Telescopic Support Arm Cleaning Device for Above-Floor Surface Reach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices, such as floor cleaning robots, are ineffective in cleaning objects or surfaces above the floor level, leading to unsightly accumulation of dust and potential health risks from allergens like dust mite droppings or pollen.
Innovation Solution
A cleaning device with a support arm comprising a telescopic vertical and horizontal section, equipped with a drive mechanism, allows the device to extend above the floor, incorporating a suction unit or duster with electrostatic charging, and a sensor for 3D scanning to navigate and avoid obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a floor cleaning robot is used, then the floor surface can be cleaned effectively, but objects or surfaces above the floor level cannot be cleaned
Solution Approach 1:
The patent extends the cleaning device from two-dimensional floor cleaning to three-dimensional cleaning by adding a vertical support arm that elevates the cleaning head above floor level, enabling cleaning of surfaces at different heights including furniture tops and wall surfaces
Solution Approach 2:
The cleaning device is divided into functionally independent segments: a base section for floor movement, a telescopic support arm for height adjustment, and a cleaning head for surface cleaning. This modular structure allows each component to perform its specific function while maintaining overall system versatility
2Adaptability or versatility
If a fixed-height cleaning device is used, then the device structure is simple, but it cannot reach surfaces at different heights or extend horizontally to distant surfaces
Solution Approach 1:
The support arm incorporates telescopic mechanisms with drive mechanisms that allow dynamic adjustment of both vertical height and horizontal extension distance. This enables the cleaning head to reach various surfaces at different positions and heights adaptively
Solution Approach 2:
The telescopic support arm uses nested tubular structures where smaller diameter tubes are inserted into larger ones, allowing compact storage when retracted and extended configuration when cleaning distant or elevated surfaces, maximizing reach while minimizing space requirements
3Ease of operation
If a telescopic support arm with multi-stage elements is used, then the minimum and maximum height can be optimized, but the device complexity increases
Solution Approach 1:
The patent replaces complex manual telescopic mechanisms with drive mechanisms that automatically control the extension and retraction of telescopic elements. This substitution simplifies operation while maintaining the multi-stage telescopic structure for optimized height range
Solution Approach 2:
The drive mechanisms are integrated into the telescopic structure itself, with each telescopic element having its own drive mechanism for independent control. This self-contained design allows automated height adjustment without requiring external complex control systems
