Solution Overview
Problem
Existing in vivo analyte monitoring systems face challenges in maintaining reliable wireless transmission of analyte data from a sensor control device to a receiving device, particularly due to the need for improved radio frequency communication and antenna configurations to ensure consistent connectivity.
Innovation Solution
The system incorporates a printed circuit board with a Bluetooth low energy antenna supported by risers extending from its surface, a battery for power, and a processor for data processing, along with a connector to establish electrical connections, enhancing the transmission of analyte data through a specific antenna configuration that includes a cross-bar forming an h-shape or y-shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is used to transmit analyte data from the sensor control device to the receiving device, then the usability and convenience of the analyte monitoring system is improved, but the reliability of the transmission signal may be compromised
Solution Approach 1:
The patent applies dimensionality change by transitioning from a planar antenna configuration to a three-dimensional antenna structure using risers. The antenna is positioned above the printed circuit board at a elevated height, creating a spatial separation that improves radio frequency communication reliability while maintaining the wireless transmission convenience.
2Volume of moving object
If the sensor control device is made small in form-factor for comfort and convenience, then the comfort and ease of wear is improved, but the space available for reliable antenna configuration is reduced
Solution Approach 1:
The patent resolves the space constraint by moving the antenna configuration from the two-dimensional plane of the circuit board into the third dimension using risers. This vertical positioning allows the antenna to achieve optimal signal transmission characteristics within the limited volume of a compact sensor control device.
Solution Approach 2:
The patent segments the antenna structure into multiple components: the antenna element itself, the risers that provide vertical support and positioning, and the connection points on the circuit board. This segmentation allows each component to be optimized independently for its specific function while maintaining overall compactness.
