Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated positioning mechanisms are implemented, then productivity and reliability of gemstone identification improve, but device complexity increases
Solution Approach 1:
The device is divided into distinct functional modules: a light source module that generates the focused beam, a gimbal assembly that provides automated positioning, a recording module that captures optical patterns, and a centering mechanism that ensures proper alignment. Each module operates independently but coordinates through standardized interfaces, enabling automated gemstone identification while maintaining manageable system complexity through modular design
Solution Approach 2:
The gimbal assembly serves multiple functions simultaneously: it positions the light source, centers the gemstone, and maintains proper alignment throughout the recording process. The centering mechanism also functions as part of the positioning system while ensuring optical alignment. This multi-functionality reduces the need for separate dedicated components for each operation, improving productivity without proportionally increasing complexity
2Measurement precision
If manual operation is used, then device complexity is reduced, but measurement precision and reliability deteriorate
Solution Approach 1:
The system incorporates automated feedback mechanisms where the recording module detects the optical pattern, and this information is used to verify proper positioning and alignment. The gimbal assembly and centering mechanism work in conjunction with the recording system to ensure that only properly centered gemstones are recorded, maintaining measurement precision through automated quality control rather than relying on manual operator judgment
Solution Approach 2:
The centering mechanism automatically adjusts the gemstone position to ensure proper alignment with the light source without requiring manual intervention. The system self-regulates the positioning through the interaction between the gimbal assembly, centering mechanism, and recording module, thereby achieving consistent measurement precision while the automation handles the complexity of precise positioning
