Solution Overview

Problem

Existing cleaning robots have limited dust box volume and storage space due to the rear placement of the dust box, which is affected by other main components, leading to reduced user experience and increased cleaning frequency.

Innovation Solution

The dust box is positioned in front of the rolling brush assembly, allowing for increased volume and storage space by avoiding interference from other components, with a fan connected through a dust suction pipe and a radar assembly placed behind to maintain structural compactness and balance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If the dust box is arranged on the rear side of the rolling brush assembly, then the structure is simplified, but the dust box volume and storage space are limited due to interference from other main components

Engineering Contradiction:
Improvedust box volumeVSAvoidstructural arrangement
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The patent inverts the conventional arrangement by placing the dust box in front of the rolling brush assembly instead of behind it. This reversal allows the dust box to occupy the front portion of the body where space is otherwise underutilized, thereby increasing dust box volume without interfering with other main components located in the middle and rear portions of the body.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent utilizes the front portion of the body in the advancing direction, which is typically not occupied by main components. By arranging the dust box in this spatial dimension (front area), the design expands the available volume for dust storage without complicating the overall structural arrangement.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If the dust box is arranged on the rear side of the rolling brush assembly, then the layout is conventional, but the storage space is reduced leading to increased cleaning frequency

Engineering Contradiction:
Improvestorage spaceVSAvoidcleaning frequency
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

By inverting the conventional rear placement to front placement, the dust box can accommodate more garbage, increasing storage space. This reduces the frequency with which the dust box needs to be emptied, thereby reducing the time loss associated with frequent cleaning operations.

Inventive Principle:
Principle #13The other way round (Inversion)

3Volume of stationary object

If the rolling brush assembly is positioned between the two traveling assemblies with overlapping projections, then the dust box volume is maximized, but the structural compactness may be affected

Engineering Contradiction:
Improvedust box volumeVSAvoidstructural compactness
Core Design Contradiction:
Volume of stationary objectVSShape

Solution Approach 1:

The patent segments the body into distinct functional zones: the front portion houses the dust box, the middle portion contains the rolling brush assembly between the traveling assemblies, and the rear portion accommodates other main components. This segmentation allows each component to be optimally positioned for its function while maintaining overall structural compactness through organized spatial distribution.

Inventive Principle:
Principle #1Segmentation
