Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used for preparing samples, then operation simplicity is maintained, but productivity is reduced and processing time increases
Solution Approach 1:
The system enables automated self-service sample preparation where the robotic arm autonomously loads sample containers, the processing mechanism automatically grinds/crushes samples, and the cover mechanism secures containers without manual intervention, thereby increasing productivity and reducing processing time
Solution Approach 2:
Manual mechanical operations are replaced with an automated robotic system that uses a robotic arm for loading, an automated processing mechanism for grinding/crushing, and an automated cover mechanism for securing samples, transforming manual labor into automated mechanical processes
2Manufacturing precision
If excessive processing is applied to grind samples thoroughly, then manufacturing precision is improved, but temperature increases causing sample damage
Solution Approach 1:
The processing mechanism applies periodic grinding/crushing action with optimized stroke length, alternating between processing phases and rest phases that allow heat dissipation, thereby achieving thorough sample preparation while preventing excessive temperature buildup that could damage samples
Solution Approach 2:
The system optimizes processing parameters including stroke length, processing duration, and intensity to achieve the necessary grinding quality while maintaining temperature within safe limits for sample integrity
3Reliability
If sample containers are not securely mounted, then ease of operation is improved, but reliability is reduced
Solution Approach 1:
The cover mechanism automatically secures sample containers through automated engagement with the frame, eliminating the need for manual mounting operations while ensuring reliable and consistent container security through repeated mechanical engagement
