Slipring Housing Bayonet Lock Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slipring devices face challenges in easy integration into complex environments and require high effort for disassembly during maintenance due to complex assemblies and numerous screws, lacking efficient sealing and easy assembly/disassembly solutions.
Innovation Solution
A slipring device design featuring a rotatable first and second part with a sliding contact connection, utilizing a hollow shaft with bayonet lock notches and a locking ring for simple assembly and disassembly, along with a spring for constant pressure, and optionally 3D printing for integrated springs and parts, allowing easy integration and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robust multifunctional slipring housing with high sealing is used, then protection against dust, debris, and liquids is improved, but the number of screws required for opening the housing increases, making disassembly difficult
Solution Approach 1:
The housing is divided into multiple parts (first housing part and second housing part) that can be separated from each other. The locking mechanism uses a locking element with a locking arm that engages with a locking recess, allowing the housing parts to be securely connected yet easily separated by actuating the locking element, thus resolving the contradiction between robust sealing and easy disassembly.
2Stability of the object's composition
If a complex interior assembly with multiply screwed housing is used, then structural stability is improved, but disassembly requires extremely high efforts
Solution Approach 1:
The locking function is extracted from a complex screw-based system and concentrated into a single locking element with a locking arm and locking recess. This simplified locking mechanism maintains structural stability during operation but allows for easy disassembly by simply actuating the locking element, eliminating the need for multiple screws and extremely high disassembly efforts.
3Strength
If multiple screws are used to secure the housing, then connection strength is improved, but the time required for assembly and disassembly increases
Solution Approach 1:
Multiple screw connections are merged into a single locking element that provides equivalent or superior connection strength. The locking element with its locking arm engaging the locking recess creates a secure connection that maintains structural integrity during operation, while allowing assembly and disassembly to be completed in a single action rather than requiring multiple screws to be tightened or loosened.
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
The design enables straightforward integration and disassembly of slipring devices, providing robust sealing and reduced maintenance efforts while allowing for easy assembly and disassembly, enhancing usability in complex environments.
Implementation Method 1
there is a spring between the locking ring and the first and/or second part to ensure a certain and preferably a constant pressure between the first and the second part to hold these parts in place
Implementation Method 2
The slipring components in the first part and the second part are designed such that they interface in a way to form a sliding contact connection

AI summary
A slipring device comprises a first part and a second part rotatable against each other. Both parts comprise housings with slipring components. A first housing at the first part has a hollow shaft with a bayonet lock notch to engage with a locking ring having at least one bayonet lock protrusion. The locking ring can easily be attached by a bayonet lock to lock the first part and the second part together.
