Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Invasive biosensors, such as wearable glucose monitoring devices, face performance issues due to moisture exposure and bulkiness, which affect calibration and increase noise levels, and are exacerbated by multiple parts that create moisture ingress points and bulkiness.
Innovation Solution
A sensor holder device with a rigid body, legs, sensor guiding structure, and electrical traces that structurally support and electrically connect sensor wires, reducing moisture ingress and device bulkiness by using a unique shape that efficiently utilizes space and aligns wires for optimal performance.
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 combines the sensor wire, electrical connections, and support structure into a single integrated sensor holder device. The rigid body with integrated legs and electrical traces eliminates the need for separate housing and mounting components, reducing the number of parts while maintaining full functionality for glucose sensing and signal processing.
Solution Approach 2:
The sensor holder device performs multiple functions simultaneously: it provides structural support for the sensor wire, establishes electrical connections through integrated traces, guides the sensor wire during insertion, and protects against moisture. This multi-functionality eliminates the need for separate specialized components.
2Adaptability or versatility
If multiple parts with seals are used to house sensing circuitry, then the device can process biological information, but moisture can still ingress through seal areas
Solution Approach 1:
By integrating the electrical connections directly into the sensor holder device structure, the patent eliminates multiple separate sealed compartments and interfaces. The single-piece construction with built-in electrical traces removes the seal interfaces that would otherwise be vulnerable to moisture ingress.
3Ease of operation
If a compact design is implemented, then wearer comfort is improved, but space for electrical connections and circuitry is reduced
Solution Approach 1:
The electrical connections are arranged in a planar configuration on the rigid body surface, utilizing two-dimensional space efficiently. The electrical traces are distributed across the surface area rather than requiring three-dimensional volume, enabling compact design while maintaining adequate connection space.
