Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the robot cleaner uses fixed mop surfaces on rotating members, then the structure is simple, but the frictional force between mop and floor is insufficient for effective mopping and driving
Solution Approach 1:
The patent applies the dynamics principle by making the mop surface inclination angle adjustable rather than fixed. The mop surface can dynamically change its angle relative to the rotating member based on the floor curvature, allowing the mop to maintain optimal frictional contact with the floor while adapting to different cleaning scenarios.
Solution Approach 2:
The patent changes the geometric parameter of the mop surface by introducing an adjustable inclination angle. This parameter change allows the mop surface to optimize its contact angle with the floor, thereby increasing frictional force for both mopping and driving functions without fundamentally altering the overall structure.
2Adaptability or versatility
If the robot cleaner uses fixed mop surfaces, then the structure is stable, but it cannot effectively mop curved floor surfaces or recessed portions
Solution Approach 1:
The patent makes the mop surface dynamically adjustable in its inclination angle, enabling it to adapt to curved floor surfaces and recessed portions. This dynamic adjustment allows the mop to maintain effective contact with various floor geometries while keeping the base structure relatively simple.
Solution Approach 2:
The patent segments the mop assembly into a rotating member and an independently adjustable mop surface. This segmentation allows the mop surface to be independently positioned at different inclination angles relative to the rotating member, providing adaptability to different floor conditions without complicating the entire cleaner structure.
3Reliability
If the robot cleaner mops curved floor surfaces with fixed mop surfaces, then the structure remains simple, but shock-absorbing capability is insufficient leading to breakdowns
Solution Approach 1:
The dynamic adjustability of the mop surface inclination angle provides inherent shock-absorbing capability. When encountering curved surfaces or recessed portions, the mop surface can adjust its angle to maintain contact, thereby absorbing shocks that would otherwise transmit to the cleaner's structure and cause breakdowns.
4Stability of the object's composition
If one mop surface receives shocks on curved floors, then the local mopping is affected, but the shocks propagate to the other mop surface creating gaps
Solution Approach 1:
The patent segments the mop system into independently adjustable mop surfaces, allowing each surface to independently adjust its inclination angle in response to local floor conditions. This independence prevents shock propagation between mop surfaces and maintains stable contact of both surfaces with the floor, ensuring thorough mopping.
