Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user manually inputs IP addresses and layout information to configure multi-display settings, then the display positions can be set, but the operation becomes complicated and input errors are likely to occur
Solution Approach 1:
The patent replaces manual mechanical input operations with automatic wireless detection and identification. The communication apparatus automatically detects nearby display apparatuses through wireless communication and acquires their identification information, eliminating the need for users to manually input IP addresses and layout data, thus reducing operational complexity while maintaining positioning accuracy
Solution Approach 2:
The system enables self-service configuration where the communication apparatus autonomously performs detection, identification, and position determination without requiring user intervention for data input. The apparatus automatically establishes wireless connections, retrieves identification information, and determines display positions based on detected signals
2Measurement precision
If test images are projected and captured to recognize layout relationships, then display positions can be determined, but the recognition may fail due to adverse environmental factors and projection system variations
Solution Approach 1:
The patent replaces optical-based test image projection and capture methods with wireless electromagnetic communication for position determination. By using wireless signals to directly acquire identification information from display apparatuses, the system eliminates reliability issues related to environmental lighting conditions, projection optical variations, and image capture quality
Solution Approach 2:
The patent introduces wireless communication as an intermediary mechanism between the communication apparatus and display apparatuses. This intermediary enables direct information exchange about identification and position data without requiring visual projection and capture, thereby improving reliability by bypassing environmental factors that affect optical methods
