Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple physical layers are utilized to maintain quality of service, then reliability and performance are improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic selection and switching between multiple physical layers (cellular, Bluetooth, WLAN, WiMAX) based on real-time QoS requirements and resource availability. The system continuously monitors communication conditions and adapts the physical layer configuration during operation, allowing the device to maintain high reliability while managing complexity through adaptive rather than static multi-layer management
Solution Approach 2:
The patent creates a universal communication framework that can operate across multiple physical layers with different technologies and ranges. The system design allows a single device to universally support WPAN, WLAN, and cellular networks, enabling it to function effectively in diverse communication scenarios without requiring separate dedicated systems for each network type
2Reliability
If processing and storage capacity are increased to handle multiple physical layers, then quality of service is improved, but device size and weight increase
Solution Approach 1:
The patent merges multiple physical layer functionalities into a unified communication system with shared processing and storage resources. Instead of implementing separate dedicated processing units for each physical layer, the system combines them into a integrated architecture where resources are dynamically allocated based on current QoS requirements, reducing overall device size and weight while maintaining the capability to handle multiple layers
Solution Approach 2:
The system dynamically adjusts processing and storage resource allocation based on the active communication session requirements. When multiple physical layers are simultaneously active, resources are dynamically assigned to meet QoS demands without requiring permanent over-provisioning of hardware capacity, thereby minimizing device size and weight
3Reliability
If transmission power is increased to maintain quality of service across varying wireless technologies, then reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic transmission power control that adjusts power levels based on the specific physical layer being used, signal conditions, and QoS requirements. The system monitors communication quality in real-time and adapts transmission power accordingly, using higher power only when necessary to maintain QoS rather than operating at maximum power continuously, thereby reducing overall power consumption while maintaining reliability
Solution Approach 2:
The system changes transmission power parameters dynamically based on the selected physical layer and current communication conditions. Different power levels are assigned to different physical layers (cellular, Bluetooth, WLAN, WiMAX) according to their specific requirements and signal characteristics, optimizing the balance between reliability and power consumption for each technology
4Use of energy by moving object
If data size is reduced through encoding schemes, then power consumption is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies different data encoding schemes with varying compression ratios and precision requirements based on the selected physical layer and QoS needs. The system dynamically selects encoding parameters that achieve sufficient data reduction for power savings while maintaining error correction capabilities appropriate for each wireless technology's channel conditions, balancing power consumption against manufacturing precision requirements

AI summary
A wireless mobile communication (WMC) device may be determine a quality of service (QOS) required to communicate data. The WMC device may utilize a plurality of physical layers available in the WMC device to retain the QOS throughout the data communication. The physical layers may comprise a plurality of wireless technologies and/or a plurality of transmission power levels within each wireless technology. Selection of physical layers that may be utilized may comprise determination of available QOS through the physical layers, available power in the WMC device, and/or power requirement for communicating data via the physical layers. Data encoding may also be utilized to alter size of communicated data while retaining the required QOS. Data encoding may comprise utilizing encoding schemes, data compression, and/or redundancy bits. A set of deadlines may be utilized to enable switching between available physical layers to ensure maintaining and/or achieving required QOS.
