High Pressure Hose Fitting with Branch Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection fittings for high and ultra-high pressure hoses require large installation spaces, cause pressure losses, and have a high risk of leakage due to their design, which includes multiple sealing points and limited adjustability during assembly.
Innovation Solution
A branch body is arranged between the connection head and the connection body with a connecting bore and branch bore, maintaining a distance from screw bolts, allowing for adjustability and reducing the number of sealing points, while the hose fitting is designed to minimize flow disruptions and enhance accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a traditional connection fitting with solid flange and multiple connection points is used, then connection stability is improved, but overall height increases and installation space requirement worsens
Solution Approach 1:
The connection fitting is divided into separate components: a connection head with integrated branch body, and a separate flange that attaches to the connection body. This segmentation allows the flange to be positioned closer to the pump housing while maintaining stable bolted connections, thereby reducing overall height without compromising connection stability.
Solution Approach 2:
The branch body incorporates flange extensions that protrude laterally from the main body, moving connection points from a vertical arrangement to a horizontal arrangement. This dimensional change allows connections to be made at lower heights while maintaining structural stability through the flange extensions.
2Adaptability or versatility
If multiple connection points are provided for branches, then connection versatility is improved, but number of sealing points increases and leakage risk worsens
Solution Approach 1:
The branch body is designed as a universal component with multiple flange extensions that can accommodate different connection configurations. The same branch body structure provides multiple connection points without requiring additional sealing elements at each point, maintaining reliability while offering connection versatility.
Solution Approach 2:
Multiple connection functions are merged into a single integrated branch body component. Instead of having separate connection elements each requiring their own sealing, the branch body consolidates multiple connection points into one piece with a single sealing interface at the connection head, reducing leakage risk while maintaining versatility.
3Volume of moving object
If the branch body is positioned close to the connection body, then compactness is improved, but accessibility for maintenance worsens
Solution Approach 1:
The flange extensions protrude laterally from the branch body in a direction perpendicular to the main flow path. This dimensional arrangement allows the branch body to be positioned compactly near the connection body while the flange extensions extend outward to provide accessible connection points for maintenance operations.
4Ease of manufacture
If the hole pattern of the flange is fixed, then manufacturing simplicity is improved, but adjustability during assembly worsens
Solution Approach 1:
The flange is designed with a rotating capability relative to the branch body, allowing the hole pattern to be dynamically repositioned during assembly. The flange can be rotated to align its holes with different positions on the connection body, providing adjustability while maintaining a simple fixed hole pattern on the flange itself for ease of manufacture.

AI summary
Connecting fitting comprises a branch body (8) arranged in a sealing manner between a connecting head (3) and a connecting body (7), a connecting hole (9) and branch holes (11) leading to an external connection (12). An independent claim is also included for a branch body for the above connecting fitting. Preferred Features: The branch body has a planar head surface (14) lying with its front surface (13) on the connecting head. A peripheral groove (16) for receiving an O-ring seal (17) is formed in the front surface of the connecting body.
