Contact Piece Holder for Slip Ring with Loose Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contact piece holders in electroplating systems often require frequent maintenance and replacement due to dirt and acid residue accumulation, leading to interruptions in electrical energy transmission.
Innovation Solution
A contact piece holder design with a receiving device that allows the contact piece to be loosely clamped between the pressure device and the slip ring, eliminating the need for a housing and enabling easy replacement, and featuring a U-shaped or hook-shaped leaf spring for pressing force application, along with a pivot pin for rotational movement, ensuring uninterrupted electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the contact piece is accommodated in a housing with guiding structures, then the contact piece is guided and positioned correctly, but dirt and acid residues accumulate in the housing causing the contact piece to become jammed or blocked
Solution Approach 1:
The patent removes the housing and guiding structures that were previously used to guide the contact piece. Instead, the contact piece is guided solely by the pressing device and the slip ring surface itself, eliminating the housing where dirt and acid residues accumulated and caused jamming.
Solution Approach 2:
The patent separates the guiding function from the housing structure. The guiding function is now performed by the pressing device and slip ring interface, while the housing is eliminated entirely. This segmentation removes the problematic accumulation zone for contaminants.
2Reliability
If the contact piece holder is frequently serviced and replaced, then uninterrupted electrical energy transmission is ensured, but maintenance costs and system downtime increase
Solution Approach 1:
The design allows the contact piece to self-guide through the pressing device and slip ring interface without requiring housing-guided constraints. This eliminates the jamming problem that necessitated frequent maintenance, allowing the system to operate reliably without regular servicing.
3Force
If a helical spring or spring assembly is used in the pressing device, then continuous pressing force is applied to the contact piece, but the pressing device becomes complex and requires a receptacle or housing
Solution Approach 1:
The patent extracts and eliminates the helical spring, spring assembly, and associated receptacle or housing from the pressing device. The pressing force is applied through a simplified mechanism that does not require these complex spring-based components.
Solution Approach 2:
The pressing device is segmented to eliminate the spring mechanism entirely, using only essential components to apply pressing force. This segmentation removes unnecessary complexity while maintaining the required force application function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces maintenance needs to only when the contact piece is worn out, preventing jamming from dirt and acid residues and ensuring continuous electrical energy transmission, making it suitable for electroplating systems.
Implementation Method 1
The pressing device can have a pressing device which is designed as a leaf spring
Implementation Method 2
the connection device serving to transmit electrical energy to the contact piece, with the contact piece being used by means of the pressing device to form a pressing force for transmitting electrical energy to the slip ring

AI summary
The invention relates to a contact piece holder for a slip ring arrangement (10) in an electro-mechanical machine or the like, wherein the contact piece holder comprises a retaining device, a connecting device and a pressure device. The retaining device is provided to retain the connecting device and the pressure device on a machine. The pressure device is provided to position a contact piece (15) relative to a slip ring (16) on the machine. The pressure device forms a receiving device (31) for the contact piece. The connecting device is provided to transfer electrical energy to the contact piece. The contact piece can be brought into contact with the slip ring by means of the pressure device for the transfer of electrical energy to the slip ring, forming a contact pressure. The receiving device is designed such that the contact piece alone is mounted on the receiving device on an end of the contact piece opposite the slip ring.
