Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID technology with wearable devices is implemented to provide immediate feedback and track interactions, then the interactive experience and feedback mechanism are improved, but the device complexity increases
Solution Approach 1:
The system is divided into separate functional components: RFID tags embedded in wearable devices, RFID readers positioned at attraction locations, and a centralized processing system. This segmentation allows each component to perform its specific function independently, improving reliability while managing complexity through modular architecture.
Solution Approach 2:
RFID technology serves as an intermediary between the guest (wearable device) and the attraction interaction system. The RFID tags and readers automatically detect interactions without requiring direct input from the guest, providing reliable feedback while simplifying the user interface and reducing operational complexity.
2Measurement precision
If multiple RFID tags with different frequencies are used to track various interactions, then the measurement precision of interactions is improved, but the device complexity increases
Solution Approach 1:
The wearable device incorporates multiple RFID tags with different frequencies (e.g., high frequency and ultra high frequency) that can detect different types of interactions at different ranges. This multi-functional approach allows a single wearable device to precisely track various interaction types without requiring multiple separate devices, improving measurement precision while managing complexity.
Solution Approach 2:
The system changes the frequency parameter of RFID tags to optimize detection for different interaction types and distances. By adjusting the frequency parameter, the system achieves precise measurement of various interactions (close-range touches vs. distant approaches) using the same wearable device, avoiding the need for complex multi-device configurations.
3Productivity
If RFID readers transmit electromagnetic radiation to read identification information and write data, then the productivity of interaction tracking is improved, but the use of energy increases
Solution Approach 1:
RFID readers transmit electromagnetic radiation in periodic bursts rather than continuously. This periodic transmission allows the system to maintain high productivity in detecting interactions when needed while significantly reducing energy consumption during idle periods. The wearable devices can respond to these periodic signals and store interaction data locally, minimizing continuous energy usage.
Solution Approach 2:
The RFID tags in wearable devices harvest energy from the electromagnetic radiation transmitted by RFID readers during communication. This energy harvesting capability allows the tags to perform reading and writing operations without requiring additional power from the wearable device's battery, improving productivity of interaction tracking while reducing overall energy consumption from the moving object's perspective.
