Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-channel receiver systems require multiple single-channel receiver ICs, increasing costs and power consumption, and wideband receivers are inefficient for single-channel services that require low power, such as Voice over IP (VoIP).
Innovation Solution
A receiver unit capable of operating in both single-channel and multi-channel modes, switching between modes to optimize power consumption and signal processing complexity, using frequency converting entities and filter entities to downconvert RF signals to intermediate frequencies for output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple single-channel receiver ICs are used to receive multiple channels, then channel reception capability is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent combines multiple single-channel receiver ICs into a single integrated multi-channel receiver IC that can process multiple channels simultaneously. This merging approach maintains the channel reception capability while reducing device complexity by consolidating multiple separate components into one unified device.
Solution Approach 2:
The receiver unit is designed with multi-functionality to operate in both single-channel mode and multi-channel mode. This universal design allows the same hardware to adapt to different service requirements, providing channel bonding capability when needed while maintaining compatibility with existing single-channel services.
2Adaptability or versatility
If multiple single-channel receiver ICs are used to receive multiple channels, then channel reception capability is improved, but power consumption increases
Solution Approach 1:
By merging multiple receiver ICs into one integrated multi-channel receiver IC, the patent reduces the total power consumption while maintaining multi-channel reception capability. The integrated design allows for more efficient power management and reduces the cumulative power draw of multiple separate devices.
Solution Approach 2:
The receiver unit dynamically switches between single-channel mode and multi-channel mode based on service requirements. This dynamic operation allows the system to consume only the necessary amount of power for the current task, avoiding the continuous high power consumption that would result from always operating in multi-channel mode with multiple ICs.
3Device complexity
If a wideband receiver IC is used to receive multiple channels, then device complexity is reduced, but power consumption increases and adaptability to single-channel services decreases
Solution Approach 1:
The receiver unit employs dynamic mode switching between single-channel and multi-channel operations. This dynamic capability allows the simplified wideband receiver architecture to adapt to single-channel services when required, maintaining versatility while benefiting from the reduced device complexity of the integrated design.
Solution Approach 2:
The wideband receiver IC is designed with universal functionality to handle both single-channel and multi-channel services. This multi-functionality ensures that the simplified hardware design does not sacrifice adaptability, allowing the same device to serve diverse service requirements efficiently.
4Device complexity
If a wideband receiver IC is used to receive multiple channels, then device complexity is reduced, but power consumption increases
Solution Approach 1:
The receiver unit dynamically adjusts its operation mode based on service requirements, switching between single-channel and multi-channel modes. This dynamic operation allows the wideband receiver to consume lower power when operating in single-channel mode, thereby reducing overall power consumption while maintaining the benefits of reduced device complexity.
