Solution Overview
Problem
Existing ground cleaning machines and mopping devices face challenges such as limited functionality to either dry sweeping or wet mopping, leading to water stains, increased noise, complex structures, high costs, and poor dirt removal efficiency due to the absence of negative pressure.
Innovation Solution
A ground cleaning apparatus with a modular design, featuring a rolling brush assembly, a threaded rod assembly, and a dirt holding tank, which uses a unique mechanism to transmit wastewater and dirt from the rolling brush to a dirt discharging opening, eliminating the need for a vacuum cleaner and reducing noise and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high-speed motor is used to achieve strong suction, then cleaning effectiveness is improved, but noise increases significantly
Solution Approach 1:
The patent extracts and removes the vacuum cleaner mechanism (high-speed motor) from the ground cleaning apparatus. Instead of using negative pressure suction, the invention uses a rolling brush assembly that mechanically scrubs the ground surface, thereby eliminating the noise source while maintaining cleaning effectiveness through direct mechanical action rather than aerodynamic suction.
Solution Approach 2:
The patent replaces the pneumatic system (vacuum motor creating negative pressure) with a direct mechanical system (rolling brush assembly). The cleaning function is achieved through mechanical scrubbing action of the rolling brush against the ground, substituting the high-speed motor's aerodynamic action with a simpler mechanical rolling and scrubbing mechanism that produces minimal noise.
2Productivity
If a vacuum cleaner mechanism is combined with a rolling brush structure, then cleaning effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent merges the cleaning functions into a single integrated rolling brush assembly that performs both the scrubbing action and collects debris. The rolling brush assembly combines the functions of ground contact, mechanical scrubbing, and debris collection in one unified structure, eliminating the need for separate vacuum cleaner mechanisms and reducing overall device complexity.
Solution Approach 2:
The rolling brush assembly serves multiple functions simultaneously: it scrubs the ground surface, collects debris through its structure, and transfers waste to the storage container. This multi-functional design eliminates the need for separate specialized components, thereby reducing device complexity while maintaining comprehensive cleaning effectiveness.
3Productivity
If a scraper is used to remove water stains from the roller brush, then mopping effectiveness is improved, but the scraper and rolling brush are easily damaged
Solution Approach 1:
The patent removes the scraper component from the system entirely. Instead of using a scraper to forcibly remove water stains from the rolling brush, the invention uses the rolling brush's own rotation and structure to naturally shed and collect water and debris. The rolling brush assembly is designed to self-clean through its rotational motion, eliminating the need for a separate scraper that would cause damage to both itself and the rolling brush.
Solution Approach 2:
The rolling brush assembly performs self-cleaning through its own rotational motion. As the rolling brush rotates against the ground, water and debris are naturally lifted and transferred to the waste collection area through the brush's structure and rotation, without requiring an external scraper. This self-service mechanism eliminates component damage while maintaining mopping effectiveness.
4Power
If a high-speed motor is used, then suction power is improved, but energy consumption increases
Solution Approach 1:
The patent replaces the high-speed motor's aerodynamic suction system with a mechanical rolling brush system. The cleaning power is generated through the mechanical rotation and contact of the rolling brush with the ground surface, which requires significantly less energy than high-speed aerodynamic suction. The mechanical rolling action provides sufficient cleaning power without the high energy consumption of vacuum motors.
