Snap-in Rotary Drive Assembly Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of rotary drive devices with swivel pistons is laborious and time-consuming, especially in series production, due to the complexity of handling multiple elements that require precise assembly to prevent the space divider and stop unit from falling apart.
Innovation Solution
The implementation of a snap-in connection mechanism between the space divider element and the stop element allows for a pre-assembled coherent assembly module, eliminating the need for external influence to maintain cohesion, enabling quicker and more cost-efficient assembly by fixing the stop elements to the space divider element using snap-in connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple elements (space divider element and stop element) are assembled before installation, then the assembly module is coherent and stable, but the handling becomes more complex and laborious
Solution Approach 1:
The patent combines the space divider element and stop element into a single integrated assembly module using a snap-in connection mechanism. The stop element features a U-shaped cross-section that envelops the space divider element, creating a unified structure that is handled as one unit during installation, thereby improving stability while simplifying handling procedures
2Stability of the object's composition
If multiple elements are assembled before installation, then cohesion is maintained, but assembly time increases due to careful handling requirements
Solution Approach 1:
The stop element is designed with pre-formed snap-in connection features (protrusions and recesses) that enable quick assembly with the space divider element before installation. This preliminary structuring allows for rapid cohession of the assembly module without requiring time-consuming careful handling during the assembly process
3Adaptability or versatility
If stop element is separate from space divider element, then flexibility in assembly is provided, but the unit may fall apart during installation
Solution Approach 1:
The stop element is designed with a U-shaped cross-section that segments into three portions: two side walls that flank the space divider element and a bottom wall that closes the U-shape. This segmentation allows flexible assembly while the interlocking snap-in connections maintain structural integrity during installation
Solution Approach 2:
The space divider element is nested within the U-shaped stop element, with the stop element's side walls enveloping the space divider element. This nested configuration provides structural integrity during installation while maintaining assembly flexibility through the snap-in connection mechanism

AI summary
A fluid-actuated rotary drive device is provided, with a housing (2) in which is formed a working chamber (3), in which is a swivel piston (18) able to swivel around a central axis (5). Also fitted or able to be fitted in the working chamber (3) is a space divider and stop unit (38), comprised of a space divider element (24) and at least one stop element (42) fixed to the former. The components of the space divider and stop unit (38) are fitted to one another by snap-in connection, so that the space divider and stop unit (38) is easy to handle during its installation in the working chamber (3).
