Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable monitoring devices for ECG signals face issues with attachment strength deterioration due to incorrect initial attachment and external factors like skin condition or moisture ingress, leading to unreliable long-term monitoring.
Innovation Solution
A wearable monitoring device design featuring a support with electrodes, an attachment part with a first hole, a first cover layer with a second hole, an attachment pad, and a waterproof layer, allowing for easy selection and replacement of the attachment location to maintain robust attachment and prevent moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If integrated electrodes are used for long-term attachment, then monitoring duration is extended, but attachment strength deteriorates due to incorrect initial attachment or external factors
Solution Approach 1:
The device is divided into separable components: a reusable body and replaceable electrode modules. Each electrode module contains an electrode, attachment pad, and cover layer that can be independently replaced. This segmentation allows the monitoring duration to be extended by replacing degraded electrode modules while maintaining the reusable body, thus resolving the contradiction between long-term monitoring and attachment strength deterioration.
2Measurement precision
If attachment location is corrected after initial attachment, then biosignal measurement clarity is improved, but attachment strength deteriorates
Solution Approach 1:
The device incorporates a dynamic replacement mechanism where electrode modules can be easily detached and reattached at different locations. The attachment pad with adhesive layer and cover layer structure allows for simple removal and reattachment without damaging components. This dynamic design enables users to relocate electrodes for optimal biosignal measurement while maintaining attachment strength through proper reattachment procedures.
3Reliability
If attachment surface is replaced when deterioration occurs, then attachment strength is restored, but device complexity increases
Solution Approach 1:
The electrode module is designed as a self-contained segment that can be replaced as a single unit. The module includes the electrode, attachment pad, and cover layer integrated together. This segmentation simplifies the replacement process - users only need to remove the degraded module and attach a new one, rather than replacing multiple separate components. This reduces replacement complexity while restoring attachment strength.
Solution Approach 2:
The electrode is nested within the attachment pad structure, which is itself nested within the cover layer. This nested arrangement allows the entire electrode assembly to be replaced as one integrated unit through a single attachment interface. The nesting design simplifies the replacement mechanism by consolidating multiple functional elements into one replaceable module, thereby reducing device complexity during replacement operations.
