Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple parts are used to accommodate sensing circuitry and power source, then the device can process biological information, but the device becomes bulky and creates multiple areas for moisture ingress
Solution Approach 1:
The patent integrates the sensing circuitry, power source, and signal processing components directly into the invasive biosensor assembly itself, merging multiple functional parts into a single integrated unit. This eliminates the need for separate external components connected via wires, thereby reducing the number of parts while maintaining full processing capability.
Solution Approach 2:
The invasive biosensor is designed as a multi-functional device that simultaneously performs sensing, power supply, signal processing, and data transmission functions. The integrated architecture allows a single component to fulfill multiple roles, reducing overall device complexity while preserving adaptability.
2Adaptability or versatility
If multiple parts are connected together to form wearable devices, then the required sensing circuitry can be accommodated, but moisture ingress areas increase due to seals between parts
Solution Approach 1:
By integrating all electronic components (sensing circuitry, power source, processing units) into the invasive biosensor assembly, the patent eliminates multiple connection points and seals between separate parts. This single integrated structure removes the interfaces where moisture could penetrate, thereby improving reliability while maintaining sensing functionality.
3Object-affected harmful factors
If thin wires are used for skin insertion, then the biosensor can be minimally invasive, but electrical connections remain exposed to moisture that affects performance
Solution Approach 1:
The patent integrates the electrical connections and circuitry directly within the invasive biosensor assembly, eliminating exposed wire connections. All electrical pathways are contained within the sealed integrated structure, protecting them from moisture while maintaining minimal invasiveness through the thin wire design.
4Adaptability or versatility
If wearable glucose monitoring devices include multiple parts, then the device can process biological information, but the device size increases making it bulky
Solution Approach 1:
The patent consolidates all functional components (sensing elements, circuitry, power source, and processing units) into a single integrated invasive biosensor assembly. This merger eliminates the need for separate external components, significantly reducing the overall device volume while preserving full biological information processing capability.
