Solution Overview

Problem

Conventional working trolleys with dust suction systems are not fully integrated, requiring disassembly of the vacuum cleaner and trolley structures to replace the dust collection bucket, which is inconvenient and increases costs.

Innovation Solution

A working trolley with a built-in dust suction system featuring a cyclonic dust separation device, exhaust motor, air pipe, and dust storage bucket, where the dust storage bucket can be independently removed without disassembling other components, and a HEPA filter for high-efficiency particulate air filtration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the vacuum cleaner is placed on the working trolley or wheels are installed on the bottom of the vacuum cleaner, then the dust suction system can be made mobile, but the dust collection bucket cannot be replaced independently and requires disassembly of the vacuum cleaner structure

Engineering Contradiction:
ImproveConvenience of replacing dust collection bucketVSAvoidStructure integration of dust suction system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The dust suction system is divided into independent functional modules: the dust collection bucket is separated from the cyclone separator and motor assembly. The bucket can be removed independently through a dedicated opening in the trolley body without disassembling other components, while the motor and cyclone remain integrated with the trolley frame. This segmentation enables easy maintenance and bucket replacement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dust collection bucket is nested within the trolley body structure, with the cyclone separator positioned above it and the motor assembly integrated into the trolley frame. The bucket can be accessed through an opening in the trolley body, allowing it to be removed and reinstalled without affecting the outer trolley structure or other components.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Device complexity

If the vacuum cleaner housing is placed on the working trolley, then the dust suction system can be integrated with the trolley, but the housing of the vacuum cleaner cannot provide protection for internal devices and increases the cost of the working trolley

Engineering Contradiction:
ImproveIntegration of dust suction system with trolleyVSAvoidCost and structural efficiency
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The dust suction system components (motor, cyclone separator) are directly integrated with the trolley body structure. The trolley frame serves as the structural housing that protects internal devices, eliminating the need for a separate vacuum cleaner housing. The motor assembly and cyclone separator are mounted directly to the trolley frame, creating a unified integrated structure that reduces component count and manufacturing cost.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If the dust suction system is fully integrated with the working trolley, then the structure is simplified and the dust collection bucket can be replaced independently, but the integration requires precise structural design of the trolley body

Engineering Contradiction:
ImproveStructure simplification of dust suction systemVSAvoidStructural design precision of trolley body
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The trolley body is designed with segmented functional zones: a working platform area, a dust collection area with removable bucket, and a motor/cyclone assembly area. The bucket opening is positioned to provide direct access to the dust collection bucket without requiring disassembly of the trolley frame or other components. This segmentation allows for precise but modular structural design that balances integration with manufacturability.

Inventive Principle:
Principle #1Segmentation

AI summary

A working trolley (100) with built-in dust suction system (10) includes a dust suction system (10) and a trolley. Through directly assembling the dust suction system (10) with the trolley, useless structures in the dust suction system (10) is eliminated, so that the dust suction system (10) can be assembled with the trolley with a more simplified structure. Through directly assembling the dust suction system (10) with the trolley, the trolley breaks the old and stereotyped way of using, and the trolley is no longer just a carrying tool of a vacuum cleaner, thereby greatly increasing the effectiveness of usage of the trolley. On the other hand, the present invention enables a dust storage bucket (14) of the dust suction system (10) to have a feature of being independently dismountable, so that an operator does not need to dismount other components when replacing the dust storage bucket (14), thereby facilitating operation for the operator.
