Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional RF cellular networks are used to deliver data in densely populated areas, then coverage is provided, but the networks become overwhelmed and cannot efficiently deliver high-speed data
Solution Approach 1:
The patent replaces the traditional RF (radio frequency) electromagnetic wave transmission system with an optical transmission system using visible or infrared light. This substitution enables high-speed data transmission through light-based communication channels (such as Li-Fi technology), avoiding the congestion and interference problems inherent in RF networks, especially in densely populated areas like stadiums and urban environments.
Solution Approach 2:
The invention changes the fundamental transmission parameter from radio frequency electromagnetic waves to optical frequencies (visible or infrared light). This parameter change allows for vastly higher bandwidth and data transmission speeds, as optical frequencies operate at much higher carrier frequencies than RF, enabling gigabit-class data rates even in crowded environments where RF networks fail.
2Productivity
If optical transmitters broadcast encoded media streams in light emissions, then high-speed data transmission is achieved, but the system complexity increases with multiple access points and receiver units
Solution Approach 1:
The patent designs the optical receiver unit to be a universal device that can receive and decode light emissions from any of the multiple optical access points in the system. The receiver incorporates functionality to detect, demodulate, and process optical signals, converting them into electrical signals that can be displayed on connected devices. This multi-functional design simplifies the overall system architecture by using standardized receiver units that work with any transmitter in the network.
Solution Approach 2:
The invention introduces an optical receiver unit as an intermediary device between the optical transmitters and the end-user display devices. This intermediary converts the optical signals into electrical signals that can be processed by standard electronics, bridging the gap between the optical communication infrastructure and conventional display devices, thereby simplifying integration and system management.
3Productivity
If portable optical receiver units are used to capture light emissions, then high-speed data reception is enabled, but the need for precise alignment and mounting increases operational complexity
Solution Approach 1:
The patent incorporates dynamic adjustment capabilities in the optical receiver unit, allowing the optical detector to be positioned and oriented dynamically to track and maintain alignment with the light source. This may include motorized adjustment mechanisms or flexible mounting structures that enable the receiver to adapt to different viewing angles and distances, thereby maintaining optimal reception performance without requiring precise static alignment during installation.
