Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing piping systems with adjusting devices, such as pneumatic control valves, often require multiple components and complex arrangements to transmit forces between outer and inner control elements, leading to increased complexity and sealing challenges.
Innovation Solution
The solution involves using the corrugated pipe wall itself to directly transmit forces between outer and inner adjusting elements through a form-fit contact area, eliminating the need for additional ring elements and simplifying the system by reducing the number of components, thereby enhancing sealing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If an external control element is arranged between two corrugated pipe sections and directly connected to an inner control element, then the force transmission is direct and effective, but the device complexity increases due to multiple components and sealing requirements
Solution Approach 1:
The patent merges the force transmission function into the corrugated pipe wall itself by creating contact areas on the inner control element that directly engage with the corrugated pipe wall. This eliminates the need for separate external control elements and intermediate connection components, thereby reducing device complexity while maintaining effective force transmission from the deformable pipe section to the control element.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components (external control elements, guide rings, and complex sealing arrangements) by utilizing the corrugated pipe wall's inherent structural properties for direct force transmission. The inner control element is designed with contact areas that directly interface with the corrugated pipe wall, removing redundant components and simplifying the overall device structure.
2Strength
If multiple components are used to connect outer and inner control elements, then the structural integrity is maintained, but the sealing difficulty increases
Solution Approach 1:
The patent combines the force transmission and sealing functions into a single integrated solution where the corrugated pipe wall itself serves as both the structural element and the sealing interface. The contact areas on the inner control element directly engage with the corrugated pipe wall structure, eliminating the need for separate sealing components and intermediate connection elements, thereby reducing sealing complexity while maintaining structural integrity.
3Device complexity
If a corrugated pipe wall is used to directly transmit force through form-fit contact areas, then the number of components is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by creating specific contact areas on the inner control element that are adapted to the local geometry of the corrugated pipe wall. Rather than requiring high precision across the entire component, the contact areas are designed to match the specific local features of the corrugated structure, allowing for effective force transmission while tolerating variations in overall manufacturing precision.
