Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices with magnetic connections face challenges in maintaining optimal magnetic field strength, as it can vary among individuals and over time, potentially causing discomfort or damage to intervening tissue, and existing solutions lack flexibility in adjusting magnetic strength without swapping magnet sets.
Innovation Solution
The technology allows for the modification of magnetic strength between a wearable medical device and an implantable device by altering the orientation of a magnet set, using an asymmetric magnet case that changes the magnetic connection's strength when flipped, enabling users to adjust the magnetic securing force without replacing magnet sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed-strength magnet set is used to secure the wearable device to the implantable device, then reliable device retention is achieved, but tissue discomfort or damage may occur due to excessive magnetic field strength
Solution Approach 1:
The magnet case is designed to rotate about an axis, allowing the magnet set to dynamically change orientation between a first orientation (providing stronger magnetic securing force for reliable retention) and a second orientation (providing weaker magnetic securing force to reduce tissue discomfort). This dynamic adjustment enables the system to adapt magnetic field strength based on user needs while maintaining reliable device retention when required.
Solution Approach 2:
The invention changes the magnetic field strength parameter by altering the orientation of the magnet set within the magnet case. By rotating the magnet case between different orientations, the effective magnetic field strength applied to the tissue and the securing force between devices can be adjusted without changing the magnet set itself, thus resolving the contradiction between reliable retention and tissue safety.
2Force
If the magnetic field strength is increased to ensure secure device connection, then device retention is improved, but the risk of tissue damage increases
Solution Approach 1:
The magnet case enables dynamic adjustment of magnetic securing force by rotating between orientations. In the first orientation, the magnet set provides maximum magnetic securing force for secure device connection. In the second orientation, the magnetic securing force is reduced to minimize tissue damage risk, thus allowing the system to adapt force levels based on operational requirements.
Solution Approach 2:
The magnet case is designed with asymmetric magnetic properties or geometry that creates different magnetic field strengths in different orientations. This asymmetry allows the same magnet set to provide both strong securing force (when oriented for maximum attraction) and reduced force (when oriented for minimum tissue impact), resolving the contradiction between connection security and tissue safety.
3Adaptability or versatility
If different magnet sets are swapped to adjust magnetic strength, then magnetic field strength customization is achieved, but device complexity and user operation difficulty increase
Solution Approach 1:
Instead of requiring users to physically swap different magnet sets to adjust magnetic strength, the invention implements a dynamic solution where a single magnet set can be rotated within its case to change orientation. This allows users to adjust magnetic field strength by simply rotating the magnet case between predefined orientations, greatly simplifying operation while maintaining adaptability for different user needs and activity levels.
Solution Approach 2:
The magnet case structure serves multiple functions: it houses the magnet set, provides a rotation mechanism for orientation adjustment, and enables magnetic strength customization without requiring multiple separate magnet sets. This multi-functionality achieves adaptability while keeping the device design compact and user operation simple.

AI summary
A magnetic connection can be formed between a magnet set of a first device and magnet set of a second device. The magnetic strength of the magnetic connection can be modified by changing an orientation of a magnet set of a first device from a first orientation to a second orientation. The magnet set or a case in which the magnet set is disposed can be asymmetric, such that alternating between the first and second orientations results in different magnetic connections.
