Solution Overview

Problem

Robotic vacuum cleaners have dust-extraction blind areas in their dust boxes, leading to dust accumulation and reduced storage space, making it difficult to collect all dust during cleaning operations.

Innovation Solution

A cleaning robot with a dust box and dust extraction duct design where the dust collection port and extraction port are positioned on opposite sides of the centerline, allowing airflow to pass through the internal space of the dust box, reducing blind areas and improving dust extraction efficiency. The system includes a base station with a dust collection bag and pump for effective dust removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the dust collection port and dust extraction port are positioned on the same side of the dust box, then the structure is simple, but dust extraction blind areas are created leading to dust accumulation

Engineering Contradiction:
Improvestructural simplicityVSAvoiddust extraction completeness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The dust box is segmented into distinct functional zones by positioning the dust collection port and dust extraction port at opposite ends, creating a linear dust flow path that divides the internal space into collection zone and extraction zone, eliminating blind areas where dust could accumulate

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-sided port configuration to a dual-ended configuration along the longitudinal dimension of the dust box, creating a linear airflow path that spans the entire length of the dust box, thereby eliminating extraction blind areas through dimensional extension

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

2Volume of stationary object

If the dust box is completely emptied of dust, then storage space is maximized, but dust extraction blind areas prevent complete dust removal

Engineering Contradiction:
Improvedust box storage spaceVSAvoiddust extraction efficiency
Core Design Contradiction:
Volume of stationary objectVSProductivity

Solution Approach 1:

The dust box internal space is segmented into a collection region near the dust collection port and an extraction region near the dust extraction port, with dust flowing linearly from one end to the other, ensuring complete evacuation of the storage space without leaving blind areas

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The linear arrangement of ports creates a continuous dust extraction path from the dust collection port through the entire dust box volume to the dust extraction port, maintaining continuous airflow that prevents dust accumulation and ensures complete emptying of the storage space

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A cleaning robot includes a housing, a dust box and a dust extraction duct. The housing is enclosed to form a mounting chamber and is provided with a dust outlet. The dust box is arranged in the mounting chamber and configured to collect dust, and the dust box is provided with a dust collection port and a dust extraction port. The dust collection port and the dust extraction port are respectively disposed on two sides of a centerline of the dust box. One end of the dust extraction duct communicates with the dust extraction port, and the other end of the dust extraction duct is connected to the dust outlet of the housing.
