Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image recognition processing is used to identify a person, then personal information can be obtained, but an appreciable time is required for achieving the identification
Solution Approach 1:
The patent introduces RFID tags as an intermediary carrier of personal information. Instead of directly analyzing human features through image recognition, the robot reads pre-stored identification data from RFID tags worn by individuals. This intermediary approach enables rapid information acquisition without the time-consuming process of visual feature extraction and matching.
Solution Approach 2:
The patent replaces the mechanical/optical image recognition system with an electromagnetic field-based RFID reading system. The robot uses electromagnetic waves to communicate with RFID tags, obtaining personal information through radio frequency signals rather than through optical capture and computational image analysis, thereby significantly reducing identification time.
2Adaptability or versatility
If the robot has communication with a person, then personalized interaction can be achieved, but the robot must determine appropriate communication timing based on locomotion speed and distance
Solution Approach 1:
The patent implements preliminary action by having the robot acquire personal information from RFID tags before actual communication occurs. The robot also calculates predicted communication timing in advance based on current distance and locomotion speed, preparing communication content and selecting appropriate interaction modes before approaching the individual, thereby enabling smooth and context-appropriate communication.
Solution Approach 2:
The patent employs feedback mechanisms where the robot continuously monitors its own locomotion state and distance to the target person. Based on this real-time feedback, the robot dynamically adjusts communication timing predictions and modifies communication strategies to match the actual interaction context, ensuring appropriate personalization without excessive complexity.
