Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices lack an effective mechanism to indicate when electrode patches have reached the end of their predetermined lifespan or have deteriorated, leading to potential loss of functionality and patient safety concerns.
Innovation Solution
Incorporating an indicating mechanism within electrode patches and external medical devices to monitor and signal when the patches have reached their predetermined lifespan or have compromised integrity, using methods such as impedance measurement and visual, audible, or tactile alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electrode patches are used for extended periods to reduce replacement frequency, then productivity is improved, but reliability deteriorates due to potential deterioration and loss of functionality
Solution Approach 1:
The electrode patch includes an indicating mechanism that is activated in advance when the patch reaches its predetermined lifespan or shows signs of deterioration. This preliminary indication allows clinicians to replace the electrode before complete failure occurs, maintaining both extended use benefits and reliability.
Solution Approach 2:
The indicating mechanism provides continuous feedback about the electrode's operational status and remaining lifespan. This feedback system enables proactive replacement scheduling, allowing the electrode to be used for its full safe lifespan while preventing unexpected failure.
2Device complexity
If no indication mechanism is provided, then device complexity is reduced, but loss of information occurs regarding electrode lifespan and integrity status
Solution Approach 1:
The electrode patch is self-monitoring through its integrated indicating mechanism that automatically tracks its own lifespan and integrity status. This eliminates the need for external tracking systems while providing comprehensive information about the electrode's operational state.
Solution Approach 2:
The indicating mechanism utilizes color changes to communicate electrode status and remaining lifespan visually. This provides clear, intuitive information about electrode integrity without requiring complex displays or additional equipment, maintaining simplicity while preventing information loss.
3Reliability
If indicative features are added to electrode patches, then reliability is improved through timely replacement, but manufacturing precision requirements increase
Solution Approach 1:
The indicating mechanism is integrated directly into the electrode patch structure itself, combining the monitoring function with the existing electrode components. This merger reduces the need for separate precision-aligned components and simplifies the manufacturing process while maintaining reliable indication.
Solution Approach 2:
The indicating mechanism is designed as a disposable component that is replaced with the electrode patch itself. This eliminates the need for durable, high-precision indicating mechanisms that would require complex manufacturing, while still providing reliable lifespan indication throughout the electrode's intended use period.
