Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical care facilities, traditional magnetic electrical connection systems pose risks to implanted devices like cardiac pacemakers due to magnetic interference, and existing connectors can cause mechanical damage or injury when subjected to tensile or bending loads.
Innovation Solution
A magnetic connection system using non-permanent magnetic connecting elements, arranged in the plug, which are attracted by magnets in the socket, ensuring safe operation in sensitive areas and automatic disconnection under excessive load, combined with a ball joint or hinge to absorb forces and prevent unintended detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnets are used in both plug and socket for magnetic connection, then secure connection and easy connection process are achieved, but magnetic interference with medical devices occurs
Solution Approach 1:
The patent extracts the permanent magnet from the plug, leaving only in the socket. The plug now contains only non-permanent magnetic connecting elements that are attracted to the magnet in the socket, eliminating the source of harmful magnetic interference while maintaining the magnetic connection function.
Solution Approach 2:
The patent introduces non-permanent magnetic connecting elements as intermediaries in the plug. These elements are attracted to the permanent magnet in the socket but do not themselves generate persistent magnetic fields, thus mediating the connection while reducing harmful magnetic effects.
2Reliability
If traditional magnetic connectors are used, then secure connection is achieved, but mechanical damage or injury can occur under tensile or bending loads
Solution Approach 1:
The patent makes the connection dynamic by using non-permanent magnetic connecting elements that can automatically detach when subjected to excessive tensile or bending loads. This dynamic behavior allows the connection to fail safely rather than causing mechanical damage.
Solution Approach 2:
The magnetic connection strength is designed to provide a safety threshold that cushions against excessive forces. The magnetic attraction force acts as a protective mechanism that fails before critical mechanical damage can occur to the connected devices or components.
