Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single communication scheme (e.g., Bluetooth or Wi-Fi) is used to control multiple robots, then the system structure is simple, but communication failures occur due to spatial obstacles
Solution Approach 1:
The patent applies dynamics by making the communication scheme adaptable and changeable based on real-time conditions. The control server dynamically selects between direct communication and relay communication modes, and relay robots can be reassigned based on their current locations and communication status, transforming a static single-scheme system into a dynamic multi-mode system that responds to environmental changes
Solution Approach 2:
The patent changes communication parameters (communication mode, relay robot selection, signal routing) based on detected spatial conditions. When obstacles are detected or communication quality degrades, the system changes parameters by switching from direct to relay communication, selecting different relay robots based on distance metrics, and adjusting communication paths to maintain reliable connections
2Reliability
If relay robots are introduced to improve communication coverage, then communication reliability improves, but the control system becomes more complex
Solution Approach 1:
The patent introduces relay robots as intermediary elements between the control server and other robots. These relay robots act as mediators that forward communication signals, enabling indirect communication paths when direct paths are blocked. The relay robots are selected based on their spatial positions and communication capabilities, creating a hierarchical communication structure that improves coverage while managing complexity through intelligent selection
Solution Approach 2:
The system implements feedback mechanisms where the control server continuously monitors communication status, robot locations, and connection quality. Based on this feedback, the server dynamically adjusts communication schemes, selects appropriate relay robots, and reassigns roles to maintain optimal communication reliability while adapting to changing environmental conditions
3Reliability
If relay robots are dynamically selected and relocated, then communication coverage is optimized, but the time required to establish connections increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing communication pathways and pre-selecting relay robots based on predicted spatial configurations. The system proactively adjusts communication schemes before communication failures occur, and relay robots are positioned in advance in areas likely to require relaying, reducing the time needed to establish connections when conditions change
