Modular Hydraulic Pump Housing with Selective Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricant and hydraulic pumps are costly to manufacture due to complex structures with many components and are inflexible in adapting to varying application requirements, limiting their possible uses.
Innovation Solution
The use of structurally identical housing shells with multiple openings closed by predetermined breaking points allows for reduced component inventory, simplified assembly, and adaptability, enabling cost-effective production and versatile use by varying the number of pump elements and configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different housing shells are used to accommodate varying numbers of pump elements, then the pump can be adapted to different application requirements, but the number of components increases and manufacturing cost rises
Solution Approach 1:
The patent applies universality by designing a single housing shell that can accommodate varying numbers of pump elements (1 to 12) through multiple openings. This universal housing design eliminates the need for multiple different housing shells, reducing component inventory while maintaining adaptability to different application requirements.
Solution Approach 2:
The housing shell is segmented into multiple openings (first, second, third, and fourth openings) that can be selectively opened or closed. This segmentation allows the same housing to be configured for different numbers of pump elements by controlling which openings are accessible, enabling versatility without increasing component count.
2Adaptability or versatility
If multiple different housing shells are used to accommodate varying numbers of pump elements, then the pump can be adapted to different application requirements, but manufacturing cost increases
Solution Approach 1:
By designing a single universal housing shell that can accommodate 1 to 12 pump elements through selective opening/closing of openings, the patent eliminates the need to manufacture and inventory multiple different housing shell variants. This significantly reduces manufacturing costs while maintaining full adaptability to different application requirements.
3Ease of operation
If openings in housing shells are left open for assembly, then pump elements can be installed, but sealing complexity increases requiring separate sealing plugs
Solution Approach 1:
The housing shell is pre-designed with openings that have integrated sealing mechanisms. The sealing function is built into the housing structure itself before assembly, eliminating the need for separate sealing plugs. This preliminary integration of sealing functionality simplifies the overall sealing structure while maintaining ease of assembly.
4Reliability
If individual openings are closed with separate sealing plugs, then sealing is achieved, but construction complexity increases
Solution Approach 1:
The patent merges the sealing function with the housing shell structure itself. The openings are designed to provide sealing through the housing's own structure rather than requiring separate sealing plugs. This merging of functions reduces construction complexity while maintaining sealing reliability.

AI summary
The invention relates to a lubricant or hydraulic pump for delivering oil or the like having a housing (1) which is formed from two housing shells (2, 3) which are of at least substantially similar or identical construction. An inlet (7) is provided on or in the housing (1). Furthermore, a rotatably mounted drive element, which is configured, in particular, as a swash plate (17), and at least one pump element (5) which interacts with the drive element (17) to deliver oil or the like are arranged in the housing (1).
