Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to determine ore-forming environment, then the process is complex and time-consuming, but the determination accuracy is insufficient
Solution Approach 1:
The patent transforms the determination of ore-forming environment from a complex multi-parameter geological analysis into a simplified measurement based on tourmaline trace element parameters (Li, Be, Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, Ge, Rb, Sr, Y, Zr, Nb, Sn, Sb, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, Pb, Th, U). By focusing on specific chemical parameters in tourmaline, the method achieves rapid and accurate discrimination between subduction and collision environments without requiring complex geological field work.
Solution Approach 2:
The patent replaces traditional mechanical field-based geological determination methods with an analytical chemistry approach using LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry). This substitution allows for rapid in-situ analysis of trace elements in tourmaline, providing quick and accurate environmental determination without time-consuming field mapping and geological reasoning.
2Productivity
If comprehensive geological analysis is performed, then the determination is thorough, but the efficiency is low
Solution Approach 1:
The patent extracts the key diagnostic information from complex geological systems by focusing specifically on trace element compositions in tourmaline minerals. Instead of analyzing entire rock samples or performing comprehensive geological surveys, the method isolates and measures only the relevant tourmaline trace elements that carry environmental signatures, achieving both high efficiency and reliability.
Solution Approach 2:
The patent applies local quality by focusing analysis on specific minerals (tourmaline) within the rock that contain the environmental information, rather than analyzing the entire rock sample uniformly. The in-situ LA-ICP-MS technique targets specific tourmaline grains, extracting localized chemical information that reflects the ore-forming environment with high precision and efficiency.
