External UWB Component Layout for Low-Footprint Terminal Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of UWB technology into small mobile devices like smartphones poses challenges due to the large footprint of UWB modules and antennas, which can interfere with existing antennas and occupy valuable circuit board space, complicating design and compromising other functionalities.
Innovation Solution
The UWB components are arranged externally to the terminal device, with transmissions like power supply voltage, communication signals, and clock signals being transferred through interface modules, allowing UWB functionalities to be distributed across the device and component, reducing antenna interference and footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UWB modules and antennas are integrated into terminal devices, then UWB functionality is achieved, but the footprint increases and antenna interference risk increases
Solution Approach 1:
The patent divides the UWB system into two separate parts: a UWB module (which can be integrated into the terminal device) and an antenna (which can be separately positioned). This segmentation allows the functional components to be distributed, reducing the footprint requirement while maintaining UWB functionality. The interface module acts as a connection point between the segmented components.
Solution Approach 2:
The patent extends the system from a two-dimensional circuit board layout to a three-dimensional spatial arrangement. By allowing the antenna to be positioned separately (potentially in a different spatial plane or location), the design moves beyond the constraints of the circuit board surface area, effectively reducing the footprint while maintaining functionality.
2Adaptability or versatility
If UWB modules and antennas are integrated into terminal devices, then UWB functionality is achieved, but antenna interference risk increases
Solution Approach 1:
By segmenting the UWB system into separate modules and antennas with an interface module in between, the patent physically separates the components that could cause interference. This spatial separation reduces the electromagnetic interference between the antenna and other antennas or sensitive components within the terminal device.
Solution Approach 2:
The interface module serves as an intermediary between the UWB module and the antenna. This intermediate component can provide isolation, filtering, or impedance matching that reduces interference effects, acting as a buffer that protects the sensitive UWB module from harmful electromagnetic effects while maintaining signal integrity.
3Adaptability or versatility
If more devices are provided for basic functionalities, then functionality increases, but circuit board complexity increases
Solution Approach 1:
The patent segments the UWB system into distinct functional modules that can be independently designed and integrated. The interface module provides a standardized connection point that simplifies the integration process, reducing the overall circuit board complexity despite adding new functionality. This modular approach allows each component to be optimized independently.
