Mop unit lifting device and cleaning machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning machines with rotatable mop units lift and lower the entire frame, leading to a heavy machine with an unstable center of gravity, complicating design, production, and increasing costs.
Innovation Solution
A mop unit lifting device that allows the mop unit to be directly lifted and lowered separately from the driving mechanism, using mechanisms like rack-and-pinion, screw, or electromagnetic systems, reducing the weight of the lifted portion and optimizing the center of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the frame or housing in which the mop units are mounted is lifted and lowered as a whole, then the mop units can be lifted, but the machine becomes heavy and the center of gravity becomes unstable
Solution Approach 1:
The patent divides the lifting system into separate components: the mop unit can be lifted independently from the driving mechanism. The lifting mechanism is separated from the driving mechanism, allowing selective lifting of only the necessary components (mop unit and lifting mechanism) while leaving the driving mechanism stationary. This segmentation reduces the weight of the lifted portion and stabilizes the center of gravity by excluding the heavy driving mechanism from the lifting operation.
2Device complexity
If the driving mechanism is mounted in the frame or housing for driving the mop units to rotate, then the mop units can be driven to rotate, but the structure becomes complicated and production costs increase
Solution Approach 1:
The patent separates the lifting mechanism from the driving mechanism, creating two independent functional modules. The driving mechanism remains stationary in the housing while the lifting mechanism is dedicated solely to lifting the mop unit. This segmentation simplifies the overall structure by eliminating the need to integrate lifting and driving functions into a single complex assembly, thereby reducing production complexity and manufacturing costs.
Solution Approach 2:
The patent extracts the lifting function from the frame/housing structure and creates a dedicated lifting mechanism that operates independently. This extraction allows the driving mechanism to remain simple and stationary, while the lifting mechanism handles all lifting operations. The separation reduces structural complexity and makes the system easier to manufacture and assemble.
