Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional die casting process is used to manufacture faucet body, then the faucet body can be produced with minimal wall thickness, but the process introduces foreign particles and impurities into the finished product
Solution Approach 1:
The faucet body is divided into multiple separate components (first faucet portion and second faucet portion) that are manufactured independently and then joined together through laser welding. This segmentation allows each component to be produced with precise wall thickness control while avoiding the introduction of impurities associated with conventional die casting of the entire body.
Solution Approach 2:
The conventional die casting process is replaced with laser welding technology. Instead of injecting molten metal into a mold (mechanical casting process), the invention uses laser energy to join pre-manufactured components, eliminating the harmful effects of molten material processes that introduce impurities.
2Productivity
If conventional die casting process is used, then the faucet body can be manufactured quickly, but excessive material is used leading to increased waste
Solution Approach 1:
The wall thickness parameter is optimized by manufacturing separate faucet portions with precise thickness control through laser welding, rather than using the minimum wall thickness required by die casting processes. This allows for reduced material usage while maintaining structural integrity and manufacturing efficiency.
3Loss of substance
If conventional die casting is used to achieve minimal wall thickness, then material usage is reduced, but the structural strength of the faucet body is compromised
Solution Approach 1:
By segmenting the faucet body into multiple portions joined by laser welding, the invention achieves both minimal material usage and structural strength. The laser welding process creates strong joints between components while allowing each component to be optimized for minimal thickness, thereby reducing overall material usage without compromising strength.
4Ease of manufacture
If conventional die casting process is used, then the manufacturing process is simple, but post-fabrication rejection rate is high due to impurities
Solution Approach 1:
The invention replaces the conventional die casting process with laser welding technology. Although laser welding requires precise positioning and control, it eliminates the introduction of impurities and foreign particles that cause high rejection rates in die casting, thereby improving product reliability and reducing post-fabrication rejections.
