Single-Motor Lifting Device for Dual-Function Cleaning Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning apparatuses require two drivers to rotate and lift cleaning components, increasing volume and manufacturing costs, making them less suitable for small spaces and more expensive.
Innovation Solution
A lifting device with a drive motor, rotating shaft, transmission assembly, and traction member, where the rotating shaft moves in opposite directions to perform both rotation and lifting functions, reducing the need for separate drivers by using a single motor to drive the cleaning component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two drivers are installed to drive rotation and lifting separately, then the cleaning component can perform both rotation and lifting functions, but the volume of the cleaning apparatus increases
Solution Approach 1:
The patent combines the rotation drive and lifting drive functions into a single driver. The driver includes a motor that can rotate in two directions: one direction drives the cleaning component to rotate for cleaning, while the opposite direction drives the cleaning component to lift. This merging of two separate drive systems into one reduces the overall volume of the cleaning apparatus while maintaining both rotation and lifting capabilities.
Solution Approach 2:
The single driver is designed to perform multiple functions by rotating in opposite directions. When rotating in the first direction, it drives the cleaning component to rotate for cleaning operations. When rotating in the second opposite direction, it drives the cleaning component to lift. This multi-functionality allows one component to replace what would traditionally require two separate drivers, thereby reducing apparatus volume.
2Adaptability or versatility
If two drivers are installed to drive rotation and lifting separately, then the cleaning component can perform both rotation and lifting functions, but the manufacturing cost increases
Solution Approach 1:
The patent merges two separate drivers into a single driver unit, which directly reduces the number of components that need to be manufactured and assembled. This consolidation reduces manufacturing costs by eliminating redundant parts and simplifying the production process while maintaining the ability to perform both rotation and lifting functions.
Solution Approach 2:
The single driver is designed with multi-functionality to perform both rotation driving and lifting driving through bidirectional rotation. This universal design reduces the total component count, thereby lowering manufacturing costs while preserving full cleaning functionality.
3Volume of moving object
If a single motor is used to drive both rotation and lifting, then the volume and cost are reduced, but the driver must rotate in opposite directions to perform different functions
Solution Approach 1:
The driver employs dynamic control where the single motor rotates in different directions depending on the required function. The control system dynamically switches the rotation direction: one direction for cleaning rotation, the opposite direction for lifting. This dynamic approach allows a single motor to handle multiple functions without requiring complex mechanical mechanisms, thereby reducing volume while managing control complexity through electronic control.

Function Achieved in This Case
This design allows for efficient rotation and lifting of cleaning components with a single motor, reducing the volume and cost of the cleaning apparatus, enabling it to navigate small spaces effectively while maintaining cleaning functionality.
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 moves in a direction that approaches the mounting portion
