Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless subsystems operate concurrently in the same frequency channel band, then wireless communication functionality is improved, but radio frequency interference between subsystems increases
Solution Approach 1:
The patent implements dynamic configuration of wireless circuitry by adjusting transmit power levels, signal chain settings, and operational modes based on real-time interference conditions. The system dynamically switches between different transmission modes (e.g., MIMO modes) and adjusts power levels to mitigate interference between co-located wireless subsystems while maintaining concurrent operation.
Solution Approach 2:
The patent changes operational parameters such as transmit power levels, frequency channel selections, and signal processing configurations to resolve interference. By modifying these parameters dynamically, the system allows multiple wireless subsystems to operate concurrently without severe interference, balancing communication functionality with interference mitigation.
2Speed
If transmit power level is increased to improve transmission range, then transmission distance is improved, but radio frequency interference to other subsystems increases
Solution Approach 1:
The system dynamically adjusts transmit power levels based on the operational state of other wireless subsystems. When interference conditions are detected, the system reduces power levels or switches to alternative transmission modes, thereby maintaining transmission range while minimizing harmful interference to other subsystems.
Solution Approach 2:
The patent implements periodic monitoring and adjustment of transmission parameters. The system periodically evaluates interference conditions and adjusts power levels accordingly, creating a cyclic process of transmission and adjustment that balances range requirements with interference mitigation.
3Productivity
If high-speed wired connection ports operate at full speed, then data throughput is improved, but radio frequency interference to wireless subsystems increases
Solution Approach 1:
The system dynamically configures wired connection ports based on the operational state of wireless subsystems. When wireless subsystems are active and vulnerable to interference, the system adjusts wired port operations to reduce RF emissions, thereby maintaining high data throughput while protecting wireless communications from interference.
4Object-generated harmful factors
If frequency channel bands are selected to avoid interference, then radio frequency interference is reduced, but available communication options decrease
Solution Approach 1:
The system dynamically selects frequency channel bands based on real-time interference conditions and the operational states of all wireless subsystems. Rather than being fixed, the available frequency options are dynamically adjusted to optimize communication while avoiding severe interference, thereby maintaining versatility when conditions permit and reducing interference when necessary.
