Guide Rail-Supported Dust Receptacle for Handheld Power Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing collection receptacles for handheld power tools increase the weight and influence on the operation of the tool, potentially affecting the quality of the workpiece being processed, as they need to be manipulated separately and can hinder the operation of the handheld power tool.
Innovation Solution
A collection receptacle with a support means that allows it to be coupled to a handheld power tool, featuring a rigid shell with a flexible portion and a support bracket or wheels for stable positioning on a guide rail or base plate, reducing the influence on the tool's operation and enhancing handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a collection receptacle is coupled to a handheld power tool, then workpiece particles can be collected, but the weight and influence on the operation of the tool increases
Solution Approach 1:
The collection receptacle is designed as a separate, detachable component from the handheld power tool. The support means includes a detachable connection to the base plate, allowing the receptacle to be segmented from the tool during operation. This segmentation reduces the effective weight that the user must manipulate during cutting operations while maintaining particle collection capability when the receptacle is attached.
Solution Approach 2:
The support means utilizes the vertical dimension by extending downward from the base plate to contact the guide rail or workpiece surface. This dimensional extension allows the collection receptacle's weight to be supported in a different spatial dimension (vertically downward to the guide rail) rather than adding to the horizontal manipulation weight of the tool assembly.
2Quantity of substance
If a collection receptacle with large volume is used, then more workpiece particles can be collected, but the handling and operation becomes more difficult
Solution Approach 1:
The support means acts as a counterbalancing mechanism by providing external support from the guide rail or workpiece surface. This support structure counteracts the weight of the large-volume collection receptacle, making it easier to handle and maneuver during operation. The receptacle can have large capacity without proportionally increasing the manipulation difficulty because the support means compensates for the additional weight.
3Device complexity
If the collection receptacle is supported on the handheld power tool, then the structure is simplified, but the weight of the tool increases
Solution Approach 1:
The support function is extracted from the handheld power tool itself and transferred to external elements (guide rail or workpiece surface). The support means includes elements that extend outward from the tool assembly to contact these external surfaces, thereby taking the weight-bearing function out of the tool's internal structure and distributing it to external support points.
