Screw-Type Electrode With Groove for Plug Wire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current EEG and brain stimulation methods face challenges in accurately measuring and delivering signals due to invasive procedures and signal noise from loosely connected electrodes and wires.
Innovation Solution
A screw-type electrode with a screw thread and a groove for a plug-type wire, allowing for minimal invasive insertion using a screw driver, and gradations for precise depth control, ensuring tight connection to minimize signal noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drill is used for inserting the electrode into the skull, then the insertion can be achieved, but the surgical procedure becomes complex and patient discomfort increases
Solution Approach 1:
The patent replaces the drill-based mechanical insertion system with a screw-type electrode that can be inserted using a simple screw driver. The electrode incorporates a screw thread that engages with the skull bone, allowing for controlled insertion without the need for complex drilling equipment or procedures.
2Reliability
If the wire is loosely connected to the electrode, then the connection is easy to make, but signal noise increases
Solution Approach 1:
The patent employs a nested connection structure where the wire is inserted into a groove formed on the electrode body. This groove provides a secure receptacle for the wire, ensuring tight mechanical and electrical connection while maintaining ease of assembly through a simple insert-and-secure operation.
3Ease of operation
If a screw thread is formed on the electrode, then insertion into the skull is facilitated, but the electrode structure becomes more complex
Solution Approach 1:
The patent divides the electrode into functionally distinct segments: a screw thread portion for engagement with the skull, a body portion housing the groove for wire connection, and an electrode tip for signal acquisition. This segmentation allows each component to perform its specific function efficiently while maintaining overall structural coherence.

AI summary
A screw-type electrode capable of being coupled to a plug-type wire may include a first part having a screw thread to easily insert the electrode into the skull of a patient; and a second part connected to the first part and having a predetermined length. The screw thread may be formed on all or part of the first part, and the second part may have a groove to which the plug-type wire is connected.
