Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting ruptures in prosthetic implants, such as palpation and ultrasound, are inaccurate and costly, with a need for a more sensitive and cost-effective alternative to Magnetic Resonance Imaging (MRI), especially for early detection and pre-implantation integrity assessment.
Innovation Solution
An implant with a conductive layer between the shell and core, equipped with a sensor to detect changes in electrical properties, allowing for single-point rupture detection independent of bodily fluid ingress, and a kit with a receiving device for wireless communication to assess shell integrity before and after implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If MRI is used to detect rupture, then measurement precision is improved, but cost and time consumption increase
Solution Approach 1:
The patent replaces the mechanical/imaging-based MRI system with an electrical sensing system. A conductive layer is embedded within the implant shell, and a sensor detects changes in electrical properties (such as capacitance or resistance) of this conductive layer. When rupture occurs, the electrical properties change, providing immediate detection without requiring time-consuming MRI scans.
Solution Approach 2:
The conductive layer acts as an intermediary between the shell structure and the sensor. Instead of directly imaging the rupture, the sensor detects electrical property changes in the conductive layer that occur when the shell is compromised, providing an indirect but rapid detection method.
2Measurement precision
If MRI is used to detect rupture, then measurement precision is improved, but cost increases
Solution Approach 1:
The patent employs a cost-effective electrical sensing system with a conductive layer and simple sensor, replacing the expensive MRI system. The sensor and conductive layer are integrated into the implant during manufacturing, providing affordable continuous monitoring without requiring expensive medical imaging equipment.
Solution Approach 2:
The patent replaces the expensive MRI imaging system with a low-cost electrical detection system that uses basic electrical measurements (capacitance, resistance) to detect rupture, significantly reducing the cost barrier for monitoring.
3Ease of operation
If palpation is used to detect rupture, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The implant performs self-diagnosis through the integrated sensor that continuously monitors electrical properties of the conductive layer. The system automatically detects rupture without requiring manual manipulation or skilled intervention, providing both ease of operation and high precision simultaneously.
Solution Approach 2:
The patent replaces manual palpation with an automated electrical sensing system that objectively measures electrical property changes, eliminating the subjectivity and inaccuracy of manual detection while maintaining ease of use.
4Ease of manufacture
If sensor is positioned on outer surface of implant shell, then ease of manufacture is improved, but reliability deteriorates due to damage during implantation
Solution Approach 1:
The sensor is nested within the implant structure, specifically positioned inside the shell rather than on the outer surface. This protects the sensor from damage during implantation and handling, while the conductive layer extends to the inner surface to maintain electrical monitoring capability.
Solution Approach 2:
The conductive layer serves as an intermediary that extends the sensing capability to the inner surface of the shell, allowing the sensor positioned inside to detect rupture at the critical inner interface without requiring the sensor itself to be exposed to external damage risks.
5Device complexity
If detection relies on bodily fluid ingress, then device complexity is reduced, but measurement precision deteriorates and detection timing is delayed
Solution Approach 1:
The patent replaces fluid-based detection mechanisms with direct electrical property measurement. The sensor continuously monitors electrical characteristics of the conductive layer, providing immediate and precise detection independent of fluid ingress, eliminating the delay and imprecision associated with fluid-based methods.
