Hydraulic Accumulator Separating Device Groove Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic accumulator designs face challenges in simplifying production, reducing costs, and ensuring effective sealing and strength in the attachment of the separating device within the storage housing, particularly under dynamic loads and high pressures.
Innovation Solution
The separating device is accommodated in a groove-like depression of one housing part with a holding device applying a defined contact pressure through an independent pressing part, allowing separate manufacturing and easy assembly, ensuring a force-fitting and sealing connection without additional adhesives or complex assembly steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the separating device is attached using an annular bead held between housing parts in groove-shaped recesses, then the sealing and strength under high pressure are improved, but the manufacturing complexity and production time increase due to additional work steps
Solution Approach 1:
The invention extracts the bead formation step from the separating device manufacturing process. Instead of forming an annular bead on the separating device and holding it between housing parts, the patent uses a simple rim structure that is directly received in a groove of the housing, eliminating the need for bead formation and reducing manufacturing complexity while maintaining sealing and strength
Solution Approach 2:
The housing is segmented into first and second housing parts with a groove formed in one of them. The separating device with its rim structure is received in this groove, creating a segmented assembly approach that simplifies manufacturing compared to the integrated bead formation approach, while still providing the necessary sealing and structural support under high pressure
2Reliability
If the separating device is designed with an annular bead for attachment, then the sealing under high pressure is improved, but the production time and costs increase
Solution Approach 1:
The patent removes the time-consuming bead formation operation from the manufacturing process. The separating device is produced with a simple rim structure that requires no additional forming steps, and this rim is directly received in a housing groove, significantly reducing production time while maintaining the sealing performance needed for high-pressure applications
Solution Approach 2:
The groove in the housing automatically provides the sealing and positioning function that previously required a formed bead on the separating device. The rim of the separating device simply needs to fit into the groove, and the groove structure itself provides the necessary sealing and mechanical support, eliminating the need for complex bead formation operations
3Strength
If the separating device is pushed into a bead-shaped connecting part fixed by a clamping ring, then the attachment strength is improved, but the assembly complexity and production time increase
Solution Approach 1:
The invention removes the bead-shaped connecting part and clamping ring from the assembly. Instead, the separating device with its simple rim structure is directly received in a groove of the housing, eliminating the need for these additional components and simplifying the assembly process while maintaining attachment strength
Solution Approach 2:
The housing groove combines multiple functions into a single structure: it provides mechanical support, sealing, and positioning for the separating device. This merged structure eliminates the need for separate bead-shaped connecting parts and clamping rings, reducing assembly complexity while maintaining the necessary attachment strength
4Reliability
If additional components like clamping rings and bead-shaped connecting parts are used, then the attachment reliability under dynamic loads is improved, but the manufacturing costs and production time increase
Solution Approach 1:
The patent extracts and eliminates the additional components (clamping rings, bead-shaped connecting parts) from the design. The housing groove alone provides the necessary attachment reliability under dynamic loads, and the simple rim structure of the separating device fits directly into this groove, significantly reducing production efficiency requirements while maintaining reliability
