Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the screening machine is designed with large separation area and operational capacity, then waste separation efficiency is improved, but the machine size becomes too large for efficient transportation on public roads
Solution Approach 1:
The screening machine is divided into modular units that can be detached and transported separately. The conveyor belt system is segmented into multiple sections that can be folded or disconnected, allowing the machine to be broken down into smaller components suitable for standard road transportation without requiring specialized convoys.
Solution Approach 2:
The machine incorporates movable and adjustable components, particularly the conveyor belt system with hydraulic actuators that allow the separation area to be extended during operation and retracted or folded for transportation. This dynamic configuration enables the machine to adapt between operational and transport states.
2Area of stationary object
If the conveyor belt is extended to increase separation area, then waste separation capacity is improved, but the machine complexity increases
Solution Approach 1:
Hydraulic actuators are used to extend and retract the conveyor belt sections, providing a relatively simple and reliable mechanism for adjusting the separation area. The hydraulic system allows for controlled extension of the conveyor belt to increase separation capacity while maintaining manageable complexity through standardized hydraulic components.

AI summary
The subject of the invention is a screening machine unit used to separate waste. The screening machine unit containing a frame (1) with the infeed conveyor (1b) attached in a rotary manner, with the conveyor belt (2) located below the infeed conveyor, characterised in that the conveyor belt (2) is attached to the infeed conveyor (1b) using the engaging half-frames (3) with the running rollers (4), which are connected stationary with the infeed conveyor (1b) using a removable screw connection. They are connected with the conveyor belt (2) in a sliding manner using the linear extension system containing the rollers (4) and the guide assembly (6), constituting the left guide (5L) and the right guide (5P) connected in a sliding manner with the conveyor belt (2). The linear movement of the conveyor belt (2) along the right guide (5P) and the left guide (5L) constitutes the size of the area of separation (2.1) relative to the infeed conveyor (1b). The hydraulic actuator (H1) is located between the engaging half-frames (3) and the guide assembly (6), and the second hydraulic actuator (H2) is located between the guide assembly (6) and the conveyor belt (2).
