Vacuum Cleaning Robot Connection Housing for Independent Brush Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic vacuum cleaners face challenges in accommodating multiple housings due to limited installation space, leading to dependencies in brush speeds and increased component losses.
Innovation Solution
A robotic vacuum cleaner design featuring a connecting housing part that combines the main and auxiliary cleaning unit housings, allowing independent control of the cleaning roller and auxiliary cleaning element, with a shared drive train using spur and bevel gears, minimizing space requirements and losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate housings are used for main and auxiliary cleaning units, then independent control of cleaning components is achieved, but installation space requirements increase
Solution Approach 1:
The patent combines the housing of the main cleaning unit and the housing of the auxiliary cleaning unit into a single integrated housing structure. This merging allows both cleaning units to be accommodated within one housing volume, reducing the overall space requirement while maintaining independent control capabilities through separate drive trains within the unified housing.
2Device complexity
If a combined drive train with single motor is used, then component count is reduced, but brush speed independence is lost
Solution Approach 1:
The drive train is segmented into two independent drive trains: a first drive train with a first motor for driving the cleaning roller, and a second drive train with a second motor for driving the auxiliary cleaning element. This segmentation enables independent speed control of each brush while keeping the overall device complexity manageable through modular architecture.
3Quantity of substance
If multiple housings are accommodated in limited space, then all cleaning components can be included, but component losses increase
Solution Approach 1:
By merging the housings into a single integrated structure, the patent reduces the number of interfaces and connections between separate housing components. This reduces energy losses at interfaces and improves overall system efficiency while accommodating all necessary cleaning components within the unified housing.
