Pipe Fitting Structure With Separate Compression and Sealing Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional small-diameter pipe connectors experience shape deformation due to load, angle changes, and external forces, leading to instability in fixing pipes and difficulty in maintaining airtightness.
Innovation Solution
A fitting apparatus with a fitting unit that includes a first body and a second body, each with recessed grooves for a compression member and a sealing member. The compression member is designed to securely fix the pipes, while the sealing member maintains airtightness between the fitting unit and the pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a water stop ring with elasticity is used in conventional small-diameter pipe connectors, then the connector can be simple in configuration, but shape deformation occurs easily due to load and external forces, leading to unstable pipe fixation
Solution Approach 1:
The connector is divided into multiple functional segments: a rigid body structure providing structural support, a compression member (independent of the water stop ring) dedicated to pipe fixation, and a sealing member (water stop ring) dedicated to airtightness. This segmentation allows each component to perform its specific function without compromising overall stability.
Solution Approach 2:
The compression member is designed to be compressible or deformable under axial load, enabling it to adapt to pipe dimensions and maintain stable fixation. The dynamic compression mechanism allows the rigid body structure to exert controlled force on the pipe through the compression member, ensuring stable pipe fixation while maintaining overall connector simplicity.
2Stability of the object's composition
If a separate fixing apparatus is added to compensate for water stop ring deformation, then pipe fixation stability is improved, but the device complexity and installation time increase
Solution Approach 1:
The functions of pipe fixation and airtightness are merged into a single integrated connector structure. The compression member and sealing member work together within the same connector body, eliminating the need for separate fixing apparatus while maintaining stable pipe fixation. This integration reduces device complexity and installation time.
Solution Approach 2:
The connector body serves multiple functions: providing structural support, housing the compression member for pipe fixation, and accommodating the sealing member for airtightness. This multi-functionality eliminates the need for additional separate fixing devices, maintaining stability while reducing overall device complexity.
3Ease of operation
If the water stop ring is made elastic to fit pipes, then installation ease is improved, but shape deformation occurs under load, compromising airtightness
Solution Approach 1:
The sealing function is separated from the deformation-prone compression function. The sealing member (water stop ring) is positioned downstream from the compression member, in a region less susceptible to deformation. This segmentation allows the sealing member to maintain reliable airtightness while the compression member handles the mechanical load and deformation.
Solution Approach 2:
The compression member acts as an intermediary between the rigid body structure and the sealing member. It transmits the compressive force to the pipe while protecting the sealing member from direct deformation, ensuring that the sealing member maintains its shape and airtightness function even under load.
