Implant Accessory Positioning Along Body Curvature Without Magnets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic implants, such as neural and cardiac implants, face challenges in maintaining optimal interaction with accessory devices due to incorrect positioning and orientation, leading to poor communication and extended charging times, and the use of magnets can interfere with MRI diagnostics.
Innovation Solution
A positioning device that includes a base, engagement interfaces, drive units, and a controller to move the accessory device in a curved motion along the body contour, optimizing interaction parameters for improved positioning without relying on magnets, thus enhancing communication and charging quality while avoiding MRI artifacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnets are used to position the accessory device, then positioning is simplified, but MRI diagnostics are interfered with
Solution Approach 1:
The patent removes magnets from the system entirely, extracting the harmful magnetic field source while maintaining positioning functionality through alternative means (mechanical or electromagnetic coupling without permanent magnets), thereby eliminating MRI interference while preserving ease of operation
Solution Approach 2:
The patent replaces magnetic positioning mechanisms with alternative positioning methods that do not rely on magnetic fields, such as mechanical coupling or controlled electromagnetic actuation, substituting the magnetic field-based system with a non-magnetic approach to avoid MRI conflicts
2Adaptability or versatility
If the accessory device is held manually in position, then positioning is flexible, but interaction quality deteriorates over time due to user fatigue and involuntary movement
Solution Approach 1:
The patent implements a dynamic positioning system where the accessory device can be actively adjusted and repositioned automatically, allowing the system to adapt to movement or changes in position while maintaining optimal interaction quality through real-time control rather than static manual holding
Solution Approach 2:
The positioning system operates autonomously without requiring continuous user intervention, with the device self-adjusting or self-maintaining its position through automated mechanisms, eliminating user fatigue and involuntary movement issues while preserving positioning flexibility
3Device complexity
If the accessory device is positioned incorrectly, then device complexity is reduced, but communication quality and charging efficiency deteriorate
Solution Approach 1:
The patent implements preliminary positioning actions that automatically align the accessory device with the implant before interaction begins, ensuring optimal positioning is achieved in advance through automated guidance or alignment mechanisms, thereby guaranteeing high communication and charging efficiency without requiring complex real-time adjustment mechanisms
