Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display devices are interconnected through home network to share video information, then content sharing capability is improved, but device complexity increases making it difficult to recognize and manage devices
Solution Approach 1:
The patent introduces an access point as an intermediary device that centralizes the management of multiple display devices. The access point collects RSSI information from all connected display devices and provides this information to the user through a user device interface, thereby mediating between the complex network of display devices and the user. This resolves the contradiction by maintaining content sharing capability while reducing device management complexity through centralized mediation.
Solution Approach 2:
The patent replaces manual device identification and management mechanisms with automated wireless signal-based detection. Instead of requiring users to manually configure or identify devices through complex network settings, the system automatically detects display devices using RSSI (Received Signal Strength Indicator) measurements and presents them in an intuitive interface sorted by signal strength. This substitution of automated electronic detection for manual mechanical configuration resolves the contradiction between content sharing capability and device management complexity.
2Ease of operation
If display devices are identified without location information, then device recognition is simplified, but user ability to locate and select specific devices deteriorates
Solution Approach 1:
The patent uses visual differentiation through color coding and graphical representation to convey location information. Display devices are represented with visual indicators that show their relative positions and signal strengths, allowing users to quickly identify and locate specific devices without complex text-based configuration. This visual encoding maintains ease of operation while preserving location information.
Solution Approach 2:
The patent adds a spatial dimension to device identification by using RSSI-based distance estimation. Instead of simply listing devices alphabetically or by ID, the system arranges devices in a spatial representation that reflects their physical locations relative to the access point. This dimensional transformation preserves location information while maintaining ease of operation through intuitive visual display.
3Measurement precision
If RSSI information is used to determine device distance, then location accuracy is improved, but measurement precision requirements increase
Solution Approach 1:
The patent implements self-service measurement where each display device autonomously transmits its RSSI information to the access point without requiring external measurement equipment or complex calibration procedures. The access point automatically collects and processes this information, and the user device automatically sorts and displays devices based on signal strength. This self-service approach improves location accuracy while avoiding the complexity of manual measurement systems.
Solution Approach 2:
The patent makes the existing wireless communication infrastructure multi-functional by using the same Wi-Fi or wireless connection that enables content sharing also for location detection and device identification. The RSSI information, already inherent in wireless communication protocols, is repurposed for spatial awareness and device management. This universal use of existing communication capabilities improves measurement precision without adding separate measurement systems or complexity.
