Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antenna elements are used to reduce multipath interference, then signal quality is improved, but processor loading and power consumption increase
Solution Approach 1:
The patent implements dynamic adjustment of multipath search window sizes based on real-time power status and signal quality conditions. The processing system adapts the search window parameters for each antenna element, making the processing load dynamic rather than fixed, thereby reducing power consumption when full processing capability is not needed while maintaining signal quality when required
Solution Approach 2:
The patent changes the processing parameters (multipath search window sizes) based on power status and signal quality measurements. By adjusting these parameters dynamically, the system optimizes the balance between processing effort and performance, reducing power consumption during normal operation while maintaining reliability when signal conditions deteriorate
2Reliability
If multiple antenna elements are used to reduce multipath interference, then signal quality is improved, but processor loading increases
Solution Approach 1:
The processing system dynamically adjusts the multipath search window sizes based on power status and signal quality, making processor loading adaptive rather than constant. This allows the system to reduce processing demands when full capability is not required while maintaining high processing levels when signal quality depends on it
Solution Approach 2:
The patent applies partial processing action by adjusting search window sizes to match actual needs. Instead of always processing all antenna elements at full capacity, the system applies only the necessary processing level required to maintain acceptable signal quality, reducing overall processor loading
3Reliability
If multipath search windows are processed for all antenna elements, then multipath interference is mitigated, but battery life decreases
Solution Approach 1:
The system dynamically adjusts multipath search window processing based on power status and signal quality conditions. When power is abundant and signal quality is good, full processing is applied. When power is limited or conditions are acceptable, processing is reduced, thereby extending battery life while maintaining interference mitigation capability when needed
Solution Approach 2:
The patent changes processing parameters (search window sizes and processing intensity) based on battery power status. This allows the system to extend battery life by reducing processing when full capability is not required, while maintaining multipath interference mitigation through adaptive parameter adjustment rather than fixed full-capacity operation
