Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for extruded plastic pipes struggle to adapt to varying pipe diameters and geometries, requiring complex designs and adjustments during the extrusion process.
Innovation Solution
A support device with movable elements, including threaded rods and a central adjustment mechanism, allows for radial or curved movement to change the support contour, ensuring comprehensive support and guidance for pipes of different diameters and shapes, which can be adjusted manually or automatically based on measured parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed support device is used for extruded plastic pipes, then the device structure is simple, but it cannot adapt to varying pipe diameters and geometries
Solution Approach 1:
The support device incorporates movable support elements that can dynamically adjust their positions radially towards or away from the extrusion centerline. This dynamic capability allows the device to adapt to different pipe diameters and geometries during the extrusion process, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The support device is divided into multiple individual support elements rather than a single fixed structure. Each element can be independently adjusted, enabling the device to accommodate varying pipe geometries while maintaining a relatively simple overall structure through modular design.
2Adaptability or versatility
If multiple support elements are used to adapt to different pipe geometries, then adaptability is improved, but the device complexity increases
Solution Approach 1:
Each support element is designed with multi-functionality, capable of performing multiple roles through a single adjustment mechanism. The elements can support pipes of different diameters, accommodate various geometries, and maintain contact surfaces that adapt to the profile being extruded, reducing the need for multiple specialized components.
Solution Approach 2:
The adjustment mechanisms for multiple support elements are combined into a centralized control system. This allows simultaneous adjustment of multiple elements through a single control point, reducing operational complexity while maintaining the adaptability benefits of having multiple support elements.
3Productivity
If manual adjustment of support contour is used, then device complexity is reduced, but production efficiency decreases
Solution Approach 1:
The system incorporates measurement systems that provide feedback on the actual pipe dimensions and geometry. This feedback is used by the control system to automatically adjust the support element positions, enabling real-time adaptation during extrusion and significantly improving production efficiency compared to manual adjustment methods.
Solution Approach 2:
The patent replaces manual mechanical adjustment with automated control systems that can be integrated into the overall machine control. This substitution of manual operations with automated control mechanisms increases production speed and efficiency while managing device complexity through integrated control architecture.
