Powder Bucket Funnel and Scraper for Precise Small-Opening Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder dispensing devices suffer from powder scattering and inaccurate quantification when dispensing into containers with small openings, leading to loss and reduced precision in experimental processes.
Innovation Solution
A powder bucket with a rotatable stirring rod, funnel, and scraper design that collects scattered powder and ensures precise dispensing by guiding it through a powder leakage port, compatible with containers of various sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If powder is discharged from a conventional powder bucket, then powder can be dispensed into a container, but powder scatters around causing loss and inaccurate quantification
Solution Approach 1:
The patent introduces a funnel as an intermediary component between the powder bucket and the container. The funnel collects scattered powder that would otherwise be lost and guides it into the container, ensuring complete transfer of the intended powder quantity and eliminating both powder loss and quantification errors
Solution Approach 2:
The patent converts the harmful scattering effect into a beneficial collection mechanism. The funnel is positioned to intercept scattered powder particles and redirect them into the container, transforming the previously harmful dispersion into a useful collection and guidance function that improves both powder recovery and dosing accuracy
2Adaptability or versatility
If a conventional powder bucket is used, then powder can be dispensed, but the design does not accommodate containers with small openings effectively
Solution Approach 1:
The patent implements a rotatable stirring rod with adjustable opening degree that can dynamically adapt to different container sizes. The stirring rod can be rotated to different positions to control the powder outlet opening, allowing the system to optimize powder flow for both small and large container openings, thereby improving versatility while preventing powder loss
Solution Approach 2:
The patent creates a universal powder dispensing system that can handle containers of various sizes through the combination of the funnel and adjustable stirring rod. The funnel serves multiple functions (collecting scattered powder, guiding powder flow), and the stirring rod provides adjustable control, making the system adaptable to different container configurations without causing powder loss
3Manufacturing precision
If powder is discharged without control mechanism, then dispensing process is simple, but powder quantity entering container does not match discharged powder
Solution Approach 1:
The patent segments the powder discharge function into multiple controllable components: the stirring rod with adjustable opening degree controls the rate and amount of powder discharge, while the funnel controls the powder flow path and collection. This segmentation allows precise control over powder quantity to ensure accurate dosing, despite the increased structural complexity

AI summary
A powder bucket and a powder dispensing device are provided. The powder bucket includes a bucket body, a stirring rod, a funnel, and a scraper. The bucket body defines a first accommodating cavity and has a powder outlet in communication with the first accommodating cavity. The stirring rod is rotatable around an axis of the stirring rod, at least partially placed in the first accommodating cavity, and configured to adjust an opening degree of the powder outlet. The funnel has one end connected to the bucket body and the other end having a powder leakage port. The powder outlet and the powder leakage port are both in communication with a second accommodating cavity defined by the funnel. The scraper is at least partially placed in the second accommodating cavity, connected to the stirring rod, and rotatable around the axis of the stirring rod following rotation of the stirring rod.
