Problem
Existing cleaning machines are limited in functionality and fail to effectively remove sewage from the cleaning area, leading to poor cleaning efficiency and safety risks due to slippery floors.
Innovation Solution
A multifunctional cleaning machine with a housing, water inlet and drainage pipes, and a rotating water spray rod that forms a rotational flow for spray washing and simultaneous sewage removal, equipped with a splash shield and wheel assembly for enhanced functionality and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-function floor cleaning machine is used, then the device complexity is low, but the adaptability is limited and cannot meet diverse user requirements
Solution Approach 1:
The cleaning machine integrates multiple functions including high-pressure water spraying for floor cleaning, sewage suction through the water drainage pipe, and water circulation through the connecting pipe. This multi-functional design allows the device to handle diverse cleaning scenarios while maintaining a relatively compact structure, directly resolving the contradiction between adaptability and device complexity.
2Productivity
If only floor cleaning function is provided, then the device complexity is low, but the productivity is reduced due to inability to remove sewage
Solution Approach 1:
The patent combines floor cleaning and sewage removal functions into a single integrated system. The water inlet pipe delivers cleaning water, the rotating water spray rod distributes it across the floor, and the water drainage pipe simultaneously removes sewage. This merging of functions increases productivity by eliminating the need for separate cleaning and sewage removal operations, while the integrated design keeps the overall device complexity manageable.
3Reliability
If sewage remains on the floor after cleaning, then the device complexity is low, but the reliability deteriorates due to safety risks
Solution Approach 1:
The cleaning machine performs self-service by automatically removing the sewage it generates during the cleaning process. The water drainage pipe is positioned to suction sewage from the cleaning chamber, and the connecting pipe enables water circulation to facilitate sewage removal. This self-service capability ensures the floor remains clean and safe without requiring additional manual intervention or complex external systems, thereby improving reliability while maintaining reasonable device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine efficiently cleans floors while removing sewage, improving safety by preventing slipping hazards and expanding usage scenarios beyond single-floor cleaning.
Implementation Method 1
a first water jet being provided at one side of the water spray rod, and a second water jet being provided on the other side of the water spray rod; the first water inlet, the first water outlet, the first water jet, and the second water jet are communicated with each other
Implementation Method 2
the water spray rod rotates to enable the high pressure water source ejected from the first water jet and the second water jet to form a rotational flow in the cleaning chamber for spray washing the floor
Implementation Method 3
a water drainage pipe connected to the housing, the water drainage pipe having a second water inlet and a second water outlet, the second water inlet being located on the lower side of the housing, the second water inlet being located in the cleaning chamber
