Solution Overview

Problem

Existing mobile suction devices are cumbersome and inefficient, particularly when handling bulky suction hoses and dirt collection, as they often require moving the entire device to disposal sites and lack convenient storage and handling solutions.

Innovation Solution

A mobile suction device with a detachable container attachment that provides additional storage for the suction hose, electrical connections, and dust/dirt collection, featuring through-openings for easy connection to the suction inlet and a carrying handle for improved portability, allowing the suction device to be broken down for easier transport and disposal of collected dirt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the suction device is designed as a single integrated unit for dirt collection, then the suction capacity is sufficient, but the device becomes cumbersome and difficult to transport to disposal sites

Engineering Contradiction:
Improvedirt collection capacityVSAvoidtransportability
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The suction device is divided into two main segments: a stationary suction device housing containing the suction unit, and a detachable container attachment for dirt collection. This segmentation allows the dirt collection container to be separated from the suction device and transported independently to disposal sites, solving the problem of moving bulky collected dirt while maintaining sufficient dirt collection capacity during operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container attachment designed according to the invention can be completely detached from the suction device housing. This extraction principle allows the dirt collection container to be removed and transported separately, eliminating the need to move the entire suction device to disposal sites and significantly improving transportability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the suction hose is stored externally on the suction device, then accessibility is improved, but the device becomes bulkier and less portable

Engineering Contradiction:
Improvehose accessibilityVSAvoiddevice footprint
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The container attachment features a receiving cavity designed to nest and store the suction hose when not in use. This nesting principle allows the hose to be compactly stored within the container attachment's internal space, preventing it from protruding excessively and reducing the overall device footprint while maintaining accessibility during operation.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If the suction device housing includes all functional components, then the device is self-sufficient, but it lacks adaptability for additional functions

Engineering Contradiction:
Improvefunctional expandabilityVSAvoidbase device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container attachment is designed as a universal platform that can perform multiple functions: storing the suction hose, providing additional dirt collection capacity, housing electrical connection cables, and serving as a mounting base for operating elements or display elements. This multi-functionality principle allows the base suction device to remain relatively simple while gaining extensive adaptability through the versatile container attachment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Ease of operation

If the suction device is designed for compact storage, then portability is improved, but the suction capacity and dirt collection volume are reduced

Engineering Contradiction:
ImproveportabilityVSAvoiddirt collection volume
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

By segmenting the dirt collection function into a separate detachable container attachment, the system allows the suction device housing to maintain a compact size for portability, while the container attachment provides additional dirt collection volume. The container attachment can be attached when large capacity is needed and detached when portability is the priority, resolving the contradiction between compact storage and dirt collection volume.

Inventive Principle:
Principle #1Segmentation
