Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump devices, such as orbital pumps, face challenges in securing connections between components, leading to potential leaks and instability during operation, which can affect the efficiency and reliability of fluid transport.
Innovation Solution
The design incorporates a hydraulics housing with an annular portion and lateral sections, where the sections are connected via welds over 70% of the circumference, and a clamping element to ensure a secure and stable assembly, reducing the risk of leaks and facilitating easy installation and centering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump device uses conventional connection methods between components, then the assembly is simpler to manufacture, but the connection stability and leak resistance deteriorate
Solution Approach 1:
The pump device is divided into modular components (pump housing, drive housing, lateral sections) that can be manufactured separately and then assembled. The annular portion with integrated drive flange allows the drive unit to be mounted as a separate module, simplifying manufacturing while maintaining connection stability through precise mating surfaces and welding interfaces.
Solution Approach 2:
The drive flange is merged with the annular portion of the pump housing to form an integrated structure. This combination eliminates the need for separate connection components between the drive unit and pump housing, thereby ensuring stable connections and preventing leaks while actually simplifying the overall assembly process.
2Stability of the object's composition
If the pump device uses conventional housing design without integrated drive flange, then the manufacturing process is simpler, but the installation centering and stability deteriorate
Solution Approach 1:
The drive flange is integrated into the annular portion of the pump housing, creating a unified structure that provides both structural stability and precise centering features for installation. This merger eliminates the need for separate flange components and ensures proper alignment during assembly.
Solution Approach 2:
The annular portion serves multiple functions: it provides the structural housing for the pump mechanism, acts as the drive flange for mounting the drive unit, and includes integrated centering features for precise installation. This multi-functionality enhances installation stability without significantly increasing overall device complexity.
3Reliability
If the pump device uses minimal welding coverage between sections, then the manufacturing cost and time are reduced, but the leak resistance and connection strength deteriorate
Solution Approach 1:
The welding is concentrated at critical locations where leak paths would occur, such as the joints between the annular portion and lateral sections. By applying welding only where necessary rather than uniformly across all surfaces, the design achieves adequate leak resistance while minimizing manufacturing time and cost.

AI summary
Pump device has pump housing with annular portion; a deformable pump ring that defines annular pump chamber; a first connection and a second connection in fluid communication with the-pump chamber; an eccentric rotatable relative to the pump housing and arranged such that the eccentric deforms the-pump ring and pump ring presses against the annular to pump fluid along the-pump chamber from the-first to the-second connection depending on the current rotational position of the eccentric. A clamping element presses the-pump ring against the-annular portion of the pump housing in a clamping link region. The pump ring has at least one recess for accommodating at least part of the clamping element and is dimensioned to provide a distance between the radially inner side of the clamping element and the-pump ring.
