Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If traditional wireless networks (WLAN, Bluetooth) are used for communication, then data transmission can be achieved, but the range is limited and power consumption increases
Solution Approach 1:
The patent changes the operating frequency parameter from traditional 2.4 GHz or 5 GHz WLAN bands to lower frequency bands (e.g., 900 MHz, sub-1 GHz). This parameter change enables longer communication range due to better propagation characteristics while reducing power consumption requirements for maintaining the same signal strength over distance
Solution Approach 2:
The patent introduces a dual-mode communication architecture that operates in both traditional WLAN mode and extended-range mode simultaneously or alternatively. This dimensional approach allows the system to switch between communication paradigms based on range and power requirements, achieving extended range without proportionally increasing power consumption
2Reliability
If cellular infrastructure is used for communication, then long-distance communication is achieved, but the system becomes dependent on central infrastructure which may be unavailable in remote or emergency situations
Solution Approach 1:
The patent segments the communication network into decentralized peer-to-peer connections rather than relying on a centralized cellular infrastructure. Each device acts as both endpoint and potential relay node, creating multiple independent communication paths that maintain reliability when central infrastructure is unavailable
Solution Approach 2:
The patent introduces intermediate relay nodes that facilitate communication between devices without requiring central infrastructure. These intermediary devices forward data packets across the network, enabling long-distance communication through multiple hops while maintaining decentralized operation and infrastructure independence
3Length of stationary object
If multihop ad hoc networks are used to extend range, then communication range increases, but the number of hops increases administrative overhead and reduces reliability
Solution Approach 1:
The patent implements feedback mechanisms where relay nodes report signal strength, packet loss rates, and route quality to source and destination devices. This feedback enables dynamic route selection and adjustment, preferring paths with fewer hops or better quality, thereby maintaining reliability while achieving extended range through multihop communication
Solution Approach 2:
The patent employs dynamic routing protocols that continuously adapt to changing network conditions. Routes are not static but are dynamically selected and adjusted based on real-time metrics such as node availability, signal quality, and hop count, allowing the system to optimize for both range extension and transmission reliability
Data Source
AI summary
A wireless communication device, comprising radio frequency transceivers which transmit outbound messages to targeted receivers, and receive the inbound messages addressed to the respective transceiver; each having a processor which controls the transceiver to establish communication sessions according to a protocol, and processes targeting and address information. The transceiver communicates with a telephone device having a telephone address book containing information which defines the targets and address for a telephone network and perhaps other networks. The address book entries are human editable through a human machine user interface. The address book entries are intended for centrally controlled switch networks having hierarchically formatted address information, but since these are at least quasi-unique, they are used as address labels in an unswitched peer-to-peer network formed of the transceivers. This permits a common address scheme across the peer-to-peer network and switched network of the telephone device.
