Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic connection is implemented using signal strength detection, then ease of operation is improved, but reliability deteriorates due to signal instability
Solution Approach 1:
The system performs preliminary signal strength measurements and stabilization calculations before initiating the connection. The mobile computing device continuously monitors the radio signal from the self-propelled device and pre-processes the RSSI values using linear regression to predict the stabilized signal strength, ensuring connection reliability before the actual connection event occurs.
Solution Approach 2:
The system implements continuous feedback by monitoring the radio signal strength and using linear regression to predict stabilized RSSI values. The connection decision is based on feedback from the signal strength trends over time rather than instantaneous values, and the system can adjust connection parameters based on the predicted signal quality to maintain reliable operation.
2Measurement precision
If signal strength stabilization is performed, then measurement precision is improved, but loss of time increases due to processing requirements
Solution Approach 1:
The system performs signal strength measurements and linear regression calculations at periodic intervals rather than continuously. By sampling the RSSI values at regular time periods and using linear regression to predict the stabilized signal strength from these periodic measurements, the system achieves accurate signal strength determination while minimizing processing time and computational overhead.
3Reliability
If continuous signal monitoring is implemented, then reliability is improved, but use of energy increases
Solution Approach 1:
The mobile computing device monitors the radio signal from the self-propelled device at periodic intervals rather than continuously. The system uses linear regression on these periodic measurements to predict stabilized signal strength, maintaining connection reliability while significantly reducing the energy consumption associated with continuous signal monitoring and processing.

AI summary
Systems and methods for facilitating automatic connection between a mobile computing device and a self-propelled device are provided. The self-propelled device can transmit a radio signal in a sleep mode. The mobile computing device may detect the radio signal and generate a visual representation of the signal strength to facilitate in establishing an automatic connection. Once the signal strength crosses a predetermined threshold, a connection and control sequence may be initiated automatically in which a control mode may be initiated on the mobile computing device to enable user control of the self-propelled device.
