Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning robot is designed to clean only the bottom of the pool, then the structure is simple, but the application scope is limited
Solution Approach 1:
The cleaning robot employs a dynamic position adjustment mechanism that enables it to transition between different operational positions (above water surface, below water surface, and on the pool bottom). This dynamic capability allows a single robot design to adapt to multiple cleaning scenarios and pool types, expanding application scope without requiring multiple specialized robot designs.
Solution Approach 2:
The cleaning robot is designed with multi-functional capabilities to perform cleaning operations in various positions and environments. The same robot can clean pool surfaces, walls, and bottom areas, and can operate in different water conditions, making it a universal cleaning solution that replaces the need for multiple specialized cleaning devices.
2Productivity
If the cleaning robot cannot adjust depth, then the device complexity is low, but the cleaning efficiency is reduced
Solution Approach 1:
The cleaning robot incorporates a dynamic depth adjustment mechanism that enables it to change its vertical position flexibly. This allows the robot to optimize its cleaning efficiency by positioning itself at different depths according to the specific cleaning task and pool characteristics, rather than being fixed at a single depth.
Solution Approach 2:
The cleaning robot utilizes buoyancy force adjustment as a key parameter change mechanism to control its vertical position. By adjusting the buoyancy force, the robot can efficiently transition between different depths and positions, enabling adaptable cleaning operations without requiring complex mechanical positioning systems.
3Area of stationary object
If the cleaning robot uses fixed position, then the device complexity is low, but the cleaning coverage is limited
Solution Approach 1:
The cleaning robot employs dynamic position adjustment capabilities that allow it to move between above-water and below-water positions, as well as adjust its depth. This dynamic positioning enables the robot to access and clean different areas of the pool that would be inaccessible to fixed-position robots, significantly expanding cleaning coverage.
Solution Approach 2:
The cleaning robot adds vertical dimensionality to its movement capabilities by transitioning between different vertical positions (above water surface, below water surface, and on the bottom). This three-dimensional movement capability allows the robot to clean areas that would be inaccessible to two-dimensional robots, effectively increasing the cleaning coverage area.
