Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radio-frequency communication is used to transfer information between physical objects and virtual environments, then information transfer can be achieved, but the user experience enrichment and real-time updating capability are limited
Solution Approach 1:
The patent replaces radio-frequency electromagnetic communication with visible light communication. By using modulated visible light from light sources (LEDs, lasers) to encode and transmit data, the system achieves higher bandwidth and real-time updating capability while enriching user experience through optical communication channels that were previously unavailable for this application.
Solution Approach 2:
The patent changes the communication parameter from radio frequency to visible light frequency. By modulating the intensity, frequency, or phase of visible light carriers, the system enables higher data transmission rates and real-time information exchange between physical objects and virtual environments, directly addressing the limitation of real-time updating capability.
2Productivity
If visible light communication is implemented between user devices and physical objects, then real-time information transfer and user experience enhancement are achieved, but device complexity increases
Solution Approach 1:
The patent leverages existing multi-functional components in user devices. Cameras and sensors that already exist for other purposes (photography, environmental sensing) are repurposed to detect modulated light signals. Similarly, light sources like LEDs and displays serve both their original functions and as communication transmitters, reducing the need for dedicated communication hardware and minimizing device complexity.
Solution Approach 2:
The system uses ambient light sources and existing device components to perform communication functions. The camera and sensors automatically detect and process light signals without requiring separate dedicated receivers, while light sources naturally emit modulated signals based on their operation, eliminating the need for additional specialized communication hardware.
