Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
USB devices with integrated antennas face interference issues due to their small size and internal circuitry, which affects the propagation and reception of radio frequency signals during wireless communication.
Innovation Solution
An attached protective cover with a cap and link that positions the antenna away from the USB device's body, creating an air interface and reducing interference, while maintaining an electrical connection between the antenna and the wireless connection system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna is fabricated on an interior board surface located in the USB device, then the USB device can provide wireless connectivity, but the circuitry within the USB device causes interference with the antenna and impacts the propagation and reception of radio frequency signals
Solution Approach 1:
The antenna is extracted from the USB device body and placed on an externally attached protective cover. This separation removes the antenna from the interfering circuitry environment while maintaining wireless connectivity functionality. The protective cover with integrated antenna becomes a distinct component that can be attached to or removed from the USB device.
Solution Approach 2:
A protective cover serving as an intermediary component is introduced between the USB device and the antenna. This cover includes a link that provides both physical connection and electrical connection (signal path) to the antenna, while physically separating it from the interfering circuitry. The link acts as a mediator that maintains electrical connectivity while enabling spatial separation.
2Reliability
If the antenna is positioned away from the USB device body to reduce interference, then wireless signal transmission and reception is improved, but the device structure becomes more complex with additional components
Solution Approach 1:
The protective cover is designed to serve multiple functions simultaneously: it protects the USB plug from physical damage, provides structural support for the antenna, maintains electrical connection to the USB device through the link, and enables wireless communication by housing the antenna. This multi-functionality reduces the need for separate components and justifies the added structure.
Solution Approach 2:
The protective cover merges several functions into a single component: physical protection of the USB connector, structural support for the antenna, and electrical connection pathway. The link combines both mechanical attachment and electrical signal transmission functions. This merging reduces overall system complexity compared to having separate components for each function.
