Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implantable medical devices require complex connectors with multiple insulated conductors, which become impractical due to space constraints, especially when the number of contacts exceeds certain limits.
Innovation Solution
A compact implantable electrical plug connector design featuring two plug connector parts that angle their contact poles at least 30 degrees, preferably 90 degrees, to reduce spatial requirements and facilitate secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of individual contacts is increased to meet electrical connection requirements, then the electrical connectivity is improved, but the connector length and space requirements increase making it unusable during implantation
Solution Approach 1:
The patent applies dimensional change by arranging contact pole parts in a three-dimensional configuration rather than a linear one. Multiple contact pole parts are positioned at different angles (at least 30 degrees apart) around the longitudinal axis of the plug connector part, allowing numerous electrical contacts to be achieved within a compact longitudinal space. This angular distribution transforms the problem from a one-dimensional linear arrangement to a three-dimensional spatial arrangement, resolving the contradiction between contact number and connector length.
2Adaptability or versatility
If parallel connector poles are used to accommodate multiple conductors, then electrical connectivity is improved, but the connector becomes longer and more complex
Solution Approach 1:
Instead of arranging contact pole parts parallel to each other in a linear fashion, the invention distributes them angularly around the longitudinal axis. This creates a radial or circumferential pattern that accommodates multiple contacts without increasing the linear dimensions or structural complexity of the connector body.
Solution Approach 2:
The contact pole parts are arranged concentrically around the longitudinal axis, with multiple contacts nested within the cylindrical volume of the plug connector part. This nesting approach allows multiple electrical connections to be packed into a compact space without requiring parallel extensions that would increase overall length and complexity.
3Adaptability or versatility
If multi-channel in-line connectors with coaxial contacts are used, then electrical connectivity is improved, but the connector length increases significantly
Solution Approach 1:
The invention fundamentally changes the spatial arrangement from a longitudinal in-line configuration to a radial/angular configuration. Contact pole parts are positioned at angles of at least 30 degrees to each other around the longitudinal axis, transforming the connector from a linear extension into a compact radial structure that achieves multiple contacts without proportional increases in length.

AI summary
The invention relates to an implantable electrical plug connector with two plug connector parts which can be joined together to make electrical contact, one of which is connected to a first line and the other of which is connected to a second line, wherein each plug connector part has at least one or at least two contact pole parts respectively in the form of a contact pin or a contact socket, which can each be plugged together with the contact pole parts of the other plug connector part to make contact, wherein the longitudinal axes of the contact pole parts (plugging direction of the contact pole parts in which they are moved to establish the plug-in connection) extend at an angle of at least 30 degrees, in particular at an angle of 90 degrees, to a longitudinal axis of the first and/or second plug connector part.
