Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wireless connection approaches (Bluetooth, Wi-Fi) are used to connect personal devices to virtual meetings, then device connectivity is achieved, but the process requires multiple steps and is prone to radio interference
Solution Approach 1:
The patent replaces radio frequency-based wireless connection mechanisms (Bluetooth, Wi-Fi) with optical communication using visible light. The light emitter transmits meeting identification information through light patterns that the personal device's camera detects, eliminating radio interference and simplifying the connection process to automatic detection and configuration.
2Ease of operation
If conventional wireless connection approaches are used, then device connectivity is achieved, but manual setup steps are required
Solution Approach 1:
The system performs preliminary actions by pre-configuring the light emitter with meeting identification information and parameters before the user arrives. When the user enters the physical space, the light pattern is automatically transmitted, and the personal device automatically detects and decodes the information, performing self-configuration without requiring manual user input or setup steps.
Solution Approach 2:
The personal device performs self-service by automatically detecting the light pattern, decoding the meeting identification information, and configuring itself to join the virtual meeting without user intervention. The device autonomously completes the connection process, eliminating manual setup steps and reducing setup time.
3Extent of automation
If light communications system is used, then automatic configuration is achieved, but light pattern detection and decoding complexity increases
Solution Approach 1:
The light emitter transmits information using periodic on/off patterns that encode meeting identification data. The personal device's camera captures these periodic light variations, and the processor decodes the binary information from the on/off sequence. This periodic encoding scheme simplifies the detection process compared to continuous modulation schemes.
