Solution Overview
Problem
Conventional small-diameter pipe connectors face challenges in maintaining airtightness due to shape deformation under load and external forces, requiring additional fixing apparatuses that complicate installation and increase construction time and cost.
Innovation Solution
A fitting apparatus with a compression member and sealing member that form recessed grooves and extensions to securely insert and fix pipes, enhancing airtightness without the need for separate fixing devices, featuring a tubular design with recessed grooves and extensions to ensure stable pipe connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a water stop ring with elasticity is used in conventional small-diameter pipe connectors, then the pipe can be inserted and connected, but shape deformation occurs easily due to load and external forces, making it difficult to stably fix the pipe
Solution Approach 1:
The invention changes the physical state of the sealing component from elastic (conventional water stop ring) to rigid with elastic deformation capability (resilient material). The resilient sealing ring maintains its shape under load while still providing sealing, eliminating the deformation problem of conventional elastic rings. This parameter change resolves the contradiction by maintaining ease of connection while achieving stable pipe fixation.
2Reliability
If a separate fixing apparatus is installed to compensate for the instability of the water stop ring, then pipe fixation stability is improved, but the installation becomes troublesome and construction time and cost increase
Solution Approach 1:
The invention merges the sealing function and the fixation function into a single integrated component - the resilient sealing ring. This ring simultaneously provides sealing (preventing leakage) and fixation (stabilizing the pipe connection) through its elastic deformation capability. By combining these functions, the invention eliminates the need for separate fixing apparatus while maintaining reliable pipe fixation, thus resolving the contradiction between reliability and device complexity.
3Reliability
If a separate fixing apparatus is installed to ensure pipe stability, then fixation reliability is improved, but construction time and cost increase
Solution Approach 1:
The invention integrates sealing and fixation functions into one component, the resilient sealing ring, which is installed simultaneously with the pipe connection. This eliminates the need for sequential installation of separate fixing apparatus, thereby reducing construction time while maintaining fixation reliability. The single-component solution resolves the contradiction between reliability and time loss.
4Reliability
If a separate fixing apparatus is installed to maintain pipe stability, then fixation reliability is improved, but installation cost increases
Solution Approach 1:
The invention combines sealing and fixation functions into a single resilient sealing ring component, eliminating the need for multiple separate parts (sealing ring plus fixing apparatus). This reduction in component count simplifies manufacturing processes and reduces material costs while maintaining reliable pipe fixation. The integration resolves the contradiction between reliability and manufacturing cost.
