Integrated Sensor Holder Layout for Moisture-Sealed Biosensor Wires
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.
Innovation Solution
A sensor holder device with a rigid body, legs, and a sensor guiding structure that supports and aligns sensor wires, providing structural support and electrical connections while minimizing moisture ingress and reducing device bulkiness.
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 sensor holder into a single unified device structure. The sensor holder device serves multiple functions: it mechanically supports the sensor wire, provides electrical connections through integrated traces, and houses the electronic components within a compact enclosure, eliminating the need for separate coupled parts.
2Adaptability or versatility
If multiple parts are used to accommodate sensing circuitry and power source, then the device can process biological information, but multiple areas for moisture ingress are created
Solution Approach 1:
By consolidating all electronic components and the sensor holder into a single integrated device with a unified enclosure, the patent eliminates multiple internal seals and interfaces that would otherwise create moisture ingress pathways. The integrated design ensures fewer junctions where moisture could penetrate.
3Volume of moving object
If the device size is reduced to improve wearability, then comfort is improved, but accommodating sensing circuitry and power source becomes difficult
Solution Approach 1:
The patent utilizes three-dimensional space efficiently within the device enclosure, arranging components in vertical and layered configurations rather than only horizontal layouts. The sensor holder extends vertically from the circuit board, and components are stacked or positioned to maximize space utilization, enabling compact form factor while accommodating all necessary components.

AI summary
In some examples, a sensor holder device is described. The sensor holder device may include a rigid body, a set legs attached to the rigid body, a sensor guiding structure, a sensor retaining structure, and an electrical trace. The sensor retaining structure may be sized to accommodate a sensor wire. The electrical trace may extend proximate the sensor retaining structure and along one of the legs.
