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 a fixed portion and a movable portion, where the movable portion can independently rotate relative to the fixed portion. This segmentation allows the robot to change direction by rotating the movable portion rather than adjusting the entire body, significantly reducing the time and energy required for direction changes while maintaining reliable path navigation around obstacles.
2Reliability
If the robot repeatedly adjusts its moving direction to navigate around obstacles, then the robot can maintain its cleaning path, but the energy consumption increases significantly
Solution Approach 1:
The robot body is divided into a fixed portion and a movable portion, where the movable portion can independently rotate relative to the fixed portion. This segmentation allows the robot to change direction by rotating the movable portion rather than adjusting the entire body, significantly reducing the time and energy required for direction changes while maintaining reliable path navigation around obstacles.
3Adaptability or versatility
If the robot uses a complex adjustment mechanism to navigate around obstacles, then the path adjustment capability is improved, but the device complexity increases
Solution Approach 1:
The robot body is divided into a fixed portion and a movable portion connected by a simple rotating joint. The movable portion can independently rotate to change direction, providing flexible path adjustment capability without requiring complex adjustment mechanisms. This simple rotational connection significantly reduces device complexity while maintaining excellent adaptability for navigating around obstacles.
4Productivity
If the robot increases the adjustment speed to improve cleaning efficiency, then the cleaning efficiency is improved, but the energy consumption increases
Solution Approach 1:
The robot body is divided into a fixed portion and a movable portion, where the movable portion can independently rotate relative to the fixed portion. This segmentation allows the robot to change direction by rotating the movable portion rather than adjusting the entire body, significantly reducing the time and energy required for direction changes while maintaining reliable path navigation around obstacles.
Solution Approach 2:
The movable portion is designed to be dynamically rotatable relative to the fixed portion, allowing the robot to quickly adapt its movement direction in response to obstacles. This dynamic rotational capability enables fast path adjustments that improve cleaning efficiency without requiring excessive energy, as only the lighter movable portion needs to be rotated rather than the entire robot body.
