Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional navigation methods are used for indoor robot docking, then the system structure is simple, but the navigation precision and docking accuracy are insufficient
Solution Approach 1:
The navigation system is segmented into three functional modules: infrared signal receiving units for directional detection, distance measuring units for range detection, and processing units for control. This segmentation allows each module to specialize in a specific detection task, improving overall docking precision while keeping individual components relatively simple
Solution Approach 2:
Infrared signals are introduced as an intermediary medium between the robot and target device. The infrared transmission unit emits signals that form a radiation region, and the receiving units detect these signals to determine position and orientation. This intermediary enables precise navigation without requiring complex direct sensing mechanisms
2Measurement precision
If multiple sensors are used to improve navigation accuracy, then the measurement precision improves, but the device complexity and cost increase
Solution Approach 1:
The infrared transmission unit serves multiple functions: it emits infrared signals for position detection, creates a radiation region for orientation detection, and enables both receiving units to work simultaneously for redundant measurement. This multi-functionality reduces the need for separate specialized sensors
Solution Approach 2:
The target device itself serves as the signal source through the infrared transmission unit, eliminating the need for external signal generators or markers. The system uses its own components to generate and detect signals, reducing overall system complexity while maintaining high precision
