Self-Supporting Modular Slipring Structure Without a Central Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slipring modules are inflexible and require a central hollow tube that needs to be adapted to different configurations, making them costly and difficult to assemble without a support shaft or tube.
Innovation Solution
A self-supporting slipring module structure using electrically insulating support blocks with connecting means, such as struts, that form a rigid and torsion-resistant structure without a central axis or shaft, allowing for easy configuration and assembly without the need for a fixed-length tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a central hollow tube is used to support slipring modules, then structural support is provided, but adaptability to different configurations is reduced and manufacturing complexity increases
Solution Approach 1:
The slipring module is divided into multiple individual support blocks that can be independently configured and stacked. Each support block can be designed with different characteristics (conductive, insulating, magnetic, non-magnetic) and assembled in various sequences to create different configurations. This segmentation eliminates the need for a single fixed-length hollow tube while maintaining structural support through the distributed support blocks.
2Stability of the object's composition
If a fixed-length hollow tube is used, then structural stability is achieved, but manufacturing cost and difficulty increase due to customization requirements
Solution Approach 1:
A standardized support block design is created that can serve multiple functions and configurations. The same basic support block structure can be used with different materials (conductive, insulating, magnetic, non-magnetic) and assembled in various combinations to meet different requirements. This universal design eliminates the need for custom-made hollow tubes for each configuration, significantly reducing manufacturing complexity and cost while maintaining structural stability.
3Strength
If a support shaft or tube is used, then mechanical support is provided, but internal space is blocked and assembly complexity increases
Solution Approach 1:
The continuous support shaft or tube is segmented into discrete support blocks distributed throughout the module. This segmentation creates gaps and open spaces between the support blocks that can be utilized for wiring, additional rotary joints, optical joints, RF joints, or media joints. The mechanical support function is maintained through the distributed support blocks while the internal space is freed up for other components.
4Adaptability or versatility
If modular support blocks are used without a central tube, then adaptability and ease of assembly improve, but structural stability may be compromised
Solution Approach 1:
Multiple support blocks are combined and stacked together to form a collective support structure that achieves the required structural stability. The support blocks can be connected through various means (mechanical interlocking, adhesives, or integration with conductive rings) to create a unified stable structure. This merging of multiple discrete blocks provides both the adaptability of modular configuration and the stability of a cohesive structure.

AI summary
A support block configured to form a self-supporting modular slipring module that includes an electrically insulating material and is configured to hold at least one sliding track. The support block includes a generally disk-shaped body having a center opening or bore at a center axis and connecting means, at the body, that are configured to form a fixed connection with at least another similarly structured support block. In one specific non-limiting case, the connecting means includes 6 protrusions with 3 protrusions of a first type and 3 protrusions of a second type, alternatingly arranged. Protrusion of the first type have extending protrusion at their ends, protrusions of the second type have recesses at their ends, and the extending protrusions are dimensioned to fit into the recesses by a press fit.
