Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collectors for power tools lack efficient and versatile designs that allow for easy attachment to various rotary hammers and fail to effectively manage dust and debris during drilling operations, leading to poor workplace cleanliness and potential health hazards.
Innovation Solution
A power tool assembly comprising a hand-held power tool and a dust collector with a telescoping suction pipe, an electric motor, a suction fan, and a dust container, along with interchangeable battery packs and a filter system, which includes a primary filter and a secondary impactor to prevent particle bypass, ensuring effective dust collection and user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a dust collector is attached to a rotary hammer to collect dust and debris, then workplace cleanliness is improved, but the device complexity increases due to the need for removable dust containers and filter systems
Solution Approach 1:
The dust collector is divided into separable components including a removable dust container and filter system, allowing the collection function to be added to the rotary hammer without permanently integrating a complex sealed system. The dust container can be detached for disposal and replacement
Solution Approach 2:
The dust container is designed to be removable and replaceable, allowing accumulated dust to be discarded and fresh containers to be installed. This simplifies the overall system by enabling easy maintenance without requiring complex sealing or cleaning mechanisms
2Object-affected harmful factors
If a telescoping suction pipe is used to position the suction inlet proximate to the drill bit, then dust collection effectiveness is improved, but the device complexity increases
Solution Approach 1:
The suction pipe is made telescopic, allowing it to extend and retract to different lengths. This dynamic adjustment enables the suction inlet to be positioned optimally close to the drill bit during operation, improving dust collection effectiveness while maintaining a compact storage profile
3Object-affected harmful factors
If multiple filters are positioned in the dust collector to prevent particle bypass, then filtration effectiveness is improved, but the ease of operation decreases due to maintenance requirements
Solution Approach 1:
The filter system is divided into multiple separate filter elements positioned at different locations in the dust container. This segmentation allows each filter to be independently accessed and serviced, and the modular design enables easy replacement of individual filters without disassembling the entire dust collector
Solution Approach 2:
The filters are designed to be easily removable and replaceable components. When filters become clogged or damaged, they can be quickly discarded and replaced with new filters, simplifying maintenance operations compared to integrated or permanently sealed filter systems
4Adaptability or versatility
If interchangeable battery packs are used to separately power the power tool and dust collector, then adaptability is improved, but the device complexity increases
Solution Approach 1:
Both the rotary hammer and dust collector are designed with compatible battery pack interfaces, allowing a single battery pack type to power both devices. This universal power interface enables the battery to serve multiple functions across different tools, reducing the need for multiple specialized power sources while maintaining adaptability

AI summary
A power tool assembly includes a hand-held power tool and a dust collector. The dust collector includes a housing removably coupled to the power tool, a telescoping suction pipe coupled to the housing, an electric motor positioned in the housing, a suction fan driven by the electric motor and operable to generate a vacuum in the suction pipe, and a dust container coupled to the housing. The dust container is positioned upstream of the suction fan. The power tool assembly further includes first and second power tool battery packs each of which is interchangeably coupled with the power tool and the dust collector for separately powering the power tool and the dust collector, respectively.
