Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the analyte sensor system is miniaturized, then the device size is reduced, but the communication range is reduced
Solution Approach 1:
The patent divides the antenna system into multiple separate antenna elements (first antenna, second antenna, third antenna) with different radiation patterns. This segmentation allows each antenna to be optimized for specific spatial directions, enabling the miniaturized device to maintain communication capability across a broader range of distances and orientations by selectively activating appropriate antenna segments.
2Volume of moving object
If the antenna system is miniaturized, then the device size is reduced, but the RF power efficiency is reduced
Solution Approach 1:
The patent assigns different radiation patterns to different antenna elements, creating local quality variations in the antenna system. The first antenna provides omnidirectional coverage, the second provides directional coverage in a first spatial direction, and the third provides directional coverage in a second spatial direction. This local optimization allows the miniaturized device to concentrate RF power efficiently in specific directions when needed, improving power efficiency despite the reduced overall size.
3Device complexity
If a single antenna is used, then the device complexity is reduced, but the communication reliability is reduced
Solution Approach 1:
The patent implements a dynamic antenna switching system where the controller selectively activates different antenna elements based on spatial conditions, communication requirements, and performance metrics. This dynamic adaptation allows the system to maintain reliable communication by switching to the most appropriate antenna configuration, compensating for the increased complexity through intelligent control that optimizes reliability in real-time.
