Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional transportation plates are used in laser beam machines, then the structure is simple and cost-effective, but the plates suffer from thermal deformation due to laser beam energy absorption
Solution Approach 1:
The transportation plate is constructed as a composite structure with a base material and a temperature rise prevention surface layer made of copper, copper alloy, aluminum, or aluminum alloy. This composite design combines the structural integrity of the base material with the high thermal conductivity and laser reflectivity of the surface layer, effectively preventing thermal deformation while maintaining structural simplicity
Solution Approach 2:
The invention changes the material parameters of the transportation plate by incorporating materials with high thermal conductivity and high laser reflectivity (copper, copper alloy, aluminum, or aluminum alloy) into the plate structure. This parameter change enables the plate to reflect laser beam energy and conduct heat away efficiently, preventing thermal deformation without complicating the overall structure
2Reliability
If transportation plates are made with high thermal conductivity materials, then thermal deformation is prevented, but the cost of materials increases
Solution Approach 1:
Instead of making the entire transportation plate from expensive high thermal conductivity materials, the invention applies the temperature rise prevention surface made of copper, copper alloy, aluminum, or aluminum alloy only where needed - on the surface that contacts the laser beam and dross. This local application of premium materials prevents thermal deformation at critical areas while keeping overall material costs reasonable
3Temperature
If the transportation plate reflects laser beam energy, then temperature rise is prevented, but the laser beam energy is not fully utilized for dross vaporization
Solution Approach 1:
The temperature rise prevention surface is applied selectively to specific areas of the transportation plate where laser beam reflection is most needed to prevent thermal deformation, while other areas maintain normal laser absorption characteristics. This localized approach ensures the plate stays cool without significantly reducing the laser's ability to vaporize and remove dross
Solution Approach 2:
The invention converts the potentially harmful effect of laser beam energy absorption by the transportation plate into a beneficial effect by using the reflected energy to enhance dross vaporization. The plate's high reflectivity, which initially seemed to reduce energy utilization, actually helps concentrate laser energy on the dross material, improving removal efficiency while keeping the plate temperature low
