Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional smelting process is used to produce 6063 aluminum alloy, then aluminum materials with good performance can be obtained, but large energy consumption and greenhouse gas emissions occur
Solution Approach 1:
The patent recycles aluminum alloy scrap materials to produce new 6063 aluminum alloy, recovering valuable materials that would otherwise be wasted. This circular approach reduces the need for primary aluminum production through energy-intensive smelting processes, thereby lowering overall energy consumption and greenhouse gas emissions while maintaining alloy performance through controlled recycling processes
Solution Approach 2:
The patent modifies the composition parameters of recycled aluminum alloy by controlling the content of alloying elements (Si: 0.30-0.60 wt%, Mg: 0.40-0.70 wt%, Fe: 0.05-0.20 wt%, Mn: 0.05-0.15 wt%, Cu: 0.05-0.10 wt%, Zn: 0.05-0.15 wt%) to ensure the recycled alloy meets performance requirements. This parameter control enables the use of recycled materials without sacrificing the mechanical properties and corrosion resistance needed for consumer electronics applications

This parameter control enables the use of recycled materials without sacrificing the mechanical properties and corrosion resistance needed for consumer electronics applications
Solution Approach 2:
The patent employs quality control and composition adjustment mechanisms to monitor and regulate the chemical composition of recycled aluminum alloy during the recycling process. By implementing feedback control on alloy element content and impurity levels, the process ensures consistent compliance with national AL6063 standards while maintaining the energy efficiency benefits of recycling
