Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face issues with increased size and complexity due to central motor placement, leading to reduced maneuverability and inefficient water supply for mop cleaning, as well as inadequate air suction paths, resulting in incomplete cleaning and water distribution problems.
Innovation Solution
A nozzle design with laterally spaced rotation cleaning units, a water tank, and a streamlined air flow path that distributes driving motor weight evenly, allowing for independent motor operation and reduced overall size, facilitating directional change and efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a central rotation motor is used to drive multiple rotating bodies, then device complexity is reduced, but reliability decreases and the suction path becomes longer and more complicated
Solution Approach 1:
The patent divides the single central motor system into multiple independent motor units, with each motor driving its own rotating body independently. This segmentation eliminates the single point of failure and allows each motor to operate autonomously, resolving the contradiction between simplified structure and system reliability.
2Device complexity
If a central rotation motor is positioned at the center of the suction port main body, then device complexity is reduced, but the suction path length increases and maneuverability decreases
Solution Approach 1:
The patent segments the central motor into multiple distributed motor units positioned at different locations within the suction port main body. This allows the suction paths to be shortened and optimized independently for each cleaning head, improving airflow efficiency and maneuverability while maintaining structural simplicity through modular design.
3Device complexity
If the suction port main body height is increased to accommodate central motor placement, then device complexity is reduced, but the cleanable area decreases and user convenience is reduced
Solution Approach 1:
The patent distributes multiple compact motor units throughout the suction port main body instead of concentrating one large motor centrally. This segmentation allows for a more compact overall design with reduced height and volume, enabling the cleaner to access narrow spaces under furniture while maintaining simple modular structures through distributed independent units.
4Adaptability or versatility
If water supply structure is added to the nozzle, then cleaning versatility is improved, but device complexity increases
Solution Approach 1:
The patent integrates the water supply system with the existing motor and rotating body structures by combining water reservoirs, pumps, and spray mechanisms into the same modular units that house the motors. This merging approach allows water supply functionality to be added without creating separate complex systems, as the water and air pathways are coordinated within unified structural modules.
