Solution Overview
Problem
Traditional ground cleaning devices fail to effectively dry wet and slippery floors after cleaning, leading to safety hazards and water stains.
Innovation Solution
A ground cleaning device comprising a ground brush assembly, a main body with a fan assembly, and a switching mechanism that controls airflow direction to quickly dry the floor by directing air towards the rear when the floor is wet and towards the front when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional cleaning devices use a scraper, sponge, or cloth to wipe the floor, then water is absorbed and the floor is cleaned, but the floor remains slippery for a long time
Solution Approach 1:
The patent applies pneumatic principles by using a fan assembly to generate airflow that rapidly evaporates residual water on the floor surface. The air outlet channels direct high-velocity air onto the cleaned floor, accelerating the drying process and eliminating the slippery condition that persists with traditional absorption methods.
Solution Approach 2:
The patent utilizes phase transition by directing airflow to promote rapid evaporation of residual water from liquid to vapor state. This phase change approach quickly removes moisture from the floor surface, addressing the safety issue of slippery floors that traditional absorption methods fail to resolve efficiently.
2Productivity
If airflow is directed towards the rear to dry the floor, then drying efficiency is improved, but wind noise increases and user experience deteriorates
Solution Approach 1:
The patent implements dynamic adaptability through a switching mechanism that allows the air outlet channels to change direction based on operational mode. The system can switch between rear-directed airflow for maximum drying efficiency and front-directed airflow for reduced wind noise, providing dynamic optimization of the contradiction between productivity and harmful factors.
Solution Approach 2:
The patent applies parameter changes by modifying the direction parameter of the airflow output. The switching mechanism alters the orientation of air outlet channels between rearward and forward directions, enabling the system to adjust the airflow parameter to match different operational requirements and minimize negative effects.
3Adaptability or versatility
If a switching mechanism is added to control airflow direction, then adaptability is improved, but device complexity increases
Solution Approach 1:
The switching mechanism serves multiple functions: it controls airflow direction for both drying mode (rearward) and transport mode (forward), integrates with the existing fan assembly and air outlet structure, and enables the single device to adapt to different operational scenarios without requiring separate systems for each function.
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 device efficiently dries wet and slippery floors, enhancing safety and reducing water stains, while also reducing wind noise and improving user experience by directing airflow away from the user.
Implementation Method 1
a fan assembly (30), and a switching mechanism (40). The fan assembly (30) may be located on the main body (20) and may comprise an air inlet (31) and an air outlet (32)
Implementation Method 2
When the switching mechanism (40) is in the second state, the switching mechanism (40) may open the rear air outlet channel (24) to connect the main air outlet channel (22) with the rear air outlet channel (24). The rear air outlet channel (24) may be used to direct the airflow to the cleaning surface

AI summary
The present disclosure describes a ground cleaning device that comprises a ground brush, a main body, and a fan. The fan may be located inside the main body and may comprise an air inlet and an air outlet. The main body may comprise a main air outlet channel, a front air outlet channel, and a rear air outlet channel. One end of the main air outlet channel may be connected to a switching device, which has a first state and a second state. Based on the switching device being in the first state, the switching device may close the rear air outlet channel to disconnect the main air outlet channel from the rear air outlet channel. Based on the switching device being in the second state, the switching device may open the rear air outlet channel to connect the main air outlet channel to the rear air outlet channel.
