Engineering Contradiction Analysis
1Duration of action of moving object
If wireless user devices use low RF transmitting power to extend battery durability, then battery life is improved, but signal transmission reliability deteriorates
Solution Approach 1:
The system segments the receiving function by introducing an auxiliary receiving circuit with auxiliary antenna in addition to the primary receiving circuit. This segmentation allows the primary circuit to handle strong signals while the auxiliary circuit captures weak reflected signals, enabling the user device to transmit at lower power while maintaining connection reliability through signal combining at the access point.
Solution Approach 2:
The auxiliary receiving circuit acts as an intermediary that captures weak reflected signals from the environment (multi-path components) and feeds them to the signal combining circuit. This intermediary function allows low-power transmissions to be compensated by recovering otherwise lost signal energy from reflections and barriers.
2Reliability
If MIMO system and multiple antennas are used to improve signal reception, then receiving performance is improved, but device complexity and cost increase
Solution Approach 1:
The invention extracts only the essential auxiliary receiving function needed to capture weak reflected signals, rather than implementing a full MIMO system with multiple transmit and receive antennas. The auxiliary receiving circuit is a simplified extraction of the receiving capability that targets specifically at recovering weak multi-path signals without the complexity of complete MIMO implementation.
Solution Approach 2:
Instead of implementing full MIMO with multiple transmit antennas, the system applies partial action by adding only one auxiliary receiving circuit and antenna. This partial approach provides sufficient signal recovery capability for low-power transmissions without the excessive complexity and cost of complete MIMO systems.
3Reliability
If high gain directional antenna is used to improve receiving performance, then signal reception is improved, but adaptability to different environments deteriorates
Solution Approach 1:
The auxiliary receiving circuit is designed with universal functionality to capture signals from multiple directions and environments. Unlike high gain directional antennas that are optimized for specific directions, the auxiliary circuit can receive reflected signals from various paths and barriers, making it adaptable to different indoor environments with walls, furniture, and other obstacles.
Solution Approach 2:
The system dynamically combines signals from both the primary and auxiliary receiving circuits based on signal strength and quality. The signal combining circuit adaptively processes the auxiliary signal to compensate for weak transmissions, providing dynamic performance adjustment that adapts to different environmental conditions rather than being fixed to a specific directional pattern.
