-functional panels serve both as electromagnetic wave guides and as space-efficient structural elements, reducing installation complexity while maximizing space utilization
