Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If non-invasive analyte detection methods are used, then patient comfort and safety are improved, but detection accuracy and specificity deteriorate due to interference from temperature fluctuations, skin compounds, and pigments
Solution Approach 1:
The patent employs dynamic shape-changing antennas that can reconfigure their geometry in real-time to optimize detection at different frequencies. The controllable conductive material allows the antenna to adapt its shape dynamically, enabling the system to switch between transmission and reception modes and to tune to specific frequency ranges that penetrate biological tissue while minimizing interference from skin compounds and temperature fluctuations.
Solution Approach 2:
The system changes operational parameters by adjusting the shape and configuration of the antenna to operate in different frequency ranges (radio to microwave). This parameter change allows optimization of signal penetration through biological tissue while minimizing interference from skin compounds, sweat, and pigments that affect lower frequency measurements.
2Volume of moving object
If the transmit antenna and receive antenna are positioned close together for compact device design, then device size is reduced, but signal interference increases due to direct communication between antennas
Solution Approach 1:
The patent uses a dynamic shape-changing antenna that can reconfigure its geometry to physically separate the transmit and receive functions. By manipulating the controllable conductive material, the antenna can form distinct transmit and receive shapes that are spatially separated, preventing direct signal coupling while maintaining a compact overall device footprint. The antenna can switch between transmit and receive modes by changing its shape configuration.
Solution Approach 2:
The single shape-changing antenna effectively segments into functionally separate transmit and receive components through its reconfigurable shape. The controllable conductive material allows the antenna to form distinct conductive paths for transmission and reception, creating virtual separation between transmit and receive functions without requiring physically separate antenna structures.
3Device complexity
If fixed-shaped antennas are used for analyte detection, then device complexity is reduced, but detection effectiveness deteriorates due to inability to optimize for different analytes and media
Solution Approach 1:
The patent employs a dynamic shape-changing antenna that can reconfigure its geometry to optimize detection for different analytes and biological media. The controllable conductive material allows real-time adjustment of antenna shape to match optimal detection configurations for various applications, such as detecting glucose in blood versus interstitial fluid, without requiring multiple fixed antennas.
Solution Approach 2:
The single shape-changing antenna provides universal functionality by able to perform multiple detection tasks across different frequency ranges and for different analytes. By manipulating the antenna shape, the same physical structure can be optimized for detecting various substances in different biological media, replacing the need for multiple specialized fixed antennas.
