Working trolley with built-in dust suction system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional working trolleys with dust suction systems are not fully integrated, requiring disassembly of the vacuum cleaner and 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 the system is integrated directly into the trolley body.
Engineering Contradictions & Design Principles
Engineering 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 moved, but the dust collection bucket cannot be replaced independently and requires disassembly of the vacuum cleaner
Solution Approach 1:
The dust suction system is segmented into three main components: the working trolley, the vacuum cleaner body, and the dust collection bucket. The dust collection bucket is designed as an independent removable component that can be separated from the vacuum cleaner body without disassembling other parts. This segmentation allows the bucket to be replaced independently, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The dust collection bucket is extracted as a separate functional component from the vacuum cleaner system. It is positioned in a dedicated space on the working trolley and connected through a through-hole structure, allowing it to be removed independently while the vacuum cleaner body remains integrated with the trolley. This extraction enables independent replacement without affecting other components.
2Adaptability or versatility
If the vacuum cleaner housing is placed on the working trolley, then the system is mobile, but the housing cannot provide protection for internal devices and increases cost
Solution Approach 1:
The working trolley and dust suction system are merged into a single integrated structure. The vacuum cleaner body is mounted on the trolley frame, and the dust collection bucket is positioned in a dedicated space within the trolley. This merging eliminates the need for a separate protective housing, as the trolley frame itself provides protection while enabling mobility, thus reducing manufacturing costs and improving structural efficiency.
3Device complexity
If the dust suction system is fully integrated with the working trolley, then the structure is simplified, but the dust collection bucket replacement becomes more complex
Solution Approach 1:
The dust collection bucket is nested within the vacuum cleaner body and positioned in a dedicated space on the working trolley. The through-hole structure allows the bucket to be accessed and removed independently while maintaining the integrated appearance of the system. This nesting approach simplifies the overall structure while preserving easy replacement capability.

AI summary
A working trolley with built-in dust suction system includes a dust suction system and a trolley. Through directly assembling the dust suction system with the trolley, useless structures in the dust suction system is eliminated, so that the dust suction system can be assembled with the trolley with a more simplified structure. Through directly assembling the dust suction system 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 of the dust suction system 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, thereby facilitating operation for the operator.
