Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If different manufacturers use different infrared guide signals and charging station molds, then each manufacturer can optimize their specific robot design, but the development difficulty of the station returning function increases and universality is reduced
Solution Approach 1:
The patent implements a universal infrared receiving head that can process multiple types of infrared guide signals from different manufacturers. The receiving head is designed with multiple receiving elements arranged in specific patterns, enabling it to detect and process various signal types (single signal, dual signals, triple signals) without requiring manufacturer-specific hardware modifications, thus achieving multi-functionality and universality
2Adaptability or versatility
If a universal infrared receiving head with multiple receiving elements is used to process different guide signals, then adaptability to different manufacturers is improved, but the device complexity and cost increase
Solution Approach 1:
The infrared receiving head is segmented into multiple independent receiving elements (first, second, third receiving elements) arranged in specific spatial patterns. Each element can independently detect infrared signals, and the control unit processes signals from different elements to determine robot position and orientation relative to the charging station, enabling universal compatibility through modular segmentation
Solution Approach 2:
The patent merges multiple receiving elements into a single integrated receiving head assembly, combining their detection capabilities to process various infrared signal patterns. The control unit integrates signals from multiple elements to determine robot state and navigate to the charging station, achieving universal adaptability through functional merging
3Productivity
If the robot uses complex navigation path planning with pre-marked target points, then the charging station search efficiency is improved, but the control system complexity increases
Solution Approach 1:
The patent implements pre-marked navigation target points in the detection map before the robot begins its charging station search. These predetermined target points serve as waystations that guide the robot's navigation path, allowing the robot to efficiently locate the charging station area without complex real-time calculations, thus improving search efficiency with minimal control system complexity

AI summary
The present disclosure discloses a universal method for controlling recharge of robot, chip and robot, the method includes: S1, whether the robot has detected the navigation target point or not is determined, if yes, the robot is controlled to move along a planned navigation path, otherwise, the process proceeds to S3; in the moving process, when the charging station signal is received or all the pre-marked navigation target points are traversed, the process proceeds to S2; S2, whether the robot has received the charging station signal or not is determined, if yes, charging on the station is carried out, otherwise, the charging station signal is searched, and when the robot does not receive the charging station signal, the process returns to S1; S3: the robot is controlled to search for the charging station signal until searching the charging station signal, returning to S2, otherwise, walking along the boundary is continued.
