Solution Overview
Problem
Articulated link conveyor sliding tracks, especially those with a curvilinear axis and made of plastic, are prone to instability due to thermal variations and tensioning forces, leading to undesired movements and deformation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If plastic sliding tracks are used for articulated link conveyors, then ease of manufacture and corrosion resistance are improved, but structural stiffness and stability deteriorate under thermal variations and tensioning forces
Solution Approach 1:
The patent applies composite materials by combining plastic (polymer) and metal (steel reinforcing elements) to create a hybrid sliding track structure. The plastic component provides corrosion resistance and ease of manufacture, while the embedded steel reinforcing elements provide the necessary structural stiffness and stability, resolving the contradiction between ease of manufacture and structural strength.
2Reliability
If plastic sliding tracks are used for articulated link conveyors, then corrosion resistance and ease of assembly are improved, but stability under thermal variations and tensioning forces deteriorates
Solution Approach 1:
The composite structure maintains the plastic outer layer for corrosion resistance while incorporating steel reinforcing elements to provide dimensional stability under thermal variations and tensioning forces, thus resolving the contradiction between corrosion resistance and structural stability.
3Ease of operation
If traditional plastic sliding tracks are used, then ease of assembly is improved, but deformation under load increases
Solution Approach 1:
The patent maintains the simple assembly process of traditional plastic tracks while significantly reducing deformation under load by embedding steel reinforcing elements within the plastic structure, thus resolving the contradiction between ease of assembly and manufacturing precision.
