Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional programming methods with scripting languages are used, then automation capability is achieved, but programming complexity and skill requirements increase
Solution Approach 1:
The patent creates a virtual copy of the laboratory automation device and its operational environment. Users interact with this virtual model through VR/AR interfaces, performing pipetting operations in a simulated setting. The system then translates these virtual actions into corresponding control programs for the physical device, eliminating the need for users to write complex scripts while maintaining full automation capability.
Solution Approach 2:
The virtual reality environment serves as an intermediary layer between the user and the physical automation device. Instead of directly programming the device using complex scripting languages, users program through natural interactions in the VR environment, which are then automatically translated into device control commands. This intermediary simplifies the programming interface while preserving automation functionality.
2Ease of operation
If manual teaching mode is used to program robot arm positions, then ease of operation improves, but time consumption increases
Solution Approach 1:
The system creates a virtual replica of the entire laboratory setup including robot arm positions, pipette locations, and sample containers. Users can quickly program by performing operations in this virtual environment, which automatically captures the teaching points and generates control programs. This virtual copying approach is faster than manual physical teaching while maintaining ease of operation through intuitive VR/AR interfaces.
Solution Approach 2:
The system pre-configures the virtual environment with accurate digital twins of the physical device components and their positions. This preliminary setup allows users to immediately begin programming without time-consuming calibration or position setup, as everything is already prepared in the virtual space. The pre-established virtual model enables rapid program development while maintaining operational simplicity.
3Ease of operation
If graphical interface tools are used for programming, then user-friendliness improves, but handling complex procedures becomes difficult
Solution Approach 1:
The patent transitions from traditional 2D graphical interfaces to immersive 3D virtual reality and augmented reality environments. This dimensional enhancement allows users to interact with the automation device in a spatially intuitive manner, naturally handling complex multi-step procedures through realistic hand-eye coordination and spatial reasoning. The 3D environment maintains user-friendliness while significantly improving the ability to program complex workflows.
Solution Approach 2:
The virtual reality environment creates a photorealistic copy of the physical laboratory automation setup, allowing users to program complex procedures by performing natural pipetting actions in the virtual space. This virtual copying preserves all the complexity of real-world operations while providing an intuitive interface, enabling users to handle complex procedures as easily as they would perform them physically, without the limitations of flattened 2D graphical interfaces.
