Solution Overview
Problem
Conventional cleaning devices have limited flexibility due to a small adjustable angle between the cleaning head and the main body, making them less user-friendly and less effective for cleaning various surfaces and hard-to-reach areas.
Innovation Solution
A cleaning device with a connection mechanism featuring at least two rotational connection portions with non-parallel rotation axes, allowing the main body to rotate relative to the cleaning assembly in multiple directions, enhancing flexibility and user control, and including a cleaning liquid supply system and dirt recovery system for efficient cleaning and waste management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single rotational connection is used between the main body and cleaning assembly, then the structure is simple, but the adjustable angle range is limited and flexibility is poor
Solution Approach 1:
The connection mechanism is divided into multiple rotational connection portions (first rotational connection portion and second rotational connection portion), each providing independent rotation around different axes. This segmentation allows the cleaning assembly to achieve multi-directional adjustment capabilities while keeping each individual rotational joint relatively simple in structure.
Solution Approach 2:
The patent introduces rotation around non-parallel axes (different dimensional directions), transforming a single-degree-of-freedom connection into a multi-degree-of-freedom connection. This dimensional expansion enables the cleaning assembly to adjust angles in multiple directions, significantly improving adaptability without requiring an excessively complex single-joint mechanism.
2Ease of operation
If the cleaning head angle is fixed, then the structure is stable, but the user-friendliness and flexibility are reduced
Solution Approach 1:
The connection mechanism transitions from a fixed rigid connection to a dynamic adjustable connection with multiple rotational degrees of freedom. The cleaning assembly can be adjusted to different angles and positions during operation, making the device more adaptable to various cleaning scenarios and improving ease of operation.
Solution Approach 2:
The multi rotational connection mechanism enables the cleaning device to handle multiple cleaning scenarios (different surfaces, angles, and hard-to-reach areas) with a single device configuration, enhancing its universality and user-friendliness without requiring multiple specialized tools.
