Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional integrated laboratory systems use fixed conveyor paths and robotic arms for material transport, then automation and throughput are improved, but flexibility and adaptability to workflow changes deteriorate
Solution Approach 1:
The system replaces fixed conveyor paths with mobile robots that can dynamically change their movement paths and positions. The robots navigate freely within the workspace using fiducial markers for localization, allowing the system to adapt to different instrument layouts and workflow requirements without physical reconfiguration.
Solution Approach 2:
The mobile robots serve multiple functions: they transport materials between instruments, navigate to different workspace locations, and can be remotely controlled or operated autonomously. This universal approach replaces specialized fixed conveyors with multi-functional mobile units that can handle various transport tasks.
2Measurement precision
If conventional systems require recalibration when instrument positions change, then measurement precision is maintained, but system complexity and time required for modifications increase
Solution Approach 1:
The mobile robots perform self-localization by detecting fiducial markers in the workspace. When instrument positions change, the robots automatically update their understanding of the workspace layout by recognizing the markers, eliminating the need for manual recalibration by operators.
Solution Approach 2:
The system replaces mechanical calibration mechanisms with optical/marker-based localization. Instead of physically calibrating robot positions relative to instruments, the system uses vision-based detection of fiducial markers to determine positions, simplifying the modification process.
3Adaptability or versatility
If conventional integrated systems use expensive robotic arms for universal material handling, then adaptability to different instruments is improved, but cost increases
Solution Approach 1:
The system uses relatively simple mobile robots with omnidirectional wheels instead of expensive industrial robotic arms. These simpler robots achieve sufficient adaptability through software-based navigation and control, reducing the cost of the automation system while maintaining versatility.
Solution Approach 2:
The system replaces complex mechanical robotic arms with mobile robots that use omnidirectional wheel mechanisms. The adaptability previously achieved through complex mechanical degrees of freedom is now achieved through software control and navigation algorithms, reducing mechanical complexity and cost.
4Reliability
If conventional systems require service representatives to visit sites for component repairs, then reliability is maintained, but downtime and loss of productivity increase
Solution Approach 1:
The mobile robots can be remotely controlled by operators or automatically navigate to service areas for maintenance. This allows service personnel to work on robots remotely or with minimal site presence, reducing the need for extended service representative visits and minimizing downtime.
Solution Approach 2:
The system enables remote operation and monitoring capabilities that act as intermediaries between the physical robot and service personnel. This allows diagnostics, control, and even certain repairs to be performed remotely, reducing the need for service representatives to physically visit the site and minimizing operational downtime.
