Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wireless communication methods (Bluetooth, Wi-Fi) are used to connect personal devices to virtual meetings, then device connectivity is achieved, but the process becomes complex and prone to radio interference
Solution Approach 1:
The patent replaces electromagnetic radio wave-based communication (Bluetooth, Wi-Fi) with light-based communication (visible light or infrared). This substitution eliminates radio interference issues and simplifies the connection process by using light sensors in personal devices to detect and decode light patterns emitted by display devices, automatically establishing communication without complex pairing procedures.
2Ease of operation
If multiple setup steps are required for device connection, then connection can be established, but user time and effort increase
Solution Approach 1:
The system performs preliminary actions by having the display device continuously emit encoded information in light patterns that personal devices can detect. When a personal device enters the vicinity, it automatically detects the light pattern and extracts connection information without requiring user initiation of pairing steps, thereby eliminating setup time and effort.
Solution Approach 2:
The connection establishment process is made self-service by enabling personal devices to automatically detect light patterns, decode encoded information, and initiate communication protocols without user intervention. The system self-configures the connection based on the detected light pattern, eliminating the need for manual pairing steps.
3Adaptability or versatility
If radio frequency communication is used, then wireless connectivity is achieved, but radio interference limits functionality
Solution Approach 1:
The patent substitutes radio frequency electromagnetic waves with optical electromagnetic waves (visible light or infrared). This substitution removes the device from the crowded radio frequency spectrum, eliminating interference with other wireless devices and enabling reliable communication in environments with high radio frequency activity.
