Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning machines with integral lifting and rotating mop units result in a heavy machine, complicating structure, design, production, and manufacturing, and affecting stability due to changes in center of gravity.
Innovation Solution
A liftable and rotatable mop structure with a mop unit comprising a turntable and a rotatable shaft, where the inner and outer shafts are movable axially but limited circumferentially, allowing independent lifting and rotation of the mop, facilitated by a limiting structure and a spring member for resilient support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mop handle is fixed in position, then the structure is simple, but it cannot accommodate users of different heights or cleaning scenarios requiring different angles
Solution Approach 1:
The mop handle incorporates telescopic sections that allow length adjustment, and a rotating joint that enables angle adjustment. These dynamic features allow the handle to adapt to different user heights and cleaning scenarios, directly resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The handle is divided into multiple telescopic sections that can extend and retract independently. This segmentation allows for flexible length adjustment without requiring a completely complex reconfigurable structure, achieving adaptability while controlling complexity through modular design.
2Adaptability or versatility
If the mop head is fixed at a constant distance from the handle, then the structure is simple, but it cannot adapt to different cleaning surfaces and angles
Solution Approach 1:
The mop head assembly includes a rotating joint connected to the handle and a movable linkage mechanism that allows the mop head to pivot and adjust its angle relative to the handle. This dynamic structure enables adaptation to different cleaning surfaces while maintaining reasonable structural complexity through efficient mechanical design.
Solution Approach 2:
The mop head linkage introduces rotational freedom in multiple dimensions, allowing the mop head to orient itself at various angles relative to the handle. This multi-dimensional adjustment capability enables adaptation to different cleaning surfaces without requiring overly complex control mechanisms.
3Ease of repair
If the mop components are tightly fitted together, then structural stability is high, but disassembly and cleaning are difficult
Solution Approach 1:
The mop is designed with segmented components including telescopic sections, a rotating joint, and a movable mop head linkage. These segments are connected through standardized interfaces that allow easy disassembly for cleaning while maintaining structural stability when assembled, resolving the contradiction between ease of repair and structural stability.
Solution Approach 2:
The mop head and other components can be easily detached from the handle through the designed connection mechanisms. This extraction capability allows for simple disassembly and cleaning without compromising the structural integrity of the remaining components, addressing both ease of repair and stability requirements.
