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 frequently due to spatial obstacles
Solution Approach 1:
The patent implements dynamic communication scheme selection where the control server determines the optimal communication method (direct or relay) based on real-time robot positions and connection status. This dynamic adaptation allows the system to switch between communication modes to maintain reliable connections despite spatial obstacles, resolving the contradiction between system simplicity and communication stability.
Solution Approach 2:
The patent introduces a relay robot as an intermediary device to forward communication signals between the control server and target robots when direct communication is blocked by obstacles. This mediator approach enables stable communication in complex spatial environments without requiring complete system redesign, thus improving reliability while maintaining reasonable system complexity.
2Reliability
If relay robots are dynamically determined and positioned, then communication connection stability is improved, but the control system complexity increases
Solution Approach 1:
The control server continuously monitors robot positions, communication connection status, and signal strength, using this feedback information to dynamically determine optimal relay robots and adjust communication schemes. This feedback mechanism enables the system to automatically adapt to changing spatial conditions, maintaining stable communication without requiring complex manual configuration or predetermined relay positions.
Solution Approach 2:
The system enables robots to autonomously report their positions and communication status to the control server, which then automatically determines the optimal communication scheme and relay assignments. This self-service approach reduces the need for complex external control mechanisms while maintaining high communication reliability through automated decision-making.
