Solution Overview

Problem

Existing garbage collection systems for sweeping robots require higher power consumption due to the longer vertical path of garbage movement from the bottom to the dust filter bag, necessitating more powerful blowers for effective cleaning.

Innovation Solution

A garbage collection system with a dust collecting box featuring a transition chamber, storage chamber, and power chamber, where the blower is located in the power chamber and communicates with the storage chamber, and a transmission channel connects the air duct to the dust filter element, reducing the vertical path and allowing for smaller wind power usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the dust collecting box body is arranged at the top of the device with the centrifugal blower at the bottom, then the garbage can be automatically cleaned from the storage box to the dust filter bag, but the vertical path of garbage movement becomes long and higher power is required

Engineering Contradiction:
Improveautomatic garbage cleaningVSAvoidpower consumption of centrifugal blower
Core Design Contradiction:
Extent of automationVSUse of energy by moving object

Solution Approach 1:

The patent changes the arrangement dimension from vertical stacking (top-bottom) to horizontal sequencing (side-by-side). The transition chamber, storage chamber, and power chamber are arranged horizontally, allowing garbage to move horizontally from the air duct through the transmission channel to the dust filter element, eliminating the need for long vertical lifting and reducing the power requirements of the blower.

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

2Device complexity

If the dust collecting box body is arranged at the top with vertical garbage movement path, then the structure is compact, but the path length increases and requires higher blower power

Engineering Contradiction:
Improvestructural compactnessVSAvoidvertical path length
Core Design Contradiction:
Device complexityVSLength of stationary object

Solution Approach 1:

The patent transitions from vertical arrangement to horizontal arrangement of chambers, changing the garbage movement path from vertical to horizontal. This maintains structural compactness while significantly reducing the path length that requires overcoming gravity, thereby reducing the blower power requirements.

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

3Productivity

If the air duct path is extended to reach from bottom to top, then garbage can be transported to the dust filter bag, but the transmission path becomes longer and energy consumption increases

Engineering Contradiction:
Improvegarbage emptying efficiencyVSAvoidenergy loss in air duct transmission
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent redesigns the air duct and transmission channel layout to arrange chambers horizontally, creating a shorter transmission path for garbage. This reduces the length of air duct required and minimizes energy loss during garbage transmission while maintaining effective emptying efficiency.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system enables efficient garbage collection with reduced power consumption by shortening the garbage path and using smaller wind power, allowing for effective emptying of the robot's storage box with lower energy requirements.

Implementation Method 1

Air flow is formed among the storage chamber, the transmission channel and the air duct. The garbage stored in the sweeping robot storage box sequentially passes through the air duct and the transmission channel
