Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If quantitative extruders frequently switch positions to process different rubber formulations, then multiple rubber formulations can be processed, but production efficiency is reduced due to time-consuming position switching
Solution Approach 1:
Multiple quantitative extruders are merged into a single machine head assembly, allowing different rubber formulations to be processed simultaneously or sequentially without position switching. The machine head integrates multiple extrusion channels, each connected to a dedicated quantitative extruder, enabling the system to handle multiple formulations while maintaining high production efficiency.
Solution Approach 2:
The system transitions from linear position switching to spatial parallelism by arranging multiple extruders in a multi-dimensional configuration within the machine head. This allows simultaneous extrusion of different rubber formulations through different channels, eliminating the time loss associated with sequential position changes.
2Adaptability or versatility
If quantitative extruders are arranged in planar layout to access different positions, then multiple rubber formulations can be processed, but large area is occupied
Solution Approach 1:
Multiple quantitative extruders are nested within a compact machine head assembly, with each extruder positioned in a space-efficient configuration. The nested arrangement allows multiple extrusion channels to be integrated into a single compact unit, significantly reducing the occupied area compared to traditional planar layouts where each extruder would require separate positioning space.

AI summary
The present disclosure provides an extrusion system and a method for processing a tire blank. The extrusion system includes: a base; a moving mechanism mounted on the base and being provided with a mounting frame; an extruder assembly mounted on the mounting frame and including a plurality of extruders; and a main machine head mounted in front of the extruder assembly and being provided with a rubber outlet in communication with machine heads of the plurality of extruders. After one rubber processing is completed, another extruder needing to discharge rubber is selected from the extruder assembly to discharge rubber according to the rubber material to be processed in a next step, and the next working procedure is directly performed. It is unnecessary to repeatedly switch every extruder to the position of the tire blank to be processed to process the tire blank as in the related art, and the operation is simple and the production efficiency is high.
