Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor guide wire devices for intravascular measurements require complex and time-consuming battery replacement when the power supply is discharged, leading to potential disruptions in physiological readings.
Innovation Solution
The power supply, such as a battery, is integrated into the disposable sensor guide wire device, eliminating the need for battery replacement and ensuring fresh power when attached to the signal converting device, with an optional power monitoring system to detect battery levels before use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power supply is integrated into the disposable sensor guide wire device, then the need for battery replacement is eliminated and manufacturing is simplified, but the device complexity increases
Solution Approach 1:
The system is divided into a disposable sensor guide wire device containing the power supply and a reusable signal converting device. This segmentation allows the power supply to be integrated into the disposable component, eliminating battery replacement needs while keeping the complex signal converting device separate and reusable.
Solution Approach 2:
The power supply is integrated into the disposable sensor guide wire device rather than the reusable signal converting device. This allows the power supply to be replaced automatically when the disposable guide wire is discarded and a new one is used, eliminating manual battery replacement while keeping the expensive signal converting device reusable.
2Ease of manufacture
If the power supply is integrated into the disposable sensor guide wire device, then manufacturing is simplified and cost is reduced, but the device complexity increases
Solution Approach 1:
By segmenting the system into disposable and reusable components, the power supply integration is confined to the simpler disposable guide wire device. This segmentation simplifies manufacturing of each component while managing overall system complexity through modular design.
Solution Approach 2:
Integrating the power supply into the disposable guide wire device simplifies manufacturing because the power supply becomes a one-time component that is discarded with the guide wire. This eliminates the need for complex battery replacement mechanisms and reduces long-term manufacturing costs despite initial integration complexity.
3Reliability
If a power monitoring system is added to detect battery levels, then the risk of disrupted readings is further minimized, but the device complexity increases
Solution Approach 1:
A power monitoring system is implemented to provide feedback on the power supply status. This feedback mechanism detects battery levels and can alert users or automatically manage power, minimizing the risk of disrupted readings due to discharged batteries while adding only minimal complexity through integrated monitoring circuitry.
Solution Approach 2:
The power monitoring system enables the device to self-monitor its power status, automatically detecting when the battery is discharged or low. This self-service capability minimizes disrupted readings by providing early warning or automatic power management without requiring complex external monitoring systems.
