Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines lack an efficient mechanism for effective suction and dirt removal, particularly in areas with varying surface textures and types, leading to incomplete cleaning and user fatigue due to inadequate design for ease of use.
Innovation Solution
The floor cleaning machine incorporates a suction channel system with adjustable mouth walls and a contact element that protrudes into the cleaning roller, creating a negative pressure zone for enhanced suction, combined with a rotating cleaning roller and supplementary air supply for effective dirt pickup, allowing for efficient cleaning of various surfaces without the need for supporting wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional suction channel design is used, then the device complexity is reduced, but the suction efficiency and dirt removal capability are insufficient
Solution Approach 1:
The suction channel is divided into multiple segments including a first suction channel, second suction channel, third suction channel, and fourth suction channel, each with specific functions. This segmentation allows optimized airflow paths and improved suction efficiency while maintaining manageable device complexity through modular design.
Solution Approach 2:
The suction channels are arranged in a nested configuration where channels are positioned within or alongside each other, creating an integrated structure that maximizes suction effectiveness while minimizing the overall space required, thus balancing complexity with performance.
2Reliability
If the mouth walls are spaced apart, then the device complexity is reduced, but the suction effectiveness and negative pressure generation are insufficient
Solution Approach 1:
The first mouth wall and second mouth wall are positioned asymmetrically relative to the cleaning roller, with the first mouth wall having a different configuration than the second. This asymmetric arrangement creates effective negative pressure zones that enhance suction effectiveness while maintaining a relatively simple overall structure.
3Stability of the object's composition
If supporting wheels are added, then the device stability is improved, but the surface damage risk and cleaning quality deteriorate
Solution Approach 1:
The design extracts and removes the supporting wheels from the system entirely. The floor cleaning machine is designed to be supported and stabilized through alternative means such as the cleaning roller itself and the structural design of the support device, eliminating the harmful effect of wheels on floor surfaces while maintaining device stability.
4Productivity
If the cleaning roller rotates faster, then the cleaning productivity is improved, but the user effort and control difficulty increase
Solution Approach 1:
The cleaning roller is designed to rotate through the interaction between the cleaning substrate and the floor surface itself, rather than requiring direct mechanical drive from the user. The relative motion between the roller and floor generates the necessary rotation, making the system self-driven and easy to control while maintaining high cleaning productivity.
