Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for pipe extrusion require separate tools for calibration, sealing, guiding, and clamping, which are not adaptable to varying profile cross-sections during the extrusion process.
Innovation Solution
A device comprising two parts with adjustable contact surfaces that enclose the profile, allowing for sealing, guiding, and clamping functions, with the ability to adjust to different cross-sections through rotation and central machine control, enabling online adaptation to new profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate tools are used for calibration, sealing, guiding, and clamping in pipe extrusion, then each function can be performed with dedicated equipment, but the device complexity increases and adaptability to varying profile cross-sections decreases
Solution Approach 1:
The patent combines multiple separate tools (calibration device, sealing device, guiding device, and clamping device) into a single integrated extrusion device. The housing contains all these functional elements working simultaneously on the profile, eliminating the need for separate tools and reducing overall device complexity while maintaining functional reliability.
Solution Approach 2:
The extrusion device is designed with multi-functional capability to perform calibration, sealing, guiding, and clamping operations within a single device. The housing and its components are configured to execute multiple functions concurrently, making the device universal and adaptable to various profile cross-sections without requiring tool changes.
2Ease of manufacture
If fixed contact surfaces are used in the extrusion device, then the structure is simple, but the adaptability to different profile cross-sections is limited
Solution Approach 1:
The contact surfaces of the housing are designed to be adjustable rather than fixed. The housing can be moved along the extrusion direction and positioned at different locations, allowing dynamic adaptation to various profile cross-sections. This dynamic capability enables the same device to handle different profile sizes and shapes while maintaining reasonable structural simplicity.
3Reliability
If multiple separate tools are provided for extrusion functions, then each function can be optimized independently, but the loss of time for tool changes and adjustments increases
Solution Approach 1:
By merging calibration, sealing, guiding, and clamping functions into a single integrated device, the patent eliminates the time required to change between separate tools. All functions are available simultaneously within the housing, allowing immediate transition between different profile cross-sections without tool changes, thus reducing time loss while maintaining functional capability.
4Reliability
If the contact surfaces are designed to enclose the profile completely, then sealing and guiding functions are improved, but the device complexity and adjustment mechanisms increase
Solution Approach 1:
The housing contact surfaces are designed with local quality variations to achieve effective sealing and guiding without complete enclosure. The contact surfaces are positioned and shaped to provide sufficient local contact for sealing and guiding functions, avoiding the complexity of fully enclosing the profile while maintaining reliable performance where needed.
