T-Shaped Coupling for Dosage Pump Hydraulic Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosage pump connection devices to hydraulic systems are cumbersome, expensive, and require complex installation procedures, occupying excessive space and protruding from the wall due to their fork-shaped design with mutually opposite and coaxial intake and discharge ports.
Innovation Solution
A T-shaped coupling design with laterally adjacent intake and discharge ports on the same side of the head, featuring a compact T-shaped body with straight and curved channel portions, allowing for easier installation and reduced bulk, using three rings instead of four for connection, and enabling the pump to be positioned closer to the hydraulic system pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If fork-shaped couplings with mutually opposite and coaxial intake and discharge ports are used, then the pump can be connected to the hydraulic system, but the device occupies excessive space and protrudes from the wall
Solution Approach 1:
The patent applies asymmetry by repositioning the intake and discharge ports from a symmetric, mutually opposite configuration to an asymmetric, laterally adjacent configuration on the same side of the head. This asymmetric arrangement allows the pump to be positioned closer to the wall and reduces the bulk required for the coupling, directly addressing the space occupation problem while maintaining connection functionality.
Solution Approach 2:
The invention transitions from a three-dimensional fork-shaped coupling extending perpendicular to the wall to a more compact arrangement where ports are positioned on the same side. This dimensional reconfiguration reduces the projection distance from the wall, effectively utilizing space more efficiently without compromising the connection capability to the hydraulic system.
2Ease of manufacture
If fork-shaped couplings with two channels are used, then the intake and discharge ports can be connected to the hydraulic system, but the coupling shape becomes complex and expensive to manufacture
Solution Approach 1:
The coupling is segmented into distinct functional zones: a body portion housing the channels and a separately attachable head portion. This segmentation allows for simpler manufacturing of each component individually, reducing overall complexity and production cost compared to a monolithic fork-shaped coupling with integrated opposite ports.
Solution Approach 2:
Instead of the conventional approach where the complex fork-shaped coupling is designed to accommodate opposite ports, the invention inverts the design logic by positioning ports adjacently on the same side. This inversion simplifies the coupling geometry, making it easier and more cost-effective to manufacture while still achieving the required connection function.
3Productivity
If four rings are used for connection operations, then the coupling can be securely attached to the head and hydraulic system connectors, but the installation process becomes time-consuming
Solution Approach 1:
The patent merges the connection functions into fewer operations by redesigning the coupling and head interface. Instead of requiring four separate ring attachments, the invention integrates the connection mechanism to achieve secure attachment with fewer components or steps, thereby increasing installation speed while maintaining connection reliability through the unified design.
4Volume of moving object
If the pump is positioned away from the wall to accommodate the coupling, then the hydraulic system pipes can be connected, but the pump occupies more space and protrudes from the wall
Solution Approach 1:
The asymmetric positioning of intake and discharge ports on the same side of the head enables the pump to be installed in a position closer to the wall. This asymmetric configuration provides positioning flexibility by allowing the pump to adapt to wall-mounted installations with limited space, while still maintaining proper connection to the hydraulic system pipes.

AI summary
A device for connecting a dosage pump to a hydraulic system; the pump (11) comprises a hollow body (12) whose head (13) accommodates a vaned element (14) which rotates due to the fluid which arrives from the hydraulic system; the fluid enters the head (13) through an intake port (15) and exits through a discharge port (16); the intake port (15) and the discharge port (16) are connected to appropriately provided corresponding connectors of the hydraulic system by interposition of a coupling (17) inside which an intake channel (18) and a discharge channel (19) for the fluid of the pump (11) are provided. On the head (13), the intake port (15) and the discharge port (16) are formed on a same side and are mutually laterally adjacent. On the coupling (17), which is provided by a substantially T-shaped body, the intake channel (18) and the discharge channel (19) each lie, for a first substantially straight portion (18a, 19a), between a port (20, 21) for connection to the hydraulic system and a curved portion (18b, 19b) in the central part (22) of the coupling (17) and, for a second portion (18c, 19c), with an axis (23, 24) which is transverse with respect to the axis (25, 26) of the respective first portion (18a, 19a), between the curved portion (18b, 19b) and an opening (18d, 19d) designed to face one of the two corresponding ports, the intake port (15) or the discharge port (16), of the head (13). The first portions (18a, 19a) of the two channels (18, 19) are mutually opposite with respect to the central part (22) inside the lateral arms (17a, 17b) of the T-shaped body that forms the coupling (17) and the two second portions (18c, 19c) lie within the central part (22) of the coupling (17).
