Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion data integration is implemented to adapt communication parameters, then communication efficiency and signal quality are improved, but device complexity increases
Solution Approach 1:
The patent combines the GPS receiver and RF transceiver into an integrated system where motion data from GPS is merged with communication parameter control. The GPS unit provides motion information that is directly utilized by the RF transceiver to adapt transmit power, antenna configuration, and protocol selection, creating a unified motion-adaptive communication system that improves signal quality while managing complexity through integration.
Solution Approach 2:
The RF transceiver is designed with multi-functionality to handle both standard communication operations and motion-adaptive parameter adjustment. The system can operate in multiple modes: standard communication mode and motion-adaptive mode, allowing the same hardware to serve universal purposes while improving reliability when motion conditions require adaptation.
2Use of energy by moving object
If motion adaptive parameter adjustment is used, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The system dynamically adjusts communication parameters based on real-time motion data from the GPS receiver. When the device is stationary or moving slowly, the system reduces transmit power and uses simpler antenna configurations to conserve energy. When motion increases, the system automatically increases power and complexity of parameters to maintain signal quality, creating a dynamic power management strategy that reduces overall power consumption while managing complexity through conditional activation.
Solution Approach 2:
The patent changes operational parameters (transmit power level, antenna configuration, protocol selection) based on motion state parameters from GPS data. By monitoring motion parameters and adjusting communication parameters accordingly, the system optimizes power consumption - using higher power only when necessary for mobile conditions and lower power when stationary - while the parameter adjustment logic manages complexity through predefined adaptation rules.
3Measurement precision
If GPS receiver and gyrating circuit are integrated, then motion data accuracy is improved, but manufacturing complexity increases
Solution Approach 1:
The patent integrates the GPS receiver and RF transceiver into a single unified device, combining motion sensing capabilities with communication functionality. This merging allows the system to obtain accurate motion data from GPS while eliminating the need for separate motion sensing hardware, thereby improving motion data accuracy for communication adaptation while simplifying the overall manufacturing process compared to integrating multiple independent systems.
Data Source
AI summary
A circuit includes an on-chip gyrating circuit that generates a motion parameter based on motion of the circuit. A global positioning system (GPS) receiver receives a GPS signal and that generates GPS position data based on the GPS signal. A processing module processes the motion parameter to produce motion data, generates position information based on at least one of the GPS position data and the motion data, converts outbound data into an outbound symbol stream, and converts an inbound symbol stream into inbound data. A wireless local area network (WLAN) transceiver section generates an outbound RF signal from the outbound symbol stream, and converts an inbound RF signal into the inbound symbol stream.
