Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamping devices for electrically coupling sensor cables to electrodes often transmit unfavorable forces and torques, are difficult to disinfect, and are unsuitable for use with 'monoleads' due to geometric constraints, particularly affecting small patients and causing unintended overturning during separation.
Innovation Solution
A clamping device with a circumferentially elastically deformable frame, featuring a contact device and counter-holding device that form a receiving space for the electrode rivet, allowing for easy coupling and uncoupling via different pressure axes, eliminating narrow joints for improved disinfection and reducing torque transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional clamping devices are used to electrically couple sensor cables to electrodes, then electrical coupling is achieved, but unfavorable forces and torques are transmitted to the electrode and patient
Solution Approach 1:
The clamping device is divided into a clamping area with clamping jaws for electrical contact and an actuating area with actuating surfaces for operation. This segmentation allows the electrical coupling function to be separated from the actuation function, enabling reliable electrical contact while minimizing force transmission to the electrode through the designed geometry of the clamping jaws and actuating surfaces.
Solution Approach 2:
The patent introduces multiple axes of operation (first axis for coupling, second axis for uncoupling) that are different from each other. By operating on different axes, the device achieves electrical coupling in one dimension while minimizing torque transmission in another dimension, resolving the contradiction between reliable coupling and harmful force transmission.
2Reliability
If conventional clamping devices are used with electrodes arranged close to one another, then electrical coupling is achieved, but actuating surfaces are difficult to access and unintended overturning torque is transmitted
Solution Approach 1:
The clamping device features asymmetric geometry where the actuating surfaces are positioned and oriented to be easily accessible when electrodes are arranged close together. The actuating area is designed with different characteristics from the clamping area, allowing operators to access actuating surfaces without difficulty even in constrained spaces, while the asymmetric design prevents unintended overturning torque during separation.
3Reliability
If conventional clamping devices are used, then electrical coupling is achieved, but partition lines make disinfection highly complicated
Solution Approach 1:
The patent merges the clamping area and actuating area into a single integrated clamping device without partition lines. This unified structure eliminates the disinfection problems associated with multiple separate components and joining interfaces, allowing simple and effective disinfection while maintaining reliable electrical coupling through the integrated design.
4Reliability
If conventional clamping devices are used, then electrical coupling is achieved, but they are unsuitable for monoleads due to geometric configuration
Solution Approach 1:
The clamping device is designed with universal geometry that can accommodate different cable configurations including monoleads (where multiple cables are combined into an overall cable). The actuating area and clamping area are configured to work effectively with various electrode and cable arrangements, making the device adaptable to different application scenarios while maintaining reliable electrical coupling.

AI summary
A clamping device (1), for coupling a sensor cable (2) to an electrical contact, has a circumferential, elastically deformable frame (3). The frame has an outer surface (5), an inner surface (6) facing an inner area (4), a first end face (7) and an opposite second end face (8). A contact device (9) is held at the frame and extends into the inner area. A counter-holding device (10), at the frame, has a counter-holding element (11). The contact device and the counter-holding device form a receiving space for holding the electrical contact in a holding position. A relative movement into a first released position is brought about by a pressing on both sides from the outside against the outer surface on a first frame axis (12). A second released position is provided by pressing on both sides against the frame outer surface on a second frame axis (13).
