Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device uses fixed MIMO configuration, then device complexity is reduced, but communication reliability deteriorates due to hardware characteristic changes when folded or unfolded
Solution Approach 1:
The patent implements dynamic MIMO configuration where the base station and electronic device adjust MIMO parameters (number of layers, antenna ports) based on real-time detection of device state (folded/unfolded). This dynamic adaptation ensures communication reliability maintains performance consistency across different device configurations without requiring multiple fixed configuration sets.
Solution Approach 2:
The patent changes MIMO communication parameters according to device state. When the device transitions between folded and unfolded states, the system modifies parameters such as the number of MIMO layers and antenna port configurations to match the current hardware arrangement, thereby maintaining optimal communication performance without increasing operational complexity.
2Reliability
If the device adapts MIMO configuration to device state, then communication performance consistency is improved, but device complexity increases due to state detection and parameter adjustment mechanisms
Solution Approach 1:
The patent employs a feedback mechanism where the electronic device detects its own state (folded or unfolded) and communicates this information to the base station. The base station then adjusts MIMO configuration based on this feedback. This closed-loop approach ensures performance consistency while distributing complexity between device and network, avoiding excessive device-side complexity.
Solution Approach 2:
The patent introduces state information as an intermediary element that bridges the device's physical state and the MIMO configuration. Rather than directly complex device hardware for adaptation, the system uses state detection and parameter signaling as intermediaries to coordinate between device state and communication configuration, simplifying the overall system architecture.
3Adaptability or versatility
If the device transmits state information to base station, then adaptability is improved, but loss of time increases due to additional signaling overhead
Solution Approach 1:
The patent performs state detection and configuration preparation in advance. The electronic device detects its state and prepares appropriate MIMO parameter information before communication begins or before state transitions occur. This preliminary action reduces the need for real-time signaling adjustments, minimizing time loss while maintaining adaptability.
Solution Approach 2:
The patent uses multi-functional signaling where the same communication channels and protocols are utilized for both regular data transmission and state information reporting. By making the signaling mechanism universal rather than dedicated, the system avoids additional time overhead while maintaining adaptability to different device states.
