Separable Hydraulic Adapter Assembly for Leak-Resistant Hose Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydraulic adapter members have integrally formed pipe bodies and mouthpiece portions, making it difficult or impossible to couple the flange portion to a hydraulic device or replace the hose, thereby hindering workability and leading to potential leaks due to unsuitable screw configurations and interfering bent portions.
Innovation Solution
A hydraulic adapter unit with separable hose connecting and pipe members, featuring a female screw portion on the pipe member to reduce leaks and a tapered design to alleviate stress concentration, allowing independent fixing and improved coupling workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the pipe body and mouthpiece portion are integrally formed, then the structural strength is improved, but the workability for coupling and hose replacement deteriorates
Solution Approach 1:
The hydraulic adapter member is divided into three main segments: the pipe body, the mouthpiece portion, and the flange portion. The mouthpiece portion is further separable from the pipe body through a combining mechanism. This segmentation allows the hose connecting part to be replaced independently while maintaining the structural integrity of the pipe body and flange portion, thus resolving the contradiction between structural strength and workability.
2Ease of repair
If the mouthpiece portion and pipe body are made separable, then the ease of hose replacement is improved, but the risk of leakage increases
Solution Approach 1:
A combining portion acts as an intermediary mechanism between the mouthpiece portion and pipe body. This combining portion includes a male screw portion on the mouthpiece side and a corresponding female screw portion on the pipe body side, creating a threaded connection that provides both separability for maintenance and reliable sealing to prevent leakage during operation.
3Ease of manufacture
If a male screw portion is used for combining, then the ease of assembly is improved, but the leakage risk increases
Solution Approach 1:
Instead of using a male screw portion on the pipe body side, the invention inverts the configuration by placing the female screw portion on the pipe body side and the male screw portion on the mouthpiece portion. This inversion allows the male screw to engage with the female screw in a manner that reduces leakage risk while maintaining ease of assembly, as the male screw portion can be easily threaded into the female screw portion.
4Stability of the object's composition
If the flange portion is integrated with the pipe body, then the structural stability is improved, but the flexibility for independent installation deteriorates
Solution Approach 1:
The flange portion is designed as a separate segment that can be independently installed on the pipe body. This segmentation maintains the structural stability of the overall assembly while providing the flexibility to install or remove the flange portion independently, allowing for easier adaptation to different mounting locations and configurations.

AI summary
A hydraulic adapter unit includes a hose connecting member and a pipe member. The hose connecting member is a substantially cylindrical hose connecting member, and includes: a hose fixing portion positioned at one end side of the hose connecting member and to which the hose is fixed; a first combining portion positioned at the other end side of the hose connecting member; and an intermediate portion linking the hose fixing portion and the first combining portion. The pipe member includes: a substantially tubular pipe body; a second combining portion disposed at the one end side of the pipe body and separably combined to the first combining portion of the hose connecting member; and a flange portion disposed at the other end side of the pipe body and formed so as to project outward in the radial direction of the pipe body and fixed to a hydraulic device.
