Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser beam machine conveyors experience thermal deformation of transportation plates due to laser irradiation, leading to hindered smooth movement of the conveyor system.
Innovation Solution
Incorporating a first transportation plate with a concave portion that extends in the direction of laser beam irradiation, opposing thermal deflections at the middle and front end portions to minimize overall deformation, allowing for smooth movement of the conveyor system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat transportation plate is used, then the structure is simple and easy to manufacture, but thermal deformation occurs under laser irradiation causing hindered smooth movement
Solution Approach 1:
The transportation plate incorporates a concave portion in its middle region, transforming the flat surface into a curved geometry. This curvature allows the plate to flex and accommodate thermal expansion under laser irradiation, preventing deformation that would hinder smooth movement while maintaining manufacturing feasibility
2Stability of the object's composition
If the transportation plate is made rigid to maintain stability, then positioning accuracy is improved, but thermal deformation increases under laser irradiation
Solution Approach 1:
The transportation plate is divided into distinct functional zones: a rigid front end portion for stable positioning, a concave middle portion that can flex to accommodate thermal expansion, and connection portions linking them. This segmentation allows different regions to serve different functions - stability where needed and flexibility where thermal stress occurs
Solution Approach 2:
Different portions of the transportation plate have different structural properties. The front end portion maintains rigidity for stable workpiece positioning, while the middle portion incorporates a concave shape that provides flexibility to handle thermal deformation, creating local quality variations that optimize both stability and thermal resistance
