Electromedical Electrode Connector With Openable Insulating Contact Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electromedical electrodes face challenges in preventing accidental coupling of signals when connected to pulse generators or evaluation units, particularly when implanted in patient tissue, due to exposed contact poles.
Innovation Solution
A connection plug with a non-conductive protective layer that can be locally opened to allow electrical contact, ensuring protection against unwanted interference and simplifying handling by automatically establishing conductive connections when mating with a corresponding plug.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the contact pole is left exposed for easy connection, then the ease of operation is improved, but the risk of accidental signal coupling increases
Solution Approach 1:
A non-conductive protective layer is applied to the contact pole before use, preventing accidental signal coupling. The protective layer is then automatically removed or opened during the connection process, ensuring both safety and ease of connection without requiring separate manual intervention.
Solution Approach 2:
The non-conductive protective layer acts as an intermediary between the contact pole and the external environment. It provides protection during handling and storage, and is designed to be automatically removed or opened during the connection process, facilitating both safety and ease of operation.
2Object-affected harmful factors
If the contact pole is covered with a protective layer for safety, then protection against accidental contact is improved, but the ease of operation deteriorates due to additional removal steps
Solution Approach 1:
The protective layer removal function is merged with the connection process itself. The mating connector incorporates means to automatically remove or open the protective layer during insertion, combining two operations (protection removal and connection establishment) into a single action, thereby maintaining safety without adding handling complexity.
Solution Approach 2:
The connection system is designed to automatically remove or open the protective layer without requiring separate manual intervention. The mating connector performs the protective layer removal as part of its own connection mechanism, making the system self-servicing and eliminating additional user steps.
3Ease of operation
If the protective layer is removed before connection, then the ease of operation is improved, but the risk of interference signals coupling in increases
Solution Approach 1:
The protective layer is applied in advance to the contact pole during manufacturing, providing immediate protection against interference signals and accidental contact. The protective layer is designed to be automatically removed or opened during the connection process, ensuring protection is maintained until the moment of connection.
Solution Approach 2:
The non-conductive protective layer serves as an intermediary that blocks interference signals during handling and storage. It is designed to be automatically removed or opened during connection, allowing electrical contact to be established only when intended, thus preventing interference signal coupling while maintaining handling simplicity.
