Screw Connection Sealing for Hygienic Multi-Diameter Fittings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screw-connection systems for long-shaped parts with terminal geometry are either complex and expensive to install or require adaptation to different diameters, lacking simplicity and hygiene compliance in hygienically sensitive areas like food production.
Innovation Solution
A screw-connection system featuring a pressure element with a contact-wall section and a seal with both axial and radial seal surfaces, eliminating the need for additional components like washers by integrating a seal between the terminal fastener and pressure-element terminal, ensuring secure and hygienic sealing without diameter adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seal insert and sleeve are added to achieve sealing, then sealing reliability is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent combines the sealing function with the terminal part by integrating a seal directly into the terminal part structure. The seal is positioned between the terminal fastener and the pressure element, eliminating the need for separate seal inserts and sleeves while maintaining reliable sealing between mating surfaces.
2Adaptability or versatility
If additional components like washers are used to adapt to different diameters, then adaptability is improved, but device complexity and installation cost increase
Solution Approach 1:
The terminal part design with integrated seal creates a universal connection system that can accommodate different long-shaped part diameters without requiring additional adaptive components. The sealing mechanism works effectively across various diameters through the integrated seal structure, eliminating the need for washers or other diameter-adaptation components.
3Ease of operation
If a simple connection system is used to reduce complexity, then ease of installation is improved, but sealing reliability and hygiene compliance deteriorate
Solution Approach 1:
The patent merges the sealing function directly into the terminal part structure, creating a simple two-component system (terminal part and pressure element) that is easy to install while ensuring reliable sealing. The integrated seal is positioned to create effective sealing surfaces between the terminal fastener and pressure element without requiring additional sealing components.

AI summary
A screw-connection system for connecting a long-shaped part with a terminal geometry includes at least a pressure element, a terminal part, and a seal. The pressure element has at least one contact-wall section with a contact surface. The seal has at least one outer radial-seal surface and at least one axial-seal surface. The outer radial-seal surface of the seal interacts in a sealing manner at least partially with the contact surface of the contact-wall section and the axial-seal surface is configured at least for partial sealing with the terminal geometry.
