Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If external navigation and centralized control are used, then sample distribution can be achieved, but flexibility and autonomy are reduced
Solution Approach 1:
The sample carrier is equipped with its own control entity, code recognition means, and wireless communication means, enabling it to autonomously recognize its position, receive and execute transport tasks, and navigate without external navigation infrastructure. This self-service capability grants full autonomy while eliminating the need for complex external control systems.
Solution Approach 2:
The sample carrier integrates multiple functions into a single device: it carries samples, recognizes position codes, processes wireless communications, controls its own movement, and avoids collisions. This multi-functionality achieves high autonomy without requiring separate external systems for each function.
2Productivity
If self-propelled carriers with autonomous navigation are implemented, then flexibility and efficiency are improved, but device complexity increases
Solution Approach 1:
The autonomous navigation function is segmented into discrete components: code recognition means for position detection, control entity for decision-making, and drive means for execution. This segmentation allows each component to be optimized independently while working together to achieve high productivity without overwhelming complexity.
Solution Approach 2:
The patent replaces complex mechanical navigation systems with optical code recognition and wireless communication. Instead of mechanical encoders or external guidance infrastructure, the system uses optical codes and electromagnetic communication, simplifying the overall device complexity while maintaining high efficiency.
3Measurement precision
If code recognition means are integrated into carriers, then position accuracy is improved, but external navigation infrastructure is eliminated
Solution Approach 1:
The patent extracts the navigation function from external infrastructure and embeds it directly into the sample carrier. The code recognition means, control entity, and wireless communication means are integrated into the carrier itself, eliminating the need for external navigation systems while achieving precise position recognition through field codes.
