Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joining devices for fluid conveyance and distribution systems, particularly flange connectors for valves, face challenges in achieving a mechanically resistant connection while adhering to standardized dimensions and varying regulatory requirements, making them difficult to install and customize for different markets.
Innovation Solution
A joining device comprising a cylindrical tubular portion with a connection flange, a withdrawal-prevention insert, and a threaded ring nut, which allows for secure flanged attachment by screwing the ring nut, ensuring preset dimensions and mechanical resistance, and can be customized through injection molding and mechanical processing to meet different technical standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If joining devices use welding or gluing to connect tubular portions to valves, then a mechanically resistant connection is achieved, but the connection becomes a mechanically weak point and fails to meet standardized dimensional requirements
Solution Approach 1:
The joining device is divided into separate modular components: a tubular portion, a connection flange, and a withdrawal-prevention insert. These segments can be independently manufactured and assembled, allowing each component to be optimized for its specific function while maintaining overall connection strength and reliability.
Solution Approach 2:
The withdrawal-prevention insert is pre-installed into the tubular portion before final assembly with the valve. This preliminary action prevents the insert from being accidentally removed during installation and ensures proper positioning, thereby maintaining connection reliability without compromising strength.
2Adaptability or versatility
If joining devices are customized for different technical regulations, then adaptability to different markets is improved, but manufacturing complexity and difficulty increase
Solution Approach 1:
The connection flange is designed with universal features that can accommodate different technical regulations and market requirements. Standardized flange dimensions, bolt hole patterns, and connection interfaces allow the same basic design to serve multiple regulatory standards, reducing manufacturing complexity while maintaining adaptability.
Solution Approach 2:
Specific dimensional parameters of the joining device, such as flange diameter, bolt hole spacing, and tubular portion length, can be adjusted to meet different technical regulations. This parameter-based customization allows adaptability to various markets without fundamentally changing the device design or increasing overall manufacturing complexity.
3Adaptability or versatility
If joining devices are customized for different markets, then product adaptability is improved, but large-scale production efficiency decreases
Solution Approach 1:
The joining device components are segmented to allow modular manufacturing. Different parameters can be adjusted during injection molding of individual components without requiring complete redesign or retooling of the entire device, maintaining production efficiency while enabling market-specific customization.
Solution Approach 2:
Injection molding parameters such as dimensional tolerances, wall thickness, and geometric features can be modified to produce different versions of the joining device for various markets. This parameter-based approach allows customization while maintaining efficient large-scale production processes.

AI summary
A joining device (1) for components in fluid conveyance and distribution systems comprises a tubular portion (2); a connection flange (3) obtained as one piece with a first end (4) of the tubular portion (2); one or more seats (5) obtained in an outer surface (6) of the tubular portion (2) in the proximity of a second free end (7) thereof; at least one withdrawal-prevention insert (8) couplable with the seat (5) so as to form a shoulder radially projecting from the outer surface (6); a ring nut (9) having a countershoulder (10) configured so that, once the withdrawal-prevention insert (8) has been disconnected from the seat (5), the ring nut can be inserted onto the tubular portion (2) and extracted therefrom, and, when the withdrawal-prevention insert (8) has been coupled with the seat (5), the withdrawal-prevention insert (8) engages the ring nut (9) countershoulder (10), thus connecting the ring nut in an integral manner, under traction, to the tubular portion (2).
