Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-moving robots, such as glass-wiping robots, require complex mechanisms and significant energy to adjust their movement paths around obstacles, leading to reduced cleaning efficiency.
Innovation Solution
A self-moving robot design featuring a control device, a functional processing module, and a moving module connected through a coupling mechanism that allows the moving module to rotate freely within the functional processing module, equipped with a suction device for surface adhesion and a walking mechanism, enabling efficient navigation around obstacles by turning 90 degrees when encountering them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot repeatedly adjusts its moving direction to navigate around obstacles, then the robot can maintain its cleaning path, but the adjusting time and energy consumption increase significantly
Solution Approach 1:
The robot body is divided into two independent modules: a fixed functional processing module and a movable moving module. The moving module can independently rotate 90 degrees relative to the functional processing module, allowing the robot to change direction without complex adjustments of the entire body. This segmentation enables quick directional changes while maintaining cleaning functionality.
Solution Approach 2:
The moving module is designed with dynamic rotational capability through a connection mechanism that allows free rotation. When encountering an obstacle, the moving module can dynamically rotate 90 degrees to bypass the obstacle, then return to the original position to continue cleaning. This dynamic structure eliminates the need for repeated directional adjustments of the entire robot.
2Adaptability or versatility
If the robot uses induction mechanism, control mechanism and moving mechanism to adjust movement path, then the robot can navigate obstacles, but the device complexity and energy consumption increase
Solution Approach 1:
The robot is segmented into a fixed functional processing module containing the induction and control mechanisms, and a movable moving module containing the cleaning mechanism. This segmentation simplifies the overall structure by localizing complex mechanisms to only the functional processing module, while the moving module remains mechanically simple with only rotational capability.
Solution Approach 2:
The moving module autonomously rotates 90 degrees when encountering an obstacle and automatically returns to its original position after bypassing the obstacle. This self-service capability eliminates the need for complex coordinated control of multiple mechanisms, reducing both device complexity and energy consumption.
3Productivity
If the moving module is freely rotatable relative to the functional processing module, then the robot can navigate obstacles efficiently, but the connection mechanism complexity increases
Solution Approach 1:
The rotational connection mechanism is extracted as a separate, dedicated component between the moving module and functional processing module. This isolated connection mechanism only needs to provide rotational freedom without bearing the entire robot's weight or complexity, simplifying its design while enabling efficient obstacle navigation.
