Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a stationary guide and temperature control device is integrated into the corrugator, then temperature control precision and uniformity are improved, but device complexity increases
Solution Approach 1:
The patent combines the guide device and temperature control device into a single integrated stationary unit that interacts with the mold blocks. The guide surfaces and temperature control surfaces are merged into one structure, allowing simultaneous guidance and thermal regulation functions to be performed by a single component rather than separate systems.
Solution Approach 2:
The stationary guide and temperature control device serves multiple functions: it guides the mold blocks through the corrugator, controls their temperature distribution, and provides structural support. This multi-functional design reduces the need for separate components and simplifies the overall system while improving manufacturing precision.
2Temperature
If temperature control medium channels are added to the guide device, then temperature control capability is improved, but device complexity increases
Solution Approach 1:
The temperature control medium channels are integrated directly into the guide device structure. The channels are formed within the body of the guide and temperature control device, allowing coolant or heating medium to flow through the same component that provides mechanical guidance, eliminating the need for separate temperature control apparatus.
3Manufacturing precision
If guide recesses with elevations and depressions are formed in the temperature control surface, then guidance precision is improved, but manufacturing complexity increases
Solution Approach 1:
The guide surfaces feature localized elevations and depressions that create specific contact points and guidance geometries. These local variations in surface topology provide precise guidance for the mold blocks while maintaining a relatively simple overall device structure. The complex guidance function is achieved through local surface features rather than complex global geometry.

AI summary
A device (10) is described for producing plastic tubing (10), comprising an extruder (9) with an extrusion head (9s) and a corrugator (1), into which a molten plastic tube is fed via the extrusion head (9s) for shaping the plastic tubing (10), wherein: the corrugator (1) has a moulding section (1f) in which moulding jaws (5) are guided in pairs in the production direction; in an inlet section (1e) of the corrugator (1), the moulding jaws (5) are guided together to form a moulding jaw pair at the start of the moulding section (1f); and in an outlet section (1a) of the corrugator (1), the moulding jaw pairs are guided away from one another at the end of the moulding section (1f). An essential feature is that the guide device (6) has a guiding and/or temperature-control body unit (8, 8i), that the guiding and/or temperature-control body unit (8, 8i) has a temperature-control medium channel unit (8k) through which a temperature-control medium can flow, and that the guiding and/or temperature-control body unit (8, 8i) has a guide and/or a temperature-control surface unit which faces the exterior of the passing moulding jaws (5) whilst transmitting heat.
