Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the metal material is heated and formed, then the formability is improved, but the strength of the formed product deteriorates
Solution Approach 1:
The metal material undergoes solution treatment and artificial aging treatment before the forming process. This preliminary heat treatment creates a microstructure that can be heated again during forming without losing strength, as the precipitates are already in an optimal state that withstands the heating and forming conditions while maintaining high strength in the final product.
2Strength
If aging treatment is performed after forming, then the strength is improved, but the dimensional accuracy deteriorates
Solution Approach 1:
Artificial aging treatment is performed on the metal material before the forming process. This preliminary aging creates a stable microstructure with precipitates that remain stable during the subsequent heating and forming operations, thereby maintaining high strength while preserving dimensional accuracy without requiring post-forming aging that would cause distortion.
3Ease of manufacture
If the metal material is heated to high temperature, then the formability is improved, but material seizure occurs
Solution Approach 1:
The metal material undergoes solution treatment and artificial aging treatment before forming, which creates a microstructure that remains stable at high temperatures. This preliminary heat treatment prevents material seizure during forming by ensuring the microstructure does not undergo unwanted changes or adhesion to the forming tool at elevated temperatures, while still allowing good formability.
