Solution Overview
Problem
Existing cleaners face challenges in efficiently suctioning foreign matter while maintaining a slim and compact design, rotating mops for effective cleaning, and supplying water to mops without increasing the nozzle's size or complexity, leading to reduced cleaning performance and difficulty in navigating narrow spaces.
Innovation Solution
A nozzle design featuring a suction flow path with laterally spaced rotation cleaning units, each driven by a separate motor, and a water tank integrated into the nozzle housing, with driving unit covers to simplify the structure and reduce volume, allowing for efficient suction, mop rotation, and water supply without elongating the air flow path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rotation motor is used to drive multiple rotating bodies, then device complexity is reduced, but reliability decreases and all rotating bodies cannot operate if the motor fails
Solution Approach 1:
The patent divides the single rotation motor into multiple independent rotation motors, with each motor dedicated to driving a specific rotating body. This segmentation ensures that if one motor fails, other rotating bodies can continue to operate independently, thereby improving reliability while maintaining manageable device complexity through modular design
2Volume of moving object
If the rotation motor is positioned at the center of the suction port main body, then space utilization is improved, but the suction path length increases and structure becomes complicated
Solution Approach 1:
The patent extracts the rotation motor from the central position of the suction port main body and relocates it to the rear end. This extraction eliminates the interference between the centrally positioned motor and the suction path, allowing for a shorter and simpler suction path design while still achieving compact overall dimensions through optimized component arrangement
3Ease of manufacture
If the suction port main body height is increased to accommodate central motor placement, then motor installation is facilitated, but the cleaner cannot easily enter narrow spaces and cleanable area is reduced
Solution Approach 1:
The patent extracts the rotation motor from the central position and relocates it to the rear end of the suction port main body. This relocation eliminates the need to increase the height of the suction port main body, keeping the overall dimensions compact and allowing the cleaner to easily navigate narrow spaces and furniture areas while maintaining ease of motor installation at the rear end
4Weight of moving object
If the suction port main body is moved eccentrically, then weight distribution may change, but the amount of eccentricity increases and it becomes difficult to move back to the original straight path
Solution Approach 1:
The patent employs asymmetric distribution of rotation motors and rotating bodies, with each side independently configured. This asymmetric yet balanced design allows for proper weight distribution while maintaining the suction port main body in a straight, balanced position during operation, preventing excessive eccentricity and ensuring ease of handling and control
