Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder dispensing and collecting devices face issues with powder mixing and contamination, particularly when handling different types of powders, and require complex cleaning processes, which complicates operations and poses risks when handling harmful powders.
Innovation Solution
A powder collector system with a dual-filter mechanism and an automated powder collecting device that uses air intake and supply to prevent mixing through filter blocking and efficient powder handling, integrated with a robot system for automated operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single filter is used in the powder dispensing device, then the device structure is simple, but fine powder passes through the filter and mixes with subsequent powder of different kinds
Solution Approach 1:
The single filter is divided into two separate filters: a first filter for collecting powder and a second filter for preventing fine powder from passing through. This segmentation ensures that each filter has a specific function, with the first filter capturing the bulk powder and the second filter blocking fine particles that could contaminate subsequent powder batches.
Solution Approach 2:
The first filter acts as an intermediary component between the powder collection chamber and the dispensing system. It captures fine powder particles that would otherwise pass through and contaminate subsequent powder batches, thereby protecting the purity of different powder kinds.
2Adaptability or versatility
If manual cleaning is required for each powder collection, then the device can handle different powder kinds, but the work becomes significantly complicated and time-consuming
Solution Approach 1:
The filters are designed as disposable components that can be easily replaced rather than cleaned. After collecting a specific type of powder, the first filter is replaced with a new one for the next powder type, eliminating the need for manual cleaning operations and reducing contamination risks.
3Object-affected harmful factors
If automated collection is implemented for harmful powders, then safety is improved, but the system complexity increases
Solution Approach 1:
The harmful powder collection process is extracted from manual human operation and transferred to an automated robotic system. The robot performs the collection, transfer, and filter replacement operations, isolating human operators from direct exposure to harmful powders while maintaining a relatively simple overall system architecture.

AI summary
Provided is a powder collector or the like, which is capable of efficiently performing the work of collecting each powder of a different kind and the like while easily preventing a foreign matter such as another kind of powder from being mixed. The powder collector includes: a connecting part (12) having an air passage (11) that is to be removably connected to a pipe (35) for air intake and air supply; a collecting part (14) having an air passage (13) in which powder is collected to be kept through use of a suction force caused by air intake from the pipe (35) reaching the air passage (13) of the collecting part (14) through the air passage (11) of the connecting part (12) and from which the collected powder is discharged through use of a discharge force caused by air supply from the pipe (35); a first filter part (15), which is arranged at a midway position of the air passage (13) of the collecting part (14) and is configured to block passage of the powder to be collected; a relaying part (17) having an air passage (16) connecting the air passage (11) of the connecting part (12) and the collecting part (14) to each other; and a second filter part (18), which is arranged at a midway position of the air passage (16) of the relaying part (17) or in an end portion of the relaying part (17) on the connecting part (12) side, and is configured to block passage of the powder having passed through the first filter part (15).
