Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing portable hydraulic pumps use a single output and input configuration, then the device remains simple and portable, but it is limited to operating only one tool at a time
Solution Approach 1:
The patent implements multi-functionality by providing multiple outputs (first outlet, second outlet, third outlet) on the housing, each capable of connecting to different hydraulic tools. The housing serves as a universal platform that can support various tool configurations simultaneously, allowing the pump to function with single-acting cylinders, double-acting cylinders, or tools with integrated valves through appropriate functional elements
Solution Approach 2:
The patent divides the hydraulic system into segmented channels within the housing, with separate pressure lines leading to different outlets. This segmentation allows independent control and operation of multiple tools from a single pump unit, enabling versatile tool operation without requiring separate pump systems for each tool
2Weight of moving object
If the pump achieves high hydraulic pressures with small dimensions, then portability is improved, but the internal space for channels and components becomes limited
Solution Approach 1:
The patent employs nesting by placing the pressure lines and channels inside the housing structure itself, utilizing the housing walls and internal volume efficiently. The pump elements are positioned within the housing, and the pressure lines are routed through the housing material, creating a compact nested arrangement that maximizes pressure generation capability within minimal external dimensions
Solution Approach 2:
The patent utilizes three-dimensional space optimization by arranging outlets on different faces of the housing and routing channels through the housing volume rather than along a linear path. This spatial arrangement allows multiple pressure lines to coexist within the housing without excessive length, maintaining compact dimensions while providing adequate internal space for high-pressure channel routing

AI summary
The invention relates to portable mobile hydraulic pumps for hydraulically operated tools, having a pancake motor connected to a control device and a pot-shaped housing that accommodates the fluid, having connections for at least one tool on the housing and at least one outlet and one inlet and an eccentric having coupled pump elements and channels in the housing. Said hydraulic pumps are characterized by the simple realization thereof. For this purpose, the housing has two connection pieces having the connections for the at least one tool. First channels connect the pressure sides of the pump elements and respective first outputs of the connection pieces. In the connection piece, a second channel connects a second output and a connection for the tool. Furthermore, in the connection piece, a third channel connects a third output and the interior of the housing. The outputs are located at a distance from each other in a plane. Furthermore, at least one function element is arranged.
