Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If exploration robots use extensive advanced inspection devices to obtain comprehensive site information, then the quality and completeness of robot site information is improved, but the amount of information becomes excessive, making it difficult for control personnel to obtain effective information in a short time
Solution Approach 1:
The patent creates a digital twin (virtual replica) of the exploration robot and its environment. This virtual model receives and processes the comprehensive site information from inspection devices, allowing control personnel to interact with the simplified virtual representation rather than raw data streams. The digital twin copies the robot's sensory inputs, processing state, and environmental data into a manageable virtual format that reduces information overload while preserving essential information quality.
Solution Approach 2:
The digital twin acts as an intermediary between the exploration robot's extensive inspection devices and the control personnel. Instead of control personnel directly receiving and processing all raw data from multiple inspection devices, the digital twin intermediate layer synthesizes, filters, and presents relevant information in a condensed format, thereby reducing the time required for control personnel to obtain effective information while maintaining information completeness.
2Loss of information
If exploration robots transmit large amount of information to control personnel, then the completeness of control information is improved, but the control efficiency and precision deteriorate due to information overload
Solution Approach 1:
The digital twin creates a virtual copy of the robot's operational state and environmental context. Control personnel interact with this virtual model to make decisions, which are then transmitted back to the physical robot. This copying mechanism allows complete control information to be available in the virtual model while enabling control personnel to process and make decisions more efficiently than if they were directly managing the full stream of raw data from the robot.
Solution Approach 2:
The control system is segmented into two distinct layers: the digital twin layer for information processing and decision-making, and the physical robot layer for execution. This segmentation allows control personnel to work with the simplified virtual model for efficient decision-making while the digital twin handles the complexity of comprehensive information management, thereby improving control efficiency and precision without sacrificing information completeness.
3Loss of information
If exploration robots use advanced inspection devices and computer information technology, then the comprehensiveness of robot site information is improved, but the complexity of the control system increases
Solution Approach 1:
The patent introduces a digital twin as a virtual copy of the exploration robot and its environment. This digital model consolidates and manages the comprehensive site information from multiple inspection devices, presenting it in a unified virtual representation. By offloading the complexity of integrating and managing data from numerous sensors to the digital twin, the physical control system's complexity is reduced while maintaining comprehensive information availability.
Solution Approach 2:
The digital twin serves as an intermediary layer between the complex network of inspection devices and the control personnel. It handles the complexity of data integration, synchronization, and presentation from multiple sensor sources, thereby reducing the apparent system complexity for control personnel while preserving the comprehensiveness of the collected information.
