Single-Motor Lifting Device for Compact Cleaning Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning apparatuses with lifting functions have increased volume due to the need for two drivers, one for rotation and one for lifting, making them less suitable for cleaning in small spaces and increasing manufacturing costs.
Innovation Solution
A lifting device that integrates a drive motor, rotating shaft, transmission assembly, and traction member, allowing the rotating shaft to move up or down through different rotation directions of the drive motor, thereby eliminating the need for a separate lifting driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two drivers are installed to achieve both rotation and lifting functions, then the cleaning apparatus can effectively lift cleaning components to avoid bumps and contamination, but the volume of the cleaning apparatus is increased
Solution Approach 1:
The patent combines the lifting function and rotation function into a single driver through a integrated drive mechanism. The driver includes a motor, a transmission mechanism with a first transmission component (for lifting motion) and a second transmission component (for rotation motion), allowing both functions to be achieved by one motor unit rather than requiring separate drivers for each function.
Solution Approach 2:
The single driver is designed to perform multiple functions: it can drive the cleaning component to rotate for mopping and simultaneously drive the cleaning component to lift when encountering uneven ground or carpets. This multi-functional design eliminates the need for separate dedicated drivers for lifting and rotation operations.
2Reliability
If two drivers are installed to achieve both rotation and lifting functions, then the cleaning apparatus can effectively improve practicality, but the manufacturing cost is increased
Solution Approach 1:
The patent merges the lifting mechanism and rotation mechanism into a single integrated driver assembly. This consolidation reduces the total number of motor units required from two to one, thereby reducing manufacturing costs associated with purchasing, assembling, and maintaining multiple separate drivers while preserving both lifting and rotation functionalities.
3Reliability
If two drivers are installed to achieve both rotation and lifting functions, then the cleaning apparatus can effectively handle uneven ground and carpets, but the cleaning apparatus is not suitable for small space cleaning operations
Solution Approach 1:
The integrated driver design consolidates the lifting and rotation functions into a single compact motor unit, reducing the overall volume of the cleaning apparatus. This compact design makes the device more suitable for cleaning operations in small spaces while maintaining the capability to handle uneven ground and carpets through the coordinated action of the transmission components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces the volume of the cleaning apparatus by integrating lifting and rotating functions into a single motor-driven system, enabling effective cleaning in narrow spaces while lowering manufacturing costs.
Implementation Method 1
the traction member is threaded to the lifting drive portion; when the rotating shaft is rotated in a first rotation direction driven by the drive motor, the lifting drive portion rotates relative to the traction member and the rotating shaft moves in a direction that approaches the surface to be cleaned
