Solution Overview

Problem

Conventional suction cleaners face challenges such as large volume, high weight, and low dust collection capacity, making them inconvenient for cleaning surfaces other than floors and prone to blockages due to limited dust collection capabilities.

Innovation Solution

A rod handheld two-in-one separated-type suction cleaner with an independent dust-air separation and dust storage device, allowing for increased dust collection capacity and preventing blockages by separating the main device, push rod, and ground brush, and featuring a first and second dust collecting device for efficient filtration and dust management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a single dust collecting device is provided in the handheld suction cleaner, then the main device can be kept compact and lightweight, but the dust collection capacity is limited and blockage is more likely to occur

Engineering Contradiction:
Improvedust collection capacityVSAvoidmain device volume and weight
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The dust collecting device is divided into two separate devices: a first dust collecting device and a second dust collecting device. The first dust collecting device is detachably arranged between the ground brush and the main device, while the second dust collecting device is built into the main device. This segmentation allows the system to handle larger dust quantities and prevent blockages by distributing dust collection across two devices, while each individual device can remain relatively compact.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the suction cleaner is designed as a vertical type with integral ground brush and machine head, then it is suitable for large area ground cleaning, but it is very inconvenient for cleaning of wall surfaces, sofas, windows, desktops and electrical appliances

Engineering Contradiction:
Improvecleaning surface adaptabilityVSAvoidoperation convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The suction cleaner is designed with dynamic configurability, allowing the ground brush and push rod to be detachably connected to the main device. Users can assemble the ground brush and push rod with the main device for ground cleaning, or use the main device alone for cleaning walls, sofas, windows, desktops and electrical appliances. This dynamic reconfiguration enables the system to adapt to different cleaning scenarios while maintaining operational simplicity.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the fan is connected to the ground brush through the hose in horizontal suction cleaner, then the ground brush can be moved for cleaning, but the connection distance is long resulting in large energy loss

Engineering Contradiction:
ImprovemobilityVSAvoidenergy loss
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The fan is extracted from the ground brush assembly and placed in a separate main device. The ground brush and push rod can be detachably connected to the main device, allowing the ground brush to be used independently or combined with the main device. This extraction eliminates the need for long hoses connecting the fan to the ground brush, reducing energy loss while maintaining mobility for both ground cleaning and handheld cleaning operations.

Inventive Principle:
Principle #2Taking out (Extraction)
