Solution Overview
Problem
Existing surface-cleaning machines face challenges in achieving comprehensive cleaning capabilities with efficient suction and edge cleaning while minimizing false air intake, which often require powerful and heavy fan motors.
Innovation Solution
The surface-cleaning machine features a cleaning head with distinct regions for suction mouths and a central drive mechanism, allowing for optimized suction and edge cleaning without drawing false air, using a two-part cleaning roller and separate suction pipes connected via a manifold pipe, and incorporating a wetting device for enhanced cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single suction mouth is used for the cleaning roller, then the structure is simple, but false air is drawn in and suction performance is reduced
Solution Approach 1:
The suction system is divided into multiple independent suction mouths (first suction mouth at the first face side, second suction mouth at the second face side, and third suction mouth at the central region) that operate simultaneously. Each suction mouth handles a specific zone, preventing false air intake while maintaining comprehensive suction coverage across the entire cleaning roller length.
2Adaptability or versatility
If drive elements are positioned close to the edges for edge cleaning, then edge cleaning capability is improved, but the structure becomes more complex and space is consumed
Solution Approach 1:
The drive mechanism is repositioned from the traditional edge-mounted configuration to the central region of the cleaning head. The central drive transmits power through the cleaning roller via the central suction mouth region, enabling edge cleaning functionality without requiring complex edge-mounted drive elements. This dimensional relocation simplifies the overall structure while maintaining edge cleaning capability.
3Productivity
If a powerful fan motor is used to prevent false air intake, then suction performance is improved, but the motor weight and power consumption increase
Solution Approach 1:
The suction system is segmented into multiple independent suction mouths that create localized suction zones. This segmentation prevents false air intake by design, allowing the use of a less powerful fan motor while maintaining effective suction performance. The multi-zone approach eliminates the need for high-power motors that would be required to prevent false air in a single-zone system.
