Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If low-cost and low-power wireless devices are used, then device complexity and power consumption are reduced, but the ability to establish radio resource control connections and access cellular networks deteriorates
Solution Approach 1:
The patent introduces a relay wireless device as an intermediary between the remote wireless device and the cellular base station. The relay device receives paging information from the base station via a cellular connection and forwards it to the remote device through a relay link, enabling network access for devices with limited direct communication capabilities.
2Reliability
If relay wireless devices forward paging information to remote wireless devices, then network access capability of remote devices is improved, but device complexity of the relay system increases
Solution Approach 1:
The relay wireless device performs multiple functions: it maintains a cellular connection with the base station, receives paging information intended for remote devices, and forwards this information through a relay link. This multi-functionality consolidates the relay capability in a single device type that can serve multiple remote devices.
3Area of stationary object
If paging information is forwarded via relay link, then coverage range is extended to remote devices, but information transmission reliability may deteriorate due to additional relay hop
Solution Approach 1:
The relay wireless device acts as a trusted intermediary that receives paging information from the base station and forwards it to the remote device. This approach extends coverage to devices that cannot directly communicate with the base station while maintaining reliability through the relay's established cellular connection.
