Solution Overview
Problem
Existing transportation plates in dross conveyors for laser beam machines are prone to excessive thermal deformation and compressive plastic strain, leading to hindered smooth movement and reduced durability.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional transportation plate is used in a dross conveyor, then the plate can transport dross, but the plate experiences excessive thermal deformation and compressive plastic strain leading to hindered smooth movement and reduced durability
Solution Approach 1:
The patent applies parameter changes by modifying the plate's structural parameters (adding ribs, changing thickness distribution, optimizing geometry) to alter its thermal and mechanical properties. This reduces thermal deformation and compressive plastic strain while maintaining transport functionality, thereby improving durability and reliability
Solution Approach 2:
The patent segments the plate structure by adding ribs and dividing the plate into different functional zones with varying thickness and stiffness. This segmentation allows different parts of the plate to handle thermal and mechanical loads differently, reducing overall deformation and improving durability
2Reliability
If the transportation plate is designed to reduce thermal deformation, then durability improves, but the design complexity increases
Solution Approach 1:
The patent uses parameter changes to optimize plate design, but applies them systematically through standardized rib patterns and modular design approaches. This reduces the practical design complexity while achieving the goal of reduced thermal deformation and improved durability
Solution Approach 2:
The patent performs preliminary design optimization by pre-calculating and pre-designing rib configurations and plate geometries that inherently resist thermal deformation. This preliminary action embeds the solution into the base design, avoiding the need for complex active control systems or post-manufacturing adjustments

AI summary
A method for designing a transportation plate includes defining a model plate as a basic model of the transportation plate that is configured to transport dross generated by irradiation of a laser beam on a workpiece, acquiring a basic deflection amount that is an amount of deflection of the model plate, defining a first deflection amount as an amount of deflection of the transportation plate, and designing the transportation plate based on the model plate such that the first deflection amount is smaller than the basic deflection amount. The deflection of the model plate occurs due to irradiation of a first laser beam on the model plate. The deflection of the transportation plate occurs due to the irradiation of the first laser beam on the transportation plate under a condition substantially similar to a condition for the irradiation of the first laser beam on the model plate.
